Longtime Slashdot reader Qbertino writes: Heise, a German IT news publisher, reports (English version via Google Translate) that the German state of Brandenburg is getting the world's tallest wind turbine, with an overall height of 300 meters (approximately 365 meters including rotor blades), designed to capture so-called third-level winds at higher altitudes. The article also includes a short 3D animation illustrating the construction and its size relative to standard modern wind turbines. The wind turbine uses a dual-framework base instead of a traditional closed tower to access stronger high-altitude winds, aiming to match offshore energy output while keeping onshore operating costs.

According to Heise, the prototype could lead to the installation of up to 1,000 units across Germany -- fitting seamlessly between existing wind farms without needing extra land.

Steam has begun banning games that violate the payment rules of banks and card networks, targeting adult content in particular -- especially titles with extreme or controversial themes. Engadget reports: The new clause states that "content that may violate the rules and standards set forth by Steam's payment processors and related card networks and banks, or internet network providers" is not allowed and could result in removal from the platform. In other words, if credit card companies get mad about something, they could actually have the power to ban a game. The clause goes on to say that this will affect "certain kinds of adult-only content."

This has likely already resulted in many games being pulled off the platform. SteamDB doesn't give a reason for these removals, but the timing does match up.

OpenAI has added Google Cloud as a provider for ChatGPT and its API, expanding beyond Microsoft to address growing demand for computing power. CNBC reports: OpenAI has added Google to a list of suppliers, specifying that ChatGPT and its application programming interface will use the Google Cloud Platform, as well as Microsoft, CoreWeave and Oracle. The announcement amounts to a win for Google, whose cloud unit is younger and smaller than Amazon's and Microsoft's. Google also has cloud business with Anthropic, which was established by former OpenAI executives. The Google infrastructure will run in the U.S., Japan, the Netherlands, Norway and the United Kingdom.

An anonymous reader quotes a report from Ars Technica: Chinese firms have begun rushing to order Nvidia's H20 AI chips as the company plans to resume sales to mainland China, Reuters reports. The chip giant expects to receive US government licenses soon so that it can restart shipments of the restricted processors just days after CEO Jensen Huang met with President Donald Trump, potentially generating $15 billion to $20 billion in additional revenue this year. Nvidia said in a statement that it is filing applications with the US government to resume H20 sales and that "the US government has assured Nvidia that licenses will be granted, and Nvidia hopes to start deliveries soon." [...]

The H20 chips represent Nvidia's most capable AI processors legally available in China, though they contain less computing power than versions sold elsewhere due to export restrictions imposed in 2022. Nvidia is currently banned from selling its most powerful GPUs in China. Despite these limitations, Chinese tech giants, including ByteDance and Tencent, are reportedly scrambling to place orders for the lesser chip through what sources describe as an approved list managed by Nvidia. "The Chinese market is massive, dynamic, and highly innovative, and it's also home to many AI researchers," Reuters reports Huang telling Chinese state broadcaster CCTV during his visit to Beijing, where he is scheduled to speak at a supply chain expo on Wednesday. "Therefore, it is indeed crucial for American companies to establish roots in the Chinese market."

The resumption of H20 sales marks a shift in US-China technology relations after the chips were effectively banned in April with an onerous export license requirement, forcing Nvidia to take a $4.5 billion write-off for excess inventory and purchase obligations. According to Reuters, Chinese sales generated $17 billion in revenue for Nvidia in the fiscal year ending January 26, representing 13 percent of total sales. Nvidia also announced it will introduce a new "RTX Pro" chip model specifically tailored to meet regulatory rules in the Chinese market, though the company provided no details about its specifications or capabilities.

An anonymous reader quotes a report from Bloomberg: CoreWeave is expanding a data center that is projected to double the electricity needs of a city near Dallas, another example of the strains that artificial intelligence workloads are placing on the US power supply. Local officials have grappled with how to handle the increased stress on the electricity grid from the project, according to a late 2024 presentation and emails seen by Bloomberg. The site is being developed by Core Scientific and will be used by OpenAI in Denton, Texas. Last week, CoreWeave announced it would acquire Core Scientific for about $9 billion, in part, to gain direct control of its data centers aimed at supplying AI work.

