But size isn’t the only reason its climate toll will be so high.
Amazon has acquired a massive off-grid power plant being built in Texas for one of its data centers that could be one of the biggest sources of greenhouse gas emissions in the US.But size isn’t the only reason its climate toll will be so high. The plant will rely on a much less efficient set of gas turbines than regular power plants use; these kinds of turbines are also increasingly being put to use at other data center projects around the US. That could have big implications for the environmental impact of artificial intelligence—and the future of the US grid.Amazon’s Texas power plant is permitted to emit up to 33 million tons of greenhouse gases a year. The project will rely solely on simple cycle turbines, which mix fuel and air in a combustion chamber to create energy, letting off a significant amount of waste heat in the process. Combined cycle units, which are generally used at on-grid power plants, add an additional steam turbine component to capture the waste heat and turn it into more energy. That means they release fewer emissions for the same amount of energy.Permitted emissions on natural gas plants are usually much higher than their actual emissions. But even if Amazon’s facility emits half of what’s on the permit each year, it would still create more greenhouse gas pollution than 78 average-sized natural gas plants, according to the US Environmental Protection Agency.The Texas plant provides “on-site generation that won't raise electricity costs for Texas families,” Amazon spokesperson Heather Callahan writes in an email to WIRED, adding that the site would also have solar and battery storage and that the company is still committed to reaching net-zero emissions by 2040.Using simple-cycle turbines is becoming an increasingly common practice for data center power developers looking for flexible power that’s quick to install. At least three power plants being developed in Ohio by oil and gas company Williams for Meta will also rely on simple cycle units, according to permit applications. In Abilene, Texas, Crusoe is building a power plant on its Stargate campus to power a Microsoft data center with 39 simple-cycle turbines. The permit application for Google’s Goodnight data center at another Texas site being developed by Crusoe describes relying on 20 simple-cycle turbines. And both xAI’s Colossus 1 and Colossus 2 data centers in Memphis are being powered by dozens of simple cycle turbines. All of them are permitted to release millions of tons of greenhouse gases. (Both Williams and Crusoe tell WIRED in an email that their gas plants comply with local and national regulations and are outfitted with emissions control technology.)Britt Burt, a senior vice president at Industrial Info Resources, an energy market intelligence firm, says that he didn’t expect data center developers to lean so heavily on simple cycle turbines for power.“It’s not the most efficient way to use a gas turbine,” he says.For companies racing to get data centers online, though, it’s a lot quicker—and cheaper—to install a handful of simple-cycle turbines than wait for the additional equipment needed for combined-cycle units, especially given a yearslong backlog for turbine orders and associated parts.“Right now, because of the way the supply chain is for turbines, they’re having to go with what they can get their hands on,” says Burt.Then there’s the energy needs of data centers, especially those training AI models. Thanks to their fewer moving parts, simple cycle turbines can start up and shut down more rapidly than combined cycle units. That suits AI training, which requires big spikes of energy on demand. (In fact, those spikes are so big that many data center operators have reported turbines breaking thanks to the extreme stress of turning on and off.)“If you have a highly fluctuating load, it's better to have 30 things that can individually turn on and off than to have one giant thing that doesn't like to be turned on and off,” says Stephe
