Amazon is investing hundreds of millions into the Cascade Advanced Energy Facility, a next-generation small modular reactor project in Richland, Washington, developed with X-energy and Energy Northwest. "The question now is will it be enough to kick off a new wave of U.S. nuclear energy innovation -- a field that America largely soured on by the 1980s?" writes GeekWire. From the report: The facility will be located near Richland, Wash., near Energy Northwest's Columbia Generating Station nuclear plant. The initial goal is to install a cluster of four small modular reactors (SMRs) that can produce up to 320 megawatts of power, but the overall vision is to construct 12 reactors total, with a capacity of nearly one gigawatt. If all the funding, permitting and public support come together, construction should start within the next five years, with the plant coming online in the 2030s. [...] For Amazon, its support of the Cascade Advanced Energy Facility is part of a much bigger initiative. The company has set a goal of deploying 5 gigawatts of nuclear power in the U.S. by 2039. "One thing that Amazon does well is scale technology," said Brandon Oyer, Amazon Web Services' head of power and water for North and South America. "We've done this over and over again ... We'll go and make an investment and then learn how to scale that up, drive out cost, make it more readily available." Targeting SMRs for amplification was a "natural fit," Oyer added. The company believes nuclear aligns with its climate ambitions. Amazon matches all of its electricity use with clean power and is the largest corporate purchaser of wind, solar and other renewable sources. That said, it is struggling to cut its carbon footprint to reach a goal of net-zero emissions by 2040 as the AI-boom stokes energy use. Amazon reported that its carbon footprint grew by 6% last year. Amazon has dibs on half of the 320 megawatts of electricity that will be generated by the first four reactors at the Washington site, but will take all of it if the power prices are too high for local utilities to afford. Cullen said that if everything goes well with the initial phase, it would be straightforward to build the other eight reactors as the permits will encompass the complete build out. The added reactors would produce enough electricity for about one million homes and should come at a lower cost. "Amazon recognizes the role they can -- and are willing -- to play," Cullen said. The company can take some of the early risk and bring that catalytic capital, he said, which is "every, very difficult for utilities to do."

An anonymous reader quotes a report from The Register: Hyperscale datacenters stateside will consume 22 percent more grid power by the end of 2025 than a year ago, and are forecast to need nearly three times as much electricity by the end of the decade. Warnings about datacenters' rising energy draw are coming thick and fast of late, and this latest one from 451 Research (now a part of S&P Global) comes with figures and cautions about how fast this change may occur and what grid resources will be required to meet it. The bit barn building boom is largely fueled by estimated demand for new machine learning models, which require highly configured servers packed with power-hungry GPUs to develop and train. The power and cooling infrastructure required also mean it is easier to build a new facility rather than attempt to retrofit an existing one. As a consequence, utility power to datacenters in America is estimated to jump 11.3 GW to 61.8 GW by the end of this year. 451 calculates this will rise again to 75.8 GW in 2026, then 108 GW in 2028, before hitting 134.4 GW by 2030. These figures also exclude enterprise-owned facilities, only considering those of the hyperscale tech giants such as Amazon, Apple, Google, Meta, and Microsoft, alongside leased and crypto-mining sites. The research identifies Virginia and Texas as the two states with by far the highest requirement for bit barn energy supplies in the US this year. 451 forecasts that Virginia's datacenter load, made up of leased and hyperscale facilities, will reach 12.1 GW in 2025, up from 9.3 GW last year. In Texas, demand is driven by cryptomining and leased capacity, and is slated to hit 9.7 GW this year, from less than 8 GW previously. However, the search for an optimum location is seeing datacenter operators explore emerging markets such as Idaho, Louisiana, Oklahoma and smaller cities in West Texas, looking for "stranded power" and alternative energy generation opportunities, the report says.

