Small Modular Nuclear Reactor Reaches Criticality In First Test

5 June 2026 at 22:30
An anonymous reader quotes a report from Ars Technica: Just over a year ago, the Trump Administration issued an executive order meant to accelerate the development of nuclear power in the US. While an entire startup ecosystem has developed around the use of different -- and typically smaller -- reactor designs, only one of them has been fully licensed so far, and there are no plans to actually build any instances of that design. The executive order directed the Department of Energy to have three different reactor designs reach criticality in a bit over a year. On Thursday, a startup called Antares announced that a test reactor it had placed at the Idaho National Laboratory had reached criticality, making it the first new design to cross this threshold. Criticality means that the nuclear reactions inside the hardware had become self sustaining; it does not mean the reactor had started to generate power. [...] At the moment, Antares is just testing what it calls a Mark 0 reactor, which is not connected to the power-generation portion. Instead, it's being used to validate the company's modeling of the physical conditions in its reactors and generate safety data that can be used during licensing applications. Attempts to run the entire system, including electrical generation, are expected to happen next year. While the work was done at a Department of Energy Lab, the company is working with the Department of Defense's Project Pele program for developing a mobile nuclear reactor. The company has also received support from NASA.

Used Waymo Robotaxi Batteries Become Backup Storage For Power Grids

5 June 2026 at 02:00
Waymo and B2U Storage Solutions have struck a "strategic supply agreement" to repurpose used batteries from Waymo's electric robotaxi fleet into stationary storage for California and Texas power grids. The arrangement could give robotaxi batteries a second life storing renewable energy after they're no longer suitable for vehicle use. It will also "support B2U projects in regions where Waymo's autonomous robotaxis operate -- meaning the used Waymo batteries could bolster the local power grids that Waymo vehicles rely upon for charging," reports Ars Technica. From the report: Waymo's "proactive maintenance" for its autonomous vehicles includes identifying opportunities to "refresh the battery to improve efficiency overall for our fleet," Adam Lenz, head of sustainability and environment at Waymo, told Ars. "That's when we look to these second-life applications, because there's still a lot of life left in the battery," he said. Waymo did not specify the average mileage at which it swaps out batteries or retires vehicles from service. But Waymo robotaxis drive around much more each day than the typical EV, which means the Waymo fleet is likely to experience faster usage-related degradation of battery capacity over time. The company confirmed to Ars that "some of these vehicles have now been serving riders for years and have mileage beyond what a normal consumer drives." [...] "Put a little haircut on that in terms of degradation and the effective capacity that would be left in those batteries when they're suitable for repurposing, and we're still talking about pretty significant capacity per battery," Hall said. The growing Waymo robotaxi fleet could lead to "pretty large numbers in terms of megawatt hours of capacity that can be deployed pretty quickly" for stationary energy storage supporting power grids, he suggested. The agreement gives Waymo discretion over when and how many used batteries will be turned over to B2U. But the companies confirmed that B2U has "already started receiving smaller initial quantities of batteries" from the Waymo fleet. Over time, the agreement could give B2U "hundreds of megawatt-hours" of additional storage capacity from Waymo's thousands of electric vehicles, Lenz said.