In Brief Posted: 3:24 PM PDT · August 12, 2026 Image Credits:James Marvin Phelps (opens in a new window) Fermi, the AI nuclear power firm, has named a new CEO more than three months after firing co-founder Toby Neugebauer from the top executive post. Fermi said Wednesday it has hired Lee McIntire, an independent member of the company’s board who has held chief executive positions at CH2M Hill and TerraPower, the nuclear power startup founded by Bill Gates. Fermi America, which was co-founded by former U.S. Energy Secretary Rick Perry, is developing an AI campus in Amarillo, Texas, called Project Matador that will eventually use nuclear reactors to power data centers. The announcement, along with Monday’s news that it had signed TensorWave as its first binding customer lease for its Project Matador campus, provided a welcome boost to Fermi’s stock. (The stock is up nearly 23% since Monday.) The young company took a hit in April when Neugebauer and CFO Miles Everson were pushed out of the company. At the time, the company described the executive shakeup, along with other plans including a corporate headquarters in Dallas, as Fermi 2.0. “Fermi’s next chapter is a construction and power delivery story, and we believe Lee is the ideal executive to lead Fermi through that process,” Marius Haas, Fermi’s chairman of the board, said in a statement. “The job now is to build on schedule, on budget, and safely. Lee has spent 40 years delivering exactly this kind of large, complex project. He also knows Fermi from the inside, having served on our board through our latest period of growth, and he brings a reputation for integrity that Fermi’s customers, employees, regulators, and neighbors can rely on.” Topics Subscribe for the industry’s biggest tech news Latest in Climate
In the fusion power world, most of the attention gets lavished on the reactors themselves, where atoms fuse to unleash enormous amounts of energy. But a fusion reactor can’t run for long without a lot of other equipment, and building a fusion reactor is expensive enough on its own. Plenty of startups are happy to let someone else handle the rest. Among the dozens of companies in the emerging fusion power supply chain, few specialists are bigger than Kyoto Fusioneering. The Japan-based company has raised $121 million in committed capital, according to FusionX. Now it has landed grants from the U.S. Department of Energy and the state of Tennessee to build a prototype fuel breeding device at Oak Ridge National Laboratory (ORNL). Alongside the announcement, Kyoto Fusioneering exclusively told TechCrunch that it’s moving its U.S. headquarters to Oak Ridge. The startup has emerged as a key player in the fusion power industry. Over half of fusion startups have said they plan to work with external suppliers like Kyoto Fusioneering on fuel cycle technologies, according to a recent Fusion Industry Association survey. Kyoto Fusioneering’s forthcoming device, called Unity-3, is being developed with ORNL and will test a fuel cycle technology known as a breeding blanket. Breeding blankets harvest energy from the fusion reactor while also generating fresh fusion fuel. One breeding blanket design will use liquid lithium, which will absorb both heat and neutrons. As the lithium atoms in the blanket are bombarded with neutrons, they split into helium and tritium, an isotope of hydrogen that’s an important fuel for many reactor designs. The tritium is then separated from the blanket and sent to the reactor, while heat is extracted to generate power. All of this requires heat-resistant materials, bespoke pumps, and other specialized equipment, and it’s just one slice of a fusion power plant that needs to be developed before it can connect to the grid. Kyoto Fusioneering is also developing systems to heat fusion fuel into a plasma, recycle unburned fuel from the exhaust, and harvest heat to generate electricity. Unity-3 will test the performance of not just liquid lithium, but a range of other breeding blanket materials, Kyoto Fusioneering told TechCrunch. The device will help researchers and startups validate the data they’ve been generating, so far mostly through computer models. Other fusion startups, including Realta Fusion, Thea Energy, Type One Energy, and Xcimer Energy, will use data from the Unity-3 experiments to design their reactors. It’s a range of startups — and approaches to fusion power — that should help position Kyoto Fusioneering as a go-to supplier when fusion power is ready for the grid.