Google DeepMind is partnering with Commonwealth Fusion Systems (CFS) to use its Torax AI software to simulate and optimize plasma behavior inside the company's Sparc fusion reactor. TechCrunch reports: There's a reason Google keeps coming back to the problem: AI might be uniquely suited to making fusion power possible. One of the biggest challenges facing fusion startups is keeping the plasma inside a reactor hot enough for long enough. Unlike nuclear fission reactions, which are self-sustaining, fusion reactions are difficult to maintain outside of stars like the Sun. Without that sort of mass and gravity, the plasma is constantly in danger of diffusing and snuffing itself out. In CFS's reactors, powerful magnets substitute for gravity to help corral the plasma, but they're not perfect. Reactor operators have to develop control software that can enable the device to continuously react to changing plasma conditions. Problem is, there are almost too many knobs to turn, certainly more than a human is capable of. That's the sort of problem that AI excels at. Experts have cited AI as one of the key technologies that has enabled the industry's remarkable advances over the past several years. CFS is currently building Sparc, its demonstration reactor, in a suburb outside Boston. The device is about two-thirds completed, and when finished later in 2026, the startup is predicting that it will be the first fusion device capable of producing more power than the plant needs to run itself. Google said Torax can be used with reinforcement learning or evolutionary search models to find the "most efficient and robust paths to generating net energy." The two companies are also exploring whether AI can be used to control the reactor's operation.

Oil, gas and coal will continue to dominate the world's energy mix well beyond 2050, as soaring electricity demand outpaces the shift to renewables, according to a new McKinsey report. From a report: McKinsey expects fossil fuels to account for about 41-55% of global energy consumption in 2050, down from today's 64% but higher than previous projections. U.S. data-center-related power demand is expected to grow nearly 25% a year until 2030, while demand from data centers globally would average 17% growth per year between 2022 and 2030, especially in OECD countries. Alternative fuels are not likely to achieve broad adoption before 2040 unless mandated, but renewables do have the potential to provide 61-67% of the 2050 global power mix, McKinsey said.

An anonymous reader shared this excerpt from a Los Angeles Times newsletter: One of the most consequential moments in California's drive to beat back climate change will take place next month. The state will stop receiving electricity from the Intermountain Power Plant in Central Utah, meaning our reliance on coal as a source of power will essentially be over... [T]he U.S. got nearly half its electricity from coal-fired plants as recently as 2007. By 2023, that figure had dropped to just 16.2%. California drove an even more dramatic shift, getting just 2.2% of its electricity from coal in 2024 — nearly all of it from the Intermountain plant. Operators plan to cut off that final burst of ions next month. "And with improved technology to store power, the change has been made without the power shortages that dogged the state up until 2020..."5

Toyota is fast-tracking its long-promised all-solid-state EV batteries through a new partnership with Sumitomo Metal Mining, aiming to debut its first production vehicle using the technology by 2027 or 2028. Electrek reports: Toyota said that its new batteries could significantly enhance driving range, charging times, and output, potentially transforming the future of automobiles. Compared to current liquid-based batteries, which use electrolyte solutions, Toyota's all-solid-state batteries utilize a cathode, an anode, and a solid electrolyte. According to Toyota, the next-gen battery tech "offers the potential for smaller size, higher output, and longer life." The two companies have been developing cathode materials for all-solid-state EV batteries since 2021, focusing on some of the biggest challenges in producing them at a mass scale. Using Sumitomo Metal Mining's proprietary powder synthesis technology, Toyota claimed to have developed a "highly durable cathode material" for all-solid-state batteries. Sumitomo has been supplying cathode materials for electric vehicles for years, but it's now working to introduce the newly developed tech, moving it toward mass production.

The blackout that left Spain without power last April was the most severe incident to hit European networks in two decades and the first of its kind, according to the European Network of Transmission System Operators for Electricity. Damian Cortinas, the organization's chairman, said the April 28 outage was Europe's first blackout linked to cascading voltages. More than 50 million people lost electricity for several hours. A preliminary report published in July attributed the outage to a chain of power generation disconnections and abnormal voltage surges. The final assessment will be released in the first quarter of next year and presented to the European Commission and member states. A government probe in June found that grid operator Red Electrica failed to replace one of 10 planned thermal plants, reducing reserve capacity. Spain spent only $0.3 on its grid for every dollar invested in renewables between 2020 and 2024, the lowest ratio among European countries and well below the $0.7 average.