User-Replaceable Batteries Are Coming Back In a Big Way

2 June 2026 at 11:00
New EU battery rules taking effect early next year are pushing tech makers toward user-replaceable batteries in products like headphones, e-readers, handheld consoles, laptops, and possibly earbuds. But carve-outs for smartphones and tablets may mean replaceable batteries won't necessarily return to phones in the way many users remember. The Verge's Dominic Preston reports: Since the upcoming law doesn't actually come into force until February 18th, 2027, companies still have plenty of time to get their ducks in a row. Still, it's likely that before then we'll see more and more manufacturers launch products with user-replaceable batteries, across audio, e-readers, gaming handhelds, and more. Only time will tell whether most of those products are EU only, or whether the new European laws shape the nature of tech worldwide. It's likely that some product categories will move slower than others. Tech companies will have breathed a sigh of relief that wearables look likely to be exempt, but if wireless earbuds aren't carved out as well then there may be a scramble to adapt the miniature designs for easy replaceability. "The in-ear form factor demands extreme miniaturization, to fit the driver, antenna, processor, microphones and battery," notes a recent report from consultants Futuresource, going on to suggest that meeting the requirements will make earbuds both bigger and more expensive to manufacture. There also remains uncertainty about how some elements of the law will be interpreted. The law requires that user repairs be possible using "commercially available tools," which are "tools available on the market to all end-users." Right to Repair Europe's Alberico points out that this is a broad definition, likely to include a lot of tools not found in most houses, so there will likely be nothing to stop manufacturers requiring the sorts of less common screws that require dedicated electronics tool kits. There's also no strict definition of the "reasonable" price that manufacturers are required to set for spare parts. "That will likely take time -- and possibly litigation -- to clarify in practice," Alberico says. "But without fair access to affordable spare parts, repair will struggle to become the simplest and most attractive option for consumers." The big disappointment is that the separate phone and tablet legislation means we won't see any real changes there, so long as manufacturers make their batteries and devices durable. "This creates a false tradeoff between durability and repairability," Alberico says. "Robust, waterproof devices should not have to come at the expense of user-replaceable batteries. While the ecodesign legislation requirements meant an improvement in battery durability and replaceability, at Right to Repair Europe we'll continue to advocate for all products to be designed with user-replaceable batteries." Whether the EU will listen remains to be seen. Otherwise, the main product people seem to want to replace the battery in may remain one of the only ones where they can't.

Texas Adds Another Huge Solar Farm As ERCOT Grid Demand Soars

2 June 2026 at 02:00
Texas is adding another large solar project as ERCOT electricity demand rises. According to Electrek, Vesper Energy has secured $236 million in financing for its 201 MW Nazareth Solar farm in Swisher County, which will be capable of generating enough electricity for about 53,000 homes. The project is expected to begin construction in June 2026 and come online in fall 2027. From the report: Nazareth Solar will sit on more than 2,400 acres of private land and generate enough electricity to power around 53,000 homes annually. The project will neighbor Vesper's Hornet Solar (pictured above), another large solar farm the company developed. ERCOT faces growing demand from population growth, industrial expansion, and power-hungry data centers. And despite political attacks on renewables, solar continues getting built in this red state because it's one of the fastest and cheapest ways to add new electricity to the grid. Vesper says the project will bring new tax revenue to local schools, infrastructure, and emergency services, along with construction jobs and long-term operations roles. Participating landowners are also expected to receive long-term lease income from the solar farm.

Renewable Energy is Surging in Africa

31 May 2026 at 13:34
Almost a fifth of the earth's population lives in Africa. And Africa's next generation of power projects "is increasingly being built around solar and wind power and battery storage," reports the Associated Press, "as governments and investors shift away from coal and large hydropower dams in search of cheaper, faster and more reliable electricity." The shift is visible in a $1.5 billion energy agreement between China and Zambia announced in early May that includes three separate 300-megawatt projects spanning solar, wind and coal-fired power. While the inclusion of coal underscores the continent's continuing need for stable baseload electricity, African countries facing rising fuel import bills as a result of the Iran war, unreliable grids and growing industrial demand are increasingly turning to renewable energy projects that can be deployed faster and more cheaply than traditional plants. Of the 322 energy projects announced across Africa in 2025, 173 were solar projects, followed by hydropower at 46, wind at 34, gas at 22 and hybrid energy projects at 14, according to the energy research firm Electron Intelligence... Utility-scale solar power costs have dropped by nearly 90% globally since 2010, while onshore wind costs have fallen around 70%, making renewables the cheapest source of new electricity generation in many African markets... Much of the growth is through distributed solar and battery systems installed directly in mines, factories, telecom towers and homes. "Most official statistics still measure the energy transition the old way, by counting megawatts connected to national grids," [said Matt Tilleard, CEO of CrossBoundary Energy, which invests in renewable energy in Africa]. "But solar and batteries don't need central utilities." Data from the Africa Solar Industry Association shows 23.4 gigawatts of operational solar projects had been tracked across Africa by the end of 2025. But Chinese export figures indicate 58.1 gigawatts of solar panels have been shipped to African countries since 2017, suggesting solar adoption may be growing far faster than official figures capture. Investor Tilleard says "Renewable energy is now unequivocally the fastest, cheapest, and most bankable way to connect people, companies and economies to the megawatts they need to grow." And the article also includes this quote from Mugwe Manga, climate finance lead at FSD Kenya. "Africa is not on the periphery of the global energy transition, it is sitting at its center. The continent holds the world's best renewable resources, and the economics have now decisively turned in favor of clean energy."

