One Company's Plan to Sink Nuclear Reactors Deep Underground (ieee.org) 113

Long-time Slashdot reader jenningsthecat shared this article from IEEE Spectrum: By dropping a nuclear reactor 1.6 kilometers (1 mile) underground, Deep Fission aims to use the weight of a billion tons of rock and water as a natural containment system comparable to concrete domes and cooling towers. With the fission reaction occurring far below the surface, steam can safely circulate in a closed loop to generate power.

The California-based startup announced in October that prospective customers had signed non-binding letters of intent for 12.5 gigawatts of power involving data center developers, industrial parks, and other (mostly undisclosed) strategic partners, with initial sites under consideration in Kansas, Texas, and Utah... The company says its modular approach allows multiple 15-megawatt reactors to be clustered on a single site: A block of 10 would total 150 MW, and Deep Fission claims that larger groupings could scale to 1.5 GW. Deep Fission claims that using geological depth as containment could make nuclear energy cheaper, safer, and deployable in months at a fraction of a conventional plant's footprint...

The company aims to finalize its reactor design and confirm the pilot site in the coming months. [Company founder Liz] Muller says the plan is to drill the borehole, lower the canister, load the fuel, and bring the reactor to criticality underground in 2026. Sites in Utah, Texas, and Kansas are among the leading candidates for the first commercial-scale projects, which could begin construction in 2027 or 2028, depending on the speed of DOE and NRC approvals. Deep Fission expects to start manufacturing components for the first unit in 2026 and does not anticipate major bottlenecks aside from typical long-lead items.

In short "The same oil and gas drilling techniques that reliably reach kilometer-deep wells can be adapted to host nuclear reactors..." the article points out. Their design would also streamline construction, since "Locating the reactors under a deep water column subjects them to roughly 160 atmospheres of pressure — the same conditions maintained inside a conventional nuclear reactor — which forms a natural seal to keep any radioactive coolant or steam contained at depth, preventing leaks from reaching the surface."

Other interesting points from the article:
  • They plan on operating and controlling the reactor remotely from the surface.
  • Company founder Muller says if an earthquake ever disrupted the site, "you seal it off at the bottom of the borehole, plug up the borehole, and you have your waste in safe disposal."
  • For waste management, the company "is eyeing deep geological disposal in the very borehole systems they deploy for their reactors."
  • "The company claims it can cut overall costs by 70 to 80 percent compared with full-scale nuclear plants."

"Among its competition are projects like TerraPower's Natrium, notes the tech news site Hackaday, saying TerraPower's fast neutron reactors "are already under construction and offer much more power per reactor, along with Natrium in particular also providing built-in grid-level storage.

"One thing is definitely for certain..." they add. "The commercial power sector in the US has stopped being mind-numbingly boring."

Could High-Speed Trains Shorten US Travel Times While Reducing Emissions? (cnn.com) 222

With some animated graphics, CNN "reimagined" what three of America's busiest air and road travel routes would look like with high-speed trains, for "a glimpse into a faster, more connected future." The journey from New York City to Chicago could take just over six hours by high-speed train at an average speed of 160 mph, cutting travel time by more than 13 hours compared with the current Amtrak route... The journey from San Francisco to Los Angeles could be completed in under three hours by high-speed train... The journey from Atlanta to Orlando could be completed in under three hours by high-speed train that reaches 160 mph, cutting travel time by over half compared with driving...

While high-speed rail remains a fantasy in the United States, it is already hugely successful across the globe. Passengers take 3 billion trips annually on more than 40,000 miles of modern high-speed railway across the globe, according to the International Union of Railways. China is home to the world's largest high-speed rail network. The 809-mile train journey from Beijing to Shanghai takes just four and a half hours... In Europe, France's Train a Grand Vitesse (TGV) is recognized as a pioneer of high-speed rail technology. Spain soon followed France's success and now hosts Europe's most extensive high-speed rail network...

[T]rain travel contributes relatively less pollution of every type, said Jacob Mason of the Institute for Transportation and Development Policy, from burning less gasoline to making less noise than cars and taking up less space than freeways. The reduction in greenhouse gas emissions is staggering: Per kilometer traveled, the average car or a short-haul flight each emit more than 30 times the CO2 equivalent than Eurostar high-speed trains, according to data from the UK government.