Denton, about 50 miles northwest of Dallas, has almost doubled its population in the last 25 years to about 166,000 residents. To meet the spike in AI-related power demand, the city is passing on any extra costs to the data center operator and constructing additional grid infrastructure, Antonio Puente, general manager of local utility Denton Municipal Electric, said in an interview. "To serve the entire load from Core Scientific, we do have some transmission challenges," Puente said. "We will have to make some additional transmission investments." [...] Like some other large AI data center projects, the site in Denton was focused on cryptocurrency mining before pivoting to AI workloads in December. This transition means unrelenting power consumption -- the site will no longer curtail operations when power prices are high -- which will increase grid strain. "Now you're talking about a facility that has to have energy 24 hours a day, 365 days a year," Puente said. That challenge will be mitigated by the addition of backup generators and batteries, he added.

Unlike many large projects, the Denton data center didn't receive local tax exemptions. Officials expect more than $600 million in property and sales tax from the data center expansion, more than double the costs it plans to incur, according to an analysis document seen by Bloomberg. It also anticipates that 135 new jobs will be created, according to the document. The Denton site, which is already being rented by CoreWeave, is Core Scientific's largest planned project at about 390 megawatts of power. It's "utilizing the majority of extra system capacity" in the city, wrote a utility executive in a January email seen by Bloomberg. Any additional large power users will exacerbate overloads on the grid, the executive added. "When fully built out, it will host one of the largest GPU clusters in North America," Core Scientific Chief Executive Officer Adam Sullivan said of the site during a May call. "Denton is a flagship facility."

The report notes that Texas could face electricity shortages as soon as 2026 due to surging power demand from data centers, oil and gas operations, and crypto mining.

An anonymous reader quotes a report from MIT Technology Review: California's statewide power grid operator is poised to become the first in North America to deploy artificial intelligence to manage outages, MIT Technology Review has learned. "We wanted to modernize our grid operations. This fits in perfectly with that," says Gopakumar Gopinathan, a senior advisor on power system technologies at the California Independent System Operator -- known as the CAISO and pronounced KAI-so. "AI is already transforming different industries. But we haven't seen many examples of it being used in our industry."

At the DTECH Midwest utility industry summit in Minneapolis on July 15, CAISO is set to announce a deal to run a pilot program using new AI software called Genie, from the energy-services giant OATI. The software uses generative AI to analyze and carry out real-time analyses for grid operators and comes with the potential to autonomously make decisions about key functions on the grid, a switch that might resemble going from uniformed traffic officers to sensor-equipped stoplights. But while CAISO may deliver electrons to cutting-edge Silicon Valley companies and laboratories, the actual task of managing the state's electrical system is surprisingly analog.

Today, CAISO engineers scan outage reports for keywords about maintenance that's planned or in the works, read through the notes, and then load each item into the grid software system to run calculations on how a downed line or transformer might affect power supply. "Even if it takes you less than a minute to scan one on average, when you amplify that over 200 or 300 outages, it adds up," says Abhimanyu Thakur, OATI's vice president of platforms, visualization, and analytics. "Then different departments are doing it for their own respective keywords. Now we consolidate all of that into a single dictionary of keywords and AI can do this scan and generate a report proactively." If CAISO finds that Genie produces reliable, more efficient data analyses for managing outages, Gopinathan says, the operator may consider automating more functions on the grid. "After a few rounds of testing, I think we'll have an idea about what is the right time to call it successful or not," he says.

Microsoft is testing a new adaptive energy saver mode in Windows 11 that automatically turns energy saver on or off based on system workload instead of battery percentage, aiming to extend laptop battery life without dimming screen brightness. The feature is currently available to Windows Insider testers and expected to roll out later this year. The Verge reports: The energy saver mode in Windows 11 typically dims a display brightness by 30 percent, disables transparency effects, and stop apps running in the background. Non-critical Windows update downloads are also paused, and certain apps like OneDrive, OneNote, and Phone Link may not sync fully while energy saver is enabled. This new adaptive energy saver mode, which will only be available on devices with a battery, will automatically enable or disable without affecting screen brightness. That will make it less noticeable on devices like laptops, tablets, and handhelds.

