An anonymous reader shared this report from the Kyiv Independent: The United States will partner with Ukraine to transition Ukraine's coal-fired plants to small modular nuclear reactors, and to use them to help decarbonize its steel industry, the countries announced on November 16 at the U.N. Climate Change Conference in Baku, Azerbaijan... The partnership will build a roadmap and provide technical support to "rebuild, modernize, and decarbonize Ukraine's steel industry with small modular reactors," according to a statement from the U.S. State Department... It will also "facilitate the transition of Ukraine's coal-fired power plants to secure and safe SMR nuclear power plants utilizing existing infrastructure and retraining the workforce," the statement read. Another project announced at the conference, known as COP29, will build a pilot plant in Ukraine to demonstrate production of clean hydrogen and ammonia using simulated small modular reactor technology. That clean hydrogen/ammonia project involves a multinational public-private consortium which also includes Japan and South Korea, according to the U.S. State Department. Their announcement says the three projects "will help position Ukraine to take a leadership role on secure and safe nuclear energy" (as well as industrial decarbonization). Three years ago the U.S. State Department launched a program to help countries develop nuclear energy programs "to support clean energy goals under the highest international standards for nuclear safety, security, and nonproliferation." That program will send $30 million for these three projects...

Datacenter operators are increasingly turning to small modular reactors (SMRs) like those developed by Oklo to meet growing energy demands. According to The Register, Oklo has secured commitments from two major datacenter providers for 750 MW of power, pending regulatory approvals. It brings the firm's planned nuclear build-out to 2.1 gigawatts. From the report: Oklo's designs are, from what we understand, inspired by the Experimental Breeder Reactor II (EBR-II) and utilize liquid-metal cooling. They are capable of producing between 15MW and 50MW of power, depending on the configuration. That means Oklo's datacenter customers plan to deploy somewhere between 15 and 50 of the reactors to satisfy their thirst for electricity. However, they may be waiting a while. According to Oklo's website, the nuclear startup hopes to bring its first plant online before the end of the decade. Before that can happen, though, Oklo will need to obtain approval from the Nuclear Regulatory Commission -- something for which it says it's already submitted applications. In 2022, the watchdog rejected an Oklo plan to build a small atomic reactor in Idaho, citing "significant information gaps" on safety-related measures. That said, Oklo has lately received support from US government agencies including the Department of Energy (DoE), which has awarded a site use permit, while Idaho National Laboratory -- home of EBR-II -- has provided fuel material to support the efforts. Speaking of fuel, Oklo's designs may not suffer from the challenges other SMR startups, like Terrapower, have encountered. Oklo's designs are intended to run on recycled nuclear waste products from traditional reactors. In fact, the startup is currently working with DoE national labs to develop new fuel recycling technologies. Oklo hopes to bring a commercial-scale recycling plan online by the early 2030s.

Renew Home says they're building a "virtual power plant" in Texas by "enabling homes to easily reduce and shift the timing of energy use." Thursday they announced a 10-year project distributing hundreds of thousands of smart thermostats to customers of Texas-based power utility NRG Energy, starting next spring. (Bloomberg calls them "AI-enabled thermostats that use Alphabet Inc.'s Google Cloud technology.") The ultimate goal? "Create a nearly 1-gigawatt, AI-powered virtual power plant" — equivalent to 1.9 million solar panels, enough to power about 200,000 homes during peak demand. One NRG executive touted the move as "cutting-edge, AI-driven solutions that will bolster grid resilience and contribute to a more sustainable future." [Residential virtual power plants] work by aggregating numerous, small-scale distributed energy resources like HVAC systems controlled by smart thermostats and home batteries and coordinating them to balance supply and demand... NRG, in partnership with Renew Home, plans to offer Vivint and Nest smart thermostats, including professional installation, at no cost to eligible customers across NRG's retail electricity providers and plans. These advanced thermostats make subtle automatic HVAC adjustments to help customers shift their energy use to times when electricity is less constrained, less expensive, and cleaner... Over time, the parties expect to add devices like batteries and electric vehicles to the virtual power plant, expanding energy savings opportunities for customers... Through the use of Google Cloud's data, analytics, and AI technology, NRG will be able to do things like better predict weather conditions, forecast wind and solar generation output, and create predictive pricing models, allowing for more efficient production and ultimately ensuring the home energy experience is seamless for customers. Google Cloud will also offer "its AI and machine learning to determine the best time to cool or heat homes," reports Bloomberg, "based on a household's energy usage patterns and ambient temperatures." It was less than a year ago that Renew Home was formed when Google spun off the load-shifting service for its "Google Nest" thermostats, which merged with load-shift management startup OhmConnect. Bloomberg describes this week's announcement as "Three of the biggest names in US home energy automation... coming together to offer some relief to the beleaguered Texas electrical grid." But they point out that 1 gigawatt is roughly 1% of the record summer demand seen in Texas this year. Still, "The entire industry has been built to serve the peak load on the hottest day of the year," said Rasesh Patel, president of NRG's consumer unit. "This allows us to be a lot more smarter about demand in shaving the peak."