US Aims to Give Cold War Plutonium to Startups For Nuclear Fuel

30 May 2026 at 06:34
The Trump administration is planning to provide Cold War-era plutonium from dismantled nuclear warheads to nuclear startups that want to convert it into reactor fuel, arguing it could help address a looming fuel shortage for advanced reactors. Critics warn the idea raises serious nonproliferation, security, cost, and technical concerns. The New York Times reports: The plan has generated debate and some unease among nonproliferation experts. If finalized, it would mark the first time the U.S. government has made weapons-grade plutonium available to private companies. The Energy Department has more than 50 tons of surplus plutonium left over from nuclear weapons programs, and the agency had previously been planning to dilute much of that material and bury it. Some of the nuclear start-ups trying to obtain that plutonium say that transforming the waste into fuel is a better way to dispose of it. On Tuesday, the Energy Department said that it had selected five companies to enter into "advanced negotiations" to potentially receive some surplus plutonium. That includes Oklo, a California-based nuclear power company, which plans to partner with Newcleo, a European developer of advanced nuclear reactors. Using plutonium for fuel, Oklo and Newcleo said, could solve a looming problem: Energy firms want to build a new wave of nuclear reactors, but the United States can't yet make enough conventional fuel from uranium to supply the plants. Harvesting old plutonium stockpiles could provide a short-term fix. "A lack of fuel is one of the biggest choke points in expanding nuclear power right now," said Jacob DeWitte, the chief executive of Oklo, which is developing a novel type of small reactor intended to run on plutonium. "This will help us get more nuclear power online faster." [...] The plan is not yet final, and companies will still have to negotiate with the federal government over how to secure and transfer the plutonium. In addition to Oklo, the Energy Department said it had also selected four other companies -- Standard Nuclear, Exodys Energy, SHINE Technologies and Flibe Energy -- to enter into advanced negotiations to receive the material under its Surplus Plutonium Utilization Program, which was established last year. The program "is anticipated to help companies unlock the next level of private funding to broaden domestic nuclear fuel supplies, spur innovation on American recycling technologies, and unlock private sector funding to fuel the nation's nuclear renaissance," said Michael Goff, the principal deputy assistant secretary of nuclear energy, in a statement.

MIT Researchers Develop a Low-Cost Technique To Get Lithium Out of Rocks

28 May 2026 at 22:30
An anonymous reader quotes a report from MIT News: Currently, lithium hard rock extraction involves baking the rock at over 1,000 Celsius and chemically leaching it to extract lithium. The rest of the rock is discarded. Now, a team of researchers from MIT and elsewhere has developed a low-temperature process for extracting battery-grade lithium from the most common type of lithium-bearing mineral. The process uses a liquid reagent to dissolve the rock into the useful forms of its constituent parts: not just battery-ready lithium salts, but also smelter-grade alumina and cement-ready silica. After the minerals are extracted, the solvent and reagent can be recovered and used again so waste levels approach zero. The researchers estimate the closed-loop process is half the cost of traditional lithium hard rock extraction and could make it cost-competitive with extracting lithium from brine water. "We believe this approach is the lowest-energy, lowest-cost way of getting lithium not only out of hard rock, but period," says Yet-Ming Chiang, MIT's Kyocera Professor of Materials Science and Engineering. "That's what's motivating us to scale this. It will enable the energy transition through batteries that use lithium. This was one of the goals of The Climate Project at MIT -- to work on projects that, within a short number of years, could transition from the lab to commercialization and impact." A paper describing the process has been published in the journal Science.

Wind and Solar Generated More Power Than Gas Globally in April

24 May 2026 at 11:34
Last month saw a world first, reports Electrek. Wind and solar generated more power globally than gas: According to new analysis from independent energy think tank Ember, wind and solar produced 22% of the world's electricity in April 2026, compared to 20% from gas. Together, the two renewable sources generated a record 531 terawatt-hours (TWh) of electricity during the month, 54 TWh more than gas plants generated globally, at 477 TWh... Five years ago, in April 2021, gas generation was almost identical to today's level at 476 TWh. But back then, wind and solar combined generated just 245 TWh β€” less than half of what they produced this April... Wind and solar generation increased across nearly every major market reporting April data... April tends to be the strongest month for this kind of milestone because spring weather in the Northern Hemisphere usually brings a combination of strong wind generation, rising solar output, and lower electricity demand between heating and cooling seasons. Still, the broader trend is clear. Ember's recent Global Electricity Review found that wind and solar met all global electricity demand growth in 2025. "Governments around the world are also ramping up renewable energy targets to reduce dependence on volatile fossil fuel imports..."

