69 million people people live in the United Kingdom. And now >Electrek reports: Battery-electric cars took 32% of the UK's new car market in October, while petrol cars fell to just 37.2%, according to new data from the SMMT. That's the closest the two have been. At the current pace, electric cars will outsell petrol in the UK within a year. And it could happen as soon as this December. The UK registered 152,730 new cars in October, up 5.4% year-over-year and the 11th straight month of growth for the overall market. All of that growth came from plug-ins. Battery-electric vehicle registrations jumped 32.7% to 48,858 units, and plug-in hybrids rose 30.1% to 22,898. Meanwhile, petrol fell 11.6% to 56,876 units, diesel dropped 15.9%, and even conventional hybrids were down 5%... The brands growing fastest in the UK are mostly Chinese. BYD registered 6,065 cars in October, up 73%. Jaecoo more than doubled to 6,089 units, Chery nearly tripled to 3,707, and Leapmotor doubled to 1,773. MG was up 85%. Looking at trend lines, EV car sales surpass petrol sales "around August 2027 at roughly 33% each," the article points out. "But that's the slow scenario, because it ignores December." UK battery-electric vehicle share spikes every December as automakers push volume to get closer to their zero-emission vehicle mandate targets... Petrol's days as the UK's default car are numbered. The only question is whether the milestone comes in December or sometime in 2027.

"According to a new study by researchers at Harvard University and the University of Pennsylvania, data centers are probably having only a small effect on residential electricity prices," reports the Washington Post. "The researchers calculated that these operations were responsible for just 4% of the utility rate increases over the last five years..." There are certainly some areas — like in Pennsylvania, Virginia, Ohio and other states covered by grid operator PJM — where data centers have skyrocketed demand, pushing some costs onto residential customers. But multiple studies by different researchers and organizations have failed to find a strong connection between data centers and the overall trajectory of U.S. electricity prices in recent years. Another analysis earlier this year by researchers at the Massachusetts Institute of Technology found that, between 2010 and 2024, data centers increased average electricity prices for residential customers by just 2.1%. Last year, research from the Brattle Group and Lawrence Berkeley National Laboratory found that data centers were actually decreasing costs in certain regions. And another study by the Electric Power Research Institute found that a doubling of data center capacity between 2019 and 2024 resulted in a 4 percent drop in home electricity prices... The new Harvard and Penn study found a slightly higher impact on industrial electricity prices — the price paid by manufacturers and large facilities. For those customers, data centers were responsible for 15% of the price increase between 2020 and 2025. But for ordinary Americans... the changes simply were not substantial [according to Wharton School professor Serguei Netessine, one of the study's authors]. "So far we have no evidence that data centers increase prices all that much," Netessine said. Instead, he said, prices are rising due to more quotidian factors: rising gas prices, an aging electricity grid, and wildfires and hurricanes requiring improvements to the grid and recovery after disaster... If the number of data centers continue to boom, experts say, residential prices could be affected more down the line. Data center electricity demand is expected to increase steeply over the next few years, requiring new power generation — wind, solar or natural gas — to be put onto the grid. And residents have issues with data centers that go beyond the price of electricity. The new developments have been singled out for loud noise, polluting power generation, and for disturbing residential neighborhoods and natural landscapes. According to the Pew Research Center, more than half of Americans say that data centers are mostly bad for the environment. Others feel that the AI race — which could ultimately leave many Americans out of work — is being forced upon them. "I think generally what we're seeing is a broader range of reasons the public has opposed data centers," [said Ryan Hledik, principal at the Brattle Group]. "Concern about AI leading to loss of jobs — all of that is getting packaged together."