Wednesday Cuba was hit by a major hurricane which took down its entire power grid again, this time for about 24 hours, according to CNN: Videos of the aftermath showed power infrastructure turned into a mangled mess and power poles down on streets. Hundreds of technicians were mobilized Thursday to reestablish power connections, according to state media... Operations at two electrical plants were partially restored and parts of eastern and central Cuba had electricity back up by Thursday afternoon, state media reported... The country's power grid has collapsed multiple times, including when Hurricane Oscar hit in October and killed at least 7 people. In the capital of Havana, where 2 million people live, power had been restored to less than 20% of the city by late Friday afternoon, . "Authorities had not yet given an estimate for when power would be fully restored..." Then tonight, CNN reported: A 6.8 magnitude earthquake struck off the coast of eastern Cuba on Sunday, causing material damage in several regions as the island continues to recover from widespread blackouts and the impact of two hurricanes over the past few weeks. The earthquake was reported about 39 km (24 miles) south of Bartolomé Masó before noon local time, about an hour after a 5.9 magnitude quake rocked the area, the United States Geological Survey (USGS) said. "There have been landslides, damage to homes and power lines," Cuban President Miguel Díaz-Canel said, adding that authorities are evaluating the situation to start recovery efforts.

Sodium-ion batteries are cheaper than lithium-ion batteries — and they're also more environmentally friendly. And "In the past few years, sodium-ion battery production has increased in the United States," reports the Washington Post, with a new factory planned to manufacture them "in the same way as lithium-ion batteries, just with different ingredients. Instead of using expensive materials like lithium, nickel and cobalt, these will be made of sodium, iron and manganese..." Last month, sodium-ion battery manufacturer Natron Energy announced it would open a "gigafactory" in North Carolina that would produce 24 gigawatt hours of batteries annually, enough energy to charge 24,000 electric vehicles. But sodium-ion batteries are still early in their development compared with lithium-ion, and they have yet to hit the market on a massive scale. "It's unlikely sodium-ion could displace lithium-ion anytime soon," said Keith Beers, polymer science and materials chemistry principal engineer at technical consultancy firm Exponent... The biggest limitation of sodium-ion batteries is their weight. Sodium weighs nearly three times as much as lithium, and it cannot store the same amount of energy. As a result, sodium-ion batteries tend to be larger. Jens Peters, an economics professor at the University of Alcalá in Madrid, said the energy density could be improved over time in sodium-ion batteries. But, he added, "what we found out so far in our assessments is that it is not a game changer." Sodium-ion batteries are touted to be the environmentally friendly alternative to their lithium-ion counterparts, thanks to their raw materials. Sodium, iron and manganese are all abundant elements on the planet, so they require less energy to extract and cost less... Sodium-ion batteries also last longer than lithium-ion ones because they can withstand more charge cycles, said Wendell Brooks, co-CEO of Natron Energy. "Our product can have millions of cycles," said Brooks, "where lithium-ion would have three to five thousand cycles and wear out a lot faster...." Sodium-ion batteries aren't the best fit for smartphones or electric vehicles, which need to store lots of energy. However, one advantage is their low cost. And they could be a good candidate in situations where the size of the battery isn't a concern, like energy storage. "When something is built out to support grid or backup storage, it doesn't need to be very dense. It's staying put," Beers said. Natron will invest nearly $1.4 billion in the factory "to meet the rapidly expanding demand for critical power, industrial and grid energy storage solutions," according to their announcement. "Natron's high-performance sodium-ion batteries outperform lithium-ion batteries in power density and recharging speed, do not require lithium, cobalt, copper, or nickel, and are non-flammable... Natron's batteries are the only UL-listed sodium-ion batteries on the market today, and will be delivered to a wide range of customer end markets in the industrial power space, including data centers, mobility, EV fast charging, microgrids, and telecom, among others."