Engineers are Building the Hottest Geothermal Power Plant on Earth - Next to a US Volcano (yahoo.com) 37

"On the slopes of an Oregon volcano, engineers are building the hottest geothermal power plant on Earth," reports the Washington Post: The plant will tap into the infernal energy of Newberry Volcano, "one of the largest and most hazardous active volcanoes in the United States," according to the U.S. Geological Survey. It has already reached temperatures of 629 degrees Fahrenheit, making it one of the hottest geothermal sites in the world, and next year it will start selling electricity to nearby homes and businesses. But the start-up behind the project, Mazama Energy, wants to crank the temperature even higher — north of 750 degrees — and become the first to make electricity from what industry insiders call "superhot rock." Enthusiasts say that could usher in a new era of geothermal power, transforming the always-on clean energy source from a minor player to a major force in the world's electricity systems.

"Geothermal has been mostly inconsequential," said Vinod Khosla, a venture capitalist and one of Mazama Energy's biggest financial backers. "To do consequential geothermal that matters at the scale of tens or hundreds of gigawatts for the country, and many times that globally, you really need to solve these high temperatures." Today, geothermal produces less than 1 percent of the world's electricity. But tapping into superhot rock, along with other technological advances, could boost that share to 8 percent by 2050, according to the International Energy Agency (IEA). Geothermal using superhot temperatures could theoretically generate 150 times more electricity than the world uses, according to the IEA. "We believe this is the most direct path to driving down the cost of geothermal and making it possible across the globe," said Terra Rogers, program director for superhot rock geothermal at the Clean Air Task Force, an environmentalist think tank. "The [technological] gaps are within reason. These are engineering iterations, not breakthroughs."

The Newberry Volcano project combines two big trends that could make geothermal energy cheaper and more widely available. First, Mazama Energy is bringing its own water to the volcano, using a method called "enhanced geothermal energy"... [O]ver the past few decades, pioneering projects have started to make energy from hot dry rocks by cracking the stone and pumping in water to make steam, borrowing fracking techniques developed by the oil and gas industry... The Newberry project also taps into hotter rock than any previous enhanced geothermal project. But even Newberry's 629 degrees fall short of the superhot threshold of 705 degrees or above. At that temperature, and under a lot of pressure, water becomes "supercritical" and starts acting like something between a liquid and a gas. Supercritical water holds lots of heat like a liquid, but it flows with the ease of a gas — combining the best of both worlds for generating electricity... [Sriram Vasantharajan, Mazama's CEO] said Mazama will dig new wells to reach temperatures above 750 degrees next year. Alongside an active volcano, the company expects to hit that temperature less than three miles beneath the surface. But elsewhere, geothermal developers might have to dig as deep as 12 miles.

While Mazama plans to generate 15 megawatts of electricity next year, it hopes to eventually increase that to 200 megawatts. (And the company's CEO said it could theoretically generate five gigawatts of power.)

But more importantly, successful projects "motivate other players to get into the market," according to a senior geothermal research analyst at energy consultancy Wood Mackenzie, who predicted "a ripple effect," to the Washington Post where "we'll start seeing more companies get the financial support to kick off their own pilots."

Tiny 'Micro-Robots' in your Bloodstream Could Deliver Drugs with Greater Precision (msn.com) 30

The Washington Post reports: Scientists in Switzerland have created a robot the size of a grain of sand that is controlled by magnets and can deliver drugs to a precise location in the human body, a breakthrough aimed at reducing the severe side effects that stop many medicines from advancing in clinical trials... "I think surgeons are going to look at this," [said Bradley J. Nelson, an author of the paper in Science describing the discovery and a professor of robotics and intelligent systems at ETH Zurich]. I'm sure they're going to have a lot of ideas on how to use" the microrobot. The capsule, which is steered by magnets, might also be useful in treating aneurysms, very aggressive brain cancers, and abnormal connections between arteries and veins known as arteriovenous malformations, Nelson said. The capsules have been tested successfully in pigs, which have similar vasculature to humans, and in silicone models of the blood vessels in humans and animals... Nelson said drug-ferrying microrobots of this kind may be three to five years from being tested in clinical trials. The problem faced by many drugs under development is that they spread throughout the body instead of going only to the area in need... A major cause of side effects in patients is medications traveling to parts of the body that don't need them. The capsules developed in Switzerland, however, can be maneuvered into precise locations by a surgeon using a tool not that different from a PlayStation controller. The navigation system involves six electromagnetic coils positioned around the patient, each about 8 to 10 inches in diameter... The capsules are made of materials that have been found safe for people in other medical tools...

When the capsule reaches its destination in the body, "we can trigger the capsule to dissolve," Nelson said.