"Adaptive energy saver is an opt-in feature that automatically enables and disables energy saver, without changing screen brightness, based on the power state of the device and the current system load," explains Microsoft's Windows Insider team.

"In the battle for Ukraine, the front line is increasingly at a standstill" because of "rapid innovations in drone technology..." according to the Wall Street Journal. "Each side has hundreds of them constantly in the air across the 750-mile front line."

And drones "now bring everything from food and water to ammunition, power banks — and, in at least one case, a fire extinguisher — to the front, sparing soldiers trips through the most dangerous part of the battlefield where enemy drones might pick them off." Drones can lay mines, deliver everything from ammunition to medication and even evacuate wounded or dead soldiers. Crucially, drones spot any movement along the front line and are dispatched to strike enemy troops and vehicles. When Russia sent tank columns into Ukraine in February 2022, Ukraine needed to find out where they were headed — and fast. Enter the humble "wedding drone," available in stores for about $2,000 and repurposed to scan for enemy units rather than capture nuptial panoramas. Deployed by enthusiasts acting independently or attached to army units, the drones helped Ukrainian forces, which were vastly outnumbered and outgunned, to know exactly where to deploy to counter Russian arrowheads.

Surveillance drones quickly became a necessity rather than a luxury. Often provided by charity funds, they were used to scan enemy positions for equipment, stores and headquarters.... A cheap and simple tweak made the so-called wedding drones deadly. Tech buffs realized that a simple claw-like contraption, created using a 3-D printer, could be activated from the radio controller by turning on the drone's light, causing it to release a grenade. The explosion could wound or kill a soldier or even detonate an armored vehicle if dropped through its hatch. Over time, soldiers experimented with ways to add more explosives, for example by melting down explosives garnered from Soviet-era munitions and pouring them into new, lighter plastic casings.

No innovation has had a bigger impact on the war in Ukraine than first-person-view, or FPV, drones. With explosives strapped to them, FPVs fly directly into their targets, turning them into low-cost suicide bombers. Though FPVs don't deliver as much explosive punch as rockets, they are far more accurate — and the sheer volume that Ukraine has manufactured means they can be deployed to similar effect... Sitting in a bunker several miles behind the front, a drone pilot slips on FPV goggles to see the view from the drone's camera and fly it into an enemy position or asset. The Russians have since adopted FPVs en masse. Their abundance has played a central role in slowing down the movement of the front line. Anything within around 12 miles of the contact line can now become a target for FPVs. They are so cheap to make that both sides can expend them on any target — even a single infantryman.

Because they are so small and fast, FPVs are difficult to shoot down. The main defense against them has been electronic jamming systems, which disrupt the communication between the drone and the pilot. Though most drone innovations in the war have come from the Ukrainian side, the Russians pioneered the most important adaptation for FPV drones — the addition of a fiber-optic cable connecting the drone to the pilot that can overcome jamming.
Benjamin Franklin once predicted flying machines might "convince sovereigns of the folly of war... since it will be impracticable for the most potent of them to guard his dominions..."

HGP Storage is a (real) Texas company providing distributed battery-based, utility-scale energy storage systems. Founded in 2013, it has "successfully developed over 20+ sites and closed over 200 MW of distributed energy projects," according to its web site.

And they just teamed up with Enron, reports the Houston Chronicle: The company that took over the defunct Enron brand, led by a "Birds Aren't Real" cofounder [28-year-old Connor Gaydos], held a mostly satirical quarterly earnings call Thursday afternoon but gave updates to an application to become a legitimate Texas energy provider... DJ Withee, chief operating officer and legal counsel at HGP Storage, a company developing utility-scale battery storage farms, was introduced as Enron's vice president of energy service. Withee said he was brought on by Gaydos to set up the customer-facing energy services business.

Enron Energy Texas LLC, a subsidiary of Enron, filed to become a Texas retail electric provider in January. Gaining this designation would allow Enron to sell electricity plans to Texas consumers. "Our business model is actually going to be very simple," Withee said. "We buy wholesale electricity, just like everybody else, but because of our efficiency, because of our use of technology, we are going to have lower costs than our competitors. Lower costs means greater savings that we can pass back to our customers...." According to Withee, Enron's goal is to provide energy at a competitive lower cost that will not only make energy more accessible but also push other Texas retail companies to drop their own prices...