Some Datacenters Divert Power from Homes. Will It Drive Homeowners to Solar and Batteries?

16 May 2026 at 20:34
An anonymous reader shared this report from Electrek: A Nevada utility just told 49,000 Lake Tahoe residents that it's redirecting 75% of their electricity supply to data centers, and they have less than a year to find a new power source. It's one of the starkest examples yet of the AI boom's impact on everyday Americans... NV Energy needs the capacity for data centers being built by Google, Apple, and Microsoft around the Tahoe-Reno Industrial Center east of Reno, according to Fortune... Data centers drove half of all US electricity demand growth last year.... That dynamic β€” small residential customers losing out to massive industrial electricity buyers β€” is exactly what's driving the broader shift to distributed solar and storage. When the grid becomes unreliable or unaffordable because of data center demand, the homeowners who have solar panels and a battery in the garage are the ones with options. "The shift is measurable," they argue: Third-party ownership models (leases and power purchase agreements), which still qualify for the [U.S.] commercial investment tax credit through 2027, are projected to grow 25% in 2026 and capture up to 69% of residential installations, up from roughly 45% in 2025. Homeowners aren't waiting for incentives to come back β€” they're finding new ways to get solar on their roofs... [A] battery that can store cheap solar energy and deploy it during peak hours is increasingly essential. California utility customers alone are adding roughly 8,000 new home batteries per month β€” about 100 MW of new storage capacity. Municipal programs are accelerating the trend. Ann Arbor, Michigan, recently became the first US city to directly deploy solar and battery systems on 150 homes through its city-owned utility. Vermont's Green Mountain Power is offering home batteries at little to no upfront cost. These programs signal that utilities themselves recognize the value of distributed energy.

Microsoft's $1 Billion AI Data Center Will 'Switch Off Half of Kenya'

12 May 2026 at 14:00
Microsoft and G42's planned $1 billion AI data center in Kenya has stalled amid disagreements over power commitments, with President William Ruto saying the country would need to "switch off half the country" to support the project at full scale. Tom's Hardware reports: The project, announced in May 2024 during Ruto's visit to Washington, was supposed to bring a geothermal-powered data center to the Olkaria region in Kenya's Rift Valley. G42 was to lead construction, with the facility running Microsoft Azure in a new East Africa cloud region. The first phase targeted 100 megawatts of capacity and was expected to be operational by this year, with a long-term goal of scaling to 1 gigawatt. President Ruto isn't exaggerating about shutting off half the country's power. Kenya's total installed electricity capacity sits between 3,000 and 3,200 megawatts, and peak demand reached a record 2,444 megawatts in January, according to data from KenGen, the country's government-owned electricity producer. The full 1 gigawatt build would therefore have consumed roughly a third of the country's total capacity, and even the first 100 megawatts would have required a significant share of the Olkaria geothermal complex's output, which currently generates around 950MW across all its plants. John Tanui, principal secretary at Kenya's Ministry of Information, told Bloomberg that the project hasn't been withdrawn and that talks are continuing, adding that the "scale of the data center they [Microsoft] wanted to do still requires some structuring." A separate 60-megawatt project with local developer EcoCloud is also still under discussion. [...] Microsoft is spending $190 billion on capex in 2026, and the company adds approximately 1 gigawatt of data center capacity every three months globally. But power constraints are proving to be a universal bottleneck: nearly half of planned U.S. data center builds this year have been delayed or canceled due to shortages of electrical infrastructure.

Will Maryland's Utility Bills Increase $1.6B to Support Other States' Datacenters?