Tech Company CTO and Others Indicted For Exporting Nvidia Chips To China (arstechnica.com) 11

An anonymous reader quotes a report from Ars Technica: The US crackdown on chip exports to China has continued with the arrests of four people accused of a conspiracy to illegally export Nvidia chips. Two US citizens and two nationals of the People's Republic of China (PRC), all of whom live in the US, were charged in an indictment (PDF) unsealed on Wednesday in US District Court for the Middle District of Florida. The indictment alleges a scheme to send Nvidia "GPUs to China by falsifying paperwork, creating fake contracts, and misleading US authorities," John Eisenberg, assistant attorney general for the Justice Department's National Security Division, said in a press release yesterday.

The four arrestees are Hon Ning Ho (aka Mathew Ho), a US citizen who was born in Hong Kong and lives in Tampa, Florida; Brian Curtis Raymond, a US citizen who lives in Huntsville, Alabama; Cham Li (aka Tony Li), a PRC national who lives in San Leandro, California; and Jing Chen (aka Harry Chen), a PRC national who lives in Tampa on an F-1 non-immigrant student visa. The suspects face a raft of charges for conspiracy to violate the Export Control Reform Act of 2018, smuggling, and money laundering. They could serve many decades in prison if convicted and given the maximum sentences and forfeit their financial gains. The indictment says that Chinese companies paid the conspirators nearly $3.9 million.
One of the suspects was briefly the CTO of Corvex, a Virginia-based AI cloud computing company that is planning to go public. Corvex told CNBC yesterday that it "had no part in the activities cited in the Department of Justice's indictment," and that "the person in question is not an employee of Corvex. Previously a consultant to the company, he was transitioning into an employee role but that offer has been rescinded."

Meta Enters Power Trading To Support Its AI Energy Needs (bloomberg.com) 12

Meta is venturing into the complex world of electricity trading, betting it can accelerate the construction of new US power plants that are vital to its AI ambitions. From a report: The foray into power trading comes after Meta heard from investors and plant developers that too few power buyers were willing to make the early, long-term commitments required to spur investment, according to Urvi Parekh, the company's head of global energy. Trading electricity will give the company the flexibility to enter more of those longer contracts.

Plant developers "want to know that the consumers of power are willing to put skin in the game," Parekh said in an interview. "Without Meta taking a more active voice in the need to expand the amount of power that's on the system, it's not happening as quickly as we would like."

HP and Dell Disable HEVC Support Built Into Their Laptops' CPUs (arstechnica.com) 105

An anonymous reader quotes a report from Ars Technica: Some Dell and HP laptop owners have been befuddled by their machines' inability to play HEVC/H.265 content in web browsers, despite their machines' processors having integrated decoding support. Laptops with sixth-generation Intel Core and later processors have built-in hardware support for HEVC decoding and encoding. AMD has made laptop chips supporting the codec since 2015. However, both Dell and HP have disabled this feature on some of their popular business notebooks.

HP discloses this in the data sheets for its affected laptops, which include the HP ProBook 460 G11 [PDF], ProBook 465 G11 [PDF], and EliteBook 665 G11 [PDF]. "Hardware acceleration for CODEC H.265/HEVC (High Efficiency Video Coding) is disabled on this platform," the note reads. Despite this notice, it can still be jarring to see a modern laptop's web browser eternally load videos that play easily in media players.
HP and Dell didn't explain why the companies disabled HEVC hardware decoding on their laptops' processors.

A statement from an HP spokesperson said: "In 2024, HP disabled the HEVC (H.265) codec hardware on select devices, including the 600 Series G11, 400 Series G11, and 200 Series G9 products. Customers requiring the ability to encode or decode HEVC content on one of the impacted models can utilize licensed third-party software solutions that include HEVC support. Check with your preferred video player for HEVC software support."

Dell's media relations team shared a similar statement: "HEVC video playback is available on Dell's premium systems and in select standard models equipped with hardware or software, such as integrated 4K displays, discrete graphics cards, Dolby Vision, or Cyberlink BluRay software. On other standard and base systems, HEVC playback is not included, but users can access HEVC content by purchasing an affordable third-party app from the Microsoft Store. For the best experience with high-resolution content, customers are encouraged to select systems designed for 4K or high-performance needs."