Enron's filing in January included sworn and notarized affidavits from a man named Gregory Forero, who was identified in the documents as vice president of Enron Texas Energy LLC. Forero is the founder and CEO of HGP Storage.
"Forero, who signed his name to three sworn affidavits attesting to the accuracy of the application, could risk perjury charges if the statements of intention to start a legitimate retail electric company are found to be false, according to the Texas Penal Code..."

But does this replace Enron's plan to sell egg-shaped home nuclear reactors?

An underwater turbine has been spinning for more than six years "to harness the power of ocean tides for electricity," reports the Associated Press. The long-running turbine (off the coast of Scotland) has now proven the commercial viability of the technology: Keeping a large, or grid-scale, turbine in place in the harsh sea environment that long is a record that helps pave the way for bigger tidal energy farms and makes it far more appealing to investors, according to the trade association Ocean Energy Europe. Tidal energy projects would be prohibitively expensive if the turbines had to be taken out of the water for maintenance every couple of years.

Tidal energy technologies are still in the early days of their commercial development, but their potential for generating clean energy is big. According to the National Renewable Energy Laboratory, marine energy, a term researchers use to refer to power generated from tides, currents, waves or temperature changes, is the world's largest untapped renewable energy resource.
This long-running tidal energy project off the coast of Scotland has four 1.5-megawatt turbines — enough to power 7,000 homes for a year, according to the article. But they plan to add 20 turbines in 2030 ("after needed upgrades to the electricity grid are finished"), and the site "could eventually hold as many as 130 turbines that are more powerful than those at the site today."

Electrek reports on the new Omo X, a scooter planned for release in 2026 that's "full of premium tech features that blur the lines between e-scooter and self-driving EV." At its recent launch in Jakarta, the Omo X didn't just sit pretty center stage, it actually drove itself onto the stage using its "Halo Pilot" system, which apparently comes complete with adaptive cruise control, remote summon, self-parking, and even automatic reversing and self-balancing at low speeds. This is legit autonomous behavior previously reserved for cars, now shrunk down and smoothed out for a two-wheeler. Under the hood — or rather, behind the sleek bodywork — Omoway's Halo architecture delivers collision warning, emergency-brake assist, blind spot monitoring, and V2V [vehicle-to-vehicle] communication.

The frame is modular, too. It can be reconfigured in step-through, straddle, or touring posture to suit casual riders, commuters, and motorcycle wannabes alike. That kind of flexibility isn't just a marketing gimmick, but rather it looks purpose-built to capture diverse motorcycle-heavy markets like Indonesia, which counts over 120 million two-wheelers and is quickly transitioning to electric models... It's tech-rich, head-turning, and seems built to evolve with software updates. The remote summon and AI-assisted features could genuinely simplify urban mobility, and tricks like automatically driving itself to a charging station sound legitimately useful...

[But] Omoway's vision here will have to carry extra sensors, actuators, and redundant systems to support those smart functions. With added costs and complexity, will riders in developing markets pay a premium, carry extra maintenance risk, or worry about obsolescence? Much hinges on Omoway's software support and local service networks.
The article reports a projected price around €3,500 (roughly $3,800). "And while Indonesia may have been the launchpad, global markets aren't off the table..."

"A Nintendo Switch 2 user reportedly got his brand-new console banned by Nintendo after buying used Switch 1 games and patching them on his console," reports Tom's Hardware: According to Reddit user dmanthey, they purchased four used titles off the Facebook marketplace, inserted them into the Switch 2, and had them all updated. When they turned on their handhelds the following day, they received a message saying that they were restricted from Nintendo's online services and that they couldn't even download the games they had already bought...

[T]hey were able to prove their innocence by pulling up the Facebook Marketplace listing for their games and sending the photos of their purchased cartridges. According to the Redditor, the process was painless and fast, and it was "so much easier than getting support from Microsoft or Sony...." Other users warned, though, that this isn't always a guaranteed resolution.