Rather than racing toward their net-zero targets, Amazon and other AI/cloud computing companies "are driving emissions sharply higher," reports the Washington Post: To support their data centers, tech firms are driving construction of a new generation of supersized, gas-fired power plants that could lock in hundreds of millions of tons of climate pollution for decades to come, according to corporate disclosures and an analysis conducted for The Post by a researcher at the Harvard T.H. Chan School of Public Health. Industry estimates show these projects have put the tech sector on course to grow from a modest driver of industrial carbon pollution into one of the world's biggest emitters of greenhouse gases. Some anticipate that its share of global carbon emissions will increase as much as fivefold from 2020 to 2030. That would leave the tech industry churning out more than half the climate pollution created by global aviation or shipping — sectors long associated with driving warming... Already, Amazon's carbon footprint reached 80.85 million metric tons last year — 58% larger than when [Amazon CEO Jeff] Bezos pledged to shrink it. The company has veered far from the path laid out in the Paris agreement, which would have emissions falling steeply by now and dropping to 43% below 2019 levels by 2030. The tech companies say in corporate disclosures and public statements that they remain committed to their net zero targets, and they suggest the emissions surge is temporary — to be mitigated down the road, when new energy technologies enable the data centers to run cleaner and more efficiently. They also stress that they continue to invest in clean energy and rank as some of the world's biggest consumers of it. With some complicated accounting maneuvers and carbon credit purchases, their solar, wind and geothermal installations partly cancel out their gas emissions, according to corporate disclosures. A June report from international insurance/asset management Allianz found the world's data center emissions are on track to double to 643 million tons of CO2 annually between 2020 and 2030, the article points out. And they cite American data centers contributing to the problem: Just two gas projects Amazon signed on to for data centers planned in Texas and Pennsylvania "would produce more carbon pollution than the dirtiest facility in the country," an Alabama coal plant powering 1 million homes. Meta is building a nearly six-square-mile campus in Louisiana "that will consume as much electricity as three cities the size of New Orleans." "A sprawling Microsoft project in West Texas involving a giant gas plant built by Chevron and a Google project in Wyoming that would consume five times as much electricity as every household in that state would vastly expand the emissions associated with those companies." "A data center campus in Pike County, Ohio, that will support OpenAI's artificial intelligence operations will consume significantly more gas power, and, therefore, emit more carbon pollution, than the Microsoft and Google projects combined."

Ford's upcoming $28,350 Fathom electric truck will include a built-in inverter capable of supplying up to 10 kW of AC power to a home, bringing bidirectional charging to a significantly cheaper EV. Owners will still need additional Ford home hardware for features like outage backup and peak-rate energy management, but the company expects the necessary equipment to cost substantially less than its previous-generation system. CNET reports: The upcoming Fathom will be based on what Ford calls its Universal EV Platform, designed with the aid of its 2023 acquisition, startup Auto Motive Power, with bidirectional power on the plate from the start. The hardware required to invert the battery's DC energy to an estimated 10 kW of AC home power will be built into the truck, so it won't require a separate wall-mounted inverter box. Ford says the Fathom's system will meet all applicable UL 1741 requirements and IEEE 1547 standards to ensure the vehicle is safely connected to the grid. As for the actual hardware you plug into your car, all signs point to the Fathom using the NACS plug type pioneered by Tesla and now widely adopted by new EVs in North America. In terms of the communication standard -- the one that governs how AC power is routed from the slim wall box to the car's onboard charger -- that'll be via SAE J3068, a software protocol developed for high-power, heavy-duty AC charging. [...] However, while Fathom's Universal EV Platform eliminates the need for a wall inverter box, it doesn't completely bypass the need for additional hardware to make your home ready to accept bidirectional power. Say you wanted to take advantage of the Home Power Management feature to draw energy into the Fathom's battery when power is cheapest, and then use that energy to offset peak-hour usage when power is most expensive. You'll have to install at least the Ford Home Power Station in your home, at an additional cost. The automaker hasn't specified pricing, but says that it's working to reduce costs and expects this component alone to cost half as much as the first-generation Ford Home Energy system, which debuted at around $1,300. That could put the new system at roughly $650.

Google is funding one of the nation's largest "virtual power plants," paying homes and businesses indirectly to reduce electricity consumption during periods of peak demand so more grid capacity can be available for data centers. Under its expanded deal with Voltus, the program could provide up to 1,070 megawatts in the Mid-Atlantic PJM grid -- roughly the output of a large nuclear reactor. The New York Times reports: That electricity won't come from new power plants. Instead, Voltus will sign up homes and businesses and give them financial incentives to curb their usage when local power demand is high or the grid is strained. Many of these reductions could occur automatically, such as through smart thermostats that dial back air-conditioning during peak summer hours or batteries that can provide temporary on-site power. Each of these tweaks frees up only a small amount of power on its own. But by aggregating them across thousands of businesses and homes, Voltus says it can reliably provide lots of extra capacity when it's most needed, and do so within a few years. While tech companies will likely ultimately need to build traditional power plants if they want to keep building large data centers, this approach could be a faster, cheaper and less-polluting option in the interim. "We really see virtual power plants as a critical short-term solution," said Ellen Zuckerman, head of energy market development for North and South America at Google. "It's a way to invest in our communities, really double down on our clean energy ambition, but also meet capacity at speed and scale."