Clicks Technology, the startup determined to bring back physical keyboards to smartphones, began shipping its now-$99 MagSafe-compatible Power Keyboard this summer, after some delays. As of last week, 75% of the pre-orders from the first batch had shipped to customers. Designed to work with a range of devices, this new, slide-out keyboard with tactile buttons can accommodate different phone sizes and can be used in either portrait or landscape mode, the company says, giving any phone a BlackBerry-like feel. The device is something of a teaser for what’s to come when Clicks ships its first smartphone, the BlackBerry-like Clicks Communicator, also featuring a physical keyboard, later this year. Like the upcoming smartphone, the idea behind the Power Keyboard is to provide an alternative to onscreen keyboards for those who miss the speed and reliability that came with typing on a small, physical keyboard. However, in its current implementation, the Power Keyboard suffers from the same fate as the company’s earlier Clicks keyboard — a smartphone case that included a physical keyboard. It can make the phone feel top-heavy and difficult to hold in portrait mode, especially if you’re using a larger smartphone as I did in tests with the iPhone 17 Pro Max and Pixel 10 XL. Still, the device itself is crafted with care, and could appeal to those who still desperately long for their BlackBerry. Image Credits:Clicks Technology Unboxing the device, we noticed the Power Keyboard was nicely packaged as a premium device would be, with peel-away cling films to prevent scratches during shipping and a full-color Quick Start guide to using the product. You may first need to charge the device’s battery via USB-C, though we found ours shipped with a charge already. To pair the device with your phone over Bluetooth, press and hold the power button and slide out the keyboard. We quickly paired the device with our Android phone. We ran into trouble once we switched over to the iPhone. Even after “forgetting” the device on Android, it still refused to pair with our iPhone. Returning to the instructions, it appears this was our mistake. The trick is to press a number key alongside the power button on the keyboard to add a second Bluetooth device. (The only way to actually “forget” a device is by removing it from its slot using the Clicks mobile app.) The keyboard attaches to your phone via MagSafe or Qi2. If your phone doesn’t support either technology, you could opt to use an adhesive ring or a phone case that adds the magnetic power profile instead. Image Credits:Clicks Technology Once connected, you can then pull the keyboard out when you need to type. Helpfully, the keyboard adjusts to different phone sizes, so it will work with standard models as well as larger “Ultra” or “Pro Max” devices. We appreciated the satisfying clicks as the keyboard locked into place on the various sliders. The keyboard offers an adjustable LED backlight, so you can type in the dark. The keys themselves have a nice, clicky feel and are well-placed, making them easy to reach. While it takes quite a bit of adjustment after years of on-screen keyboards to return to pressing buttons, the learning curve is less steep than it was on the earlier Clicks keyboard case. It’s clear that the company has been iterating on what it learned with its older device, and those lessons have been channeled into this product. In addition, while Clicks’ older keyboard case pulled power from the phone by way of its USB-C connection, the Power Keyboard instead includes a built-in 2,150 mAh battery. Image Credits:Clicks Technology The product itself has a slimmer profile than some snap-on battery packs, at 119.7 × 76.6 × 15.2mm, and doesn’t add an unreasonable amount of weight at 180 grams. Nevertheless, this is not something that would fit well in a woman’s pants pocket. The keyboard could get caught on a back pocket as well, as it could slide open if you press against the device whi
Vogue World is coming to San Francisco next year — perhaps another indication that tech billionaires have become leaders in the fashion zeitgeist. Of course, the announcement of the enormous fashion/art/music event doesn’t say that. Instead, Anna Wintour wrote that Vogue believes in celebrating cities and “San Francisco is a city like none other.” “It’s a place of diverse communities living side by side, a place that loves the arts, loves creativity, and isn’t afraid of change.” She also noted the city’s history of rebelliousness and innovation. “I love that San Francisco has always stood up for values and the things it believes in,” Wintour wrote. “Vogue World will support San Francisco’s creative minds and strengthen the entire ecosystem — and it will offer another opportunity to show San Francisco is on the rise.” There were rumors that Vogue World would head to San Francisco after Winter was seen having meetings with the city’s mayor, Daniel