Apple N1 Wi-Fi Chip Improves On Older Broadcom Chips In Every Way (arstechnica.com) 34

An anonymous reader quotes a report from Ars Technica: This year's newest iPhones included one momentous change that marked a new phase in the evolution of Apple Silicon: the Apple N1, Apple's first in-house chip made to handle local wireless connections. The N1 supports Wi-Fi 7, Bluetooth 6, and the Thread smart home communication protocol, and it replaces the third-party wireless chips (mostly made by Broadcom) that Apple used in older iPhones. Apple claimed that the N1 would enable more reliable connectivity for local communication features like AirPlay and AirDrop but didn't say anything about how users could expect it to perform. But Ookla, the folks behind the SpeedTest app and website, have analyzed about five weeks' worth of users' testing data to get an idea of how the iPhone 17 lineup stacks up to the iPhone 16, as well as Android phones with Wi-Fi chips from Qualcomm, MediaTek, and others.

While the N1 isn't at the top of the charts, Ookla says Apple's Wi-Fi chip "delivered higher download and upload speeds on Wi-Fi compared to the iPhone 16 across every studied percentile and virtually every region." The median download speed for the iPhone 17 series was 329.56Mbps, compared to 236.46Mbps for the iPhone 16; the upload speed also jumped from 73.68Mbps to 103.26Mbps. Ookla noted that the N1's best performance seemed to improve scores most of all in the bottom 10th percentile of performance tests, "implying Apple's custom silicon lifts the floor more than the ceiling." The iPhone 17 also didn't top Ookla's global performance charts -- Ookla found that the Pixel 10 Pro series slightly edges out the iPhone 17 in download speed, while a Xiaomi 15T Pro with MediaTek Wi-Fi silicon featured better upload speeds.

More Than 60 US and Canadian Police Units Now Use Boston Dynamics' Robot Dog (msn.com) 39

Boston Dynamics' Spot robot is now deployed by more than 60 bomb squads and SWAT teams across the US and Canada. The 75-pound four-legged machine starts at around $100,000 and has been used in armed standoffs, hostage rescues and hazardous materials incidents since its commercial debut five years ago. The Massachusetts State Police operates two Spot units purchased in 2020 and 2022. Each cost about $250,000 including add-ons funded through state grants. Last year one of the robots helped corner a suspect who had taken his mother hostage at knifepoint in Hyannis. Houston operates three units and Las Vegas has one.

ICE recently spent around $78,000 on a similar robot from Canadian manufacturer Icor Technology that can also deploy smoke bombs. Civil liberties groups have raised concerns about normalizing militarized policing. The NYPD suspended its limited Spot program in 2021 after public backlash over cost and surveillance concerns before later reinstating it and purchasing two units. The Electronic Frontier Foundation says there should be state and federal laws providing guidance on appropriate use of such technology. About 2,000 Spot units now operate globally.

US Backs Three Mile Island Nuclear Restart With $1 Billion Loan To Constellation (cnbc.com) 74

An anonymous reader quotes a report from CNBC: The Trump administration will provide Constellation Energy with a $1 billion loan to restart the Crane Clean Energy Center nuclear plant in Pennsylvania, Department of Energy officials said Tuesday. Previously known as Three Mile Island Unit 1, the plant is expected to start generating power again in 2027. Constellation unveiled plans to rename and restart the reactor in Sept. 2024 through a power purchase agreement with Microsoft to support the tech company's data center demand in the region.

Three Mile Island Unit 1 ceased operations in 2019, one of a dozen reactors that closed in recent years as nuclear struggled to compete against cheap natural gas. It sits on the same site as Three Mile Island Unit 2, the reactor that partially melted down in 1979 in the worst nuclear accident in U.S. history. The loan would cover the majority to the project's estimated cost of $1.6 billion. The first advance to Constellation is expected in the first quarter of 2026, said Greg Beard, senior advisor to the Energy Department's Loan Programs Office, in a call with reporters. The loan comes with a guarantee from Constellation that it will protect taxpayer money, Beard said.

Report Claims That Apple Has Yet Again Put the Mac Pro 'On the Back Burner' (arstechnica.com) 22

An anonymous reader quotes a report from Ars Technica: Apple's Power Mac and Mac Pro towers used to be the company's primary workstations, but it has been years since they were updated with the same regularity as the MacBook Air or MacBook Pro. The Mac Pro has seen just four hardware updates in the last 15 years, and that's counting a 2012 refresh that was mostly identical to the 2010 version. Long-suffering Mac Pro buyers may have taken heart when Apple finally added an M2 Ultra processor to the tower in mid-2023, making it one of the very last Macs to switch from Intel to Apple Silicon -- surely this would mean that the computer would at least be updated once every year or two, like the Mac Studio has been? But Bloomberg's Mark Gurman says that Mac Pro buyers shouldn't get their hopes up for new hardware in 2026.