An anonymous reader quotes a report from TechCrunch: Amazon is funding development of a proposed 960-megawatt nuclear plant in Indiana and would be the first customer to buy its power, the companies announced Monday. Utility company American Electric Power (AEP) would operate the plant. X-energy, which designs small modular nuclear reactors and went public in April, would supply the reactors. The new power plant would consist of 12 Xe-100 small modular reactors and be located on the site of a demolished coal power plant just south of Terre Haute. The deal is the second commercial agreement between Amazon and X-energy, and it's three times larger than the first, which was announced two years ago. Amazon has invested heavily in X-energy, leading a $700 million Series C-1 round in October 2024. The two companies have said they ultimately plan to build 5 gigawatts of new nuclear generating capacity in the U.S. by 2039. Unlike many newly announced power plants, these reactors would be connected to the public electric grid, though Amazon says the power would also serve its data centers. The companies' aggressive timeline still depends on X-energy successfully delivering its first power plant at a Dow Chemical plant southeast of Houston, Texas. The site, called Seadrift, has recently been at the center of a lawsuit filed by the state of Texas, which accuses the plant of "habitual non-compliance" with water and solid-waste regulations and permits. X-energy has yet to break ground at Seadrift, which will host four Xe-100 reactors to provide the chemical plant with heat and electricity. The company said its construction permit is in the final phases of the U.S. Nuclear Regulatory Commission's review process.

America is "making an unprecedented attempt to revive three shuttered nuclear plants to meet rising energy demand," reports the Los Angeles Times, "Two of the plants have contracts with Big Tech companies that will pay a premium to get large amounts of carbon-free energy for data centers..." No commercial nuclear reactor is known to have resumed generating electricity after beginning the decommissioning process that takes one out of service, though some reactors have restarted after long outages. The Department of Energy is lending as much as $4.4 billion to restart the Palisades Power Plant in Michigan, the Crane Clean Energy Center on Pennsylvania's Three Mile Island and the Duane Arnold Energy Center in Iowa to restore a combined 2.25 gigawatts of electricity, which can power roughly 2 million homes and businesses. All three of the plants closed before their licenses expired, largely because the electricity they produced was considered too expensive... Restarting a reactor is a fairly quick way to get a lot of electricity, and it's cheaper than building a new, large reactor, said nuclear engineering expert Todd Allen... Edwin Lyman, at the Union of Concerned Scientists, said the taxpayer money being used should go toward addressing safety risks. For example, most U.S. plants were built between 1970 and 1990 and were designed to withstand natural disasters of that era, said Lyman, director of nuclear power safety at UCS. But climate change is making extreme weather events more frequent and severe. "It's possible, if they set the right level of safety and spend the necessary funds to meet that, they could restore these plants to operable condition," he said. "That's not happening at this point...." NextEra Energy and Google are collaborating to restart Duane Arnold by early 2029... Microsoft has a contract with the Crane Clean Energy Center on Three Mile Island just outside Harrisburg. The plant was the site of the nation's worst commercial nuclear power accident in 1979. The accident destroyed one reactor, leaving the plant with one functioning. In 2019, Constellation Energy's then-parent company Exelon shut down the functioning reactor, saying it was losing money and that Pennsylvania lawmakers had refused to subsidize it. Constellation Energy announced in 2024 that it would spend $1.6 billion to restart the reactor under a 20-year agreement with Microsoft. It hopes to bring the plant back online in 2027... Palisades is expected to be the first nuclear plant in the world to resume generating power after beginning the decommissioning process.