An anonymous reader shares a report: Tucked inside a 32-page earnings report, oil and gas giant BP revealed it was killing 18 early-stage hydrogen projects, a move that could have a chilling effect on the nascent hydrogen industry. The decision, along with the sale of the company's U.S. on-shore wind power operations, will save BP $200 million annually and help boost its bottom line. The hydrogen industry, which has relied on oil and gas companies both financially and through lobbying efforts, is preparing for a grimmer outcome. BP has been a supporter of hydrogen. The company's venture capital arm has invested in several green hydrogen startups, including Electric Hydrogen and Advanced Ionics. Earlier this year, BP said it would develop "more than 10" hydrogen projects in the U.S., Europe, and Australia. Now, BP is scaling back those plans, saying it'll develop between five and ten projects. The company is keeping quiet about which ones will receive the green light.

The Federal Energy Regulatory Commission (FERC) blocked Amazon's bid to access more power from the Susquehanna nuclear plant for its Pennsylvania data center, citing grid reliability and consumer cost concerns. The Hill reports: In a 2-1 decision, the FERC found the regional grid operator, PJM Interconnection, failed to prove that the changes to the transmission agreement with Susquehanna power plant were necessary. The regulator's two Republican commissioners, Mark Christie and Lindsay See, outvoted Democratic chair Willie Phillips. The chair's two fellow Democratic commissioners, David Rosner and Judy Chang, sat out the vote. "Co-location arrangements of the type presented here present an array of complicated, nuanced and multifaceted issues, which collectively could have huge ramifications for both grid reliability and consumer costs," Christie wrote in a concurring statement. In a dissenting statement, Phillips argued the deal with Amazon "represents a 'first of its kind' co-located load configuration" and that Friday's decision is a "step backward for both electric reliability and national security." "We are on the cusp of a new phase in the energy transition, one that is characterized as much by soaring energy demand, due in large part to AI, as it is by rapid changes in the resource mix," Phillips wrote. Amazon purchased a 960-megawatt data center next to the Susquehanna power plant for $650 million earlier this year. Following the announcement, PJM sought to increase the amount of power running directly to the co-located data center. However, the move faced pushback from regional utilities, including Exelon and American Electric Power (AEP).

An anonymous reader quotes a report from The Guardian: Sweden has vetoed plans for 13 offshore windfarms in the Baltic Sea, citing unacceptable security risks. The country's defence minister, Pal Jonson, said on Monday that the government had rejected plans for all but one of 14 windfarms planned along the east coast. The decision comes after the Swedish armed forces concluded last week that the projects would make it more difficult to defend Nato's newest member. The proposed windfarms would have been located between Aland, the autonomous Finnish region between Sweden and Finland, and the Sound, the strait between southern Sweden and Denmark. The Russian exclave of Kaliningrad is only about 310 miles (500km) from Stockholm. Wind power could affect Sweden's defence capabilities across sensors and radars and make it harder to detect submarines and possible attacks from the air if war broke out, Jonson said. The only project to receive the green light to was Poseidon, which will include as many as 81 wind turbines to produce 5.5 terawatt hours a year off Stenungsund on Sweden's west coast. "Both ballistic robots and also cruise robots are a big problem if you have offshore wind power," Jonson said. "If you have a strong signal detection capability and a radar system that is important, we use the Patriot system for example, there would be negative consequences if there were offshore wind power in the way of the sensors."