Gurman says that the tower is "on the back burner" at Apple and that the company is "focused on a new Mac Studio" for the next-generation M5 Ultra chip that is in the works. As we reported earlier this year, Apple doesn't have plans to design or release an M4 Ultra, and the Mac Studio refresh from this spring included an M3 Ultra alongside the M4 Max. Note that Gurman carefully stops short of saying we definitely won't see a Mac Pro update next year -- the emphasis on the Mac Studio merely "suggests the Mac Pro won't be updated in 2026 in a significant way," and internal sources tell him "Apple has largely written off the Mac Pro." The current Mac Pro does still use the M2 Ultra rather than the M3 Ultra, which indicates that Apple doesn't see the need to update its high-end desktop every time it releases a suitable chip. But all of Apple's other desktops -- the iMac, the Mac mini, and the Studio -- have skipped a silicon generation once since the M1 came out in 2020.

Valar Atomics Says It's the First Nuclear Startup To Achieve Criticality (wired.com) 48

An anonymous reader quotes a report from Wired: Startup Valar Atomics said on Monday that it achieved criticality -- an essential nuclear milestone -- with the help of one of the country's top nuclear laboratories. The El Segundo, California-based startup, which last week announced it had secured a $130 million funding round with backing from Palmer Luckey and Palantir CTO Shyam Sankar, claims that it is the first nuclear startup to create a critical fission reaction. It's also, more specifically, the first company in a special Department of Energy pilot program aiming to get at least three startups to criticality by July 4 of next year to announce it had achieved this reaction. The pilot program, which was formed following an executive order President Donald Trump signed in May, has upended US regulation of nuclear startups, allowing companies to reach new milestones like criticality at a rapid pace.

There's a difference between the type of criticality Valar reached this week -- what's known as cold criticality or zero-power criticality -- and what's needed to actually create nuclear power. Nuclear reactors use heat to create power, but in cold criticality, which is used to test a reactor's design and physics, the reaction isn't strong enough to create enough heat to make power. The reactor that reached criticality this week is not actually Valar's own model, but rather a blend of the startup's fuel and technology with key structural components provided by the Los Alamos National Laboratory, one of the DOE's research and development laboratories. The combination reactor builds off a separate fuel test performed last year at the laboratory, using fuel similar to what Valar's reactor will use.
"Zero power criticality is a reactor's first heartbeat, proof the physics holds," Valar founder Isaiah Taylor said in a statement. "This moment marks the dawn of a new era in American nuclear engineering, one defined by speed, scale, and private-sector execution with closer federal partnership."

Electric Vehicle Sales Are Booming In South America (reuters.com) 119

Chinese automakers are rapidly expanding across South America, boosted by the new Chinese-built Port of Chancay, aggressive pricing, local partnerships, and growing regional demand. Reuters reports: China has been ramping up sales since the opening last year of the Port of Chancay, north of Lima. The Chinese-built megaport has halved trans-Pacific shipping times just as Chinese manufacturers face rising barriers to entry in the United States and greater trade restrictions in Europe.

BYD, which makes EVs, plug-in hybrids and combustion engine cars, plans to open a fourth dealership in Lima by the end of this year, while Chery and Geely have more than a dozen in total in Peru. Chinese carmakers face a profit-destroying price war at home and a growing surplus of new cars rolling out of Chinese factory lines. Much of this excess is being shipped overseas to the Middle East, Central Asia and Latin America, according to global automotive analyst Felipe Munoz at JATO Dynamics.

The Chinese have "carved out space," across both electric and petrol-powered cars, said Martin Bresciani, president of Chile's automotive business chamber, CAVEM. "The Chinese have already demonstrated that they match global standards in quality." Chinese brands reached 29.6% of all new passenger car sales in Chile in the first quarter of this year. [...] Part of China's success has been partnering with trusted local importers to offer more affordable models tailored to regional tastes, according to seven dealerships Reuters spoke to in Peru, Chile, Uruguay and Argentina.

Some Americans Are Trying to Heat Their Homes With Bitcoin Mining (cnbc.com) 90

An anonymous reader shared this report from CNBC: [T]he computing power of crypto mining generates a lot of heat, most which just ends up vented into the air. According to digital assets brokerage, K33, the bitcoin mining industry generates about 100 TWh of heat annually — enough to heat all of Finland.This energy waste within a very energy-intense industry is leading entrepreneurs to look for ways to repurpose the heat for homes, offices, or other locations, especially in colder weather months.

