    Why a Memphis Community Is Fighting Elon Musk’s Supercomputer

    by

    Residents say Mr. Musk’s data center for artificial intelligence is compounding their pollution burden and adding stress on the local electrical grid.Elon Musk, the world’s richest man, is building what he says will be the world’s largest supercomputer. Its electricity needs will rival those of 100,000 homes.The supercomputer’s neighbors in southwest Memphis have a problem with that.The project, part of Mr. Musk’s xAI artificial intelligence business, sits in an old manufacturing plant on more than 550 acres. Before beginning operations there in July, xAI rolled in flatbed trucks loaded with almost 20 mobile power plants, fueled by natural gas, to help meet its electricity demands.Residents of the heavily industrial community — already home to an oil refinery, a steel mill and chemical plants — see no upside. They contend that Mr. Musk’s project has made pollution worse in an area already enveloped in smog.“We’re getting more and more days a year where it is unhealthy for us to go outside,” said KeShaun Pearson, president of Memphis Community Against Pollution and a lifelong resident of the area near the xAI site.The xAI supercomputer center in Memphis is being built at the site of a former appliance factory.Whitten Sabbatini for The New York TimesThe center is to be used to train artificial intelligence models on thousands of powerful computer servers.Whitten Sabbatini for The New York TimesSo far, xAI is using the Memphis facility to develop its artificial intelligence models on a network of thousands of high-powered computer servers.

      As Texas Power Grid Faces New Strains, Renewables Help Meet Demand

      by

      Texas, the biggest oil-producing state, has turned to solar power and battery storage to see it through extreme weather. But with demand rising, much more power will be needed.During the scorching summer of 2023, the Texas energy grid wobbled as surging demand for electricity threatened to exceed supply. Several times, officials called on residents to conserve energy to avoid a grid failure.This year it turned out much better — thanks in large part to more renewable energy.The electrical grid in Texas has breezed through a summer in which, despite milder temperatures, the state again reached record levels of energy demand. It did so largely thanks to the substantial expansion of new solar farms.And the grid held strong even during the critical early evening hours — when the sun goes down and the nighttime winds have yet to pick up — with the help of an even newer source of energy in Texas and around the country: batteries.The federal government expects the amount of battery storage capacity across the country, almost nonexistent five years ago, to nearly double by the end of the year. Texas, which has already surpassed California in the amount of power coming from large-scale solar farms, was expected to gain on its West Coast rival in battery storage as well.The swift growth of battery storage as a source of power for the electric grid, along with the continued expansion of large-scale solar farms, could not have come at a better time. Texas, like many other states, is facing a surge in its power needs from data centers, new manufacturing plants, cryptocurrency mines, growing residential demand and increasingly intense summer heat. Officials estimate that Texas, already the nation’s largest electricity consumer, could roughly double its demand in just a few years.“Every state is going to go through this. Texas just happens to be the farthest along because we are growing our energy usage first,” said Michael Lee, the chief executive of Octopus Energy U.S., a subsidiary of the British electricity provider. “We’re seeing this in every other state, and all over the world.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Russia Maintains Punishing Pace of Deadly Strikes on Ukrainian Cities

      by

      A barrage on Vilniansk, a town in the south, killed seven, including three children, as attacks across Ukraine in the past few days have left dozens dead, according to local authorities.A Russian missile attack on a small town in southeastern Ukraine and the fiery inferno that followed killed at least seven civilians, including three children, the country’s authorities said as they surveyed on Sunday the deadly toll of two days of fierce Russian assaults.Yuriy Borzenko, chief doctor of Zaporizhzhia Regional Children’s Hospital, said in a phone interview that, aside from those killed, dozens of others, including a pregnant woman and five 14-year-old girls, were being treated for wounds after the attack on the southeastern town, Vilniansk, which took place on Saturday.The girls were out for a walk together in the afternoon sunshine, Dr. Borzenko said, when explosions from the projectiles tore through the center of the town, engulfing shops, cars and homes in flames. Shrapnel had embedded in the skull of one of the girls, who was left in a coma, he said, “still in between life and death.”“Her parents are in really bad shape, I just saw them,” he added.As the attacks have rained down, President Volodymyr Zelensky of Ukraine has reiterated his plea to loosen restrictions on the use of long-range American missiles known as ATACMS so that Ukraine can target warplanes at Russian air bases before they take to the sky on bombing runs.“Long-range strikes and modern air defense are the foundation for stopping the daily Russian terror,” he said on Sunday in a statement accompanying videos said to show the aftermath of a number of the week’s worst attacks.The strike in Vilniansk was one of a series of attacks across Ukraine, which have killed at least 24 civilians since Friday evening, according to local officials and emergency workers, who said that scores more had been wounded.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      How Electric Car Batteries Might Aid the Grid (and Win Over Drivers)

