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

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'

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 avril 2026 à 19:34
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 — 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 — 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.

Europe Has 'Maybe 6 Weeks of Jet Fuel Left'

The head of the International Energy Agency warned that Europe may have only "six weeks or so" of jet fuel left if oil supplies remain blocked by the Iran war and the Strait of Hormuz stays disrupted. The Associated Press reports: IEA Executive Director Fatih Birol painted a sobering picture of the global repercussions of what he called "the largest energy crisis we have ever faced," stemming from the pinch-off of oil, gas and other vital supplies through the Strait of Hormuz. "In the past there was a group called 'Dire Straits.' It's a dire strait now, and it is going to have major implications for the global economy. And the longer it goes, the worse it will be for the economic growth and inflation around the world," he told The Associated Press. The impact will be "higher petrol (gasoline) prices, higher gas prices, high electricity prices," said Birol, speaking in his Paris office looking out over the Eiffel Tower. Economic pain will be felt unevenly and "the countries who will suffer the most will not be those whose voice are heard a lot. It will be mainly the developing countries. Poorer countries in Asia, in Africa and in Latin America," said the Turkish economist and energy expert who has led the IEA since 2015. But without a settlement of the Iran war that permanently reopens the Strait of Hormuz, "Everybody is going to suffer," he added. "Some countries may be richer than the others. Some countries may have more energy than the others, but no country, no country is immune to this crisis," he said.

UK Households To Be Urged To Use More Power This Summer As Renewables Soar

Par : BeauHD
16 avril 2026 à 07:00
Longtime Slashdot reader AmiMoJo shares a report from the Guardian: Households will be called on to boost their consumption of Great Britain's record renewable energy this summer to help balance the power grid and lower energy bills. Under the new plans, people could be encouraged to run dishwashers and washing machines or charge up their electric vehicles when there is more wind and solar power than the electricity grid needs. The plan will be delivered with the help of energy suppliers, which may choose to offer heavily discounted or free electricity to their customers during specific periods when the energy system operator predicts there will be a surplus of electricity. Many suppliers already offer more than 2 million households the opportunity to pay lower rates for electricity used during off-peak hours but this will be the first time that the system operator will use this tool to help balance the grid. The National Energy System Operator (Neso) hopes that by issuing a market notice to call on energy users to increase their consumption it can avoid making hefty payments to turn wind and solar farms off when demand for electricity is low, which are ultimately paid for through energy bills.

Rivian's Illinois Factory Will Run On Recycled EV Batteries

An anonymous reader quotes a report from the Wall Street Journal: Rivian is joining with Redwood Materials to reuse EV batteries for energy storage -- the largest repurposed-battery energy storage system for an automotive manufacturer in the U.S., executives told The Wall Street Journal. Redwood Materials is a battery-recycling firm started by Tesla co-founder JB Straubel. Once completed later this year, Rivian's plant in Normal, Ill., will draw electricity from more than 100 Rivian EV batteries in an area the size of a small parking lot. It will reduce Rivian's dependence on the power grid during peak demand hours. "It saves Rivian money on what it takes to run the plant. It reduces the demand on the grid, which is great," Rivian Chief Executive Officer RJ Scaringe said in an interview. In the Rivian project, the batteries will come from either its test vehicles or from vehicles that have viable batteries but can no longer drive. Those batteries get sent off to Redwood, which integrates them into power storage units. Both companies declined to specify the cost of this project. The setup is expected to initially provide 10 megawatt-hours of energy, equivalent to about 1,000 home-energy battery storage units linked together, Redwood's Straubel said. "These batteries are already built," he said. "We need to integrate them and connect them together, but that can happen quite fast. They don't have to get imported from some other place." [...] Scaringe said that while branching into battery energy storage systems is "not a focus for us as a business right now," Rivian hopes to do more at its sites with Redwood. "There's hopefully a lot more, and there's going to be a lot of batteries we'll have access to," he said.