During a frigid snap earlier this year, The New York Times reviewed HeatTrio, a $900 space heater that also doubles as a bitcoin mining rig. Others use the heat from their own in-home cryptocurrency mining to spread warmth throughout their house. "I've seen bitcoin rigs running quietly in attics, with the heat they generate rerouted through the home's ventilation system to offset heating costs. It's a clever use of what would otherwise be wasted energy," said Jill Ford, CEO of Bitford Digital, a sustainable bitcoin mining company based in Dallas... "Same price as heating the house, but the perk is that you are mining bitcoin," Ford said...

The crypto-heated future may be unfolding in the town of Challis, Idaho, where Cade Peterson's company, Softwarm, is repurposing bitcoin heat to ward off the winter. Several shops and businesses in town are experimenting with Softwarm's rigs to mine and heat. At TC Car, Truck and RV Wash, Peterson says, the owner was spending $25 a day to heat his wash bays to melt snow and warm up the water. "Traditional heaters would consume energy with no returns. They installed bitcoin miners and it produces more money in bitcoin than it costs to run," Peterson said. Meanwhile, an industrial concrete company is offsetting its $1,000 a month bill to heat its 2,500-gallon water tank by heating it with bitcoin. Peterson has heated his own home for two-and-a-half years using bitcoin mining equipment and believes that heat will power almost everything in the future. "You will go to Home Depot in a few years and buy a water heater with a data port on it and your water will be heated with bitcoin," Peterson said.

Derek Mohr, clinical associate professor at the University of Rochester Simon School of Business, remains skeptical. Bitcoin mining is so specialized now that a home computer, or even network of home computers, would have almost zero chance of being helpful in mining a block of bitcoin, according to Mohr, with mining farms use of specialized chips that are created to mine bitcoin much faster than a home computer... "The bitcoin heat devices I have seen appear to be simple space heaters that use your own electricity to heat the room..."
CNBC also spoke to Andrew Sobko, founder of Argentum AI (which is building a marketplace for sharing computing power), who says the idea makes the most sense in larger settings. "We're working with partners who are already redirecting compute heat into building heating systems and even agricultural greenhouse warming. That's where the economics and environmental benefits make real sense. Instead of trying to move the heat physically, you move the compute closer to where that heat provides value."

Are Data Centers Raising America's Electricity Prices? (cnbc.com) 71

Residential utility bills in America "rose 6% on average nationwide in August compared with the same period in the previous year," reports CNBC, citing statistics from the U.S. Energy Information Administration: The reasons for price increases are often complex and vary by region. But in at least three states with high concentrations of data centers, electric bills climbed much faster than the national average during that period. Prices, for example, surged by 13% in Virginia, 16% in Illinois and 12% in Ohio.

The tech companies and AI labs are building data centers that consume a gigawatt or more of electricity in some cases, equivalent to more than 800,000 homes, the size of a city essentially... "The techlash is real," said Abraham Silverman, who served as general counsel for New Jersey's public utility board from 2019 until 2023 under outgoing Democratic Gov. Phil Murphy. "Data centers aren't always great neighbors," said Silverman, now a researcher at Johns Hopkins University. "They tend to be loud, they can be dirty and there's a number of communities, particularly in places with really high concentrations of data centers, that just don't want more data centers..." [C]apacity prices get passed down to consumers in their utility bills, Silverman said. The data center load in PJM [America's largest grid, serving 13 states] is also impacting prices in states that are not industry leaders such as New Jersey, where prices jumped about 20% year over year...

There are other reasons for rising electricity prices, Silverman said. The aging electric grid needs upgrades at a time of broad inflation and the cost of building new transmission lines has gone up by double digits, he said. The utilities also point to rising demand from the expansion of domestic manufacturing and the broader electrification of the economy, such as electric vehicles and the adoption of electric heat pumps in some regions...

In other states, however, the relationship between rising electricity prices and data centers is less clear. Texas, for example, is second only to Virginia with more than 400 data centers. But prices in the Lone Star state increased about 4% year over year in August, lower than the national average. Texas operates its own grid, ERCOT, with a relatively fast process that can connect new electric supply to the grid in around three years, according to a February 2024 report from the Brattle Group. California, meanwhile, has the third most data centers in the nation and the second highest residential electricity prices, nearly 80% above the national average. But prices in the Golden State increased about 1% in August 2024 over the prior year period, far below the average hike nationwide. One of the reasons California's electricity rates are so much higher than most of the country is the costs associated with preventing wildfires.