Lurie. Plus, in the past year, Wintour has cozied up to the most powerful names in tech, culminating in this year’s Met Gala, which saw Jeff Bezos and his wife, Lauren Sanchez, serve as lead sponsors for the event. Google’s Sergey Brin and Mark Zuckerberg were also spotted at the event (the latter’s first, that is). In fact, OpenAI bought a table, as did Meta and Snap (for $350,000 a pop). It’s true that TikTok, Apple, and Instagram previously sponsored the event, but the presence of the tech crowd this year was so much that the Met Gala this year was dubbed the “tech gala” in some places. Last year, Vogue put Lauren Sanchez on the cover of the magazine after her wedding to the Amazon founder. To the fashion world, this was Wintour’s stamp of approval — not just for Sanchez’s ascent into the fashion world, but that tech and its leaders were worthy of cultural recognition. Though Bezos and Sanchez reportedly live in Florida (and Amazon is, of course, headquartered in the Seattle area), there is no city more associated with tech than San Francisco. By locating Vogue World there, this is another indication of Wintour’s approval. Vogue, as a media publication, is always following the money, and as a cultural bible, is always looking for ways to stay relevant. Turning toward the worldwide headquarters of AI, good or bad, is brilliant for business (and Wintour is nothing if not brilliant). But Vogue World was previously held in New York, London, Paris, and this year, Milan. Maybe because I live in an East Coast bubble, but I’ve not heard anyone in recent years refer to San Francisco as a beacon of style to rank alongside these other cities. While the city has a reputation as the land of the free-spirited bohemian, tech and its workers have a reputation for hoodies, Patagonia vests, and expensive athletic shoes, if they even dress up that much. For instance, billionaire Alexandr Wang, who is now running Meta’s all-important Superintelligence Labs, just did an interview with Y Combinator’s Garry Tan in front of a packed stadium wearing a faded Nintendo T-shirt and what looked like a pair of Crocs. Comfy? Yes. High fashion? Decidedly no. But maybe that’s changing. Wang’s boss, Mark Zuckerberg, who once always appeared in a plain gray T-shirt and jeans, has made efforts in recent years to become more fashionable. Zuck and his wife Priscilla Chan were spotted front row at a Prada show this season. The new campaign for Meta Glasses has a slew of celeb ambassadors and looks like it could be a Saint Laurent or Balenciaga ad. OpenAI and Palantir have recently released merch collabs, playing on the minimalist style of tech workers (the merch line of the latter, I would argue, looks inspired by Virgil Abloh’s Off-White). I concede that creatively there is much to be done with the understated, Northern California style. Surrounded by beautiful nature and cooler temperatures, plenty of fashion designers could be motivated by San Francisco’s tech industry. I look forward to seeing Claude-ins
Autonomous car maker Waymo has dropped the waitlist for its robotaxi service in Dallas, opening it up to all residents and visitors. This is the latest step in the Alphabet-owned company’s bid to scale its self-driving technology across Europe, the United Kingdom, and the United States. Waymo said Tuesday that anyone can now download the app and immediately hail one of its robotaxis in Dallas. For now, riders won’t be able to hail a ride to Dallas Love Field Airport. The company said it continues to test its self-driving vehicles at the airport and expects to serve riders there “soon.” The company has had a presence in Dallas since last year, when it began testing its technology on public streets and announced plans to launch the service there in 2026. At the time, the company said it would partner with Avis Budget Group to manage its fleet of all-electric autonomous Jaguar I-Pace vehicles. Avis handles general depot operations, including charging and maintaining the vehicles. Waymo opened the service to the public in February, but initially limited access through a waitlist. Waymo said about 150,000 riders used the Waymo app during this period. Waymo no longer has the waitlist, following a robotaxi playbook that it has used in every other market, including Phoenix, Los Angeles, and San Francisco. The company’s entry into Dallas had some early hiccups. In May, Waymo paused its service in Dallas, Houston, and San Antonio, Texas, as well as Atlanta, due to problems with how its robotaxis handled heavy rain and flooded roads. While robotaxi services have resumed in these cities, Waymo said it may adjust or temporarily pause operations based on severe weather, flood warnings, and real-time conditions in the future. A Waymo spokesperson said riders can check the status of its service via the Waymo app. When you purchase through links in our articles, we may earn a small commission.