Nintendo is known for being protective of its intellectual property and delivers harsh penalties to anyone caught violating it. We've already had several reports of users getting banned for using Mig Flash, even on their own ROMs. And while it's not true that getting banned turns your Switch 2 into a brick, it will still prevent you from accessing the company's online services, which severely restricts its features and usability.
"Nintendo attaches unique codes to its Switch game cartridges to prevent piracy," notes Engadget. "However, bad actors can copy games onto a third-party device, like the MIG Flash, and then resell the physical game card. Once Nintendo detects two instances of its unique code being online at the same time, it will ban any accounts using it..." This anti-piracy policy isn't new — Nintendo has long had a reputation for fiercely combating any type of piracy — but it has become relevant again thanks to the recently released Switch 2, which offers backwards compatibility with original Switch titles. The company even recently amended its user agreement to allow itself the power to brick a Nintendo Switch that's caught running pirated games or mods.

Lucid Motors set a Guinness World Record for the longest journey by an electric car on a single charge, covering a distance of 749 miles (about 1,205 km), reports New Atlas. "In doing so, Lucid broke the 1,045-km (649-mile) record previously achieved by the Mercedes-Benz EQS450+ in June 2025 by the Japanese car website www.webcg.net/articles/-/52268webCG." The electric vehicle covered this journey between St. Moritz, Switzerland, and Munich, Germany, traveling through highways, secondary roads, and alpine roads — all without a single halt for charging. Given that the vehicle has a 960-km (596-mile) WLTP range, my guess is that the test team must have made good use of favorable road and weather conditions to make the feat possible. With a net elevation decrease of just over 1,310 m (about 4,300 ft) throughout the drive, the EV most certainly benefited from regenerative braking, a rather useful feature that turns downhill momentum back into battery power. Lucid has yet to release official data like average speed or total drive time, but what is apparent is that this was not a high-speed dash but rather a well-planned route to achieve one impressive result...

The Air Grand Touring has two all-wheel drive electric motors with a combined system output of 611 kW (819 horsepower) and 1,200 Nm (885 lb.ft) of torque. Power is provided by an NMC battery, which has a gross energy capacity of 117 kWh (112 kWh usable). Best of all, it can go from 0-60 mph in just three seconds flat... For reference, the almost half-priced BMW i4 and jazzy Porsche Taycan offer less than half the WLTP range of the Lucid Air GT. So, it's not like there's a head-to-head competition out there. Lucid is miles ahead in its class (pun intended!)

Starting at US$112,650, the Air Grand Touring is among the most luxurious sedans on the market right now. But as you can see, it comes at a price. Still, knowing that there is technology to conquer range anxiety is comforting. It might take a while, but there's no reason why we can't expect such range figures from reasonably priced EVs in the near future.

China "accounts for more than half of global coal use," reports Asia Times, "even as it builds the world's largest solar-panel and EV industries." Much of the world's solar gear is made on fossil power. The International Energy Agency finds that "coal generates over 60% of the electricity used for global solar PV manufacturing," far above coal's ~36% share of typical grids. That is because over 80% of PV factories sit in Chinese provinces like Xinjiang and Jiangsu, where coal dominates the grid.

China has poured over $50 billion into solar factories since 2011, roughly ten times Europe's investment, cutting panel costs by about 80% and fueling a worldwide solar boom. But those panels were produced on coal. In one analysis, they repay their manufacturing CO2 in only months, meaning the emissions were dumped up-front in China's coal plants. Any major disruption to China's coal power or factories (from grid shocks to trade barriers) could thus send ripples through the global PV market.

China's coal and heavy industries also feed its clean-tech supply chain. Coal-fired steel mills supply the aluminum and metal parts for EVs and panels, and coal chemicals provide battery precursors and silicon for solar... At the same time, Chinese oil and gas giants (CNPC, Sinopec) have set up solar, wind and battery divisions, redirecting fossil profits into green ventures.
Another interesting statistic from the article: "In Thailand, Asia's long-time auto hub, Chinese EV brands now command more than 70% of EV sales."

In June 2025, solar power became the leading source of electricity in the EU for the first time, surpassing nuclear and wind, while coal hit a record low. CBC reports: Solar generated 22.1 percent of the EU's electricity last month, up from 18.9 percent a year earlier, as record sunshine and continued solar installations pushed output to 45.4 terawatt hours. Nuclear followed closely at 21.8 percent and wind contributed 15.8 percent of the mix. At least 13 EU countries, including Germany, Spain and the Netherlands, recorded highest-ever monthly solar generation, [data from energy think tank Ember showed on Thursday.]