Solar and Wind are Covering All New Power Demand in 2025 (electrek.co) 88

An anonymous reader shared this report from Electrek: Solar and wind are growing fast enough to meet all new electricity demand worldwide for the first three quarters of 2025, according to new data from energy think tank Ember.

The group now expects fossil power to stay flat for the full year, marking the first time since the pandemic that fossil generation won't increase. Solar and wind aren't just expanding; they're outpacing global electricity demand itself. Solar generation jumped 498 TWh (+31%) compared to the same period last year, already topping all the solar power produced in 2024. Wind added another 137 TWh (+7.6%). Together, they supplied 635 TWh of new clean electricity, beating out the 603 TWh rise in global demand (+2.7%). That lifted solar and wind to 17.6% of global electricity in the first three quarters of the year, up from 15.2% year-over-year. That brought the total share of renewables in global electricity -solar, wind, hydro, bioenergy, and geothermal — to 43%. Fossil fuels slid to 57.1%, down from 58.7%.

For the first time in 2025, renewables collectively generated more electricity than coal. And fossil generation as a whole has stalled. Fossil output slipped slightly by 0.1% (-17 TWh) through the end of Q3. Ember expects no fossil-fuel growth for the full year, driven by clean power growth outpacing demand.

EV Sales Are Still Rising. They Have Not Slumped (electrek.co) 126

"Media headlines suggesting some slowdown in EV sales are simply incorrect," writes the site Electrek, "and leave out the bigger picture that gas car sales actually are dropping..." Over the course of the last two years or so, sales of battery electric vehicles, while continuing to grow, have posted lower year-over-year percentage growth rates than they had in years prior. EV sales used to grow at 50%+ per year, but for the last couple years, they have grown closer to ~25% per year. This alone is not particularly remarkable — it is inevitable that any growing product or category will show slower percentage growth rates as sales rise, particularly one that has been growing at such a fast rate for so long. In some recent years, we had even seen year-over-year doublings in EV market share (though one of those was 2020->2021, which was anomalous). To expect improvement at that level perpetually would be close to impossible — after 3 years of doubling market share from 2023's 18% number, EVs would account for more than 100% of the global automotive market, which cannot happen...

We have seen a global EV sales growth rate of 23% in the first 10 months of this year, according to a report just released by Rho Motion (recently acquired by Benchmark Mineral Intelligence). That includes a +32% bump in Europe, +22% bump in China, +4% in North America, and a big +48% bump in the "rest of the world." Notably, this 23% global growth rate is higher than last year's YTD growth rate, which was 22% at this time...

In covering these trends, some journalists have attempted to use the less-wrong phrase "slower growth," showing that EV sales are still growing, but at a lower percentage change than previously seen. But for the first ten months of this year, that isn't true — EV sales are up more in 2025 than in 2024 by a percentage basis. They are also up in raw sales numbers — in 2024, EV sales grew by a larger number than in 2023. And the same is true so far in 2025. Going back to 2023, 10.7 million EVs were sold globally in the first 10 months. Then in 2024, 13.3 million were sold, a difference of 2.6 million. And so far in 2025, 16.5 million EVs have sold, a difference of 3.2 million. Not only are the numbers getting bigger, but the growth in unit sales is getting bigger as well.

Even in America, the EV market "has increased so far this year, with 11.7% US EV sales growth YTD." In terms of US hybrid sales, much has been made of customers "shifting from EVs to hybrids," which is also not the case. Conventional gas-hybrid sales are indeed up and plug-in hybrids, which have grown more slowly than gas-hybrids/BEVs, have also shown some growth lately. But gas-hybrid sales have not come at the cost of EV sales, rather at the cost of gas-only car sales.

Because that's just the thing: the number of gas-only vehicles being sold worldwide is a number that actually is falling. That number continues to go down year over year. Sales of new gas-powered cars are down by about a quarter from their peak in 2017, and show no signs of recovering... And yet, somehow, virtually every headline you read is about the "EV sales slump," rather than the "gas-car sales slump." The one you keep hearing about isn't happening, but the one you rarely hear about is happening... No matter what region of the world you're in, EV sales were up in the first 10 months of this year.

Why Solarpunk Is Already Happening In Africa (substack.com) 130

Long-time Slashdot reader schwit1 shares a Substack post by economist/entrepreneur Skander Garroum: You know that feeling when you're waiting for the cable guy, and they said 'between 8am and 6pm, and you waste your entire day, and they never show up? Now imagine that, except the cable guy is 'electricity,' the day is '50 years,' and you're one of 600 million people. At some point, you stop waiting and figure it out yourself.

