    University of Colorado Boulder researchers made the first-ever airborne detection of Medium Chain Chlorinated Paraffinsin the Western Hemisphere.
    Sometimes, scientific research feels a lot like solving a mystery. Scientists head into the field with a clear goal and a solid hypothesis, but then the data reveals something surprising. That’s when the real detective work begins.
    This is exactly what happened to a team from the University of Colorado Boulder during a recent field study in rural Oklahoma. They were using a state-of-the-art instrument to track how tiny particles form and grow in the air. But instead of just collecting expected data, they uncovered something completely new: the first-ever airborne detection of Medium Chain Chlorinated Paraffins, a kind of toxic organic pollutant, in the Western Hemisphere. The teams findings were published in ACS Environmental Au.
    “It’s very exciting as a scientist to find something unexpected like this that we weren’t looking for,” said Daniel Katz, CU Boulder chemistry PhD student and lead author of the study. “We’re starting to learn more about this toxic, organic pollutant that we know is out there, and which we need to understand better.”
    MCCPs are currently under consideration for regulation by the Stockholm Convention, a global treaty to protect human health from long-standing and widespread chemicals. While the toxic pollutants have been measured in Antarctica and Asia, researchers haven’t been sure how to document them in the Western Hemisphere’s atmosphere until now.
    From Wastewater to Farmlands
    MCCPs are used in fluids for metal working and in the construction of PVC and textiles. They are often found in wastewater and as a result, can end up in biosolid fertilizer, also called sewage sludge, which is created when liquid is removed from wastewater in a treatment plant. In Oklahoma, researchers suspect the MCCPs they identified came from biosolid fertilizer in the fields near where they set up their instrument.
    “When sewage sludges are spread across the fields, those toxic compounds could be released into the air,” Katz said. “We can’t show directly that that’s happening, but we think it’s a reasonable way that they could be winding up in the air. Sewage sludge fertilizers have been shown to release similar compounds.”
    MCCPs little cousins, Short Chain Chlorinated Paraffins, are currently regulated by the Stockholm Convention, and since 2009, by the EPA here in the United States. Regulation came after studies found the toxic pollutants, which travel far and last a long time in the atmosphere, were harmful to human health. But researchers hypothesize that the regulation of SCCPs may have increased MCCPs in the environment.
    “We always have these unintended consequences of regulation, where you regulate something, and then there’s still a need for the products that those were in,” said Ellie Browne, CU Boulder chemistry professor, CIRES Fellow, and co-author of the study. “So they get replaced by something.”
    Measurement of aerosols led to a new and surprising discovery
    Using a nitrate chemical ionization mass spectrometer, which allows scientists to identify chemical compounds in the air, the team measured air at the agricultural site 24 hours a day for one month. As Katz cataloged the data, he documented the different isotopic patterns in the compounds. The compounds measured by the team had distinct patterns, and he noticed new patterns that he immediately identified as different from the known chemical compounds. With some additional research, he identified them as chlorinated paraffins found in MCCPs.
    Katz says the makeup of MCCPs are similar to PFAS, long-lasting toxic chemicals that break down slowly over time. Known as “forever chemicals,” their presence in soils recently led the Oklahoma Senate to ban biosolid fertilizer.
    Now that researchers know how to measure MCCPs, the next step might be to measure the pollutants at different times throughout the year to understand how levels change each season. Many unknowns surrounding MCCPs remain, and there’s much more to learn about their environmental impacts.
    “We identified them, but we still don’t know exactly what they do when they are in the atmosphere, and they need to be investigated further,” Katz said. “I think it’s important that we continue to have governmental agencies that are capable of evaluating the science and regulating these chemicals as necessary for public health and safety.”

    The Vandenberg Space Force Base in Santa Barbara, California, serves military space launch missions as well as launches for NASA and commercial entities like SpaceX. But how do all those launches affect residents living along the Central Coast? People might marvel at the spectacular visual display, but as launch activity at the base has ramped up, so have the noise complaints, particularly about the sonic booms produced by Falcon 9 launches, which can reach as far south as Ventura County. The booms rattle windows, frighten pets, and have raised concerns about threats to the structural integrity of private homes.
    There have been rockets launching from Vandenberg for decades, so why are the Falcon 9 launches of such concern? "Because of the Starlink satellites, the orbital mechanics for where they're trying to place these in orbit is bringingcloser to the coast," said Brigham Young University's Kent Gee, who described his research into sonic boom effects on neighboring communities in a press briefing at a meeting of the Acoustical Society of America in New Orleans. And the launches are occurring much more frequently, from two to three launches per year in the 1980s to between five and seven launches each month today. There were 46 Falcon 9 launches out of the Vandenberg base in 2024 alone, per Gee.
    Gee joined a project called ECOBOOMto study the factors that can impact just how jarring those sonic booms might be, conducted jointly by BYU and California State University, Bakersfield, with cooperation from the Space Force. "Space Force is interested in this because they feel a sense of stewardship," said Gee. "These rockets from SpaceX and other providers are launched from the base for a variety of missions and they want to understand the effects both on and off base, trying to understand how they can complete the mission while minimizingimpacts."

    Gee and his cohorts monitored 132 separate sonic booms last summer, relying on data gathered via a network of 25 or so acoustic monitoring stations located along 500 square miles, including the beaches of Isla Vista and further inland to the hills of Ojai. "The measurements were made in parks, people's backyards, parking lots, wastewater plants, and all sorts of different locations," said Gee.
    More bang than boom

    There has been a great deal of research on supersonic aircraft, but the sonic booms produced by rockets like the Falcon 9 are acoustically distinct, according to Gee. For instance, most sonic booms have two shock waves, but the Falcon 9 booster produces a boom with three shocks as it descends through the atmosphere after launch. Gee co-authored a paper earlier this year analyzing the acoustic signatures of three Falcon 9 flyback sonic booms.
    While the first and third shocks were what one might typically expect, the second central shock "is formed by a combination of the grid fins and the lower portions of the booster, including the folded landing legs," Gee and BYU colleague Mark C. Anderson wrote. "These lower portions of the booster produce a rarefaction wave that tends to migrate toward the back of the shock system while the grid fins produce a shock wave that tends to migrate toward the front of the shock system." Those shock waves merge, and their relative strengths determine where this second shock appears in the full sonic boom acoustic signature.

    Sonic booms from rockets are also lower frequency, with peaks of less than 1 Hz—below the range of human hearing. The result is less of a "boom" and more of a "bang," according to Gee, that can last a few seconds, compared to milliseconds for a typical acoustic wave. It's more akin to a seismic wave, particularly if one is indoors when it hits. "Sometimes you get a very low amplitude rumble, but it comes on suddenly, and it's there for a few seconds and disappears," he said. It's also one reason why the sonic booms can travel so far afield of the Vandenberg base.

    Could the similarities confuse California residents who might mistake a sonic boom for an earthquake? Perhaps, at least until residents learn otherwise. "Since we're often setting up in people's backyard, they text us the results of what they heard," said Gee. "It's fantastic citizen science. They'll tell us the difference is that the walls shake but the floors don't. They're starting to be able to tell the difference between an earthquake or a sonic boom from a launch."

    A rocket's trajectory also plays an important role. "Everyone sees the same thing, but what you hear depends on where you're at and the rocket's path or trajectory," said Gee, adding that even the same flight path can nonetheless produce markedly different noise levels. "There's a focal region in Ventura, Oxnard, and Camarillo where the booms are more impactful," he said. "Where that focus occurs changes from launch to launch, even for the same trajectory." That points to meteorology also being a factor: Certain times of year could potentially have more impact than others as weather conditions shift, with wind shears, temperature gradients, and topography, for instance, potentially affecting the propagation of sonic booms.
    In short, "If you can change your trajectory even a little under the right meteorological conditions, you can have a big impact on the sonic booms in this region of the country," said Gee. And it's only the beginning of the project; the team is still gathering data. "No two launches look the same right now," said Gee. "It's like trying to catch lightning."
    As our understanding improves, he sees the conversation shifting to more subjective social questions, possibly leading to the development of science-based local regulations, such as noise ordinances, to address any negative launch impacts. The next step is to model sonic booms under different weather conditions, which will be challenging due to coastal California's microclimates. "If you've ever driven along the California coast, the weather changes dramatically," said Gee. "You go from complete fog at Vandenberg to complete sun in Ventura County just 60 miles from the base."

As our understanding improves, he sees the conversation shifting to more subjective social questions, possibly leading to the development of science-based local regulations, such as noise ordinances, to address any negative launch impacts. The next step is to model sonic booms under different weather conditions, which will be challenging due to coastal California's microclimates. "If you've ever driven along the California coast, the weather changes dramatically," said Gee. "You go from complete fog at Vandenberg to complete sun in Ventura County just 60 miles from the base."

    Text description provided by the architects. The Missing Room is a living space designed to encourage new rituals and patterns of use, offering an opportunity to enter an alternative time zone and experience a passage between a human-controlled environment and an untamed natural one. It is a room that has escaped the rigid confines of a defined house, choosing to exist without walls or a ceiling – a place where nature becomes the main inhabitant and visitors are invited to act as respectful guests. As one enters the Carroccera landscape, the search begins. Meandering through the land, the Missing Room gradually reveals itself, with the wanderer catching shimmering glimpses of smaller secondary structures shining through the forest greenery. This collection of visual fragments prepares the visitor for the main encounter, enriching the landscape with its enigmatic shapes and forms.this picture!this picture!this picture!The Missing Room is not simply a shelter but a space that invites discovery. A collection of abstract forms with a core activated by water and fire, it reimagines the most primal human rituals: resting, eating, cleansing, and conversing. These activities mix in unexpected yet harmonious ways. While guests cook over a crackling open fire, another inhabitant bathes in a heated bath, and a cow drinks from an integrated trough—all beneath a ceiling of tree canopies and the open sky. This space encourages visitors to set their own pace and redefine their pre-existing notions of domesticity. At the core of the Missing Room stands a seven-meter-tall monolith: a multifunctional chimney. On one side, the fire powers the ovens, while on the other, it heats water for bathing and warms the area at the front of the space. This towering form responds to the scale of the surrounding trees, rising like a beacon above the canopies, marking its presence in the landscape and guiding visitors with its smoke signals.this picture!this picture!Water, like fire, plays a central role in activating the hidden features of the structure. The water flow is released at the entrance of the structure, filling the main collection channel that distributes the flow into various basins throughout the structure. Users are encouraged to interact with the water systems by adding or removing plugs as needed to direct the flow; to fill the bath, use the sink or supply water to the cattle trough. The bath next to the water channel has a built-in natural convection system and comfortably accommodates three to four people. For solo use, the bath's size can be reduced with a partitioning panel and a removable lock to conserve water. Once closed, the bath can be transformed into a heated surface and used as a resting place to sleep at night under the stars.this picture!this picture!this picture!A bespoke sail canopy can be set up to offer shade or protection from rain. Using the chimney as a mast, the fabric is raised with a series of ropes and tensioned at the corners with ground pegs. By day, the canopy catches dappled shadows cast by the surrounding foliage; by night, it reflects light from built-in recessed lighting, transforming the structure into a glowing lantern. The Missing Room reconnects us with the rhythms of nature that have been lost in the contemporary world by reducing the act of dwelling to its very essence. Forest debris is gathered and converted into heat while the wastewater from bathing and cooking is filtered and safely dispersed into the field, providing irrigation and wet areas that contribute to the overall biodiversity of the forest.this picture!© Alessandro NanniConstructed with a focus on material and structural sustainability, the stainless steel refuge is durable, recyclable, and resistant to weathering. To protect the land, the modular structure and use of a non-invasive screw-pile foundation ensures that no traces are left behind if the house is required to be removed from the site. The Missing Room is a space for all – humans and non-humans – to share. Above all, the Carroccera Collective conceived of the room as a place to enjoy the very act of being. To invite our guests to slow down, reorient the senses, and rediscover the sensory richness and simplicity of the natural environment. As nature has vanished from our daily rituals and gone missing from our human lives, the room is a space to reveal the forgotten.this picture!

  • From Root to Roof: In Venice, ArchDaily Highlights Restorative Emerging Practices