Renewables generated 54% of the EU's net electricity in Q2 2025, with solar power emerging as the leading source at nearly 20% of the total mix. Electrek reports: According to new data from Eurostat, renewable energy sources generated 54% of the EU's net electricity in Q2 2025, up from 52.7% year-over-year. The growth came mainly from solar, which produced 122,317 gigawatt-hours (GWh) -- nearly 20% of the total electricity generation mix. June 2025 was a milestone month: Solar became the EU's single largest electricity source for the first time ever. It supplied 22% of all power that month, edging out nuclear (21.6%), wind (15.8%), hydro (14.1%), and natural gas (13.8%). [...] In total, 15 EU countries saw their share of renewable generation rise year-over-year. Luxembourg (+13.5 percentage points) and Belgium (+9.1 pp) posted the most significant gains, driven largely by solar power growth. Across the EU, solar made up 36.8% of renewable generation, followed by wind at 29.5%, hydro at 26%, biomass at 7.3%, and geothermal at 0.4%.

Six months ago California had 48% more public and "shared" private EV chargers than gasoline nozzles. (In March California had 178,000 public and shared private EV chargers, versus about 120,000 gas nozzles.) Since then they've added 23,000 more public/shared charging ports — and announced this week that there's now 68% more EV charger ports than the number of gasoline nozzles statewide. "Thanks to the state's ever-expanding charger network, 94% of Californians live within 10 minutes of an EV charger," according to the announcement from the state's energy policy agency. And the California Energy Commission staff told CleanTechnica they expect more chargers in the future. "We are watching increased private investment by consortiums like IONNA and OEMs like Rivian, Ford, and others that are actively installing EV charging stations throughout the state." Clean Technica notes in 2019, the state had roughly 42,000 charging ports and now there are a little over 200,000. (And today there's about 800,000 home EV chargers.) This week California announced another milestone: that in 2024 nearly 23% of all the state's new truck sales — that's trucks, buses, and vans — were zero-emission vehicles. (The state subsidizes electric trucks — $200 million was requested on the program's first day.) Greenhouse gas emissions in California are down 20% since 2000 — even as the state's GDP increased 78% in that same time period all while becoming the world's fourth largest economy. The state also continues to set clean energy records. California was powered by two-thirds clean energy in 2023, the latest year for which data is available — the largest economy in the world to achieve this level of clean energy. The state has run on 100% clean electricity for some part of the day almost every day this year. "Last year, California ran on 100% clean electricity for the equivalent of 51 days," notes another announcement, which points out California has 15,763 MW of battery storage capacity — roughly a third of the amount projected to be needed by 2045.

Electric powertrains allow for "crazy fast acceleration figures," reports Car and Driver, as well as "huge power numbers." And now a Chinese luxury electric car brand owned by BYD Auto "just hit a top speed of 308.4 mph, making it not only the fastest electric car on the planet, but the fastest car. Period." Engadget reports that the U9 Xtreme "is packed with four motors that produce just under 3,000 horsepower. The electric hypercar also runs on one of the world's first 1,200V platforms, which offers better performance and efficiency, along with some weight reduction." And Car and Driver adds that "Other changes to achieve the speed include dropping the wheel size from 21 to 20 inches, narrowing the front track, and adding wider, semi-slick track tires at the front of the car." One small caveat that doesn't lessen the impressiveness of the feat is that while the U9 Xtreme does classify as a production model, it barely does. That's because BYD is planning to limit production of the top-speed version of the U9 to no more than 30 units. The car hit its "facemelting" top speed during a livestream at Germany's Automotive Testing Papenburg, reports Engadget. Thanks to long-time Slashdot reader hackingbear for sharing the news.