9 May 2026 at 17:34
To upgrade its grid for data centers, PJM Interconnection (which serves 13 states) plans to spend $22 billion β€” and charge nearly $2 billion of that to customers in Maryland, argues Maryland's Office of People's Counsel. The money "will be recovered in rates for decades" and "drive up Maryland customer bills by $1.6 billion over the next ten years alone," they said Friday, announcing an official complaint filed with America's Federal Energy Regulatory Commission. Extra demand is expected from Ohio, Pennsylvania, and Illinois "where demands driven by data centers are projected to grow substantially by 2036," they explain. But that means that Maryland customers "are subsidizing data center-driven transmission buildout by virtue of geographic proximity..." Tom's Hardware explains: That means an extra $823 million for residential (approx. $345 per customer), $146 million for commercial (approx. $673 per customer), and $629 million for industrial customers (approx. $15,074 per customer)... "Maryland customers have neither caused the need for these billions in new transmission projects nor will they meaningfully benefit from them," [according to Maryland People's Counsel David S. Lapp].... This is one of the biggest reasons why many AI hyperscalers are facing pushback from the communities where they intend to place their data centers. At the moment, around 69 jurisdictions have passed some sort of moratorium on projects like these, and a survey has shown that nearly half of Americans do not want a data center in their neighborhood. Debates around these projects are passionate, with a few cases turning violent and even resulting in shootings (thankfully, without any casualties), especially as many feel that the construction of these power-hungry assets is threatening their lifestyles and quality of life.

Major Homebuilder To Test Placing Mini Data Centers in Suburban Backyards

7 May 2026 at 06:00
NewtonsLaw writes: According to Realtor.com, a California startup called Span plans to partner with Nvidia, PulteGroup, and other homebuilders to equip new homes with mini-data centers, so as to relieve the need to build and power much larger traditional centers. The article states the company "can install 8,000 XFRA units about six times faster and at five times lower cost than the construction of a typical centralized 100 megawatt data center of the same size." Could this be the solution to at least some of the problems hindering the rollout of greater data-center capacity for AI systems? "One big reason the XFRA model works is that the average American home only uses about 40 percent of its electrical capacity," Span said. "As big data center developers struggle to find power sources and distribution capacity, XFRA uses capacity that's already available." The startup says they will launch a 100-home proof of concept within the year to see if the idea is viable.

Chinese Exports of Green Technologies Surged to Record Levels After Iran War Began

2 May 2026 at 22:34
"The war in Iran has sent oil-starved countries scrambling for fuel," CNN reported this week. And many of those countries now want renewable fuels, the article points out, "leaving them turning to the renewables king of the planet: China." Chinese exports of solar technology, batteries and electric vehicles all reached record highs in March, according to energy think tank Ember, a sign that the historic oil supply shock is accelerating the adoption of clean energy around the world... A Thursday report from Ember said China exported 68 gigawatts of solar technology in March, surpassing the previous record set in August by 50%. Fifty countries set new records for Chinese solar imports, with the most significant growth coming from emerging markets in Asia and Africa hit hardest by the energy crisis, according to the think tank. "Fossil shocks are boosting the solar surge," said Euan Graham, senior analyst at Ember, in the report. "Solar has already become the engine of the global economy, and now the current fossil fuel price shocks are taking it up a gear." Ember said exports of solar, batteries and EVs in total rose 70% in March year over year, according to Chinese customs data... China's battery exports reached $10 billion in March, with particularly high growth rates in the European Union, Australia and India, Ember said. Uncertainty over when the Strait of Hormuz will reopen has spurred deeper regional anxieties about energy securi"ty, helping to hasten the transition to clean energy, analysts said. The article notes how different countries are reacting to fuel Asian nations that depend on the Middle East for energy imports "are trying to mitigate fuel shortages by encouraging energy conservation and shortening work hours." The UK's Energy Secretary said this week that the country needed to reduce its reliance on gas for electricity. "As we face the second fossil fuel shock in less than 5 years, the lesson for our country is clear: The era of fossil fuel security is over, and the era of clean energy security must come of age." Pakistan "has been spared some of the impact from the war, since it began drastically importing cheap Chinese solar panels a few years ago. Using solar energy rather than costly oil imports is estimated to save the country billions of dollars each year." "According to the China Passenger Car Association, Chinese exports of electric vehicles and hybrids hit a record high in March, increasing 140% compared with the same period a year ago."