Coal's share of the EU electricity mix fell to a record low of 6.1 percent in June, compared to 8.8 percent last year, with 28 percent less electricity generated than a year earlier. Germany and Poland, which together generated nearly 80 percent of the 27-country bloc's coal-fired electricity in June, also saw record monthly lows. Coal accounted for 12.4 per cent of Germany's electricity mix and 42.9 percent of Poland's. Spain, nearing a full phase-out of coal, generated just 0.6 per cent of its electricity from coal in the same period.

Wind power also set new records in May and June, rebounding after poor wind conditions resulted in a weak start to the year. But despite record solar and wind output in June, fossil fuel usage in the first half of 2025 grew 13 percent from last year, driven by a 19 percent increase in gas generation to offset weak hydro and wind output earlier in the year. Electricity demand in the EU rose 2.2 percent in the first half of the year, with five of the first six months showing year-on-year increases. The next challenge for Europe's power system is to expand battery storage and grid flexibility to reduce its reliance on fossil fuels during non-solar hours, Ember said in the report.

An anonymous reader quotes a report from Ars Technica: For the second time in a year, Google has announced that it will render some of its past phones almost unusable with a software update, and users don't have any choice in the matter. After nerfing the Pixel 4a's battery capacity earlier this year, Google has now confirmed a similar update is rolling out to the Pixel 6a. The new July Android update adds "battery management features" that will make the phone unusable. Given the risks involved, Google had no choice but to act, but it could choose to take better care of its customers and use better components in the first place. Unfortunately, a lot more phones are about to end up in the trash. [...]

Pixel 4a units contained one of two different batteries, and only the one manufactured by a company called Lishen was downgraded. For the Pixel 6a, Google has decreed that the battery limits will be imposed when the cells hit 400 charge cycles. Beyond that, the risk of fire becomes too great -- there have been reports of Pixel 6a phones bursting into flames. Clearly, Google had to do something, but the remedies it settled on feel unnecessarily hostile to customers. It had a chance to do better the second time, but the solution for the Pixel 6a is more of the same. [...]

When Google killed the Pixel 4a's battery life, it offered a few options. You could have the battery replaced for free, get $50 cash, or accept a $100 credit in the Google Store. However, claiming the money or free battery was a frustrating experience that was rife with fees and caveats. The store credit is also only good on phones and can't be used with other promotions or discounts. And the battery swap? You'd better hope there's nothing else wrong with the device. If it has any damage, like cracked glass, it may not qualify for a free battery replacement.

Now we have the Pixel 6a Battery Performance Program with all the same problems. Pixel 6a owners can get $100 in cash or $150 in store credit. Alternatively, Google offers a free battery replacement with the same limits on phone condition. This is all particularly galling because the Pixel 6a is still an officially supported phone, with its final guaranteed update coming in 2027. Google also pulled previous software packages for this phone to prevent rollbacks. [...] If you have a Pixel 6a, the battery-killing update is rolling out now. You'll have no choice but to install it if you want to remain on the official software. Google has a support site where you can try to get a free battery swap or some cash.

Almost three-quarters of all solar and wind power projects being built globally are in China, says a new report that highlights the country's rapid expansion of renewable energy sources. From a report: China is building 510 gigawatts of utility-scale solar and wind projects, according to data from the Global Energy Monitor, a non-governmental organisation based in San Francisco. That compares with about 689GW under construction globally, GEM said.

A rough rule of thumb is that a gigawatt can potentially supply electricity for about 1mn homes. "China is [...] leading the world in global renewable energy build-out," the report said. "It continues to add solar and wind power at a record pace." China's expansion of clean energy sources is important for efforts to fight climate change, given the country's dominant role in global manufacturing.