"This year, nearly the entire fleet of 94 U.S. nuclear reactors has been offered the chance to integrate AI into its operations, and most have taken it," reports IEEE Spectrum: In August, California-based Atomic Canyon launched NIVA, the Nuclear Industry Virtual Assistant, which was developed in cooperation with nuclear-industry groups. The assistant was pilot-tested in nuclear plants run by Constellation Energy and is now available to the United States' entire fleet of reactors.... Meanwhile, the AI-for-nuclear startup Nuclearn says its products have gone to work with more than 65 U.S. partners, a total that includes many traditional plants but also an integration with NuScale Power Corp. that is working toward advanced small nuclear reactors. Microsoft and Nvidia have collaborated on a project to apply AI toward optimizing "the entire life cycle of a nuclear plant, spanning site permitting, design, construction, and continuous operations." The reason for the rapid adoption, according to Nuclearn CFO and cofounder Jerrold Vincent, is twofold. First, the technology companies banking their futures on AI are also keen on a revival of nuclear power to provide the electricity for all those data centers. Vincent says AI is also ideal for addressing some of the nuclear industry's most pressing problems. Many of the things that make reactors so difficult to operate — intricate regulations, along with complex systems for management and maintenance — are exactly the kinds of tasks that AI is good at. The industry is staggering to deal with aging hardware and an aging workforce. If it is going to survive, and have a real shot at a nuclear revival, it will need help from machine intelligence, Vincent says... Right now, the principal output of a nuclear reactor (aside from electricity) is paperwork. Nuclear plants produce piles of documentation to demonstrate regulatory compliance and to record how they respond to any potential problem, from a crack in the sidewalk to a fault in the reactor... Nuclearn's AI products help plants search through large repositories of data more efficiently to more quickly file paperwork with the federal government or figure out how a particular problem was solved in the past. "If you think of it as ChatGPT for nuclear," he says, "it's actually not a bad place to start." It's especially important because the nuclear power industry "has a remarkably skilled but quickly shrinking workforce tasked with keeping old reactors online and possibly starting up new ones to meet surging demand for electricity," the article points out. It also stresses that "So far, both the Nuclearn and NIVA large language models used in the nuclear world report to humans and don't go anywhere near power plant operations."

Could this push solar cell efficiency beyond the theoretical 33% limit? Interesting Engineering reports: Researchers at the University of Groningen in the Netherlands found that tin-based perovskite solar cells can slow heat loss from high-energy "hot electrons..." When sunlight strikes a panel, photons jump-start electrons into action. The most energetic photons create super-charged hot electrons... [but] in fractions of a trillionth of a second, these high-energy particles rapidly cool, dumping their bonus energy as waste heat before ever leaving the solar cell... In collaboration with Maria Antonietta Loi, professor of Photophysics and Optoelectronics, the team created an experimental setup. Using a specialized solar cell material called tin-based perovskite, Loi's lab performed a feat many thought impossible: she slowed the heat loss down by a factor of 1,000. Suddenly, the extra energy lingered for nanoseconds instead of vanishing in picoseconds... To solve the puzzle, Koster and PhD student Tim Faber built digital simulations to peel back the quantum layers. And discovered a surprising double-action mechanism at work... The simulations matched the exact nanosecond delay observed in the lab... These specialized materials could be used to build a new generation of super-efficient solar cells. Tin-based metal halide perovskites are non-toxic, eco-friendly crystalline materials for high-performance solar energy conversion... The material possesses an unusually low electron mass. As a result, electric charges move quickly and retain extra thermal energy for extended periods. This combination of broad light absorption, efficient charge movement, and prolonged energy retention makes these materials prime candidates for next-generation solar panels. "There are many other questions that still need answers," the team said in their announcement, "but in theory, this discovery could allow the creation of more efficient solar cells, beyond the theoretical limit of 33 percent."

More than 200,000 barrels of low-level radioactive waste were stored on the floor of the Atlantic Ocean between 1949 and 1982, reports ScienceAlert. Whatever happened to those barrels? Scientists have descended to the wreckage in a crewed submersible to investigate — and found many of the barrels corroded and degraded, their contents spilling across the seafloor. Surprisingly, this isn't necessarily a subversion of the original plan... The International Atomic Energy Agency recommends that low-level waste be disposed of in robust containment in isolation for at least a few hundred years — but back in the mid-20th century, the recommendations were a little different. The contemporaneous guidelines recommended that containers needed to reach the seafloor intact and remain sealed only long enough for the short-lived radionuclides to decay. After that, the remaining waste was expected to slowly escape and disperse through the surrounding ocean. Not everything in the barrels would conveniently decay away, however. They contained a radioactive hodgepodge, including cesium-137, plutonium isotopes, and tritium, some of which can persist for thousands of years... [A] few years ago, nuclear engineer Patrick Chardon and marine geologist Javier Escartín of the French National Center for Scientific Research started to wonder what had become of the dumped waste. That question eventually became NODSSUM — Nuclear Ocean Dump Site Survey Monitoring — an interdisciplinary project bringing together nuclear physics, geology, oceanography, biology, and marine chemistry to find the barrels and investigate what, if anything, they were doing to the surrounding environment.... [T]he barrels also appeared to function as tiny oases on the otherwise sparsely populated sandy seafloor. Anemones had attached themselves to the barrels. Sponges, sea cucumbers, fish, and crustaceans lived around them, with crabs apparently particularly fond of the artificial shelters... Instruments aboard the ship detected significant signals of cobalt-60 and niobium-94, which the researchers could specifically link to the dumped waste... [Samples are now being analyzed] There is precedent, however, to suggest that even striking levels of radioactivity around a source don't necessarily spread very far. A recent study of the sunken Soviet submarine Komsomolets found radionuclide levels hundreds of thousands of times above background immediately around the leaking reactor — but those levels dropped sharply within just a few meters as the material dispersed through the seawater. The NODSSUM team similarly found that, despite the significant radioactive signals around the barrels, activity levels weren't high enough to pose major radiation-protection problems for the scientists handling the samples. [Their three-person submersible] Nautile and the instruments it carried showed no signs of contamination. The real achievement was mapping the exact location of the barrels. "None of this means the waste is harmless," the article concludes — but it also doesn't mean we're about to be overrun by radioactive crabs."