The $19B "Nuclear AI" Energy Startup That Couldn't Sign a Single Client

2 May 2026 at 16:34
"Nuclear AI startup" Fermi had hoped to build power plants generating 17 gigawatts of electricity, remembers Bloomberg, "three times the amount typically consumed by New York City." Hyperscalers could install their data centers on the site itself and tap directly into that power, which would come first from natural gas turbines and later from nuclear reactors. The pitch ticked so many boxes β€” artificial intelligence, nuclear energy, political connections β€” that some investors found it irresistible. Fermi went public in October worth more than $19 billion in market value, despite reporting no revenue or signed customers. Now, the startup's board has fired its top executive, Toby Neugebauer, after months of negotiations failed to secure a single client. Chief Financial Officer Miles Everson left as well... Fermi's stock, meanwhile, has tumbled 84% from its peak. The company's more than 5,000-acre site in the Texas panhandle β€” dubbed Project Matador, or the President Donald J. Trump Advanced Energy and Intelligence Campus β€” remains mostly unfinished. And some analysts see a cautionary tale of the market's AI enthusiasm running ahead of reality, with investors betting on companies whose grand projects may never get built... The idea of giving data centers their own, dedicated power supply not dependent on the grid may sound tempting, but former US Department of Energy official Jigar Shah said banks don't want to finance it. The grid, drawing power from many sources, is more reliable than a handful of expensive, on-site plants, he said. He considers Fermi a failure "of monumental proportions" and says similar, off-grid data center projects elsewhere deserve more skepticism than they've received... "We're allowing these types of projects to continue to be viewed as viable when they most certainly are not," said Shah, who ran the department's Loan Programs Office during the Biden administration.... "It was a piece of dirt with a dream," an investor who visited the site in February told the short sellers, Fuzzy Panda Research.

Belgium Plans To Nationalize Nuclear Power Plants

1 May 2026 at 02:00
Belgium plans to buy its seven aging nuclear reactors from French power giant Engie in a "full takeover" aimed at securing domestic energy supplies, extending reactor operations, and developing new nuclear capacity. "The move would also mean suspending plans to decommission nuclear operations in Belgium," reports the BBC. From the report: The move would reverse the phase-out of nuclear energy legislation approved in the early 2000s amid safety concerns prohibiting the building of new nuclear power plants and limiting the operating lifetimes of existing ones to 40 years. Only two of Belgium's seven nuclear reactors are operational - located at plants in Doel and in Tihange - and their operating licenses were recently extended until 2035. The other five reactors were shut between 2022 and 2025 and plans to dismantle them will now be suspended. Engie and the government said they aim to reach an agreement on the takeover of the nuclear stations by October 1st. In a joint statement with Engie, the Belgian government said the move also highlights its aim to extend operations of existing nuclear reactors and to develop "new nuclear capacity" in Belgium. "By doing so, the Belgian Government is taking responsibility for Belgium's long-term energy future, with the objective of building a financially and economically viable activity that supports security of supply, climate objectives, industrial resilience and socio-economic prosperity," the statement adds.

Trump Administration Will Pay More Energy Firms to Cancel Wind Farms

28 April 2026 at 02:00
The Trump administration says it will reimburse energy companies $885 million to cancel two planned offshore wind farms, with the firms in turn agreeing to put money into oil and gas projects instead. "The deals are modeled after a similar agreement last month with the French energy giant TotalEnergies," notes the New York Times. "TotalEnergies forfeited its leases for two wind projects planned off the coasts of New York and North Carolina, while committing to a range of fossil-fuel investments." From the report: [...] The first new agreement affects Bluepoint Wind, a wind farm in the early stages of development off New York and New Jersey. The project was proposed by Global Infrastructure Partners, a part of asset manager BlackRock, and Ocean Winds, which is itself a joint venture between Engie and EDP Renewables, two European clean-energy firms. The second deal would cancel Golden State Wind, another early-stage venture off California's central coast. Golden State Wind is a 50-50 partnership between the developers Ocean Winds and Reventus Power. Both Bluepoint Wind and Golden State Wind agreed not to pursue any new offshore wind projects in the United States, although that pledge would not necessarily apply to the companies behind the ventures. Ocean Winds has also been developing another giant wind farm known as SouthCoast Wind, off Martha's Vineyard, Mass., that is much further along in the planning and permitting process. That project is not affected by Monday's announcement, although it has essentially been paused since Mr. Trump took office last year. [...] It is also unclear how much the companies will actually invest in new fossil fuel infrastructure. In documents released this month, Interior revealed that it would count investments that TotalEnergies made before the deal toward its pledge, raising questions over whether the company had any obligations to make additional investments.