    this picture!Pitaya House / Taller General + Jose María Sáez. Image © JAG StudioIn partnership with the European Cultural Center, ArchDaily has launched its inaugural exhibition as part of the seventh iteration of Time Space Existence, an architectural showcase occurring concurrently with the 19th Venice Architecture Biennale. Open from May 10 to November 23, 2025, in various locations throughout Venice, this edition centers on the theme of "Repair, Regenerate, and Reuse," promoting innovative and sustainable approaches in architecture. ArchDaily's contribution is located at Palazzo Mora, complementing other venues like Palazzo Bembo, Marinaressa Gardens, and Palazzo Michiel.
    this picture!this picture!Aligned with the broader theme of the event, the exhibition focuses on six emerging practices that were previously selected as part of ArchDaily's ongoing series "Best New Practices." Initiated in 2020, this annual award aims to recognize innovative professionals across various fields related to architecture, highlighting the diversity of approaches and innovations brought by creatives working at the intersection of architecture and other related domains. With over 85 teams and professionals selected to date, representing contributions from 32 countries, the initiative reflects a commitment to geographical diversity and the inclusion of regions often overshadowed in the global architectural discourse. By highlighting firms from areas such as Latin America, Africa, and Southeast Asia, the initiative brings attention to unique architectural expressions and solutions emerging from these contexts and contributing meaningfully to the global debate.this picture!The six selected practices illustrate this variety by addressing all phases of the design process, introducing innovations from the roots of material sourcing to the potential of rethinking urban rooftops. Estudio Flume in Brazil exemplifies how transforming organic waste into sustainable building materials supports regional development and cultural preservation. Willow Technologies in Ghana advocates for circular economy strategies by reusing agricultural by-products to repair ecosystems and foster biodiversity. Taller General in Ecuador promotes social inclusion through collaborative architecture that reuses existing structures and materials. Studio Zewde in the U.S. integrates ecological and cultural history into landscape design. Wiki World in China democratizes architecture by engaging communities and children in the creative process. Meanwhile, Roofscapes in France focuses on retrofitting existing urban surfaces to adapt cities to climate challenges, transforming rooftops into ecological and social assets. Related Article ArchDaily's 2024 Best New Practices Collectively, these studios showcase how thoughtful intervention at the local level can foster resilient, sustainable environments, making a significant impact through bottom-up strategies aligned with the "root to roof" philosophy.Identifying and Leveraging Local ResourcesEstudio Flume, Noelia Monteirothis picture!Estudio Flume, founded in 2015 by Noelia Monteiro and Christian Teshirogi, uniquely addresses the intersection of environmental sustainability and community empowerment by transforming organic waste from Amazonian açaí production into locally created construction materials. Focusing on discarded açaí seeds, the studio collaborates closely with local harvesters to develop particleboard panels that serve as sustainable, locally made materials for community-driven designs. This approach not only reduces waste and preserves traditional practices but also provides economic benefits to communities reliant on açaí harvesting. Through participatory workshops and tailored material research, Estudio Flume emphasizes culturally sensitive, environmentally responsible design solutions that support regional development.this picture!Their work exemplifies how innovative reuse of natural resources can foster community resilience and promote ecological balance within the Amazon. The transformation and repurposing of waste from a process essential to local communities demonstrate a grassroots approach for working within local contexts while also illustrating a particular interpretation of the themes of "Repair, Regenerate, and Reuse." The studio helps regenerate ecological balance within the Amazon, turning waste into a catalyst for both environmentally and socially responsible building practices.Restoring Balance with Circular Economy Practices Willow Technologies, Mae-ling Lokkothis picture!Founded by Ghanaian-Filipino scientist and architect Mae-Ling Lokko in 2017, Willow Technologies conducts material research and pioneers circular and bio-based technologies that root material development into regional agricultural practices. Their initiatives take a holistic look at the broader needs of local communities, not only reusing discarded bio-based waste such as coconut husks into new building materials, but also employing these materials to provide essential services. One example is their collaboration with Global Mamas to employ moringa seed press cake—a by-product of oil extraction—as a water filtration system that treats toxic textile wastewater, providing safe water for municipal disposal.this picture!Furthermore, their focus on repairing and regenerating environmental systems is evident in their efforts to develop solutions that reduce waste, improve soil health, and restore ecological balance. Projects like transforming wastewater treatment by-products into usable masonry and creating stormwater management systems demonstrate how contamination risk is minimized and ecosystems are regenerated. By closing resource loops and promoting community involvement, Willow Technologies advocates for materials and practices that repair environmental damage, support biodiversity, and foster sustainable development.Enhancing Spaces through Collective WorkTaller Generalthis picture!Taller General, founded in 2017 in Quito, Ecuador, uniquely approaches architecture through the lens of collaborative work and social transformation, while not disregarding environmental responsibility. Acting within regions defined by informal urban growth, the studio's practice understands construction as a continuous process of learning through community engagement and resource reuse. Projects such as the Pitaya House feature laminated pine from certified forests, highlighting innovations in sustainable material sourcing and reducing ecological impact, while San Tola Cohousing rehabilitates and reuses existing structures to revitalize Quito's historic center.this picture!Taller General's initiatives extend beyond physical buildings—they promote social inclusion through programs like Femingas, which encourages women and diverse groups' participation in construction. Their work demonstrates how architecture can repair urban and social landscapes while regenerating local ecosystems and communities, fostering a more inclusive and sustainable future. By blending traditional practices with innovative materials and collaborative processes, Taller General exemplifies a holistic approach to addressing urgent social and environmental challenges through architecture.Grounded Connections to Land and CultureStudio Zewdethis picture!US-based Landscape architecture and urban design Studio Zewde integrates both ecological and cultural roots into their approach to landscape design. Their work begins with understanding the land's history, indigenous relationships, and natural systems, as seen in their Cuyahoga Valley project, which reconnects underrepresented communities with the site's ecological richness and cultural legacy. The studio's design interventions organize the environment with the aim of celebrating local histories and restoring habitat and human connections grounded in regional knowledge.this picture!Exemplifying a different aspect of the "Repair, Regenerate, and Reuse" theme, Studio Zewde actively repairs ecological and social systems through thoughtful interventions that foster community participation and cultural continuity. Their work not only regenerates natural habitats and urban environments but also reimagines the landscape as a platform for civic imagination and memory. It demonstrates the power of dynamic participation and the potential of landscape architecture to promote lasting social and environmental resilience.Harnessing Collective Intelligence in ArchitectureWiki Worldthis picture!Wiki World proposes a transformative approach to architecture and architecture education rooted in community involvement and sustainability. Based in Wuhan, China, the studio democratizes the building process by engaging local residents, especially children, in designing and constructing their environments. Their projects, such as the Wiki Tribe community cabins, showcase how participatory methods can foster a sense of ownership, cultural preservation, and environmental harmony. Using traditional craftsmanship and local materials, they minimize ecological impact while revitalizing regional techniques and providing economic opportunities for artisans.this picture!By starting from the community's needs, cultural context, and local resources, the studio acts not as the creator but as a facilitator in the process of design, creating spaces that reflect collective identity. Their use of modular, prefabricated materials allows for rapid deployment, adapting to rural landscapes and seasonal activities like harvest festivals. Through a process of repair, regeneration, and reuse, Wiki World creates resilient spaces that strengthen community bonds and nurture ecological awareness, highlighting the potential of participatory design to shape culturally rich environments worldwide.Urban Roofs for Climate AdaptationRoofscapesthis picture!Roofscapes exemplifies an integrated approach to urban climate adaptation by proposing solutions for the transformation of urban surfaces, especially roofs, into elements that can regulate the microclimate and create a more resilient and comfortable urban environment. The studio focuses on underutilized rooftops, particularly in European cities like Paris, thinking of solutions to adapt an urban infrastructure originally created to conserve heat into one that actively mitigates it, thus adapting to the changing climate conditions of contemporary times. The roofing system is reimagined to incorporate green technologies such as shaded areas, vegetation, and permeable surfaces. These strategies address heat accumulation and foster cooling from the ground up, starting with the building envelope—its "roof"—and extending to urban microclimates and ecological systems.this picture!The studio's work highlights the potential for retrofitting and reimagining existing structures rather than demolition and rebuild, prioritizing sustainability and cultural preservation. By repairing and reprogramming rooftops with green infrastructure, Roofscapes not only mitigates urban heat but also regenerates biodiversity, manages stormwater, and creates accessible outdoor spaces. This comprehensive approach demonstrates how adaptive reuse and nature-based solutions serve as vital tools in shaping resilient, climate-adapted cities, further showcasing the "root to roof" approach of repair, regeneration, and reuse.this picture!Credits: Curators: Christele Harrouk, Daniela Porto, and Romullo Baratto Editorial and Project Management: Romullo Baratto Visual Concept: Miwa Negoro and Victor Delaqua Diagram Concept: Miwa Negoro We invite you to check out ArchDaily's comprehensive coverage of the 2025 Venice Biennale.This article is part of the ArchDaily Topics: What Is Future Intelligence?, proudly presented by Gendo, an AI co-pilot for Architects.

    Save this picture!Pitaya House / Taller General + Jose María Sáez. Image © JAG StudioIn partnership with the European Cultural Center (ECC), ArchDaily has launched its inaugural exhibition as part of the seventh iteration of Time Space Existence, an architectural showcase occurring concurrently with the 19th Venice Architecture Biennale. Open from May 10 to November 23, 2025, in various locations throughout Venice, this edition centers on the theme of "Repair, Regenerate, and Reuse," promoting innovative and sustainable approaches in architecture. ArchDaily's contribution is located at Palazzo Mora, complementing other venues like Palazzo Bembo, Marinaressa Gardens, and Palazzo Michiel. Save this picture!Save this picture!Aligned with the broader theme of the event, the exhibition focuses on six emerging practices that were previously selected as part of ArchDaily's ongoing series "Best New Practices." Initiated in 2020, this annual award aims to recognize innovative professionals across various fields related to architecture, highlighting the diversity of approaches and innovations brought by creatives working at the intersection of architecture and other related domains. With over 85 teams and professionals selected to date, representing contributions from 32 countries, the initiative reflects a commitment to geographical diversity and the inclusion of regions often overshadowed in the global architectural discourse. By highlighting firms from areas such as Latin America, Africa, and Southeast Asia, the initiative brings attention to unique architectural expressions and solutions emerging from these contexts and contributing meaningfully to the global debate.Save this picture!The six selected practices illustrate this variety by addressing all phases of the design process, introducing innovations from the roots of material sourcing to the potential of rethinking urban rooftops. Estudio Flume in Brazil exemplifies how transforming organic waste into sustainable building materials supports regional development and cultural preservation. Willow Technologies in Ghana advocates for circular economy strategies by reusing agricultural by-products to repair ecosystems and foster biodiversity. Taller General in Ecuador promotes social inclusion through collaborative architecture that reuses existing structures and materials. Studio Zewde in the U.S. integrates ecological and cultural history into landscape design. Wiki World in China democratizes architecture by engaging communities and children in the creative process. Meanwhile, Roofscapes in France focuses on retrofitting existing urban surfaces to adapt cities to climate challenges, transforming rooftops into ecological and social assets. Related Article ArchDaily's 2024 Best New Practices Collectively, these studios showcase how thoughtful intervention at the local level can foster resilient, sustainable environments, making a significant impact through bottom-up strategies aligned with the "root to roof" philosophy.Identifying and Leveraging Local ResourcesEstudio Flume, Noelia Monteiro [São Paulo, Brazil]Save this picture!Estudio Flume, founded in 2015 by Noelia Monteiro and Christian Teshirogi, uniquely addresses the intersection of environmental sustainability and community empowerment by transforming organic waste from Amazonian açaí production into locally created construction materials. Focusing on discarded açaí seeds, the studio collaborates closely with local harvesters to develop particleboard panels that serve as sustainable, locally made materials for community-driven designs. This approach not only reduces waste and preserves traditional practices but also provides economic benefits to communities reliant on açaí harvesting. Through participatory workshops and tailored material research, Estudio Flume emphasizes culturally sensitive, environmentally responsible design solutions that support regional development.Save this picture!Their work exemplifies how innovative reuse of natural resources can foster community resilience and promote ecological balance within the Amazon. The transformation and repurposing of waste from a process essential to local communities demonstrate a grassroots approach for working within local contexts while also illustrating a particular interpretation of the themes of "Repair, Regenerate, and Reuse." The studio helps regenerate ecological balance within the Amazon, turning waste into a catalyst for both environmentally and socially responsible building practices.Restoring Balance with Circular Economy Practices Willow Technologies, Mae-ling Lokko [Accra, Ghana]Save this picture!Founded by Ghanaian-Filipino scientist and architect Mae-Ling Lokko in 2017, Willow Technologies conducts material research and pioneers circular and bio-based technologies that root material development into regional agricultural practices. Their initiatives take a holistic look at the broader needs of local communities, not only reusing discarded bio-based waste such as coconut husks into new building materials, but also employing these materials to provide essential services. One example is their collaboration with Global Mamas to employ moringa seed press cake—a by-product of oil extraction—as a water filtration system that treats toxic textile wastewater, providing safe water for municipal disposal.Save this picture!Furthermore, their focus on repairing and regenerating environmental systems is evident in their efforts to develop solutions that reduce waste, improve soil health, and restore ecological balance. Projects like transforming wastewater treatment by-products into usable masonry and creating stormwater management systems demonstrate how contamination risk is minimized and ecosystems are regenerated. By closing resource loops and promoting community involvement, Willow Technologies advocates for materials and practices that repair environmental damage, support biodiversity, and foster sustainable development.Enhancing Spaces through Collective WorkTaller General [Quito, Ecuador]Save this picture!Taller General, founded in 2017 in Quito, Ecuador, uniquely approaches architecture through the lens of collaborative work and social transformation, while not disregarding environmental responsibility. Acting within regions defined by informal urban growth, the studio's practice understands construction as a continuous process of learning through community engagement and resource reuse. Projects such as the Pitaya House feature laminated pine from certified forests, highlighting innovations in sustainable material sourcing and reducing ecological impact, while San Tola Cohousing rehabilitates and reuses existing structures to revitalize Quito's historic center.Save this picture!Taller General's initiatives extend beyond physical buildings—they promote social inclusion through programs like Femingas, which encourages women and diverse groups' participation in construction. Their work demonstrates how architecture can repair urban and social landscapes while regenerating local ecosystems and communities, fostering a more inclusive and sustainable future. By blending traditional practices with innovative materials and collaborative processes, Taller General exemplifies a holistic approach to addressing urgent social and environmental challenges through architecture.Grounded Connections to Land and CultureStudio Zewde [New York, United States]Save this picture!US-based Landscape architecture and urban design Studio Zewde integrates both ecological and cultural roots into their approach to landscape design. Their work begins with understanding the land's history, indigenous relationships, and natural systems, as seen in their Cuyahoga Valley project, which reconnects underrepresented communities with the site's ecological richness and cultural legacy. The studio's design interventions organize the environment with the aim of celebrating local histories and restoring habitat and human connections grounded in regional knowledge.Save this picture!Exemplifying a different aspect of the "Repair, Regenerate, and Reuse" theme, Studio Zewde actively repairs ecological and social systems through thoughtful interventions that foster community participation and cultural continuity. Their work not only regenerates natural habitats and urban environments but also reimagines the landscape as a platform for civic imagination and memory. It demonstrates the power of dynamic participation and the potential of landscape architecture to promote lasting social and environmental resilience.Harnessing Collective Intelligence in ArchitectureWiki World [Wuhan, China]Save this picture!Wiki World proposes a transformative approach to architecture and architecture education rooted in community involvement and sustainability. Based in Wuhan, China, the studio democratizes the building process by engaging local residents, especially children, in designing and constructing their environments. Their projects, such as the Wiki Tribe community cabins, showcase how participatory methods can foster a sense of ownership, cultural preservation, and environmental harmony. Using traditional craftsmanship and local materials, they minimize ecological impact while revitalizing regional techniques and providing economic opportunities for artisans.Save this picture!By starting from the community's needs, cultural context, and local resources, the studio acts not as the creator but as a facilitator in the process of design, creating spaces that reflect collective identity. Their use of modular, prefabricated materials allows for rapid deployment, adapting to rural landscapes and seasonal activities like harvest festivals. Through a process of repair, regeneration, and reuse, Wiki World creates resilient spaces that strengthen community bonds and nurture ecological awareness, highlighting the potential of participatory design to shape culturally rich environments worldwide.Urban Roofs for Climate AdaptationRoofscapes [Paris, France]Save this picture!Roofscapes exemplifies an integrated approach to urban climate adaptation by proposing solutions for the transformation of urban surfaces, especially roofs, into elements that can regulate the microclimate and create a more resilient and comfortable urban environment. The studio focuses on underutilized rooftops, particularly in European cities like Paris, thinking of solutions to adapt an urban infrastructure originally created to conserve heat into one that actively mitigates it, thus adapting to the changing climate conditions of contemporary times. The roofing system is reimagined to incorporate green technologies such as shaded areas, vegetation, and permeable surfaces. These strategies address heat accumulation and foster cooling from the ground up, starting with the building envelope—its "roof"—and extending to urban microclimates and ecological systems.Save this picture!The studio's work highlights the potential for retrofitting and reimagining existing structures rather than demolition and rebuild, prioritizing sustainability and cultural preservation. By repairing and reprogramming rooftops with green infrastructure, Roofscapes not only mitigates urban heat but also regenerates biodiversity, manages stormwater, and creates accessible outdoor spaces.