"One technology critical to fighting climate change is lagging," reports the Washington Post, "thanks to a combination of high interest rates, rising costs, misinformation and the cycle of home construction. Adoption of heat pumps, one of the primary ways to cut emissions from buildings, has slowed in the United States and stalled in Europe, endangering the switch to clean energy. "Heat pump investment in the United States has dropped by 4 percent in the past two years, even as sales of EVs have almost doubled, according to data from MIT and the Rhodium Group. In 13 European countries, heat pump sales dropped nearly in half in the first half of 2024, putting the European Union off-track for its climate goals." "Many many markets are falling," said Paul Kenny, the director general of the European Heat Pump Association. "It takes time to change people's minds about a heating system." Heat pumps — essentially air conditioners that can also work in reverse, heating a space as well as cooling it — are crucial to making buildings more climate-friendly. Around 60 percent of American homes are still heated with furnaces running on oil, natural gas, or even propane; to cut emissions from homes, all American houses and apartments will need to be powered by electricity... In the United States, experts point to lags in construction, high interest rates, and general belt-tightening from inflation... [Cora Wyent, director of research for the electrification advocacy group Rewiring America] added, heat pumps are still growing as a share of overall heating systems, gaining ground on gas furnaces. In 2023, heat pumps made up 55 percent of all heating systems sold, while gas furnaces made up just 45 percent. "Heat pumps are continuing to increase their total market share," she said. Homeowners may also run into trouble when trying to find contractors to install heat pumps. Barton James, the president and CEO of the Air Conditioning Contractors of America, says many contractors don't have training on how to properly install heat pumps; if they install them incorrectly, the ensuing problems can sour consumers on the technology... In the United States, low gas prices also make the economics of heat pumps more challenging. Gas is around three times cheaper than electricity — while heat pumps make up most of that ground with efficiency, they aren't the most cost-effective option for every household. The Post also spoke to the manager for the carbon-free buildings team at the clean energy think tank RMI. They pointed out that heating systems need to be replaced roughly every 15 years — and the next cycle doesn't start until 2035. The article concludes that "even with government policies and subsidies, many parts of the move to clean energy will require individual people to make changes to their lives. According to the International Energy Agency, the number of heat pumps will have to triple by 2030 to stay on track with climate goals. The only way to do that, experts say, is if incentives, personal beliefs, and technology all align."

The Washington Post reports that a former Etsy CEO remodeled their home into what's known as a passive house. It's "designed to be as energy efficient as possible, typically with top-notch insulation and a perfect seal that prevents outside air from penetrating the home; air flows in and out through filtration and exhaust systems only." Their benefits include protection from pollution and pollen, noise insulation and a stable indoor temperature that minimizes energy needs. That translates to long-term savings on heating and cooling. While the concept has been around for about 50 years, experts say that the United States is on the cusp of a passive house boom, driven by lowered costs, state-level energy code changes and a general greater awareness of — and desire for — more sustainable housing... Massachusetts — which alongside New York and Pennsylvania is one of the leading states in passive house adoption — has 272 passive house projects underway thanks to an incentive program, says Zack Semke [the director of the Passive House Accelerator, a group of industry professionals who aim to spread lessons in passive house building]. Consumer demand for passive houses is also increasing, says Michael Ingui, an architect in New York City and the founder of the Passive House Accelerator... The need to lower our energy footprint is so much more top-of-mind today than it was 10 years ago, Ingui says, and covid taught us about the importance of good ventilation and filtered fresh air. "People are searching for the healthiest house," he says, "and that's a passive house...." These days, new passive houses are usually large, multifamily apartment buildings or high-end single-family homes. But that leaves out a large swath of homeowners in the middle. To widen passive house accessibility to include all types of people and their housing needs, we need better energy codes and even more policies and incentives, says In Cho, a sustainability architect, educator and a co-founder of the nonprofit Passive House for Everyone! Passive houses "can and should serve folks from all socioeconomic backgrounds," she says. Using a one-two punch of mandates for energy efficient buildings and greater awareness to the public, that increased demand for passive houses will lead to more supply, Cho says. And we're already seeing those changes in the market. Take triple-pane windows, for example, which are higher performing and more insulating than their double-pane counterparts. Even just 10 to 20 years ago, the difference in price between the two was high enough to make triple-pane windows cost-prohibitive for a lot of people, Cho says. Over the years, as the benefits of higher performing windows became more well-known, and as cities and states changed their energy codes, more companies began producing better windows. Now they're basically at price parity, she says. If we keep pushing for greater awareness and further policy changes, it's possible that all of the components of passive house buildings could follow that trend. "For large multifamily projects, we're already seeing price parity in some cases, Semke says... "But as it stands, single-family passive houses are still likely to cost a margin more than non-passive houses, he says. This is because price parity is easier to achieve when working at larger scales, but also because many of the housing policies and incentives encouraging passive house buildings are geared toward these larger projects."