      by

      Automakers are exploring energy storage as a way to help utilities and save customers money, turning an expensive component into an industry asset.Electric cars are more expensive than gasoline models largely because batteries cost so much. But new technology could turn those pricey devices into an asset, giving owners benefits like reduced utility bills, lower lease payments or free parking.Ford Motor, General Motors, BMW and other automakers are exploring how electric-car batteries could be used to store excess renewable energy to help utilities deal with fluctuations in supply and demand for power. Automakers would make money by serving as intermediaries between car owners and power suppliers.Millions of cars could be thought of as a huge energy system that, for the first time, will be connected to another enormous energy system, the electrical grid, said Matthias Preindl, an associate professor of power electronic systems at Columbia University.“We’re just at the starting point,” Dr. Preindl said. “They will interact more in the future, and they can potentially support one another — or stress one another.”A large flat screen on the wall of the Munich offices of the Mobility House, a firm whose investors include Mercedes-Benz and Renault, illustrates one way that carmakers could profit while helping to stabilize the grid.The graphs and numbers on the screen provide a real-time picture of a European energy market where investors and utilities buy and sell electricity. The price changes from minute to minute as supply and demand surge or ebb.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Electricity From Coal Is Pricey. Should Consumers Have to Pay?

      by

      Environmental groups are making a new economic argument against coal, the heaviest polluting fossil fuel. Some regulators are listening.For decades, environmentalists fought power plants that burn coal, the dirtiest fossil fuel, by highlighting their pollution: soot, mercury and the carbon dioxide that is dangerously heating the planet.But increasingly, opponents have been making an economic argument, telling regulators that electricity produced by coal is more expensive for consumers than power generated by solar, wind and other renewable sources.And that’s been a winning strategy recently in two states where regulators forbade utilities from recouping their losses from coal-fired plants by passing those costs to ratepayers. The Sierra Club and the Natural Resources Defense Council, two leading environmental groups, are hoping that if utilities are forced to absorb all the costs of burning coal, it could speed the closures of uneconomical plants.The groups are focused on utilities that generate electricity from coal and also distribute it. Those utilities have historically been allowed to pass their operating losses to customers, leaving them with costly electric bills while the plants emitted carbon dioxide that could have been avoided with a different fuel source, according to the environmental groups.About 75 percent of the nation’s roughly 200 coal-fired power plants are owned by utilities that control both generation and distribution.In 2023, utilities across the United States incurred about $3 billion in losses by running coal-fired power plants when it was cheaper to buy power from lower-cost, less polluting sources, according to RMI, a nonprofit research organization focused on clean energy. About 96 percent of those losses were incurred by plants that controlled both power generation and distribution, the organization said.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Northern Lights Set to Return Tonight as Extreme Solar Storm Continues

      by

      Electrical utilities said they weathered earlier conditions as persistent geomagnetic storms were expected to cause another light show in evening skies.Night skies in many parts of the Northern Hemisphere are expected to bloom again on Saturday night with the vivid colors of the northern lights, or aurora borealis, as a powerful geomagnetic storm caused by a hyperactive sun persists through the weekend.The National Oceanic and Atmospheric Administration, which monitors space weather, said in an update on Saturday that it continued to observe solar activity that could lead to periods of “severe-extreme” geomagnetic storms. The federal agency first issued a warning on Friday as bursts of material from the sun’s surface traveled into Earth’s atmosphere, causing irregularities in power, navigation and communication systems.Major power utilities had largely prepared their electrical grids for the solar storm, and their customers were unaffected.For most people, the solar storm was a gift: It caused ribbons of pink, purple and green light across night skies of much of the United States, Canada and Europe. Where evening skies are clear on Saturday, the lights can be expected again.Known as aurora, the light is caused by particles from the sun interacting with gases in Earth’s atmosphere, and is usually only observed at latitudes closer to the North or South Pole. But on Friday night, residents of lower latitudes, including those in North Carolina and Arizona, saw the dancing lights.Jane Wong, 30, of San Francisco, drove to the Presidio overlooking the Golden Gate Bridge where conditions started out foggy. But at midnight, her wait paid off as the sky started to clear.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      California Will Add a Fixed Charge to Electric Bills and Reduce Rates