"As parts of the Southern California coastline crumbled into the sea, slammed by intense waves and flooding in recent days, oceanographer Kim McCoy had one thing on his mind," reports the Los Angeles Times. He was thinking about "the nuclear waste set in concrete on the beach near San Clemente at the shuttered San Onofre nuclear power plant." "Rising sea levels, storm waves, El Niño which increases wave height ... these could wash away a section of the walkway that protects the San Onofre seawall, and the waste canisters are just 100 feet away from that," the former wave dynamics researcher and longtime advocate against beach storage of nuclear waste said. Most experts agree the risk of erosion damaging the nuclear waste storage system is extremely low in the near term. The plant's owner, Southern California Edison, has promised the California Coastal Commission to move the waste to higher elevation on-site if modeling shows sea level rise and erosion will start to pose a challenge. But the recent waves, fueled by Hurricane Marie far away in the Pacific, resurfaced the issue of the ultimate fate of the highly radioactive spent fuel that used to power the reactors. "At the moment, it is under control, I think it's essential to say that," said James Day, a geology professor at UC San Diego. "But geologically we must be thinking long term. The waste lasts for hundreds, if not thousands of generations...." [In 2103 some of the site's canisters' approach their intended 100-year lifespans, and the utility may have to start the transfer into new cansiters.] The distinctive twin domes that once housed the reactor cores will start coming down early next year. But the 3.6 million pounds of high-level waste will stay in the coastal community indefinitely. How much of a safety hazard that is depends on whom you ask. "San Onofre is sitting on some fairly young rocks in a seismically active region," Day said at a recent symposium at the Scripps Seaside Forum in La Jolla, hosted by the Samuel Lawrence Foundation. "This is not the sort of place you would leave nuclear waste." Others noted that collapse of beach slopes could make the site more vulnerable to tsunamis. They spoke of the corrosive effects of the ocean air on the steel canisters that hold the waste... Edison says its system will be safe for decades to come. "The maximum credible tsunami here would not even overtake the seawall," said Manuel Camargo, principal manager of decommissioning for Edison, standing on the concrete pad that holds the steel waste storage canisters. "The maximum credible earthquake, somewhere around a 7.0 magnitude, would produce something about half of what this system is designed to withstand...." Edison is bolstering a path below the seawall. Based on state data from the California Ocean Protection Council, the seawall would not be inundated before 2050, Camargo said... Plans for a deep geological repository beneath Yucca Mountain in Nevada crumbled in the face of local opposition in 2011. Utilities around the U.S. now sue the federal government every year to recoup their storage expenses because the Department of Energy has not come through on its promise. The lawsuits cost taxpayers $2 million a day, according to Camargo. "It's so safe that it's almost a problem," Camargo said. "It's not a priority to a lot of folks to move it." "The Trump administration's Department of Energy wants to create 'campuses' in several states to store waste," the article points out, "and, in exchange, give local jurisdictions funding to develop different aspects of the nuclear cycle — such as fuel creation, power generation and potentially fuel recycling..." "The administration wants to address the fact that waste is sitting at 80 reactor sites around the country. It also needs places for waste from new reactors it wants to build."