  • 9 (Somewhat) Unconventional Takes on The Beloved Spiral Staircase

    Got a project that’s too contemporary for your client? Submit your conceptual works, images and ideas for global recognition and print publication in the 2025 Vision Awards! The clock is ticking — submit your work ahead of the Main Entry deadline on June 6th.
    Spiral staircases are famously beautiful but notoriously tricky to design, particularly in section.Still, the payoff is worth it. Beyond their visual appeal, spiral stairs can save space, guide circulation, and even become striking centerpieces within a building.
    The projects below prove there’s more than one way to embrace the twist, using unexpected materials and creative details to shape spaces in offices, schools, restaurants and parks. Even when things get complicated, these nine stairs make a strong case for taking the spiral route.

    OFFICE @ 63
    By Sanjay Puri Architects, Navi Mumbai, India
    Popular Choice Winner, 12th Annual A+Awards, Commercial InteriorsA curved steel staircase rises through the center of this workplace, connecting three levels in one continuous movement. Perforated and matte-finished, it feels both solid and light. Its underside, lined with warm tones, softens the otherwise industrial palette.
    Set within a tall, multipurpose space used for exhibitions and gatherings, the stair becomes a quiet focal point. Surrounded by concrete, cork, glass and exposed metal, it stands out not just as a route between floors, but as an element that gives the entire space rhythm and focus.

    By Le studio REV, Paris, France
    At the center of Carita’s Paris beauty house, part of the L’Oréal portfolio, a curved staircase rises through what was once a closed courtyard. The space is now topped with a tall glass roof that brings in soft, natural light. Pale marble, pink onyx and brushed metal set a quiet, polished tone. The staircase is kept light with floating steps and slim supports. It connects the levels clearly and efficiently, without blocking views through arched openings. In a building designed around care and detail, the stair adds just the right touch of structure and calm movement.

    Sjustjärnan, New Nordic Headquarters for E.On
    By Kanozi Arkitekter, Malmö, Sweden
    A wide, open staircase connects the floors of E.ON’s Malmö headquarters, rising through a central glass atrium that joins the two curved volumes of the building. Designed to encourage movement and connection between departments, the stair is placed at the heart of shared circulation. Materials are simple and natural: light wood treads, glass balustrades and metal accents, chosen to support the building’s focus on well-being and daylight. Generous landings allow for pauses and casual interaction, reinforcing the workplace’s flexible layout. With no assigned desks and no divided entrances, the building encourages a sense of togetherness and the staircase plays a clear role in making that daily flow visible and accessible.

    The Learning Center at Quest
    By KSM Architecture, Chennai, India
    Jury Winner, 12th Annual A+Awards, Architecture +Learning
    A vivid red spiral staircase rises along the facade of this learning center in Chennai, connecting the top floor library to a rooftop cafeteria and terrace. Attached to the exterior, the stair adds a moment of surprise to the otherwise calm, ribbed concrete surface. Made from perforated metal, its bright finish contrasts with the muted palette of the building while echoing the colorful window frames scattered across the elevation.
    Inside, a separate metal stair winds through a central atrium, linking five stacked classrooms and open learning spaces. Together, the staircases reflect the school’s focus on movement, openness and curiosity — key principles in its interest-based approach to education.

    Varee Valley Restaurant : Jungle Junction
    By NPDA studio, Thailand
    Inside this forest-side restaurant in Northeast Thailand, a white spiral staircase rises slowly through the center of a light-filled dining area. Designed for pause and perspective, the stair leads visitors to a rooftop platform that opens up to the surrounding trees. Built with slender steel members and a delicate footprint, it reflects the lightness of the overall structure and mirrors the verticality of nearby tree trunks. The stair wraps around a central cylindrical column that also serves as a rainwater drain and light shaft, drawing daylight into the heart of the space.

    The Opera Park
    By Cobe, Copenhagen, Denmark
    Jury Winner, Public Parks & Green Spaces, 12th Annual A+Awards
    At the heart of this new harbor front park in Copenhagen, a spiral staircase descends through the center of a circular greenhouse, wrapping gently around a subtropical garden. The stair connects the café at park level with an underground parking facility, guiding visitors down through layers of greenery.
    Slim metal railings trace its curve, while the surrounding glass enclosure creates the feeling of walking through an open-air terrarium. The park itself spans six themed gardens across a former industrial island, offering paths, ponds and planting from around the world. In this setting, the staircase becomes part of a wider idea: architecture that supports slow movement, seasonal change and a close connection to nature.

    Balmy Palmy
    By CplusC Architects + Builders, Sydney, Australia
    In this compact holiday home raised above a rocky slope, a yellow spiral staircase links the natural ground to the open-air platform above. Built from powder-coated steel, it curves tightly between tree trunks and timber posts, bringing a sharp contrast to the greens and browns of the site.
    The stair leads into an outdoor area that connects the home’s simple rooms, with views of the treetops, the bay and the sky shifting between the leaves. Designed to limit excavation and preserve the forest setting, the staircase plays a clear role in the project’s minimal footprint — serving as a key access point and everyday reminder of the landscape it rises from.