      by

      Officials said the decision would lower bills and encourage people to use cars and appliances that did not use fossil fuels, but some experts said it would discourage energy efficiency.Utility regulators in California on Thursday changed how most residents will pay for energy by adding a new fixed monthly charge and lowering the rates that apply to energy use. Officials said the shift would reduce monthly bills for millions of residents and support the use of electric vehicles and appliances that run on electricity, rather than fossil fuels.The decision by the California Public Utilities Commission will apply to the rates charged by investor-owned utilities, which provide power to about 70 percent of the state. Starting next year, most customers of those companies will be required to pay a $24.15 monthly charge. Low-income customers will pay $6 to $12 a month.Regulators said the revenue from the fixed charge would be paired with a roughly 20 percent reduction in rates assessed by how many kilowatts of energy were used per hour by a home or business. (The average American home uses around 1,000 kilowatt-hours in a month.) California’s residential electric rates, which averaged 31.2 cents per kilowatt-hour in February, are the highest in the country after Hawaii, where rates were about 44 cents, according to the federal Energy Information Administration. The national average in February was 16.1 cents.Some energy experts have argued that California’s high rates for energy use are very likely discouraging some people from buying electric vehicles, heat pumps and induction stoves to replace cars and appliances that run on gasoline and natural gas.“This new billing structure puts us further on the path toward a decarbonized future, while enhancing affordability for low-income customers and those most impacted from climate change-driven heat events,” said Alice Reynolds, president of the utilities commission.We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.

      Baltimore Investigation Turns to Ship’s Deadly Mechanical Failure

      by

      The Dali reported a power blackout and steering problems before hitting the Francis Scott Key Bridge in Baltimore. The disastrous mechanical failure so far has not been explained.Just minutes before the cargo ship Dali was set to glide under Baltimore’s Francis Scott Key Bridge, the ship’s alarms began to blare. The lights went out. The engine halted. Even the rudder, which the crew uses to maneuver the vessel, was frozen.As a frantic effort to restore the ship was underway, the pilot soon recognized that the aimless vessel was drifting toward disaster, and called for help.The cascading collapse of the vessel’s most crucial operating systems left the Dali adrift until it ultimately collided with the Key bridge, knocking the span into the river and killing six people. But as crews this week were still sorting out how to disentangle the ship and recover the bodies of those who died, investigators were also turning to the most central question: What could have caused such a catastrophic failure at the worst possible moment?Engineers, captains and shipping officials around the world are waiting for that answer in an era when the industry’s largest ships can carry four times as much cargo as those just a few decades ago, navigating through congested urban ports under bridges that may carry tens of thousands of people a day,Already, a few key questions are emerging, according to engineers and shipping experts monitoring the investigation, and most of them point to the electrical generators that power nearly every system on the 984-foot vessel, not only the lights, navigation and steering, but the pumps that provide fuel, oil and water to the massive diesel engine.The “complete blackout” reported by the pilot is hard to explain in today’s shipping world, in which large commercial vessels now operate with a range of automation, computerized monitoring, and built-in redundancies and backup systems designed to avert just such a calamity.

      The Last Coal-Fired Power Plants in New England Are to Close

      by

      The company that owns the Merrimack and Schiller stations in New Hampshire plans to turn them into solar farms and battery storage for offshore wind.The last two coal-fired power plants in New England are set to close by 2025 and 2028, ending the use of a fossil fuel that supplied electricity to the region for more than 50 years.The decision to close the Merrimack and Schiller stations, both in New Hampshire, makes New England the second region in the country, after the Pacific Northwest, to stop burning coal.Environmentalists waged a five-year legal battle against the New Hampshire plants, saying that the owner had discharged warm water from steam turbines into a nearby river without cooling it first to match the natural temperature.In a settlement reached on Wednesday with the Sierra Club and the Conservative Law Foundation, Granite Shore Power, the owner of the plants, agreed that Schiller would not run after Dec. 31, 2025 and that Merrimack would cease operations no later than June 2028.“This announcement is the culmination of years of persistence and dedication from so many people across New England,” said Gina McCarthy, a former national climate adviser to President Biden and former administrator of the Environmental Protection Agency during the Obama administration who is now a senior adviser at Bloomberg Philanthropies, which supports efforts to phase out coal.“I’m wicked proud to live in New England today and be here,” Ms. McCarthy said. “Every day, we’re showing the rest of the country that we will secure our clean energy future without compromising.”We are having trouble retrieving the article content.Please enable JavaScript in your browser settings.Thank you for your patience while we verify access.