The U.S. Department of Energy has approved a $1.9 billion loan to NextEra Energy to restart Iowa's shuttered Duane Arnold nuclear plant, which Google has backed as a power source for its growing AI infrastructure. "The sizable loan is the second of its kind, suggesting that the Trump administration views revived nuclear power as a key source of electricity for tech companies seeking to power their AI data centers," notes TechCrunch. From the report: James Danly, Deputy Secretary of Energy, said that the Iowa power plant's restart in 2029 will "drive down electricity costs," though he did not explain how. Just 50 megawatts will be set aside for the local power cooperative, NextEra CEO John Ketchum said during an earnings call (PDF) last year. That capacity would cover 18% of Iowa's demand growth since 2021, the year before ChatGPT was released. Google is reportedly looking to build up to six data centers near the Duane Arnold Energy Center, which hasn't operated since 2020 when an intense rainstorm damaged the power plant. Rather than repair it, NextEra decided to mothball it. At the time, cheap natural gas was flooding the market, making nuclear power economically unappealing. A lot has changed in the last six years, though. After decades of little growth in demand, the sudden rise of AI coupled with broader electrification of the economy meant that utilities and power providers were suddenly scrambling to find new generating sources of electricity. New data centers are expected to nearly triple the sector's electricity demand by 2035.

The EV blog Electrek reports: A Clinton Township, Michigan man was charged $418 for a single EV charging session at Elder Hyundai's Macomb Township store after finding the charger listed as publicly available on the EVgo app, but didn't discover the charges until after wrapping up his 40-ish minute charging session. "I was flabbergasted," explained Stanley Kpenkann, who had been driving a rented Chevy Bolt EV at the time. "Never in my wildest dreams did I think I would be saddled with a bill of $418 for a charging session." After calling EVgo to report the error, he found that the exorbitant charge wasn't a mistake at all - Elder Hyundai was charging customers an eye-gouging $5 per kWh, plus another $5 for every minute connected. A local news report notes that "After back-and-forth with EVgo, the company processed what it called a goodwill refund of $405." (And the dealership argued their charger was reserved for its own customers and vehicles, so they set prices high to deter outside use.) But Electrek argues the story "speaks to much larger problems among the EV charging business in particular and car dealerships in general..." [In June] Plug & Play EV's Steve Birkett took to LinkedIn to call out his local Hyundai dealer in Union, NJ for charging a ridiculous $15 per kWh to top off his IONIQ 5 (!)... Even worse, he noted that a number of area dealerships that had listed their ports as "public" were actively discouraging public use with signs and stickers designed to turn people away... [U]nlike gas stations, EV charge point operators in many states aren't required to clearly advertise what they'll charge before a driver plugs in in the same way that gas stations are: with clearly legible signage that's visible from the street.

A new study published Friday in AGU Advances "depicts the most advanced picture yet of how a rare but massive solar storm could affect some US industries and electric systems more than others," reports CNN. "During a 250-year solar storm, the East Coast would have widespread potential for grid failure." Researchers modeled what a Carrington Event — a 1-in-150-year geomagnetic storm or even rarer — could mean for the modern day. They estimate the US economy would lose about $1.5 billion to $2 billion per day from direct and indirect costs, as millions of people face power outages. The findings show the most vulnerable areas are the Northeast and the Northern Plains, especially locations at higher latitudes. No one knows when the next big storm will hit. While the most severe geomagnetic storms are labeled as once-in-a-century or rarer, these events don't follow a fixed schedule. "That timing only averages out on very long timescales," said Anna Kelbert, a geophysicist at the Harvard-Smithsonian Center for Astrophysics, who was not involved in the study but previously studied solar storm effects on power grids. "The event can occur at any time, as soon as a week from now, or centuries later...." [Shawn Dahl, service coordinator at the Space Weather Prediction Center operated by the National Oceanic and Atmospheric Administration in Boulder, Colorado], said the sun is now coming down from a period of heightened activity, which is also when some of the biggest storms to hit Earth have occurred in the past. "We still need a lot of work to be ready...." "We haven't really seen events like this size in the modern era, where we've had all of this high technology and we've had the power grid of this size," said Ed Oughton, researcher at George Mason University and lead author of the new study... Because the US grid's actual structure is proprietary for security reasons, the team used engineering models to create various network and transformer setups including the 10,464 substations and 16,256 transmission lines found across the country... The grid structure also contributes to higher risk in some areas. For instance, the eastern US is linked together in a single grid interconnection. A voltage issue in Maine, if not isolated early, could cascade through the grid to Washington, DC. The West works similarly, whereas the Texas interconnection operates mostly within the state... Power is restored over time depending on any alternative electrical paths that could bypass the substation or availabilities of spare transformers, for instance. "This nationwide analysis shows that we are currently ill-prepared to face a major magnetic storm, and that the societal impacts would be catastrophic," Kelbert said. "The study estimates power disruptions for 5.1 million people and 135,000 businesses," according to the article, and "The outages could last from hours to days to weeks depending on the damage and resources available to get back online, said Oughton."