  • The data center boom in the desert

    In the high desert east of Reno, Nevada, construction crews are flattening the golden foothills of the Virginia Range, laying the foundations of a data center city. Google, Tract, Switch, EdgeCore, Novva, Vantage, and PowerHouse are all operating, building, or expanding huge facilities within the Tahoe Reno Industrial Center, a business park bigger than the city of Detroit.  This story is a part of MIT Technology Review’s series “Power Hungry: AI and our energy future,” on the energy demands and carbon costs of the artificial-intelligence revolution. Meanwhile, Microsoft acquired more than 225 acres of undeveloped property within the center and an even larger plot in nearby Silver Springs, Nevada. Apple is expanding its data center, located just across the Truckee River from the industrial park. OpenAI has said it’s considering building a data center in Nevada as well. The corporate race to amass computing resources to train and run artificial intelligence models and store information in the cloud has sparked a data center boom in the desert—just far enough away from Nevada’s communities to elude wide notice and, some fear, adequate scrutiny.  Switch, a data center company based in Las Vegas, says the full build-out of its campus at the Tahoe Reno Industrial Center could exceed seven million square feet.EMILY NAJERA The full scale and potential environmental impacts of the developments aren’t known, because the footprint, energy needs, and water requirements are often closely guarded corporate secrets. Most of the companies didn’t respond to inquiries from MIT Technology Review, or declined to provide additional information about the projects.  But there’s “a whole lot of construction going on,” says Kris Thompson, who served as the longtime project manager for the industrial center before stepping down late last year. “The last number I heard was 13 million square feet under construction right now, which is massive.”
    Indeed, it’s the equivalent of almost five Empire State Buildings laid out flat. In addition, public filings from NV Energy, the state’s near-monopoly utility, reveal that a dozen data-center projects, mostly in this area, have requested nearly six gigawatts of electricity capacity within the next decade.  That would make the greater Reno area—the biggest little city in the world—one of the largest data-center markets around the globe.
    It would also require expanding the state’s power sector by about 40%, all for a single industry in an explosive growth stage that may, or may not, prove sustainable. The energy needs, in turn, suggest those projects could consume billions of gallons of water per year, according to an analysis conducted for this story.  Construction crews are busy building data centers throughout the Tahoe Reno Industrial Center.EMILY NAJERA The build-out of a dense cluster of energy and water-hungry data centers in a small stretch of the nation’s driest state, where climate change is driving up temperatures faster than anywhere else in the country, has begun to raise alarms among water experts, environmental groups, and residents. That includes members of the Pyramid Lake Paiute Tribe, whose namesake water body lies within their reservation and marks the end point of the Truckee River, the region’s main source of water. Much of Nevada has suffered through severe drought conditions for years, farmers and communities are drawing down many of the state’s groundwater reservoirs faster than they can be refilled, and global warming is sucking more and more moisture out of the region’s streams, shrubs, and soils. “Telling entities that they can come in and stick more straws in the ground for data centers is raising a lot of questions about sound management,” says Kyle Roerink, executive director of the Great Basin Water Network, a nonprofit that works to protect water resources throughout Nevada and Utah.  “We just don’t want to be in a situation where the tail is wagging the dog,” he later added, “where this demand for data centers is driving water policy.” Luring data centers In the late 1850s, the mountains southeast of Reno began enticing prospectors from across the country, who hoped to strike silver or gold in the famed Comstock Lode. But Storey County had few residents or economic prospects by the late 1990s, around the time when Don Roger Norman, a media-shy real estate speculator, spotted a new opportunity in the sagebrush-covered hills. 
    He began buying up tens of thousands of acres of land for tens of millions of dollars and lining up development approvals to lure industrial projects to what became the Tahoe Reno Industrial Center. His partners included Lance Gilman, a cowboy-hat-wearing real estate broker, who later bought the nearby Mustang Ranch brothel and won a seat as a county commissioner. In 1999, the county passed an ordinance that preapproves companies to develop most types of commercial and industrial projects across the business park, cutting months to years off the development process. That helped cinch deals with a flock of tenants looking to build big projects fast, including Walmart, Tesla, and Redwood Materials. Now the promise of fast permits is helping to draw data centers by the gigawatt. On a clear, cool January afternoon, Brian Armon, a commercial real estate broker who leads the industrial practices group at NAI Alliance, takes me on a tour of the projects around the region, which mostly entails driving around the business center. Lance Gilman, a local real estate broker, helped to develop the Tahoe Reno Industrial Center and land some of its largest tenants.GREGG SEGAL After pulling off Interstate 80 onto USA Parkway, he points out the cranes, earthmovers, and riprap foundations, where a variety of data centers are under construction. Deeper into the industrial park, Armon pulls up near Switch’s long, low, arched-roof facility, which sits on a terrace above cement walls and security gates. The Las Vegas–based company says the first phase of its data center campus encompasses more than a million square feet, and that the full build-out will cover seven times that space. 
    Over the next hill, we turn around in Google’s parking lot. Cranes, tents, framing, and construction equipment extend behind the company’s existing data center, filling much of the 1,210-acre lot that the search engine giant acquired in 2017. Last August, during an event at the University of Nevada, Reno, the company announced it would spend million to expand the data center campus along with another one in Las Vegas. Thompson says that the development company, Tahoe Reno Industrial LLC, has now sold off every parcel of developable land within the park. When I ask Armon what’s attracting all the data centers here, he starts with the fast approvals but cites a list of other lures as well: The inexpensive land. NV Energy’s willingness to strike deals to supply relatively low-cost electricity. Cool nighttime and winter temperatures, as far as American deserts go, which reduce the energy and water needs. The proximity to tech hubs such as Silicon Valley, which cuts latency for applications in which milliseconds matter. And the lack of natural disasters that could shut down the facilities, at least for the most part.
    “We are high in seismic activity,” he says. “But everything else is good. We’re not going to have a tornado or flood or a devastating wildfire.” Then there’s the generous tax policies.In 2023, Novva, a Utah-based data center company, announced plans to build a 300,000-square-foot facility within the industrial business park. Nevada doesn’t charge corporate income tax, and it has also enacted deep tax cuts specifically for data centers that set up shop in the state. That includes abatements of up to 75% on property tax for a decade or two—and nearly as much of a bargain on the sales and use taxes applied to equipment purchased for the facilities. Data centers don’t require many permanent workers to run the operations, but the projects have created thousands of construction jobs. They’re also helping to diversify the region’s economy beyond casinos and generating tax windfalls for the state, counties, and cities, says Jeff Sutich, executive director of the Northern Nevada Development Authority. Indeed, just three data-center projects, developed by Apple, Google, and Vantage, will produce nearly half a billion dollars in tax revenue for Nevada, even with those generous abatements, according to the Nevada Governor’s Office of Economic Development. The question is whether the benefits of data centers are worth the tradeoffs for Nevadans, given the public health costs, greenhouse-gas emissions, energy demands, and water strains. The rain shadow The Sierra Nevada’s granite peaks trace the eastern edge of California, forcing Pacific Ocean winds to rise and cool. That converts water vapor in the air into the rain and snow that fill the range’s tributaries, rivers, and lakes.  But the same meteorological phenomenon casts a rain shadow over much of neighboring Nevada, forming an arid expanse known as the Great Basin Desert. The state receives about 10 inches of precipitation a year, about a third of the national average.
    The Truckee River draws from the melting Sierra snowpack at the edge of Lake Tahoe, cascades down the range, and snakes through the flatlands of Reno and Sparks. It forks at the Derby Dam, a Reclamation Act project a few miles from the Tahoe Reno Industrial Center, which diverts water to a farming region further east while allowing the rest to continue north toward Pyramid Lake.  Along the way, an engineered system of reservoirs, canals, and treatment plants divert, store, and release water from the river, supplying businesses, cities, towns, and native tribes across the region. But Nevada’s population and economy are expanding, creating more demands on these resources even as they become more constrained. 
    The Truckee River, which originates at Lake Tahoe and terminates at Pyramid Lake, is the major water source for cities, towns, and farms across northwestern Nevada.EMILY NAJERA Throughout much of the 2020s the state has suffered through one of the hottest and most widespread droughts on record, extending two decades of abnormally dry conditions across the American West. Some scientists fear it may constitute an emerging megadrought.  About 50% of Nevada currently faces moderate to exceptional drought conditions. In addition, more than half of the state’s hundreds of groundwater basins are already “over-appropriated,” meaning the water rights on paper exceed the levels believed to be underground.  It’s not clear if climate change will increase or decrease the state’s rainfall levels, on balance. But precipitation patterns are expected to become more erratic, whiplashing between short periods of intense rainfall and more-frequent, extended, or severe droughts.  In addition, more precipitation will fall as rain rather than snow, shortening the Sierra snow season by weeks to months over the coming decades.  “In the extreme case, at the end of the century, that’s pretty much all of winter,” says Sean McKenna, executive director of hydrologic sciences at the Desert Research Institute, a research division of the Nevada System of Higher Education. That loss will undermine an essential function of the Sierra snowpack: reliably delivering water to farmers and cities when it’s most needed in the spring and summer, across both Nevada and California.  These shifting conditions will require the region to develop better ways to store, preserve, and recycle the water it does get, McKenna says. Northern Nevada’s cities, towns, and agencies will also need to carefully evaluate and plan for the collective impacts of continuing growth and development on the interconnected water system, particularly when it comes to water-hungry projects like data centers, he adds. “We can’t consider each of these as a one-off, without considering that there may be tens or dozens of these in the next 15 years,” McKenna says.Thirsty data centers Data centers suck up water in two main ways.
    As giant rooms of server racks process information and consume energy, they generate heat that must be shunted away to prevent malfunctions and damage to the equipment. The processing units optimized for training and running AI models often draw more electricity and, in turn, produce more heat. To keep things cool, more and more data centers have turned to liquid cooling systems that don’t need as much electricity as fan cooling or air-conditioning. These often rely on water to absorb heat and transfer it to outdoor cooling towers, where much of the moisture evaporates. Microsoft’s US data centers, for instance, could have directly evaporated nearly 185,000 gallons of “clean freshwater” in the course of training OpenAI’s GPT-3 large language model, according to a 2023 preprint study led by researchers at the University of California, Riverside.What’s less appreciated, however, is that the larger data-center drain on water generally occurs indirectly, at the power plants generating extra electricity for the turbocharged AI sector. These facilities, in turn, require more water to cool down equipment, among other purposes. You have to add up both uses “to reflect the true water cost of data centers,” says Shaolei Ren, an associate professor of electrical and computer engineering at UC Riverside and coauthor of the study. Ren estimates that the 12 data-center projects listed in NV Energy’s report would directly consume between 860 million gallons and 5.7 billion gallons a year, based on the requested electricity capacity.The indirect water drain associated with electricity generation for those operations could add up to 15.5 billion gallons, based on the average consumption of the regional grid. The exact water figures would depend on shifting climate conditions, the type of cooling systems each data center uses, and the mix of power sources that supply the facilities. Solar power, which provides roughly a quarter of Nevada’s power, requires relatively little water to operate, for instance. But natural-gas plants, which generate about 56%, withdraw 2,803 gallons per megawatt-hour on average, according to the Energy Information Administration.  Geothermal plants, which produce about 10% of the state’s electricity by cycling water through hot rocks, generally consume less water than fossil fuel plants do but often require more water than other renewables, according to some research.  But here too, the water usage varies depending on the type of geothermal plant in question. Google has lined up several deals to partially power its data centers through Fervo Energy, which has helped to commercialize an emerging approach that injects water under high pressure to fracture rock and form wells deep below the surface.  The company stresses that it doesn’t evaporate water for cooling and that it relies on brackish groundwater, not fresh water, to develop and run its plants. In a recent post, Fervo noted that its facilities consume significantly less water per megawatt-hour than coal, nuclear, or natural-gas plants do. Part of NV Energy’s proposed plan to meet growing electricity demands in Nevada includes developing several natural-gas peaking units, adding more than one gigawatt of solar power and installing another gigawatt of battery storage. It's also forging ahead with a more than billion transmission project. But the company didn’t respond to questions concerning how it will supply all of the gigawatts of additional electricity requested by data centers, if the construction of those power plants will increase consumer rates, or how much water those facilities are expected to consume. NV Energy operates a transmission line, substation, and power plant in or around the Tahoe Reno Industrial Center.EMILY NAJERA “NV Energy teams work diligently on our long-term planning to make investments in our infrastructure to serve new customers and the continued growth in the state without putting existing customers at risk,” the company said in a statement. An added challenge is that data centers need to run around the clock. That will often compel utilities to develop new electricity-generating sources that can run nonstop as well, as natural-gas, geothermal, or nuclear plants do, says Emily Grubert, an associate professor of sustainable energy policy at the University of Notre Dame, who has studied the relative water consumption of electricity sources.  “You end up with the water-intensive resources looking more important,” she adds. Even if NV Energy and the companies developing data centers do strive to power them through sources with relatively low water needs, “we only have so much ability to add six gigawatts to Nevada’s grid,” Grubert explains. “What you do will never be system-neutral, because it’s such a big number.” Securing supplies On a mid-February morning, I meet TRI’s Thompson and Don Gilman, Lance Gilman’s son, at the Storey County offices, located within the industrial center.  “I’m just a country boy who sells dirt,” Gilman, also a real estate broker, says by way of introduction.  We climb into his large SUV and drive to a reservoir in the heart of the industrial park, filled nearly to the lip.  Thompson explains that much of the water comes from an on-site treatment facility that filters waste fluids from companies in the park. In addition, tens of millions of gallons of treated effluent will also likely flow into the tank this year from the Truckee Meadows Water Authority Reclamation Facility, near the border of Reno and Sparks. That’s thanks to a 16-mile pipeline that the developers, the water authority, several tenants, and various local cities and agencies partnered to build, through a project that began in 2021. “Our general improvement district is furnishing that water to tech companies here in the park as we speak,” Thompson says. “That helps preserve the precious groundwater, so that is an environmental feather in the cap for these data centers. They are focused on environmental excellence.” The reservoir within the industrial business park provides water to data centers and other tenants.EMILY NAJERA But data centers often need drinking-quality water—not wastewater merely treated to irrigation standards—for evaporative cooling, “to avoid pipe clogs and/or bacterial growth,” the UC Riverside study notes. For instance, Google says its data centers withdrew about 7.7 billion gallons of water in 2023, and nearly 6 billion of those gallons were potable.  Tenants in the industrial park can potentially obtain access to water from the ground and the Truckee River, as well. From early on, the master developers worked hard to secure permits to water sources, since they are nearly as precious as development entitlements to companies hoping to build projects in the desert. Initially, the development company controlled a private business, the TRI Water and Sewer Company, that provided those services to the business park’s tenants, according to public documents. The company set up wells, a water tank, distribution lines, and a sewer disposal system.  But in 2000, the board of county commissioners established a general improvement district, a legal mechanism for providing municipal services in certain parts of the state, to manage electricity and then water within the center. It, in turn, hired TRI Water and Sewer as the operating company. As of its 2020 service plan, the general improvement district held permits for nearly 5,300 acre-feet of groundwater, “which can be pumped from well fields within the service area and used for new growth as it occurs.” The document lists another 2,000 acre-feet per year available from the on-site treatment facility, 1,000 from the Truckee River, and 4,000 more from the effluent pipeline.  Those figures haven’t budged much since, according to Shari Whalen, general manager of the TRI General Improvement District. All told, they add up to more than 4 billion gallons of water per year for all the needs of the industrial park and the tenants there, data centers and otherwise. Whalen says that the amount and quality of water required for any given data center depends on its design, and that those matters are worked out on a case-by-case basis.  When asked if the general improvement district is confident that it has adequate water resources to supply the needs of all the data centers under development, as well as other tenants at the industrial center, she says: “They can’t just show up and build unless they have water resources designated for their projects. We wouldn’t approve a project if it didn’t have those water resources.” Water As the region’s water sources have grown more constrained, lining up supplies has become an increasingly high-stakes and controversial business. More than a century ago, the US federal government filed a lawsuit against an assortment of parties pulling water from the Truckee River. The suit would eventually establish that the Pyramid Lake Paiute Tribe’s legal rights to water for irrigation superseded other claims. But the tribe has been fighting to protect those rights and increase flows from the river ever since, arguing that increasing strains on the watershed from upstream cities and businesses threaten to draw away water reserved for reservation farming, decrease lake levels, and harm native fish. The Pyramid Lake Paiute Tribe considers the water body and its fish, including the endangered cui-ui and threatened Lahontan cutthroat trout, to be essential parts of its culture, identity, and way of life. The tribe was originally named Cui-ui Ticutta, which translates to cui-ui eaters. The lake continues to provide sustenance as well as business for the tribe and its members, a number of whom operate boat charters and fishing guide services. “It’s completely tied into us as a people,” says Steven Wadsworth, chairman of the Pyramid Lake Paiute Tribe. “That is what has sustained us all this time,” he adds. “It’s just who we are. It’s part of our spiritual well-being.” Steven Wadsworth, chairman of the Pyramid Lake Paiute Tribe, fears that data centers will divert water that would otherwise reach the tribe’s namesake lake.EMILY NAJERA In recent decades, the tribe has sued the Nevada State Engineer, Washoe County, the federal government, and others for overallocating water rights and endangering the lake’s fish. It also protested the TRI General Improvement District’s applications to draw thousands of additional acre‑feet of groundwater from a basin near the business park. In 2019, the State Engineer’s office rejected those requests, concluding that the basin was already fully appropriated.  More recently, the tribe took issue with the plan to build the pipeline and divert effluent that would have flown into the Truckee, securing an agreement that required the Truckee Meadows Water Authority and other parties to add back several thousand acre‑feet of water to the river.  Whalen says she’s sensitive to Wadsworth’s concerns. But she says that the pipeline promises to keep a growing amount of treated wastewater out of the river, where it could otherwise contribute to rising salt levels in the lake. “I think that the pipeline fromto our system is good for water quality in the river,” she says. “I understand philosophically the concerns about data centers, but the general improvement district is dedicated to working with everyone on the river for regional water-resource planning—and the tribe is no exception.” Water efficiency  In an email, Thompson added that he has “great respect and admiration,” for the tribe and has visited the reservation several times in an effort to help bring industrial or commercial development there. He stressed that all of the business park’s groundwater was “validated by the State Water Engineer,” and that the rights to surface water and effluent were purchased “for fair market value.”During the earlier interview at the industrial center, he and Gilman had both expressed confidence that tenants in the park have adequate water supplies, and that the businesses won’t draw water away from other areas.  “We’re in our own aquifer, our own water basin here,” Thompson said. “You put a straw in the ground here, you’re not going to pull water from Fernley or from Reno or from Silver Springs.” Gilman also stressed that data-center companies have gotten more water efficient in recent years, echoing a point others made as well. “With the newer technology, it’s not much of a worry,” says Sutich, of the Northern Nevada Development Authority. “The technology has come a long way in the last 10 years, which is really giving these guys the opportunity to be good stewards of water usage.” An aerial view of the cooling tower fans at Google’s data center in the Tahoe Reno Industrial Center.GOOGLE Indeed, Google’s existing Storey County facility is air-cooled, according to the company’s latest environmental report. The data center withdrew 1.9 million gallons in 2023 but only consumed 200,000 gallons. The rest cycles back into the water system. Google said all the data centers under construction on its campus will also “utilize air-cooling technology.” The company didn’t respond to a question about the scale of its planned expansion in the Tahoe Reno Industrial Center, and referred a question about indirect water consumption to NV Energy. The search giant has stressed that it strives to be water efficient across all of its data centers, and decides whether to use air or liquid cooling based on local supply and projected demand, among other variables. Four years ago, the company set a goal of replenishing more water than it consumes by 2030. Locally, it also committed to provide half a million dollars to the National Forest Foundation to improve the Truckee River watershed and reduce wildfire risks.  Microsoft clearly suggested in earlier news reports that the Silver Springs land it purchased around the end of 2022 would be used for a data center. NAI Alliance’s market real estate report identifies that lot, as well as the parcel Microsoft purchased within the Tahoe Reno Industrial Center, as data center sites. But the company now declines to specify what it intends to build in the region.  “While the land purchase is public knowledge, we have not disclosed specific detailsour plans for the land or potential development timelines,” wrote Donna Whitehead, a Microsoft spokesperson, in an email.  Workers have begun grading land inside a fenced off lot within the Tahoe Reno Industrial Center.EMILY NAJERA Microsoft has also scaled down its global data-center ambitions, backing away from several projects in recent months amid shifting economic conditions, according to various reports. Whatever it ultimately does or doesn’t build, the company stresses that it has made strides to reduce water consumption in its facilities. Late last year, the company announced that it’s using “chip-level cooling solutions” in data centers, which continually circulate water between the servers and chillers through a closed loop that the company claims doesn’t lose any water to evaporation. It says the design requires only a “nominal increase” in energy compared to its data centers that rely on evaporative water cooling. Others seem to be taking a similar approach. EdgeCore also said its 900,000-square-foot data center at the Tahoe Reno Industrial Center will rely on an “air-cooled closed-loop chiller” that doesn’t require water evaporation for cooling.  But some of the companies seem to have taken steps to ensure access to significant amounts of water. Switch, for instance, took a lead role in developing the effluent pipeline. In addition, Tract, which develops campuses on which third-party data centers can build their own facilities, has said it lined up more than 1,100 acre-feet of water rights, the equivalent of nearly 360 million gallons a year.  Apple, Novva, Switch, Tract, and Vantage didn’t respond to inquiries from MIT Technology Review.  Coming conflicts  The suggestion that companies aren’t straining water supplies when they adopt air cooling is, in many cases, akin to saying they’re not responsible for the greenhouse gas produced through their power use simply because it occurs outside of their facilities. In fact, the additional water used at a power plant to meet the increased electricity needs of air cooling may exceed any gains at the data center, Ren, of UC Riverside, says. “That’s actually very likely, because it uses a lot more energy,” he adds. That means that some of the companies developing data centers in and around Storey County may simply hand off their water challenges to other parts of Nevada or neighboring states across the drying American West, depending on where and how the power is generated, Ren says.  Google has said its air-cooled facilities require about 10% more electricity, and its environmental report notes that the Storey County facility is one of its two least-energy-efficient data centers.  Pipes running along Google’s data center campus help the search company cool its servers.GOOGLE Some fear there’s also a growing mismatch between what Nevada’s water permits allow, what’s actually in the ground, and what nature will provide as climate conditions shift. Notably, the groundwater committed to all parties from the Tracy Segment basin—a long-fought-over resource that partially supplies the TRI General Improvement District—already exceeds the “perennial yield.” That refers to the maximum amount that can be drawn out every year without depleting the reservoir over the long term. “If pumping does ultimately exceed the available supply, that means there will be conflict among users,” Roerink, of the Great Basin Water Network, said in an email. “So I have to wonder: Who could be suing whom? Who could be buying out whom? How will the tribe’s rights be defended?”The Truckee Meadows Water Authority, the community-owned utility that manages the water system for Reno and Sparks, said it is planning carefully for the future and remains confident there will be “sufficient resources for decades to come,” at least within its territory east of the industrial center. Storey County, the Truckee-Carson Irrigation District, and the State Engineer’s office didn’t respond to questions or accept interview requests.  Open for business As data center proposals have begun shifting into Northern Nevada’s cities, more local residents and organizations have begun to take notice and express concerns. The regional division of the Sierra Club, for instance, recently sought to overturn the approval of Reno’s first data center, about 20 miles west of the Tahoe Reno Industrial Center.  Olivia Tanager, director of the Sierra Club’s Toiyabe Chapter, says the environmental organization was shocked by the projected electricity demands from data centers highlighted in NV Energy’s filings. Nevada’s wild horses are a common sight along USA Parkway, the highway cutting through the industrial business park. EMILY NAJERA “We have increasing interest in understanding the impact that data centers will have to our climate goals, to our grid as a whole, and certainly to our water resources,” she says. “The demands are extraordinary, and we don’t have that amount of water to toy around with.” During a city hall hearing in January that stretched late into the evening, she and a line of residents raised concerns about the water, energy, climate, and employment impacts of AI data centers. At the end, though, the city council upheld the planning department’s approval of the project, on a 5-2 vote. “Welcome to Reno,” Kathleen Taylor, Reno’s vice mayor, said before casting her vote. “We’re open for business.” Where the river ends In late March, I walk alongside Chairman Wadsworth, of the Pyramid Lake Paiute Tribe, on the shores of Pyramid Lake, watching a row of fly-fishers in waders cast their lines into the cold waters.  The lake is the largest remnant of Lake Lahontan, an Ice Age inland sea that once stretched across western Nevada and would have submerged present-day Reno. But as the climate warmed, the lapping waters retreated, etching erosional terraces into the mountainsides and exposing tufa deposits around the lake, large formations of porous rock made of calcium-carbonate. That includes the pyramid-shaped island on the eastern shore that inspired the lake’s name. A lone angler stands along the shores of Pyramid Lake. In the decades after the US Reclamation Service completed the Derby Dam in 1905, Pyramid Lake declined another 80 feet and nearby Winnemucca Lake dried up entirely. “We know what happens when water use goes unchecked,” says Wadsworth, gesturing eastward toward the range across the lake, where Winnemucca once filled the next basin over. “Because all we have to do is look over there and see a dry, barren lake bed that used to be full.”In an earlier interview, Wadsworth acknowledged that the world needs data centers. But he argued they should be spread out across the country, not densely clustered in the middle of the Nevada desert.Given the fierce competition for resources up to now, he can’t imagine how there could be enough water to meet the demands of data centers, expanding cities, and other growing businesses without straining the limited local supplies that should, by his accounting, flow to Pyramid Lake. He fears these growing pressures will force the tribe to wage new legal battles to protect their rights and preserve the lake, extending what he refers to as “a century of water wars.” “We have seen the devastating effects of what happens when you mess with Mother Nature,” Wadsworth says. “Part of our spirit has left us. And that’s why we fight so hard to hold on to what’s left.”