An anonymous reader quotes a report from The Register: Renewable energy sources could power datacenters at a lower cost than relying on nuclear generation from small modular reactors (SMRs), claims a recently revealed study. ... [A]nalysis from the Centre for Net Zero (CNZ) says it would cost 43 percent less to power a 120 MW data facility with renewables and a small amount of gas-generated energy, when compared with an SMR. It claims that a microgrid comprising offshore wind, solar, battery storage, and backed up by gas generation, would be significantly cheaper to run annually than procuring power sourced from a nuclear SMR. [...] CNZ describes itself as an open research institute, founded by Octopus Energy Group in the UK, and claims to advise the State of California and Europe's International Energy Agency as well as the British government. While CNZ's study applies to the UK sector, where energy costs are among the highest in the industrialized world, it is likely that the overall conclusion would still be valid in other countries as well. Its analysis shows that renewables can meet 80 percent of the constant demand from a large datacenter over the course of a year. Offshore wind can provide the majority of load requirements, with gas generation backed by battery storage as a stopgap source of power representing the most cost-optimal mix. Greater capacity in the on-site battery storage system would reduce the reliance on gas power, and this would likely happen over time as the cost of such systems is expected to come down, the report claims. But perhaps the real kicker is that CNZ estimates that microgrids powered largely by renewables could be built in approximately five years, while operational SMRs are not expected to be widely available until sometime in the next decade. CNZ says that it calculated the typical yearly resource cost (capex and opex) of powering a datacenter with a nuclear SMR, and modeled this using Python for Power System Analysis (PyPSA), an open source energy modeling tool, against two renewable energy scenarios. One was the wind, solar, battery, and gas mix, while the other omitted solar.

US wholesale electricity prices have nearly doubled since 2020, rising faster than consumer rates across most regional grid operators. Analysis of location marginal pricing data from 17 trading hubs shows average wholesale costs increased from baseline 2020 levels to peaks 2-4 times higher by 2022, before partially recovering. Consumer electricity prices rose 35% during the same period. Transmission congestion spreads are widening in most Independent System Operators and Regional Transmission Organizations, particularly in PJM, SPP, and NYISO, where bottlenecks increasingly prevent access to cheaper generation. California's CAISO stands alone among major grid operators as wholesale prices remain flat or decline in 2025 despite natural gas volatility. The cheapest wholesale electricity continues to trade in SPP's Oklahoma-Kansas region at $16-17 per megawatt-hour.

RestOfWorld.org reports on "a global crisis nobody anticipated when governments started subsidizing electric vehicles..." "EVs can lose almost half their driving distance when temperatures drop, and the billions spent on improving technology have failed to fix this fundamental limitation." In January, Seattle-based Recurrent, a company that tests and analyzes EVs, found an average range loss of 20% in extreme cold... Lithium-ion batteries rely on chemical reactions that slow dramatically in cold weather. When temperatures plunge, the electrolyte thickens, ions move sluggishly, and charging becomes not just inefficient but potentially dangerous. Charging in cold weather has been identified as a primary cause of thermal acceleration, which can lead to fires... The failure pattern repeats globally wherever cold weather meets inadequate infrastructure. Manufacturers, too, have acknowledged the problem. Chinese EV maker BYD's user manual, for instance, advises drivers to charge indoors, with the heating on. That advice is useless for farmers parking in open courtyards. In fact, research across 293 Chinese cities "found that many drivers in colder regions buy EVs only as supplementary vehicles," according to the article, "while still relying on gasoline-powered cars during winter." The article also tells the story of an apple grower chilly Kashmir, India who discovered that his Chinese three-wheeler lost 60% of its 10-hour charge overnight. This made it impossible to begin the 56-kilometer (35-mile) trip on a route with no charging stations — and prevented him from selling his produce while it was fresh (to earn the highest prices). And the problem affects the entire region: Desperate drivers have formed WhatsApp groups, such as "EV Apple Transporters" and "Battery Help Kashmir," sharing increasingly absurd workarounds. Some have wrapped batteries in quilts; others have hauled power packs weighing 90 kilograms (over 200 pounds) into their homes for the night. One driver parked his battery in the living room. "The blankets caused overheating on the road; water bottles leaked into the circuits," [orchard owner] Sajad Ahmad said. "We became mechanics, engineers, and fools all at once." EVs are also not considered cost-efficient. "Diesel vans are expensive, but they can do four or five trips a day," Mohammad Yaseen, a driver based in Shopian, told Rest of World. "With EVs, one half-trip and you're stuck." Norway, where winter temperatures average minus 7 degrees Celsius (19 degrees Fahrenheit), achieved 89% EV market share with its comprehensive infrastructure. It offers more than 200 models for year-round usage. "The ability to preheat batteries upon fast charging in winter is by far the most important improvement we have seen in the past five years," Christina Bu, secretary-general of the Norwegian EV Association, told Rest of World. "These features are standard in Norway's mature market, but remain absent from basic models exported to developing countries."