Waymo is slowly adding freeway routes back to its service area more than two months after the company stopped driving these high-speed roads over how its rovotaxis behaved near construction zones. Waymo announced Wednesday in a post on X that it would gradually add freeway routes, starting with Phoenix — the company’s first driverless ride-hailing market. More cities, including Los Angeles and the San Francisco Bay Area, would follow in the coming days, a Waymo spokesperson told TechCrunch. In an emailed statement, Waymo said it was “resuming freeway operations across its entire service area, including areas with construction, after implementing software updates designed to improve performance around freeway construction zones.” Those software updates improved performance around construction zones through enhanced scene recognition and routing, according to the company. The freeway pause — and its restart — comes amid increased scrutiny into Waymo and other robotaxi operators, particularly over how these self-driving vehicles behave in certain high-traffic situations and around emergency responders. Earlier this week, Rep. Kevin Mullin (D-Calif.) proposed a bill that would direct federal regulators to establish minimum national safety standards for autonomous vehicle operators following a number of incidents in which autonomous vehicles blocked ambulances and fire trucks, drove into active crime scenes, and failed to recognize safety signals such as traffic cones and flares. Waymo started offering robotaxi rides that used freeways across San Francisco, Phoenix, and Los Angeles in November 2025, a critical expansion for the company as it sought to attract riders with shorter commute times and faster access to airports. It would later add freeway routes in Miami. The expansion proved to be popular, and when it suddenly disappeared in May, riders took to social media to ask why. At the time, Waymo told TechCrunch it wanted to improve the performance of its robotaxis in construction zones, noting that it was in the process of integrating “recent technical learnings into our software and expect to resume these routes soon.” Weeks later, Waymo voluntarily recalled its fleet of nearly 4,000 robotaxis after identifying at least 13 instances of its robotaxis driving into highway sections that were closed for construction, according to a filing submitted in June with the National Highway Traffic Safety Administration. A Waymo spokesperson said there were no injuries or collisions reported in connection with these events. However, after reviewing the incidents, the company said it decided to temporarily restrict freeway operations. This was Waymo’s sixth recall of its robotaxis. Previous recalls included software fixes after its robotaxis drove into flooded roads and behaved illegally around school buses.

In Brief Posted: 1:43 PM PDT · July 24, 2026 Image Credits:Eric Thayer/Los Angeles Times / Getty Images Waymo is reportedly looking for a way out of its deal with Uber, which has made the Alphabet-owned company’s robotaxis available on the ride-hailing giant’s network in Austin and Atlanta, according to the Financial Times. Waymo already told Uber that it intends to offer robotaxis on its own app in those markets starting in January 2028 and alongside the existing offering, the ride-hail giant told TechCrunch on Friday. Uber said the contract with Waymo that covers Austin and Atlanta ends in May 2028. The two companies already split in Phoenix earlier this year, as TechCrunch first reported. Waymo didn’t immediately respond to a request for comment. This all follows months of rising tensions between Waymo and Uber. Earlier this year, Uber CTO Praveen Neppalli posted a video of what he thought was unsafe and “scary” behavior of a Waymo robotaxi. In May, Uber CEO Dara Khosrowshahi lightly criticized the behavior of Waymo’s robotaxis in school zones and emergency situations during an earnings call, though without naming the company. Waymo, meanwhile, has wound up opposite Uber in a number of fresh policy fights over robotaxi regulations. Topics Subscribe for the industry’s biggest tech news Latest in Transportation
Waymo said it’s making “temporary adjustments” to its robotaxi service in San Francisco amidst a power outage that appears to have affected around 7,000 PG&E customers in the city. According to a screenshot posted on social media, Waymo is telling SF customers that service is “temporarily paused” and that “freeway routes are unavailable.” When TechCrunch reached out to the Alphabet-owned company for comment, a spokesperson said in a statement, “We are making temporary adjustments to our service while we monitor local conditions. We know riders depend on us, and we will return to normal operations as soon as possible.” This isn’t the first time power outages have caused issues for Waymo. A number of Waymo vehicles stalled on city streets during a blackout in December, and a similar incident paralyzed traffic during a Golden Gate Bridge fireworks show on the Fourth of July. As a result, San Francisco Mayor Daniel Lurie has called for tougher state regulations to “adequately address how autonomous vehicles operate during major incidents, planned or not.”