    The data center boom in the desert
    In the high desert east of Reno, Nevada, construction crews are flattening the golden foothills of the Virginia Range, laying the foundations of a data center city. Google, Tract, Switch, EdgeCore, Novva, Vantage, and PowerHouse are all operating, building, or expanding huge facilities within the Tahoe Reno Industrial Center, a business park bigger than the city of Detroit.  This story is a part of MIT Technology Review’s series “Power Hungry: AI and our energy future,” on the energy demands and carbon costs of the artificial-intelligence revolution. Meanwhile, Microsoft acquired more than 225 acres of undeveloped property within the center and an even larger plot in nearby Silver Springs, Nevada. Apple is expanding its data center, located just across the Truckee River from the industrial park. OpenAI has said it’s considering building a data center in Nevada as well. The corporate race to amass computing resources to train and run artificial intelligence models and store information in the cloud has sparked a data center boom in the desert—just far enough away from Nevada’s communities to elude wide notice and, some fear, adequate scrutiny.  Switch, a data center company based in Las Vegas, says the full build-out of its campus at the Tahoe Reno Industrial Center could exceed seven million square feet.EMILY NAJERA The full scale and potential environmental impacts of the developments aren’t known, because the footprint, energy needs, and water requirements are often closely guarded corporate secrets. Most of the companies didn’t respond to inquiries from MIT Technology Review, or declined to provide additional information about the projects.  But there’s “a whole lot of construction going on,” says Kris Thompson, who served as the longtime project manager for the industrial center before stepping down late last year. “The last number I heard was 13 million square feet under construction right now, which is massive.” Indeed, it’s the equivalent of almost five Empire State Buildings laid out flat. In addition, public filings from NV Energy, the state’s near-monopoly utility, reveal that a dozen data-center projects, mostly in this area, have requested nearly six gigawatts of electricity capacity within the next decade.  That would make the greater Reno area—the biggest little city in the world—one of the largest data-center markets around the globe. It would also require expanding the state’s power sector by about 40%, all for a single industry in an explosive growth stage that may, or may not, prove sustainable. The energy needs, in turn, suggest those projects could consume billions of gallons of water per year, according to an analysis conducted for this story.  Construction crews are busy building data centers throughout the Tahoe Reno Industrial Center.EMILY NAJERA The build-out of a dense cluster of energy and water-hungry data centers in a small stretch of the nation’s driest state, where climate change is driving up temperatures faster than anywhere else in the country, has begun to raise alarms among water experts, environmental groups, and residents. That includes members of the Pyramid Lake Paiute Tribe, whose namesake water body lies within their reservation and marks the end point of the Truckee River, the region’s main source of water. Much of Nevada has suffered through severe drought conditions for years, farmers and communities are drawing down many of the state’s groundwater reservoirs faster than they can be refilled, and global warming is sucking more and more moisture out of the region’s streams, shrubs, and soils. “Telling entities that they can come in and stick more straws in the ground for data centers is raising a lot of questions about sound management,” says Kyle Roerink, executive director of the Great Basin Water Network, a nonprofit that works to protect water resources throughout Nevada and Utah.  “We just don’t want to be in a situation where the tail is wagging the dog,” he later added, “where this demand for data centers is driving water policy.” Luring data centers In the late 1850s, the mountains southeast of Reno began enticing prospectors from across the country, who hoped to strike silver or gold in the famed Comstock Lode. But Storey County had few residents or economic prospects by the late 1990s, around the time when Don Roger Norman, a media-shy real estate speculator, spotted a new opportunity in the sagebrush-covered hills.  He began buying up tens of thousands of acres of land for tens of millions of dollars and lining up development approvals to lure industrial projects to what became the Tahoe Reno Industrial Center. His partners included Lance Gilman, a cowboy-hat-wearing real estate broker, who later bought the nearby Mustang Ranch brothel and won a seat as a county commissioner. In 1999, the county passed an ordinance that preapproves companies to develop most types of commercial and industrial projects across the business park, cutting months to years off the development process. That helped cinch deals with a flock of tenants looking to build big projects fast, including Walmart, Tesla, and Redwood Materials. Now the promise of fast permits is helping to draw data centers by the gigawatt. On a clear, cool January afternoon, Brian Armon, a commercial real estate broker who leads the industrial practices group at NAI Alliance, takes me on a tour of the projects around the region, which mostly entails driving around the business center. Lance Gilman, a local real estate broker, helped to develop the Tahoe Reno Industrial Center and land some of its largest tenants.GREGG SEGAL After pulling off Interstate 80 onto USA Parkway, he points out the cranes, earthmovers, and riprap foundations, where a variety of data centers are under construction. Deeper into the industrial park, Armon pulls up near Switch’s long, low, arched-roof facility, which sits on a terrace above cement walls and security gates. The Las Vegas–based company says the first phase of its data center campus encompasses more than a million square feet, and that the full build-out will cover seven times that space.  Over the next hill, we turn around in Google’s parking lot. Cranes, tents, framing, and construction equipment extend behind the company’s existing data center, filling much of the 1,210-acre lot that the search engine giant acquired in 2017. Last August, during an event at the University of Nevada, Reno, the company announced it would spend million to expand the data center campus along with another one in Las Vegas. Thompson says that the development company, Tahoe Reno Industrial LLC, has now sold off every parcel of developable land within the park. When I ask Armon what’s attracting all the data centers here, he starts with the fast approvals but cites a list of other lures as well: The inexpensive land. NV Energy’s willingness to strike deals to supply relatively low-cost electricity. Cool nighttime and winter temperatures, as far as American deserts go, which reduce the energy and water needs. The proximity to tech hubs such as Silicon Valley, which cuts latency for applications in which milliseconds matter. And the lack of natural disasters that could shut down the facilities, at least for the most part. “We are high in seismic activity,” he says. “But everything else is good. We’re not going to have a tornado or flood or a devastating wildfire.” Then there’s the generous tax policies.In 2023, Novva, a Utah-based data center company, announced plans to build a 300,000-square-foot facility within the industrial business park. Nevada doesn’t charge corporate income tax, and it has also enacted deep tax cuts specifically for data centers that set up shop in the state. That includes abatements of up to 75% on property tax for a decade or two—and nearly as much of a bargain on the sales and use taxes applied to equipment purchased for the facilities. Data centers don’t require many permanent workers to run the operations, but the projects have created thousands of construction jobs. They’re also helping to diversify the region’s economy beyond casinos and generating tax windfalls for the state, counties, and cities, says Jeff Sutich, executive director of the Northern Nevada Development Authority. Indeed, just three data-center projects, developed by Apple, Google, and Vantage, will produce nearly half a billion dollars in tax revenue for Nevada, even with those generous abatements, according to the Nevada Governor’s Office of Economic Development. The question is whether the benefits of data centers are worth the tradeoffs for Nevadans, given the public health costs, greenhouse-gas emissions, energy demands, and water strains. The rain shadow The Sierra Nevada’s granite peaks trace the eastern edge of California, forcing Pacific Ocean winds to rise and cool. That converts water vapor in the air into the rain and snow that fill the range’s tributaries, rivers, and lakes.  But the same meteorological phenomenon casts a rain shadow over much of neighboring Nevada, forming an arid expanse known as the Great Basin Desert. The state receives about 10 inches of precipitation a year, about a third of the national average. The Truckee River draws from the melting Sierra snowpack at the edge of Lake Tahoe, cascades down the range, and snakes through the flatlands of Reno and Sparks. It forks at the Derby Dam, a Reclamation Act project a few miles from the Tahoe Reno Industrial Center, which diverts water to a farming region further east while allowing the rest to continue north toward Pyramid Lake.  Along the way, an engineered system of reservoirs, canals, and treatment plants divert, store, and release water from the river, supplying businesses, cities, towns, and native tribes across the region. But Nevada’s population and economy are expanding, creating more demands on these resources even as they become more constrained.  The Truckee River, which originates at Lake Tahoe and terminates at Pyramid Lake, is the major water source for cities, towns, and farms across northwestern Nevada.EMILY NAJERA Throughout much of the 2020s the state has suffered through one of the hottest and most widespread droughts on record, extending two decades of abnormally dry conditions across the American West. Some scientists fear it may constitute an emerging megadrought.  About 50% of Nevada currently faces moderate to exceptional drought conditions. In addition, more than half of the state’s hundreds of groundwater basins are already “over-appropriated,” meaning the water rights on paper exceed the levels believed to be underground.  It’s not clear if climate change will increase or decrease the state’s rainfall levels, on balance. But precipitation patterns are expected to become more erratic, whiplashing between short periods of intense rainfall and more-frequent, extended, or severe droughts.  In addition, more precipitation will fall as rain rather than snow, shortening the Sierra snow season by weeks to months over the coming decades.  “In the extreme case, at the end of the century, that’s pretty much all of winter,” says Sean McKenna, executive director of hydrologic sciences at the Desert Research Institute, a research division of the Nevada System of Higher Education. That loss will undermine an essential function of the Sierra snowpack: reliably delivering water to farmers and cities when it’s most needed in the spring and summer, across both Nevada and California.  These shifting conditions will require the region to develop better ways to store, preserve, and recycle the water it does get, McKenna says. Northern Nevada’s cities, towns, and agencies will also need to carefully evaluate and plan for the collective impacts of continuing growth and development on the interconnected water system, particularly when it comes to water-hungry projects like data centers, he adds. “We can’t consider each of these as a one-off, without considering that there may be tens or dozens of these in the next 15 years,” McKenna says.Thirsty data centers Data centers suck up water in two main ways. As giant rooms of server racks process information and consume energy, they generate heat that must be shunted away to prevent malfunctions and damage to the equipment. The processing units optimized for training and running AI models often draw more electricity and, in turn, produce more heat. To keep things cool, more and more data centers have turned to liquid cooling systems that don’t need as much electricity as fan cooling or air-conditioning. These often rely on water to absorb heat and transfer it to outdoor cooling towers, where much of the moisture evaporates. Microsoft’s US data centers, for instance, could have directly evaporated nearly 185,000 gallons of “clean freshwater” in the course of training OpenAI’s GPT-3 large language model, according to a 2023 preprint study led by researchers at the University of California, Riverside.What’s less appreciated, however, is that the larger data-center drain on water generally occurs indirectly, at the power plants generating extra electricity for the turbocharged AI sector. These facilities, in turn, require more water to cool down equipment, among other purposes. You have to add up both uses “to reflect the true water cost of data centers,” says Shaolei Ren, an associate professor of electrical and computer engineering at UC Riverside and coauthor of the study. Ren estimates that the 12 data-center projects listed in NV Energy’s report would directly consume between 860 million gallons and 5.7 billion gallons a year, based on the requested electricity capacity.The indirect water drain associated with electricity generation for those operations could add up to 15.5 billion gallons, based on the average consumption of the regional grid. The exact water figures would depend on shifting climate conditions, the type of cooling systems each data center uses, and the mix of power sources that supply the facilities. Solar power, which provides roughly a quarter of Nevada’s power, requires relatively little water to operate, for instance. But natural-gas plants, which generate about 56%, withdraw 2,803 gallons per megawatt-hour on average, according to the Energy Information Administration.  Geothermal plants, which produce about 10% of the state’s electricity by cycling water through hot rocks, generally consume less water than fossil fuel plants do but often require more water than other renewables, according to some research.  But here too, the water usage varies depending on the type of geothermal plant in question. Google has lined up several deals to partially power its data centers through Fervo Energy, which has helped to commercialize an emerging approach that injects water under high pressure to fracture rock and form wells deep below the surface.  The company stresses that it doesn’t evaporate water for cooling and that it relies on brackish groundwater, not fresh water, to develop and run its plants. In a recent post, Fervo noted that its facilities consume significantly less water per megawatt-hour than coal, nuclear, or natural-gas plants do. Part of NV Energy’s proposed plan to meet growing electricity demands in Nevada includes developing several natural-gas peaking units, adding more than one gigawatt of solar power and installing another gigawatt of battery storage. It's also forging ahead with a more than billion transmission project. But the company didn’t respond to questions concerning how it will supply all of the gigawatts of additional electricity requested by data centers, if the construction of those power plants will increase consumer rates, or how much water those facilities are expected to consume. NV Energy operates a transmission line, substation, and power plant in or around the Tahoe Reno Industrial Center.EMILY NAJERA “NV Energy teams work diligently on our long-term planning to make investments in our infrastructure to serve new customers and the continued growth in the state without putting existing customers at risk,” the company said in a statement. An added challenge is that data centers need to run around the clock. That will often compel utilities to develop new electricity-generating sources that can run nonstop as well, as natural-gas, geothermal, or nuclear plants do, says Emily Grubert, an associate professor of sustainable energy policy at the University of Notre Dame, who has studied the relative water consumption of electricity sources.  “You end up with the water-intensive resources looking more important,” she adds. Even if NV Energy and the companies developing data centers do strive to power them through sources with relatively low water needs, “we only have so much ability to add six gigawatts to Nevada’s grid,” Grubert explains. “What you do will never be system-neutral, because it’s such a big number.” Securing supplies On a mid-February morning, I meet TRI’s Thompson and Don Gilman, Lance Gilman’s son, at the Storey County offices, located within the industrial center.  “I’m just a country boy who sells dirt,” Gilman, also a real estate broker, says by way of introduction.  We climb into his large SUV and drive to a reservoir in the heart of the industrial park, filled nearly to the lip.  Thompson explains that much of the water comes from an on-site treatment facility that filters waste fluids from companies in the park. In addition, tens of millions of gallons of treated effluent will also likely flow into the tank this year from the Truckee Meadows Water Authority Reclamation Facility, near the border of Reno and Sparks. That’s thanks to a 16-mile pipeline that the developers, the water authority, several tenants, and various local cities and agencies partnered to build, through a project that began in 2021. “Our general improvement district is furnishing that water to tech companies here in the park as we speak,” Thompson says. “That helps preserve the precious groundwater, so that is an environmental feather in the cap for these data centers. They are focused on environmental excellence.” The reservoir within the industrial business park provides water to data centers and other tenants.EMILY NAJERA But data centers often need drinking-quality water—not wastewater merely treated to irrigation standards—for evaporative cooling, “to avoid pipe clogs and/or bacterial growth,” the UC Riverside study notes. For instance, Google says its data centers withdrew about 7.7 billion gallons of water in 2023, and nearly 6 billion of those gallons were potable.  Tenants in the industrial park can potentially obtain access to water from the ground and the Truckee River, as well. From early on, the master developers worked hard to secure permits to water sources, since they are nearly as precious as development entitlements to companies hoping to build projects in the desert. Initially, the development company controlled a private business, the TRI Water and Sewer Company, that provided those services to the business park’s tenants, according to public documents. The company set up wells, a water tank, distribution lines, and a sewer disposal system.  But in 2000, the board of county commissioners established a general improvement district, a legal mechanism for providing municipal services in certain parts of the state, to manage electricity and then water within the center. It, in turn, hired TRI Water and Sewer as the operating company. As of its 2020 service plan, the general improvement district held permits for nearly 5,300 acre-feet of groundwater, “which can be pumped from well fields within the service area and used for new growth as it occurs.” The document lists another 2,000 acre-feet per year available from the on-site treatment facility, 1,000 from the Truckee River, and 4,000 more from the effluent pipeline.  Those figures haven’t budged much since, according to Shari Whalen, general manager of the TRI General Improvement District. All told, they add up to more than 4 billion gallons of water per year for all the needs of the industrial park and the tenants there, data centers and otherwise. Whalen says that the amount and quality of water required for any given data center depends on its design, and that those matters are worked out on a case-by-case basis.  When asked if the general improvement district is confident that it has adequate water resources to supply the needs of all the data centers under development, as well as other tenants at the industrial center, she says: “They can’t just show up and build unless they have water resources designated for their projects. We wouldn’t approve a project if it didn’t have those water resources.” Water As the region’s water sources have grown more constrained, lining up supplies has become an increasingly high-stakes and controversial business. More than a century ago, the US federal government filed a lawsuit against an assortment of parties pulling water from the Truckee River. The suit would eventually establish that the Pyramid Lake Paiute Tribe’s legal rights to water for irrigation superseded other claims. But the tribe has been fighting to protect those rights and increase flows from the river ever since, arguing that increasing strains on the watershed from upstream cities and businesses threaten to draw away water reserved for reservation farming, decrease lake levels, and harm native fish. The Pyramid Lake Paiute Tribe considers the water body and its fish, including the endangered cui-ui and threatened Lahontan cutthroat trout, to be essential parts of its culture, identity, and way of life. The tribe was originally named Cui-ui Ticutta, which translates to cui-ui eaters. The lake continues to provide sustenance as well as business for the tribe and its members, a number of whom operate boat charters and fishing guide services. “It’s completely tied into us as a people,” says Steven Wadsworth, chairman of the Pyramid Lake Paiute Tribe. “That is what has sustained us all this time,” he adds. “It’s just who we are. It’s part of our spiritual well-being.” Steven Wadsworth, chairman of the Pyramid Lake Paiute Tribe, fears that data centers will divert water that would otherwise reach the tribe’s namesake lake.EMILY NAJERA In recent decades, the tribe has sued the Nevada State Engineer, Washoe County, the federal government, and others for overallocating water rights and endangering the lake’s fish. It also protested the TRI General Improvement District’s applications to draw thousands of additional acre‑feet of groundwater from a basin near the business park. In 2019, the State Engineer’s office rejected those requests, concluding that the basin was already fully appropriated.  More recently, the tribe took issue with the plan to build the pipeline and divert effluent that would have flown into the Truckee, securing an agreement that required the Truckee Meadows Water Authority and other parties to add back several thousand acre‑feet of water to the river.  Whalen says she’s sensitive to Wadsworth’s concerns. But she says that the pipeline promises to keep a growing amount of treated wastewater out of the river, where it could otherwise contribute to rising salt levels in the lake. “I think that the pipeline fromto our system is good for water quality in the river,” she says. “I understand philosophically the concerns about data centers, but the general improvement district is dedicated to working with everyone on the river for regional water-resource planning—and the tribe is no exception.” Water efficiency  In an email, Thompson added that he has “great respect and admiration,” for the tribe and has visited the reservation several times in an effort to help bring industrial or commercial development there. He stressed that all of the business park’s groundwater was “validated by the State Water Engineer,” and that the rights to surface water and effluent were purchased “for fair market value.”During the earlier interview at the industrial center, he and Gilman had both expressed confidence that tenants in the park have adequate water supplies, and that the businesses won’t draw water away from other areas.  “We’re in our own aquifer, our own water basin here,” Thompson said. “You put a straw in the ground here, you’re not going to pull water from Fernley or from Reno or from Silver Springs.” Gilman also stressed that data-center companies have gotten more water efficient in recent years, echoing a point others made as well. “With the newer technology, it’s not much of a worry,” says Sutich, of the Northern Nevada Development Authority. “The technology has come a long way in the last 10 years, which is really giving these guys the opportunity to be good stewards of water usage.” An aerial view of the cooling tower fans at Google’s data center in the Tahoe Reno Industrial Center.GOOGLE Indeed, Google’s existing Storey County facility is air-cooled, according to the company’s latest environmental report. The data center withdrew 1.9 million gallons in 2023 but only consumed 200,000 gallons. The rest cycles back into the water system. Google said all the data centers under construction on its campus will also “utilize air-cooling technology.” The company didn’t respond to a question about the scale of its planned expansion in the Tahoe Reno Industrial Center, and referred a question about indirect water consumption to NV Energy. The search giant has stressed that it strives to be water efficient across all of its data centers, and decides whether to use air or liquid cooling based on local supply and projected demand, among other variables. Four years ago, the company set a goal of replenishing more water than it consumes by 2030. Locally, it also committed to provide half a million dollars to the National Forest Foundation to improve the Truckee River watershed and reduce wildfire risks.  Microsoft clearly suggested in earlier news reports that the Silver Springs land it purchased around the end of 2022 would be used for a data center. NAI Alliance’s market real estate report identifies that lot, as well as the parcel Microsoft purchased within the Tahoe Reno Industrial Center, as data center sites. But the company now declines to specify what it intends to build in the region.  “While the land purchase is public knowledge, we have not disclosed specific detailsour plans for the land or potential development timelines,” wrote Donna Whitehead, a Microsoft spokesperson, in an email.  Workers have begun grading land inside a fenced off lot within the Tahoe Reno Industrial Center.EMILY NAJERA Microsoft has also scaled down its global data-center ambitions, backing away from several projects in recent months amid shifting economic conditions, according to various reports. Whatever it ultimately does or doesn’t build, the company stresses that it has made strides to reduce water consumption in its facilities. Late last year, the company announced that it’s using “chip-level cooling solutions” in data centers, which continually circulate water between the servers and chillers through a closed loop that the company claims doesn’t lose any water to evaporation. It says the design requires only a “nominal increase” in energy compared to its data centers that rely on evaporative water cooling. Others seem to be taking a similar approach. EdgeCore also said its 900,000-square-foot data center at the Tahoe Reno Industrial Center will rely on an “air-cooled closed-loop chiller” that doesn’t require water evaporation for cooling.  But some of the companies seem to have taken steps to ensure access to significant amounts of water. Switch, for instance, took a lead role in developing the effluent pipeline. In addition, Tract, which develops campuses on which third-party data centers can build their own facilities, has said it lined up more than 1,100 acre-feet of water rights, the equivalent of nearly 360 million gallons a year.  Apple, Novva, Switch, Tract, and Vantage didn’t respond to inquiries from MIT Technology Review.  Coming conflicts  The suggestion that companies aren’t straining water supplies when they adopt air cooling is, in many cases, akin to saying they’re not responsible for the greenhouse gas produced through their power use simply because it occurs outside of their facilities. In fact, the additional water used at a power plant to meet the increased electricity needs of air cooling may exceed any gains at the data center, Ren, of UC Riverside, says. “That’s actually very likely, because it uses a lot more energy,” he adds. That means that some of the companies developing data centers in and around Storey County may simply hand off their water challenges to other parts of Nevada or neighboring states across the drying American West, depending on where and how the power is generated, Ren says.  Google has said its air-cooled facilities require about 10% more electricity, and its environmental report notes that the Storey County facility is one of its two least-energy-efficient data centers.  Pipes running along Google’s data center campus help the search company cool its servers.GOOGLE Some fear there’s also a growing mismatch between what Nevada’s water permits allow, what’s actually in the ground, and what nature will provide as climate conditions shift. Notably, the groundwater committed to all parties from the Tracy Segment basin—a long-fought-over resource that partially supplies the TRI General Improvement District—already exceeds the “perennial yield.” That refers to the maximum amount that can be drawn out every year without depleting the reservoir over the long term. “If pumping does ultimately exceed the available supply, that means there will be conflict among users,” Roerink, of the Great Basin Water Network, said in an email. “So I have to wonder: Who could be suing whom? Who could be buying out whom? How will the tribe’s rights be defended?”The Truckee Meadows Water Authority, the community-owned utility that manages the water system for Reno and Sparks, said it is planning carefully for the future and remains confident there will be “sufficient resources for decades to come,” at least within its territory east of the industrial center. Storey County, the Truckee-Carson Irrigation District, and the State Engineer’s office didn’t respond to questions or accept interview requests.  Open for business As data center proposals have begun shifting into Northern Nevada’s cities, more local residents and organizations have begun to take notice and express concerns. The regional division of the Sierra Club, for instance, recently sought to overturn the approval of Reno’s first data center, about 20 miles west of the Tahoe Reno Industrial Center.  Olivia Tanager, director of the Sierra Club’s Toiyabe Chapter, says the environmental organization was shocked by the projected electricity demands from data centers highlighted in NV Energy’s filings. Nevada’s wild horses are a common sight along USA Parkway, the highway cutting through the industrial business park. EMILY NAJERA “We have increasing interest in understanding the impact that data centers will have to our climate goals, to our grid as a whole, and certainly to our water resources,” she says. “The demands are extraordinary, and we don’t have that amount of water to toy around with.” During a city hall hearing in January that stretched late into the evening, she and a line of residents raised concerns about the water, energy, climate, and employment impacts of AI data centers. At the end, though, the city council upheld the planning department’s approval of the project, on a 5-2 vote. “Welcome to Reno,” Kathleen Taylor, Reno’s vice mayor, said before casting her vote. “We’re open for business.” Where the river ends In late March, I walk alongside Chairman Wadsworth, of the Pyramid Lake Paiute Tribe, on the shores of Pyramid Lake, watching a row of fly-fishers in waders cast their lines into the cold waters.  The lake is the largest remnant of Lake Lahontan, an Ice Age inland sea that once stretched across western Nevada and would have submerged present-day Reno. But as the climate warmed, the lapping waters retreated, etching erosional terraces into the mountainsides and exposing tufa deposits around the lake, large formations of porous rock made of calcium-carbonate. That includes the pyramid-shaped island on the eastern shore that inspired the lake’s name. A lone angler stands along the shores of Pyramid Lake. In the decades after the US Reclamation Service completed the Derby Dam in 1905, Pyramid Lake declined another 80 feet and nearby Winnemucca Lake dried up entirely. “We know what happens when water use goes unchecked,” says Wadsworth, gesturing eastward toward the range across the lake, where Winnemucca once filled the next basin over. “Because all we have to do is look over there and see a dry, barren lake bed that used to be full.”In an earlier interview, Wadsworth acknowledged that the world needs data centers. But he argued they should be spread out across the country, not densely clustered in the middle of the Nevada desert.Given the fierce competition for resources up to now, he can’t imagine how there could be enough water to meet the demands of data centers, expanding cities, and other growing businesses without straining the limited local supplies that should, by his accounting, flow to Pyramid Lake. He fears these growing pressures will force the tribe to wage new legal battles to protect their rights and preserve the lake, extending what he refers to as “a century of water wars.” “We have seen the devastating effects of what happens when you mess with Mother Nature,” Wadsworth says. “Part of our spirit has left us. And that’s why we fight so hard to hold on to what’s left.” #data #center #boom #desert