They offer "a self-sustaining power solution for marine regions," according to a newly published 41-page review after "pioneering use in wave energy harvesting in 2014". Ten years later, researchers have developed several structures for these "triboelectric nanogenerators" (TENGs) to "facilitate their commercial deployment." But there's a lack of "comprehensive summaries and performance evaluations". So the review "distills a decade of blue-energy research into six design pillars" for next-generation technology, writes EurekaAlert, which points the way "to self-powered ocean grids, distributed marine IoT, and even hydrogen harvested from the sea itself..." By "translating chaotic ocean motion into deterministic electron flow," the team "turns every swell, gust and glint of sunlight into dispatchable power — ushering in an era where the sea itself becomes a silent, self-replenishing power plant." Some insights: - Multilayer stacks, origami folds and magnetic-levitation frames push volumetric power density...three orders of magnitude above first-generation prototypes. - Frequency-complementary couplings of TENG, EMG and PENG create full-spectrum harvesters that deliver 117 % power-conversion efficiency in real waves. - Pendulum, gear and magnetic-multiplier mechanisms translate chaotic 0.1-2 Hz swells into stable high-frequency oscillations, multiplying average power 14-fold. - Resonance-tuned structures now span 0.01-5 Hz, locking onto shifting wave spectra across seasons and sea states. - Spherical, dodecahedral and tensegrity architectures harvest six-degree-of-freedom motion, eliminating orientational blind spots. - Single devices co-harvest wave, wind and solar inputs, powering self-charging buoys that cut battery replacement to zero... Another new wave energy project is moving forward, according to the blog Renewable Energy World: Eco Wave Power, an onshore wave energy technology company, announced that its U.S. pilot project at the Port of Los Angeles has successfully completed operational testing and achieved a new milestone: the lowering of its floaters into the water for the first time. The moment, broadcast live by Good Morning America, follows the finalization of all installation works at the project site, including full installation of all wave energy floaters; connection of hydraulic pipes and supporting infrastructure; and placement of the onshore energy conversion unit. With installation completed, Eco Wave Power has now officially entered the operational phase of its U.S. excursion... [Inna Braverman, founder and CEO of Eco Wave Power] said "This pilot station is a vital step in demonstrating how wave energy can be harnessed using existing marine infrastructure, while laying the groundwork for full-scale commercialization in the United States...." Eco Wave Power's patented onshore wave energy system attaches floaters to existing marine structures. The up-and-down motion of the waves drives hydraulic cylinders, which send pressurized fluid to a land-based energy conversion unit that generates electricity... The U.S. Department of Energy's National Renewable Energy Laboratory estimates that wave energy has the potential to generate over 1,400 terawatt-hours per year — enough to power approximately 130 million homes. Eco Wave Power's 404.7 MW global project pipeline also includes upcoming operational sites in Taiwan, India, and Portugal, alongside its grid-connected station in Israel. Long-time Slashdot reader PongoX11 also brings word of a company building a "simple" floating rig to turn wave motion into electricity, calling it "a steel can that moves water around" and wondering if "This one might work!" The news site TechEBlog points out that "Unlike old-school wave energy systems with clunky mechanical parts, Ocean-2 rocks a modular, flexible setup that rolls with the ocean's flow." At about 10 meters wide [30 feet wide. and 260 feet long!], it is made from materials designed to (hopefully) withstand the ocean's abuse, over some maintenance cycle. It's designed for deep ocean, so solving this technically is the first big challenge. Figuring out how to use/monetize all that cheap energy out in the middle of nowhere will be the next. "Ocean-2 works with the ocean, not against it, so we can generate power without messing up marine life," said Panthalassa's CEO, Dr. Elena Martinez, according to TechEBlog: Tests in Puget Sound, done with Everett Ship Repair, showed it pumping out up to 50 kilowatts in decent conditions — enough juice for a small coastal town. "We're thinking big," Martinez said in a press release. "Ocean-2 is just the start, but we're already planning bigger arrays that could crank out gigawatts..." Looking forward, Panthalassa sees Ocean-2 as part of a massive wave energy network. By 2030, they're aiming to roll out arrays that could power whole coastal cities, cutting down on fossil fuel use.