40 Years After the Chernobyl Disaster, More Countries Are Turning To Nuclear Power

26 April 2026 at 02:34
An anonymous reader shared this report from the Associated Press: The 1986 Chernobyl disaster fueled global fears about nuclear power and slowed its development in Europe and elsewhere. Four decades later, however, there's a revival around the world, a trend that has been given a big boost by war in the Middle East. Over 400 nuclear reactors are operational in 31 countries, while about 70 more are under construction. Nuclear power accounts for producing about 10% of the world's electricity, equivalent to about a quarter of all sources of low-carbon power. Nuclear reactors have seen steady improvements, adding more safety features and making them cheaper to build and operate. While Chernobyl and the 2011 Fukushima nuclear disaster in Japan diminished the appetite for such power sources, it was clear years ago that there probably would be a revival, said Fatih Birol, executive director of the International Energy Agency. With the war in the Middle East, "I am 100% sure nuclear is coming back," he added... The United States is the world's largest producer of nuclear power, with 94 operational reactors accounting for about 30% of global generation of nuclear electricity. And it is increasing efforts to develop nuclear energy capacity with a goal to quadruple it by 2050... China operates 61 nuclear reactors and is leading the world in building new units, with nearly 40 under construction with a goal to surpass the U.S. and become the global leader in nuclear capacity. European Commission chief Ursula von der Leyen has acknowledged that it was Europe's "strategic mistake" to cut nuclear energy and outlined new initiatives to encourage building power plants. [In 1990, nuclear energy accounted for roughly a third of Europe's electricity, the article points out, but it's now only about 15%.] Russia, meanwhile, has taken a strong lead in exporting its nuclear know-how, building 20 reactors worldwide... Japan has restarted 15 reactors after reviewing the lessons of the earthquake and tsunami that damaged the Fukushima plant, and 10 more are in the process of getting approval to restart. South Africa has the only nuclear power plant on the African continent, although Russia is building one in Egypt, and several other African nations are exploring the technology... With 57 reactors at 19 plants, France relies on nuclear power for nearly 70% of its electricity. The article includes an interactive graphic that shows the growth in the world's nuclear capacity slowing down soon after the 1986 Chernobyl meltdown β€” with that capacity broken down by country. But it's still increased by roughly 50%. Even Ukraine β€” the site of the accident β€” now "still relies heavily on nuclear plants to generate about half of its electricity," the article points out. But Germany "switched off its last three nuclear reactors in 2023."

New Gas-Powered Data Centers Could Emit More Greenhouse Gases Than Entire Nations

23 April 2026 at 22:30
An anonymous reader quotes a report from Wired: New gas projects linked to just 11 data center campuses around the US have the potential to create more greenhouse gases than the country of Morocco emitted in 2024. Emissions estimates from air permit documents examined by WIRED show that these natural gas projects -- which are being built to power data centers to serve some of the US's most powerful AI companies, including OpenAI, Meta, Microsoft, and xAI -- have the potential to emit more than 129 million tons of greenhouse gases per year. As tech companies race to secure massive power deals to build out hundreds of data centers across the country, these projects represent just the tip of the iceberg when it comes to the potential climate cost of the AI boom. The infrastructure on this list of large natural gas projects reviewed by WIRED is being developed to largely bypass the grid and provide power solely for data centers, a trend known as behind-the-meter power. As data center developers face long waits for connections to traditional utilities, and amid mounting public resistance to the possibility of higher energy bills, making their own power is becoming an increasingly popular option. These projects have either been announced or are under construction, with companies already submitting air permit application materials with state agencies. [...] The emissions projections for the xAI and Microsoft projects, and all the others on WIRED's list, were pulled directly from publicly-available air permit documents in state databases as well as public air permit materials collected by both Cleanview and Oil and Gas Watch, a database maintained by the Environmental Integrity Project, an environmental enforcement nonprofit. Actual greenhouse gas emissions from power plants are usually lower than what's on their air permits. Air permit modeling is based on the scenario of a power plant constantly running at full capacity. That's rarely the reality for grid-connected power plants, as turbines go offline for maintenance or adjust to the ebbs and flows of customer demand. "Permitted emission numbers represent a theoretical, conservative scenario, not the actual projected emissions," Alex Schott, the director of communications at Williams Companies, an oil and gas company that is building out three behind-the-meter power plants in Ohio for Meta, told WIRED in an email. Internal modeling done by the company, Schott added, shows that actual emissions could be "potentially two-thirds less than what's on paper." The projections involved, however, are still substantial. Even if the actual emissions from these power plants end up being half of the emissions numbers on the permits, they still could create more greenhouse gas emissions than the country of Norway emitted in 2024. This number is, according to the EPA, equivalent to the emissions from more than 153 average-sized natural gas plants. (WIRED's analysis does not include emissions from backup generators and turbines on the data center campuses themselves, which create smaller amounts of emissions.) Energy researcher Jon Koomey says the data center boom has created a shortage of the most efficient gas turbines, pushing some developers toward less efficient models that would need to run longer and produce more emissions. "[Data center operators'] belief is that the value being delivered by the servers is much, much more than the cost of running these inefficient power plants all the time," he said. Michael Thomas, the founder of clean energy research firm Cleanview, has been tracking gas permits for data centers across the country. He calls behind-the-meter power "a crazy acceleration of emissions." He added: "It's almost like we thought we were on the downside of the Industrial Revolution, retiring coal and gas, and now we have a new hump where we're going to rise. That terrifies me in a lot of ways."