    The data center boom in the desert
    In the high desert east of Reno, Nevada, construction crews are flattening the golden foothills of the Virginia Range, laying the foundations of a data center city. Google, Tract, Switch, EdgeCore, Novva, Vantage, and PowerHouse are all operating, building, or expanding huge facilities within the Tahoe Reno Industrial Center, a business park bigger than the city of Detroit.  This story is a part of MIT Technology Review’s series “Power Hungry: AI and our energy future,” on the energy demands and carbon costs of the artificial-intelligence revolution. Meanwhile, Microsoft acquired more than 225 acres of undeveloped property within the center and an even larger plot in nearby Silver Springs, Nevada. Apple is expanding its data center, located just across the Truckee River from the industrial park. OpenAI has said it’s considering building a data center in Nevada as well. The corporate race to amass computing resources to train and run artificial intelligence models and store information in the cloud has sparked a data center boom in the desert—just far enough away from Nevada’s communities to elude wide notice and, some fear, adequate scrutiny.  Switch, a data center company based in Las Vegas, says the full build-out of its campus at the Tahoe Reno Industrial Center could exceed seven million square feet.EMILY NAJERA The full scale and potential environmental impacts of the developments aren’t known, because the footprint, energy needs, and water requirements are often closely guarded corporate secrets. Most of the companies didn’t respond to inquiries from MIT Technology Review, or declined to provide additional information about the projects.  But there’s “a whole lot of construction going on,” says Kris Thompson, who served as the longtime project manager for the industrial center before stepping down late last year. “The last number I heard was 13 million square feet under construction right now, which is massive.” Indeed, it’s the equivalent of almost five Empire State Buildings laid out flat. In addition, public filings from NV Energy, the state’s near-monopoly utility, reveal that a dozen data-center projects, mostly in this area, have requested nearly six gigawatts of electricity capacity within the next decade.  That would make the greater Reno area—the biggest little city in the world—one of the largest data-center markets around the globe. It would also require expanding the state’s power sector by about 40%, all for a single industry in an explosive growth stage that may, or may not, prove sustainable. The energy needs, in turn, suggest those projects could consume billions of gallons of water per year, according to an analysis conducted for this story.  Construction crews are busy building data centers throughout the Tahoe Reno Industrial Center.EMILY NAJERA The build-out of a dense cluster of energy and water-hungry data centers in a small stretch of the nation’s driest state, where climate change is driving up temperatures faster than anywhere else in the country, has begun to raise alarms among water experts, environmental groups, and residents. That includes members of the Pyramid Lake Paiute Tribe, whose namesake water body lies within their reservation and marks the end point of the Truckee River, the region’s main source of water. Much of Nevada has suffered through severe drought conditions for years, farmers and communities are drawing down many of the state’s groundwater reservoirs faster than they can be refilled, and global warming is sucking more and more moisture out of the region’s streams, shrubs, and soils. “Telling entities that they can come in and stick more straws in the ground for data centers is raising a lot of questions about sound management,” says Kyle Roerink, executive director of the Great Basin Water Network, a nonprofit that works to protect water resources throughout Nevada and Utah.  “We just don’t want to be in a situation where the tail is wagging the dog,” he later added, “where this demand for data centers is driving water policy.” Luring data centers In the late 1850s, the mountains southeast of Reno began enticing prospectors from across the country, who hoped to strike silver or gold in the famed Comstock Lode. But Storey County had few residents or economic prospects by the late 1990s, around the time when Don Roger Norman, a media-shy real estate speculator, spotted a new opportunity in the sagebrush-covered hills.  He began buying up tens of thousands of acres of land for tens of millions of dollars and lining up development approvals to lure industrial projects to what became the Tahoe Reno Industrial Center. His partners included Lance Gilman, a cowboy-hat-wearing real estate broker, who later bought the nearby Mustang Ranch brothel and won a seat as a county commissioner. In 1999, the county passed an ordinance that preapproves companies to develop most types of commercial and industrial projects across the business park, cutting months to years off the development process. That helped cinch deals with a flock of tenants looking to build big projects fast, including Walmart, Tesla, and Redwood Materials. Now the promise of fast permits is helping to draw data centers by the gigawatt. On a clear, cool January afternoon, Brian Armon, a commercial real estate broker who leads the industrial practices group at NAI Alliance, takes me on a tour of the projects around the region, which mostly entails driving around the business center. Lance Gilman, a local real estate broker, helped to develop the Tahoe Reno Industrial Center and land some of its largest tenants.GREGG SEGAL After pulling off Interstate 80 onto USA Parkway, he points out the cranes, earthmovers, and riprap foundations, where a variety of data centers are under construction. Deeper into the industrial park, Armon pulls up near Switch’s long, low, arched-roof facility, which sits on a terrace above cement walls and security gates. The Las Vegas–based company says the first phase of its data center campus encompasses more than a million square feet, and that the full build-out will cover seven times that space.  Over the next hill, we turn around in Google’s parking lot. Cranes, tents, framing, and construction equipment extend behind the company’s existing data center, filling much of the 1,210-acre lot that the search engine giant acquired in 2017. Last August, during an event at the University of Nevada, Reno, the company announced it would spend $400 million to expand the data center campus along with another one in Las Vegas. Thompson says that the development company, Tahoe Reno Industrial LLC, has now sold off every parcel of developable land within the park (although several lots are available for resale following the failed gamble of one crypto tenant). When I ask Armon what’s attracting all the data centers here, he starts with the fast approvals but cites a list of other lures as well: The inexpensive land. NV Energy’s willingness to strike deals to supply relatively low-cost electricity. Cool nighttime and winter temperatures, as far as American deserts go, which reduce the energy and water needs. The proximity to tech hubs such as Silicon Valley, which cuts latency for applications in which milliseconds matter. And the lack of natural disasters that could shut down the facilities, at least for the most part. “We are high in seismic activity,” he says. “But everything else is good. We’re not going to have a tornado or flood or a devastating wildfire.” Then there’s the generous tax policies.In 2023, Novva, a Utah-based data center company, announced plans to build a 300,000-square-foot facility within the industrial business park. Nevada doesn’t charge corporate income tax, and it has also enacted deep tax cuts specifically for data centers that set up shop in the state. That includes abatements of up to 75% on property tax for a decade or two—and nearly as much of a bargain on the sales and use taxes applied to equipment purchased for the facilities. Data centers don’t require many permanent workers to run the operations, but the projects have created thousands of construction jobs. They’re also helping to diversify the region’s economy beyond casinos and generating tax windfalls for the state, counties, and cities, says Jeff Sutich, executive director of the Northern Nevada Development Authority. Indeed, just three data-center projects, developed by Apple, Google, and Vantage, will produce nearly half a billion dollars in tax revenue for Nevada, even with those generous abatements, according to the Nevada Governor’s Office of Economic Development. The question is whether the benefits of data centers are worth the tradeoffs for Nevadans, given the public health costs, greenhouse-gas emissions, energy demands, and water strains. The rain shadow The Sierra Nevada’s granite peaks trace the eastern edge of California, forcing Pacific Ocean winds to rise and cool. That converts water vapor in the air into the rain and snow that fill the range’s tributaries, rivers, and lakes.  But the same meteorological phenomenon casts a rain shadow over much of neighboring Nevada, forming an arid expanse known as the Great Basin Desert. The state receives about 10 inches of precipitation a year, about a third of the national average. The Truckee River draws from the melting Sierra snowpack at the edge of Lake Tahoe, cascades down the range, and snakes through the flatlands of Reno and Sparks. It forks at the Derby Dam, a Reclamation Act project a few miles from the Tahoe Reno Industrial Center, which diverts water to a farming region further east while allowing the rest to continue north toward Pyramid Lake.  Along the way, an engineered system of reservoirs, canals, and treatment plants divert, store, and release water from the river, supplying businesses, cities, towns, and native tribes across the region. But Nevada’s population and economy are expanding, creating more demands on these resources even as they become more constrained.  The Truckee River, which originates at Lake Tahoe and terminates at Pyramid Lake, is the major water source for cities, towns, and farms across northwestern Nevada.EMILY NAJERA Throughout much of the 2020s the state has suffered through one of the hottest and most widespread droughts on record, extending two decades of abnormally dry conditions across the American West. Some scientists fear it may constitute an emerging megadrought.  About 50% of Nevada currently faces moderate to exceptional drought conditions. In addition, more than half of the state’s hundreds of groundwater basins are already “over-appropriated,” meaning the water rights on paper exceed the levels believed to be underground.  It’s not clear if climate change will increase or decrease the state’s rainfall levels, on balance. But precipitation patterns are expected to become more erratic, whiplashing between short periods of intense rainfall and more-frequent, extended, or severe droughts.  In addition, more precipitation will fall as rain rather than snow, shortening the Sierra snow season by weeks to months over the coming decades.  “In the extreme case, at the end of the century, that’s pretty much all of winter,” says Sean McKenna, executive director of hydrologic sciences at the Desert Research Institute, a research division of the Nevada System of Higher Education. That loss will undermine an essential function of the Sierra snowpack: reliably delivering water to farmers and cities when it’s most needed in the spring and summer, across both Nevada and California.  These shifting conditions will require the region to develop better ways to store, preserve, and recycle the water it does get, McKenna says. Northern Nevada’s cities, towns, and agencies will also need to carefully evaluate and plan for the collective impacts of continuing growth and development on the interconnected water system, particularly when it comes to water-hungry projects like data centers, he adds. “We can’t consider each of these as a one-off, without considering that there may be tens or dozens of these in the next 15 years,” McKenna says.Thirsty data centers Data centers suck up water in two main ways. As giant rooms of server racks process information and consume energy, they generate heat that must be shunted away to prevent malfunctions and damage to the equipment. The processing units optimized for training and running AI models often draw more electricity and, in turn, produce more heat. To keep things cool, more and more data centers have turned to liquid cooling systems that don’t need as much electricity as fan cooling or air-conditioning. These often rely on water to absorb heat and transfer it to outdoor cooling towers, where much of the moisture evaporates. Microsoft’s US data centers, for instance, could have directly evaporated nearly 185,000 gallons of “clean freshwater” in the course of training OpenAI’s GPT-3 large language model, according to a 2023 preprint study led by researchers at the University of California, Riverside. (The research has since been peer-reviewed and is awaiting publication.) What’s less appreciated, however, is that the larger data-center drain on water generally occurs indirectly, at the power plants generating extra electricity for the turbocharged AI sector. These facilities, in turn, require more water to cool down equipment, among other purposes. You have to add up both uses “to reflect the true water cost of data centers,” says Shaolei Ren, an associate professor of electrical and computer engineering at UC Riverside and coauthor of the study. Ren estimates that the 12 data-center projects listed in NV Energy’s report would directly consume between 860 million gallons and 5.7 billion gallons a year, based on the requested electricity capacity. (“Consumed” here means the water is evaporated, not merely withdrawn and returned to the engineered water system.) The indirect water drain associated with electricity generation for those operations could add up to 15.5 billion gallons, based on the average consumption of the regional grid. The exact water figures would depend on shifting climate conditions, the type of cooling systems each data center uses, and the mix of power sources that supply the facilities. Solar power, which provides roughly a quarter of Nevada’s power, requires relatively little water to operate, for instance. But natural-gas plants, which generate about 56%, withdraw 2,803 gallons per megawatt-hour on average, according to the Energy Information Administration.  Geothermal plants, which produce about 10% of the state’s electricity by cycling water through hot rocks, generally consume less water than fossil fuel plants do but often require more water than other renewables, according to some research.  But here too, the water usage varies depending on the type of geothermal plant in question. Google has lined up several deals to partially power its data centers through Fervo Energy, which has helped to commercialize an emerging approach that injects water under high pressure to fracture rock and form wells deep below the surface.  The company stresses that it doesn’t evaporate water for cooling and that it relies on brackish groundwater, not fresh water, to develop and run its plants. In a recent post, Fervo noted that its facilities consume significantly less water per megawatt-hour than coal, nuclear, or natural-gas plants do. Part of NV Energy’s proposed plan to meet growing electricity demands in Nevada includes developing several natural-gas peaking units, adding more than one gigawatt of solar power and installing another gigawatt of battery storage. It's also forging ahead with a more than $4 billion transmission project. But the company didn’t respond to questions concerning how it will supply all of the gigawatts of additional electricity requested by data centers, if the construction of those power plants will increase consumer rates, or how much water those facilities are expected to consume. NV Energy operates a transmission line, substation, and power plant in or around the Tahoe Reno Industrial Center.EMILY NAJERA “NV Energy teams work diligently on our long-term planning to make investments in our infrastructure to serve new customers and the continued growth in the state without putting existing customers at risk,” the company said in a statement. An added challenge is that data centers need to run around the clock. That will often compel utilities to develop new electricity-generating sources that can run nonstop as well, as natural-gas, geothermal, or nuclear plants do, says Emily Grubert, an associate professor of sustainable energy policy at the University of Notre Dame, who has studied the relative water consumption of electricity sources.  “You end up with the water-intensive resources looking more important,” she adds. Even if NV Energy and the companies developing data centers do strive to power them through sources with relatively low water needs, “we only have so much ability to add six gigawatts to Nevada’s grid,” Grubert explains. “What you do will never be system-neutral, because it’s such a big number.” Securing supplies On a mid-February morning, I meet TRI’s Thompson and Don Gilman, Lance Gilman’s son, at the Storey County offices, located within the industrial center.  “I’m just a country boy who sells dirt,” Gilman, also a real estate broker, says by way of introduction.  We climb into his large SUV and drive to a reservoir in the heart of the industrial park, filled nearly to the lip.  Thompson explains that much of the water comes from an on-site treatment facility that filters waste fluids from companies in the park. In addition, tens of millions of gallons of treated effluent will also likely flow into the tank this year from the Truckee Meadows Water Authority Reclamation Facility, near the border of Reno and Sparks. That’s thanks to a 16-mile pipeline that the developers, the water authority, several tenants, and various local cities and agencies partnered to build, through a project that began in 2021. “Our general improvement district is furnishing that water to tech companies here in the park as we speak,” Thompson says. “That helps preserve the precious groundwater, so that is an environmental feather in the cap for these data centers. They are focused on environmental excellence.” The reservoir within the industrial business park provides water to data centers and other tenants.EMILY NAJERA But data centers often need drinking-quality water—not wastewater merely treated to irrigation standards—for evaporative cooling, “to avoid pipe clogs and/or bacterial growth,” the UC Riverside study notes. For instance, Google says its data centers withdrew about 7.7 billion gallons of water in 2023, and nearly 6 billion of those gallons were potable.  Tenants in the industrial park can potentially obtain access to water from the ground and the Truckee River, as well. From early on, the master developers worked hard to secure permits to water sources, since they are nearly as precious as development entitlements to companies hoping to build projects in the desert. Initially, the development company controlled a private business, the TRI Water and Sewer Company, that provided those services to the business park’s tenants, according to public documents. The company set up wells, a water tank, distribution lines, and a sewer disposal system.  But in 2000, the board of county commissioners established a general improvement district, a legal mechanism for providing municipal services in certain parts of the state, to manage electricity and then water within the center. It, in turn, hired TRI Water and Sewer as the operating company. As of its 2020 service plan, the general improvement district held permits for nearly 5,300 acre-feet of groundwater, “which can be pumped from well fields within the service area and used for new growth as it occurs.” The document lists another 2,000 acre-feet per year available from the on-site treatment facility, 1,000 from the Truckee River, and 4,000 more from the effluent pipeline.  Those figures haven’t budged much since, according to Shari Whalen, general manager of the TRI General Improvement District. All told, they add up to more than 4 billion gallons of water per year for all the needs of the industrial park and the tenants there, data centers and otherwise. Whalen says that the amount and quality of water required for any given data center depends on its design, and that those matters are worked out on a case-by-case basis.  When asked if the general improvement district is confident that it has adequate water resources to supply the needs of all the data centers under development, as well as other tenants at the industrial center, she says: “They can’t just show up and build unless they have water resources designated for their projects. We wouldn’t approve a project if it didn’t have those water resources.” Water As the region’s water sources have grown more constrained, lining up supplies has become an increasingly high-stakes and controversial business. More than a century ago, the US federal government filed a lawsuit against an assortment of parties pulling water from the Truckee River. The suit would eventually establish that the Pyramid Lake Paiute Tribe’s legal rights to water for irrigation superseded other claims. But the tribe has been fighting to protect those rights and increase flows from the river ever since, arguing that increasing strains on the watershed from upstream cities and businesses threaten to draw away water reserved for reservation farming, decrease lake levels, and harm native fish. The Pyramid Lake Paiute Tribe considers the water body and its fish, including the endangered cui-ui and threatened Lahontan cutthroat trout, to be essential parts of its culture, identity, and way of life. The tribe was originally named Cui-ui Ticutta, which translates to cui-ui eaters. The lake continues to provide sustenance as well as business for the tribe and its members, a number of whom operate boat charters and fishing guide services. “It’s completely tied into us as a people,” says Steven Wadsworth, chairman of the Pyramid Lake Paiute Tribe. “That is what has sustained us all this time,” he adds. “It’s just who we are. It’s part of our spiritual well-being.” Steven Wadsworth, chairman of the Pyramid Lake Paiute Tribe, fears that data centers will divert water that would otherwise reach the tribe’s namesake lake.EMILY NAJERA In recent decades, the tribe has sued the Nevada State Engineer, Washoe County, the federal government, and others for overallocating water rights and endangering the lake’s fish. It also protested the TRI General Improvement District’s applications to draw thousands of additional acre‑feet of groundwater from a basin near the business park. In 2019, the State Engineer’s office rejected those requests, concluding that the basin was already fully appropriated.  More recently, the tribe took issue with the plan to build the pipeline and divert effluent that would have flown into the Truckee, securing an agreement that required the Truckee Meadows Water Authority and other parties to add back several thousand acre‑feet of water to the river.  Whalen says she’s sensitive to Wadsworth’s concerns. But she says that the pipeline promises to keep a growing amount of treated wastewater out of the river, where it could otherwise contribute to rising salt levels in the lake. “I think that the pipeline from [the Truckee Meadows Water Authority] to our system is good for water quality in the river,” she says. “I understand philosophically the concerns about data centers, but the general improvement district is dedicated to working with everyone on the river for regional water-resource planning—and the tribe is no exception.” Water efficiency  In an email, Thompson added that he has “great respect and admiration,” for the tribe and has visited the reservation several times in an effort to help bring industrial or commercial development there. He stressed that all of the business park’s groundwater was “validated by the State Water Engineer,” and that the rights to surface water and effluent were purchased “for fair market value.”During the earlier interview at the industrial center, he and Gilman had both expressed confidence that tenants in the park have adequate water supplies, and that the businesses won’t draw water away from other areas.  “We’re in our own aquifer, our own water basin here,” Thompson said. “You put a straw in the ground here, you’re not going to pull water from Fernley or from Reno or from Silver Springs.” Gilman also stressed that data-center companies have gotten more water efficient in recent years, echoing a point others made as well. “With the newer technology, it’s not much of a worry,” says Sutich, of the Northern Nevada Development Authority. “The technology has come a long way in the last 10 years, which is really giving these guys the opportunity to be good stewards of water usage.” An aerial view of the cooling tower fans at Google’s data center in the Tahoe Reno Industrial Center.GOOGLE Indeed, Google’s existing Storey County facility is air-cooled, according to the company’s latest environmental report. The data center withdrew 1.9 million gallons in 2023 but only consumed 200,000 gallons. The rest cycles back into the water system. Google said all the data centers under construction on its campus will also “utilize air-cooling technology.” The company didn’t respond to a question about the scale of its planned expansion in the Tahoe Reno Industrial Center, and referred a question about indirect water consumption to NV Energy. The search giant has stressed that it strives to be water efficient across all of its data centers, and decides whether to use air or liquid cooling based on local supply and projected demand, among other variables. Four years ago, the company set a goal of replenishing more water than it consumes by 2030. Locally, it also committed to provide half a million dollars to the National Forest Foundation to improve the Truckee River watershed and reduce wildfire risks.  Microsoft clearly suggested in earlier news reports that the Silver Springs land it purchased around the end of 2022 would be used for a data center. NAI Alliance’s market real estate report identifies that lot, as well as the parcel Microsoft purchased within the Tahoe Reno Industrial Center, as data center sites. But the company now declines to specify what it intends to build in the region.  “While the land purchase is public knowledge, we have not disclosed specific details [of] our plans for the land or potential development timelines,” wrote Donna Whitehead, a Microsoft spokesperson, in an email.  Workers have begun grading land inside a fenced off lot within the Tahoe Reno Industrial Center.EMILY NAJERA Microsoft has also scaled down its global data-center ambitions, backing away from several projects in recent months amid shifting economic conditions, according to various reports. Whatever it ultimately does or doesn’t build, the company stresses that it has made strides to reduce water consumption in its facilities. Late last year, the company announced that it’s using “chip-level cooling solutions” in data centers, which continually circulate water between the servers and chillers through a closed loop that the company claims doesn’t lose any water to evaporation. It says the design requires only a “nominal increase” in energy compared to its data centers that rely on evaporative water cooling. Others seem to be taking a similar approach. EdgeCore also said its 900,000-square-foot data center at the Tahoe Reno Industrial Center will rely on an “air-cooled closed-loop chiller” that doesn’t require water evaporation for cooling.  But some of the companies seem to have taken steps to ensure access to significant amounts of water. Switch, for instance, took a lead role in developing the effluent pipeline. In addition, Tract, which develops campuses on which third-party data centers can build their own facilities, has said it lined up more than 1,100 acre-feet of water rights, the equivalent of nearly 360 million gallons a year.  Apple, Novva, Switch, Tract, and Vantage didn’t respond to inquiries from MIT Technology Review.  Coming conflicts  The suggestion that companies aren’t straining water supplies when they adopt air cooling is, in many cases, akin to saying they’re not responsible for the greenhouse gas produced through their power use simply because it occurs outside of their facilities. In fact, the additional water used at a power plant to meet the increased electricity needs of air cooling may exceed any gains at the data center, Ren, of UC Riverside, says. “That’s actually very likely, because it uses a lot more energy,” he adds. That means that some of the companies developing data centers in and around Storey County may simply hand off their water challenges to other parts of Nevada or neighboring states across the drying American West, depending on where and how the power is generated, Ren says.  Google has said its air-cooled facilities require about 10% more electricity, and its environmental report notes that the Storey County facility is one of its two least-energy-efficient data centers.  Pipes running along Google’s data center campus help the search company cool its servers.GOOGLE Some fear there’s also a growing mismatch between what Nevada’s water permits allow, what’s actually in the ground, and what nature will provide as climate conditions shift. Notably, the groundwater committed to all parties from the Tracy Segment basin—a long-fought-over resource that partially supplies the TRI General Improvement District—already exceeds the “perennial yield.” That refers to the maximum amount that can be drawn out every year without depleting the reservoir over the long term. “If pumping does ultimately exceed the available supply, that means there will be conflict among users,” Roerink, of the Great Basin Water Network, said in an email. “So I have to wonder: Who could be suing whom? Who could be buying out whom? How will the tribe’s rights be defended?”The Truckee Meadows Water Authority, the community-owned utility that manages the water system for Reno and Sparks, said it is planning carefully for the future and remains confident there will be “sufficient resources for decades to come,” at least within its territory east of the industrial center. Storey County, the Truckee-Carson Irrigation District, and the State Engineer’s office didn’t respond to questions or accept interview requests.  Open for business As data center proposals have begun shifting into Northern Nevada’s cities, more local residents and organizations have begun to take notice and express concerns. The regional division of the Sierra Club, for instance, recently sought to overturn the approval of Reno’s first data center, about 20 miles west of the Tahoe Reno Industrial Center.  Olivia Tanager, director of the Sierra Club’s Toiyabe Chapter, says the environmental organization was shocked by the projected electricity demands from data centers highlighted in NV Energy’s filings. Nevada’s wild horses are a common sight along USA Parkway, the highway cutting through the industrial business park. EMILY NAJERA “We have increasing interest in understanding the impact that data centers will have to our climate goals, to our grid as a whole, and certainly to our water resources,” she says. “The demands are extraordinary, and we don’t have that amount of water to toy around with.” During a city hall hearing in January that stretched late into the evening, she and a line of residents raised concerns about the water, energy, climate, and employment impacts of AI data centers. At the end, though, the city council upheld the planning department’s approval of the project, on a 5-2 vote. “Welcome to Reno,” Kathleen Taylor, Reno’s vice mayor, said before casting her vote. “We’re open for business.” Where the river ends In late March, I walk alongside Chairman Wadsworth, of the Pyramid Lake Paiute Tribe, on the shores of Pyramid Lake, watching a row of fly-fishers in waders cast their lines into the cold waters.  The lake is the largest remnant of Lake Lahontan, an Ice Age inland sea that once stretched across western Nevada and would have submerged present-day Reno. But as the climate warmed, the lapping waters retreated, etching erosional terraces into the mountainsides and exposing tufa deposits around the lake, large formations of porous rock made of calcium-carbonate. That includes the pyramid-shaped island on the eastern shore that inspired the lake’s name. A lone angler stands along the shores of Pyramid Lake. In the decades after the US Reclamation Service completed the Derby Dam in 1905, Pyramid Lake declined another 80 feet and nearby Winnemucca Lake dried up entirely. “We know what happens when water use goes unchecked,” says Wadsworth, gesturing eastward toward the range across the lake, where Winnemucca once filled the next basin over. “Because all we have to do is look over there and see a dry, barren lake bed that used to be full.”In an earlier interview, Wadsworth acknowledged that the world needs data centers. But he argued they should be spread out across the country, not densely clustered in the middle of the Nevada desert.Given the fierce competition for resources up to now, he can’t imagine how there could be enough water to meet the demands of data centers, expanding cities, and other growing businesses without straining the limited local supplies that should, by his accounting, flow to Pyramid Lake. He fears these growing pressures will force the tribe to wage new legal battles to protect their rights and preserve the lake, extending what he refers to as “a century of water wars.” “We have seen the devastating effects of what happens when you mess with Mother Nature,” Wadsworth says. “Part of our spirit has left us. And that’s why we fight so hard to hold on to what’s left.”