When it comes to nuclear fusion energy, "How do we advance fusion as fast as possible?" asks the CEO of Commonwealth Fusion Systems. They've just raised $863 million from Nvidia, Google, the BIll Gates-founded Breakthrough Energy Ventures and nearly two dozen more investors, which "may prove helpful as the company develops its supply chain and searches for partners to build its power plants and buy electricity," reports TechCrunch. Commonwealth's CEO/co-founder Bob Mumgaard says "This round of capital isn't just about fusion just generally as a concept... It's about how do we go to make fusion into a commercial industrial endeavor." The Massachusetts-based company has raised nearly $3 billion to date, the most of any fusion startup. Commonwealth Fusion Systems (CFS) previously raised a $1.8 billion round in 2021... CFS is currently building a prototype reactor called Sparc in a Boston suburb. The company expects to turn that device on later next year and achieve scientific breakeven in 2027, a milestone in which the fusion reaction produces more energy than was required to ignite it. Though Sparc isn't designed to sell power to the grid, it's still vital to CFS's success. "There are parts of the modeling and the physics that we don't yet understand," Saskia Mordijck, an associate professor of physics at the College of William and Mary, told TechCrunch. "It's always an open question when you turn on a completely new device that it might go into plasma regimes we've never been into, that maybe we uncover things that we just did not expect." Assuming Sparc doesn't reveal any major problems, CFS expects to begin construction on Arc, its commercial-scale power plant, in Virginia starting in 2027 or 2028... "We know that this kind of idea should work," Mordijck said. "The question is naturally, how will it perform?" Investors appear to like what they've seen so far. The list of participants in the Series B2 round is lengthy. No single investor led the round, and a number of existing investors increased their stakes, said Ally Yost, CFS's senior vice president of corporate development... The new round will help CFS make progress on Sparc, but it will not be enough to build Arc, which will likely cost several billion dollars, Mumgaard said. "As advances in computing and AI have quickened the pace of research and development, the sector has become a hotbed of startup and investor activity," the article points out. And CEO Mumgaard told TechCrunch that their Sparc prototype will prove the soundness of the science — but it's also important to learn "the capabilities that you need to be able to deliver it. It's also to have the receipts, know what these things cost!"

"Delta Air Lines Flight 1334 was flying from Atlanta to Fort Lauderdale last month when smoke and flames started pouring out of a backpack," reports CNN. "The pilots declared an emergency and diverted to Fort Meyers where the 191 people onboard safely evacuated." The culprit was a passenger's personal lithium-ion battery pack, which had been tucked away in the carry-on bag. At the FAA's William J. Hughes Technical Center for Advanced Aerospace in Atlantic City, New Jersey, fire safety engineers research and demonstrate just how bad it can be. "Lithium batteries can go into what's called thermal runaway," Fire Safety Branch Manager Robert Ochs, explained. "All of a sudden, it'll start to short circuit ... It will get warmer and warmer and warmer until the structure of the battery itself fails. At that point, it can eject molten electrolyte and flames and smoke and toxic gas...." These thermal runaways are difficult to fight. The FAA recommends flight attendants first use a halon fire extinguisher, which is standard equipment on planes, but that alone may not be enough. In the test performed for CNN, the flames sprung back up in just moments... "Adding the water, as much water from the galley cart, non-alcoholic liquids, everything that they can get to just start pouring on that device." The problems are not new, but more batteries are being carried onto planes than ever before. Safety organization UL Standards and Engagement says today an average passenger flies with four devices powered by lithium-ion batteries. "The incidents of fire are rare, but they are increasing. We're seeing as many as two per week, either on planes or within airports," Jeff Marootian, the president and CEO of the organization, told CNN... [T]he latest federal data shows external battery packs are the top cause of incidents, and as a result the FAA has banned them from checked baggage where they are harder to extinguish. But despite all of the warnings, UL Standards and Engagement says two in five passengers still say they check them.