Global Growth In Solar 'the Largest Ever Observed For Any Source'

21 April 2026 at 11:00
The IEA says 2025 marked a turning point for global energy, with solar posting the largest growth ever seen for any energy source and helping carbon-free power outpace rising demand. The trend led the agency to declare that the world has entered the "Age of Electricity." Ars Technica reports: The IEA report covers energy use, including the electrical grid, transportation, home heating, and other forms of consumption. As such, it can track how some of those uses are shifting, as electric vehicles displace some gasoline use and heat pumps replace gas and oil heating. It also saw a more global trend: The demand for electricity grew at twice the rate of overall energy demand. All of these went into the conclusion that we're starting the Age of Electricity. In terms of specifics, the IEA saw electric vehicle demand rise by nearly 40 percent, with electric car sales being a quarter of the total of cars sold last year. While that's having a measurable effect on electricity demand, it remains relatively small at the moment. It's almost certain to be contributing to the size of the rise in oil use last year: 0.7 percent. In absolute terms, that's less than half the average rise of the previous decade. [...] When it comes to supplying electrons for those alternatives, the central story is solar power. "The absolute increase of solar PV generation in 2025 is the largest ever observed for any source," the IEA says, "excluding years marked by rebounds from global economic shocks such as COVID-19." In other words, with nothing in particular driving the energy markets in 2025, Solar's growth was unprecedented. On its own, its growth covered a quarter of the rising demand for all forms of energy. If you limit it to electricity, increased solar production covered over two-thirds of the increased demand. Overall, solar generated over 2,700 terawatt-hours last year, more than double its output from three years earlier. It now accounts for over 8 percent of the world's total electricity production. Thirty individual countries installed at least a gigawatt of solar last year, and it is now the single largest grid source by capacity (though other sources still outproduce it at the moment).

Is the Iran War Driving a Surge of Interest in Electric Cars?

19 April 2026 at 14:34
In October and through November, America's EV sales reached their lowest point since 2022 after government subsidies expired, remembers Time. "But first-quarter data for 2026 shows that used EV sales were 12% higher than the same time last year and 17% higher than the previous quarter. "One factor likely helping push buyers toward these cars is high gas prices, which recently topped $4.00 a gallon for the first time in four years," they write β€” but it's not just in the U.S. Instead, they argue the U.S.-Iran conflict "is driving a global surge of interest in electric vehicles..." In the U.K., electric car sales reached a record high, with 86,120 vehicles sold in March... The French online used-car retailer Aramisauto reported its share of EV sales nearly doubled from February 16 to March 9, rising to 12.7% from 6.5%, while sales of fueled models dropped to 28% of sales from 34%, and sales of diesel models dropped to 10% from 14%. Germany's largest online car market, mobile.de, told Reuters that the share of EV searches on its website has tripled since the start of March β€” from 12% to 36%, with car dealers receiving 66% more enquiries for used EVs than in February. South Korea reported that registrations for electric vehicles more than doubled in March compared to the prior year, due in part to rising fuel prices and government subsidies... In New Zealand, more than 1,000 EVs were registered in the week that ended on March 22, close to double the week before, making it the country's biggest week for electric vehicle registrations since the end of 2023, according to the country's Transport Minister, Chris Bishop. In America, Bloomberg also reports 605 high-speed EV charging stations switched on in just the first three months of 2025, "a 34% increase over the year-earlier period," according to their analysis of federal data. A data platform focused on EV infrastructure tells Bloomberg that speedier and more reliable chargers are convincing more drivers to go electric and use public plugs.