  • World’s Smallest Mobile Tiny House Is An Ultra-Compact Micro-Camper That Packs A Bed, Shower & Toilet

    YouTuber Levi Kelly, known for his work on compact living spaces, has unveiled what he calls the world’s smallest mobile tiny house. This micro-camper is designed for extreme downsizing yet remains impressively functional, fitting a bed, toilet, and shower into its minimal footprint. While there are many compact camper vans available, Kelly points out that his design stands out for its practical, livable layout, at least for short stays. The result is a surprisingly efficient space that could suit weekend adventures or minimalist travel. Though the claim of being the “world’s smallest” may be up for debate, there’s no doubt this mobile tiny house pushes the boundaries of what’s possible in small-scale living.
    Designer: Levi Kelly

    The micro-camper sits on a Japanese 1998 4×4 Honda Acty pickup, now painted military green instead of its original blue. Other than new wheels and the color update, the truck remains mostly stock. The real transformation is the custom camper shell. Built with a wooden frame, foam insulation, and exterior wall panels, it was carefully designed to stay within the truck’s 800 lbload limit. While the exact weight isn’t specified, it’s close to the maximum. For power, there’s an adjustable solar panel mounted on the roof, which can be reached by a side ladder, and a battery inside to store energy for off-grid use.

    Inside, the micro-camper offers just 21 square feetof space, all arranged within a single multifunctional room. The compact layout is thoughtfully planned, making the most of every inch. The kitchen area features a practical sink with a tap that draws water from a simple bottle system, while wastewater is collected in a separate bottle to keep things tidy. There’s a bit of storage space for small essentials, and a built-in light helps keep the interior bright and usable at night.
    Cooking is handled by a portable hotplate, providing flexibility whether you’re making a quick meal or heating water. For colder nights, a tiny alcohol stove offers a source of warmth without taking up much room. To maintain airflow and comfort, a fan is installed nearby, ensuring the interior stays fresh even when the camper is fully closed up. Despite its small footprint, the space is efficiently organized to deliver the core necessities for short-term living, proving that careful design can make even the tiniest environment functional and comfortable.

    To access the bed, the setup is simple but efficient—the stove is moved aside, and the countertop lifts to reveal a pillow underneath. While Kelly, who is 5 ft 10 in, says he fits comfortably, taller individuals might find the space a bit cramped for sleeping. The bathroom setup is equally creative. A shower head connects to the kitchen tap and can be routed out the window to serve as an outdoor shower.
    For bathroom needs, there’s a dedicated storage compartment housing a camping-style flush toilet. A small bubble window extends from the side of the camper, allowing natural light in and providing extra headroom. This thoughtful detail lets Kelly sit upright on the toilet, making the tiny space feel a little more comfortable and bright.

  • Measles in the Sewers? Wastewater Surveillance Offers Early Warning for Outbreaks

    Monitoring wastewater for traces of infectious diseases is giving this human byproduct a powerful new role in public health. Once used decades ago to detect poliovirus, wastewater-based epidemiology reemerged during COVID-19 and is now proving useful again in tracking measles outbreaks before cases are officially reported.A recent study led by researchers from Baylor College of Medicine, UTHealth Houston, the Houston Health Department, and Rice University showed that measles virus was detected in Houston’s wastewater days before any clinical cases were confirmed. Published in the American Journal of Public Health, the findings come as measles cases rise in Texas and across the U.S.This early detection strategy may offer a new line of defense: spotting outbreaks before they spread.The Measles ComebackMeasles is a highly contagious respiratory virus spread via droplets from coughing or sneezing.

    Measles in the Sewers? Wastewater Surveillance Offers Early Warning for Outbreaks
    Monitoring wastewater for traces of infectious diseases is giving this human byproduct a powerful new role in public health. Once used decades ago to detect poliovirus, wastewater-based epidemiology reemerged during COVID-19 and is now proving useful again in tracking measles outbreaks before cases are officially reported.A recent study led by researchers from Baylor College of Medicine, UTHealth Houston, the Houston Health Department, and Rice University showed that measles virus was detected in Houston’s wastewater days before any clinical cases were confirmed. Published in the American Journal of Public Health, the findings come as measles cases rise in Texas and across the U.S.This early detection strategy may offer a new line of defense: spotting outbreaks before they spread.The Measles ComebackMeasles is a highly contagious respiratory virus spread via droplets from coughing or sneezing.