An anonymous reader quotes a report from Reuters: America's largest power grid is under strain as data centers and AI chatbots consume power faster than new plants can be built. Electricity bills are projected to surge by more than 20% this summer in some parts of PJM Interconnection's territory, which covers 13 states -- from Illinois to Tennessee, Virginia to New Jersey -- serving 67 million customers in a region with the most data centers in the world. The governor of Pennsylvania is threatening to abandon the grid, the CEO has announced his departure and the chair of PJM's board of managers and another board member were voted out.

The upheaval at PJM started a year ago with a more than 800% jump in prices at its annual capacity auction. Rising prices out of the auction trickle down to everyday people's power bills. Now PJM is barreling towards its next capacity auction on Wednesday, when prices may rise even further. The auction aims to avoid blackouts by establishing a rate at which generators agree to pump out electricity during the most extreme periods of stress on the grid, usually the hottest and coldest days of the year. High prices out of the auction should spur new power plant construction, but that hasn't happened quickly enough in PJM's region as aging power plants continue to retire and data center demand explodes. PJM has made the situation worse by delaying auctions and pausing the application process for new plants, according to more than a dozen power developers, regulators, energy attorneys and other experts interviewed by Reuters.

PJM says the supply and demand crunch has been caused largely by factors outside of its control, including state energy policies that closed fossil-fuel fired power plants prematurely and data center growth in "Data Center Alley" in Northern Virginia and other burgeoning hubs in the Mid-Atlantic. "Prices will remain high as long as demand growth is outstripping supply -- this is a basic economic policy," said PJM spokesman Jeffrey Shields. "Right now, we need every megawatt we can get." New projects totaling about 46 gigawatts -- enough capacity to power 40 million homes -- have been cleared in recent years, "but are not getting built because of local opposition, supply chain backups or financing issues that have nothing to do with PJM," Shields said.

PJM has lost more than 5.6 net gigawatts in the last decade as power plants shut faster than new ones enter service, according to a PJM presentation filed with regulators this year. PJM added about 5 gigawatts of power-generating capacity in 2024, fewer than smaller grids in California and Texas. Meanwhile, data center demand is surging. By 2030, PJM expects 32 gigawatts of increased demand on its system, with all but two of those gigawatts coming from data centers.

Samsung on Wednesday unveiled three new foldable smartphones at a time when the company is facing increased competition from Chinese rivals such as Honor and Oppo, reports CNBC. The company's share of the global foldable phone market slipped to 45% in 2024, down from 54% a year earlier. Today's new devices include the ultra-thin Galaxy Z Fold 7, the clamshell-style Galaxy Z Flip 7, and the more affordable Flip 7 FE. Here's a breakdown of each: The Galaxy Z Fold 7 is super thin at a thickness of 8.9 millimeters (0.35 inches) closed and only 4.2 millimeters open. It's also much lighter than its predecessor, weighing 215 grams (7.62 ounces). These stats put the phone on par with both Honor's Magic V5 and the Oppo Find N5. The new Fold device has a 6.5-inch cover screen and an 8-inch main display when opened, making it bigger than its predecessor. It's also decked out with premium new cameras, featuring a 200-megapixel main lens, as well as a 10-megapixel telephoto sensor, 12-megapixel ultra-wide and two 10-megapixel front cameras on both the cover screen and on the main display.

Samsung's new Fold generation is, nevertheless, much more limited than other devices in the market when it comes to battery capacity. The Galaxy Z Fold 7 has a 4,400 milliampere-hour (mAh) battery -- far less than the 6,100 mAh power pack in Honor's Magic V5's or the Oppo Find N5's 5,600 mAh battery. Samsung says its device is capable of 24 hours of video playback.

Samsung's Galaxy Z Flip 7 is also thinner than its predecessor, coming in at 6.5 millimeters when opened flat. By contrast, the Galaxy Z Flip 6 has a depth of 6.9 millimeters when unfolded. The new phone has a 4.1-inch cover screen and a 6.9-inch main display. It comes with a 50-megapixel main camera and 12-megapixel ultra-wide sensor on the back and a 10-megapixel lens on the main display. It also has a bigger 4,300 mAh battery, which Samsung says supports 31 hours of video playtime on a single charge.

In addition to Flip 7, Samsung is also introducing a cheaper version of the phone, called the Galaxy Z Flip 7 FE, which is slightly smaller and thicker than its more premium counterpart. What about the AI features, you ask?