What's happening across Sub-Saharan Africa right now is the most ambitious infrastructure project in human history, except it's not being built by governments or utilities or World Bank consortiums. It's being built by startups selling solar panels to farmers on payment plans. And it's working. Over 30 million solar products sold in 2024. 400,000 new solar installations every month across Africa. 50% market share captured by companies that didn't exist 15 years ago. Carbon credits subsidizing the cost. IoT chips in every device. 90%+ repayment rates on loans to people earning $2/day.

And if you understand what's happening in Africa, you understand the template for how infrastructure will get built everywhere else for the next 50 years.

A 'Peak Oil' Prediction Surprise From the International Energy Agency (cnbc.com) 73

"The International Energy Agency's latest outlook signals that oil demand could keep growing through to the middle of the century," reports CNBC, "reflecting a sharp tonal shift from the world's energy watchdog and raising further questions about the future of fossil fuels." In its flagship World Energy Outlook, the Paris-based agency on Wednesday laid out a scenario in which demand for oil climbs to 113 million barrels per day by 2050, up 13% from 2024 levels. The IEA had previously estimated a peak in global fossil fuel demand before the end of this decade and said that, in order to reach net-zero emissions by 2050, there should be no new investments in coal, oil and gas projects... The IEA's end-of-decade peak oil forecast kick-started a long-running war of words with OPEC, an influential group of oil exporting countries, which accused the IEA of fearmongering and risking the destabilization of the global economy.

The IEA's latest forecast of increasing oil demand was outlined in its "Current Policies Scenario" — one of a number of scenarios outlined by the IEA. This one assumes no new policies or regulations beyond those already in place. The CPS was dropped five years ago amid energy market turmoil during the coronavirus pandemic, and its reintroduction follows pressure from the Trump administration... Gregory Brew, an analyst at Eurasia Group's Energy, Climate and Resources team, said the IEA's retreat on peak oil demand signified "a major shift" from the group's position over the last five years. "The justifications offered for the shift include policy changes in the U.S., where slow EV penetration indicates robust oil [consumption], but is also tied to expected increases in petrochemical and aviation fuel in East and Southeast Asia," Brew told CNBC by email. "It's unlikely the agency is adjusting based on political pressure — though there has been some of that, with the Trump administration criticizing the group's supposed bias in favor of renewable energy — and the shift reflects a broader skepticism that oil demand is set to peak any time soon," he added...

Alongside its CPS, the IEA also laid out projections under its so-called "Stated Policies Scenario" (STEPS), which reflects the prevailing direction of travel for the global energy system. In this assumption, the IEA said it expects oil demand to peak at 102 million barrels per day around 2030, before gradually declining. Global electric car sales are much stronger under this scenario compared to the CPS. The IEA said its multiple scenarios explore a range of consequences from various policy choices and should not be considered forecasts.

Jack Dorsey Funds diVine, a Vine Reboot That Includes Vine's Video Archive (techcrunch.com) 20

An anonymous reader quotes a report from TechCrunch: As generative AI content starts to fill our social apps, a project to bring back Vine's six-second looping videos is launching with Twitter co-founder Jack Dorsey's backing. On Thursday, a new app called diVine will give access to more than 100,000 archived Vine videos, restored from an older backup that was created before Vine's shutdown. The app won't just exist as a walk down memory lane; it will also allow users to create profiles and upload their own new Vine videos. However, unlike on traditional social media, where AI content is often haphazardly labeled, diVine will flag suspected generative AI content and prevent it from being posted. According to TechCrunch, a volunteer preservation group called the Archive Team saved Vine's content when it shut down in 2016. The only problem was that everything was stored in massive 40-50 GB binary blob files that were basically unusable for casual viewing.

Evan Henshaw-Plath (who goes by the name Rabble), an early Twitter employee and member of Jack Dorsey's nonprofit "and Other Stuff," dug into those backup files to try and salvage as much as he could. He spent months writing big-data extraction scripts, reverse-engineering how the archived binaries were structured, and reconstructing the original video files, old user info, view counts, and more. "I wasn't able to get all of them out, but I was able to get a lot out and basically reconstruct these Vines and these Vine users, and give each person a new user [profile] on this open network," he said.

Rabble estimates that through this process he was able to successfully recover 150,000-200,000 Vine videos from around 60,000 creators. diVine then rebuilt user profiles on top of the decentralized Nostr protocol so creators can reclaim their accounts, request takedowns, or upload missing videos.

You can check out the app for yourself at diVine.video. It's available in beta form on both iOS and Android.