While Amazon, Google, and other companies build new data centers — sometimes for their AI projects — parts of America "are facing higher electric bills," reports the Washington Post: The facilities' extraordinary demand for electricity to power and cool computers inside can drive up the price local utilities pay for energy and require significant improvements to electric grid transmission systems. As a result, costs have already begun going up for customers — or are about to in the near future, according to utility planning documents and energy industry analysts. Some regulators are concerned that the tech companies aren't paying their fair share, while leaving customers from homeowners to small businesses on the hook. In Oregon, electric utilities are warning regulators that consumers need protections from rising rates caused by data centers. From Virginia to Ohio and South Carolina, companies are battling over the extent of their responsibility for increases, attempting to fend off anger from customers. In the Mid-Atlantic, the regional power grid's energy costs shot up dramatically, and data centers are cited as among root causes of rate increases of up to 20 percent expected in 2025... The tech firms and several of the power companies serving them strongly deny they are burdening others. They say higher utility bills are paying for overdue improvements to the power grid that benefit all customers. In some cases, they said in response to criticism from consumer and business advocates that they are committed to covering additional costs. But regulators — and even some utilities — are growing skeptical. A jarring example of fallout on consumers is playing out on the Mid-Atlantic regional power grid, called PJM Interconnection, which serves 13 states and D.C. The recent auction to secure power for the grid during periods of extreme weather and high demand resulted in an 800 percent jump in the price that the grid's member utilities had to pay. The impact will be felt by millions by the spring, according to public records. Power bills will increase as much as 20 percent for customers of a dozen utilities in Maryland, Ohio, Pennsylvania, New Jersey and West Virginia, regulatory filings show. That includes households in the Baltimore area, where annual bills will increase an average of $192, said Maryland People's Counsel David Lapp, a state appointee who monitors utilities. The next auction, in 2025, could be more painful, Lapp said, leaving customers potentially "looking at increases of as much as $40 to $50 a month...." Advocates cite another source of cost-shifting onto consumers: discounted rates that power companies and local government officials use to entice tech companies to build data centers... Google worked out a deal with Dominion Energy, blessed by regulators, to pay 6 cents per kilowatt hour for its power. That is less than half of what residential customers pay, as well as substantially less than is paid by businesses... The article points out that in Pennsylvania, "Amazon's novel plan to fuel a data center from a reactor at the nearby Susquehanna nuclear plant is now in jeopardy, after regulators blocked it Friday. They cited potential impact on consumers as among their concerns. The plan threatens to leave other ratepayers stuck with a bill of $50 million to $140 million, according to testimony from [power utility] AEP and utility conglomerate Exelon." And meanwhile, one Virginia retiree complained about a proposed $54 million transmission line and substation for an Amazon data center. "They are already making money hand over fist, and now they want us to pay for this?

An anonymous reader quotes a report from The Guardian: The cost of cleaning up Sellafield is expected to spiral to 136 billion pounds ($175 billion USD) and Europe's biggest nuclear waste dump cannot show how it offers taxpayers value for money, the public spending watchdog has said. Projects to fix buildings containing hazardous and radioactive material at the state-owned site on the Cumbrian coast are running years late and over budget. Sellafield's spending is so vast -- with costs of more than 2.7 billion pounds a year -- that it is causing tension with the Treasury, the report from the National Audit Office (NAO) suggests. Officials from finance ministry told the NAO it was "not always clear" how Sellafield made decisions, the report reveals. Criticisms of its costs and processes come as the chancellor, Rachel Reeves, prepares to plug a hole of about 40 billion pounds in her maiden budget. Gareth Davies, the head of the NAO, said: "Despite progress achieved since the NAO last reported, I cannot conclude Sellafield is achieving value for money yet, as large projects are being delivered later than planned and at higher cost, alongside slower progress in reducing multiple risks." He added: "Continued underperformance will mean the cost of decommissioning will increase considerably, and 'intolerable risks' will persist for longer." David Peattie, the NDA's chief executive, said: "Sellafield is one of the most complex environmental programs in the world. We're proud of our workforce and achievements being made, including the unprecedented retrieval of legacy waste from all four highest hazard facilities. But as the NAO rightly points out there is still more to be done. This includes better demonstrating we are delivering value for money and the wider significant societal and economic benefits through jobs, the supply chain and community investments."

"The world's largest renewable energy and transmission project has received key approval from government officials," reports New Atlas. Solar power from Australia will be carried 2,672 miles (4,300 kilometers) to Singapore over undersea cables in what's being called "the Australia-Asia Power Link project." Reuters reports that SunCable "aims to produce 6 gigawatts of electricity at a vast solar farm in Northern Australia and ship about a third of that to Singapore via undersea cable." More from New Atlas: [The project] will start by constructing a mammoth solar farm in Australia's Northern Territory to transmit around-the-clock clean power to [the Australian city] Darwin, and also export "reliable, cost-competitive renewable energy" to Singapore... with a clean energy generation capacity of up to 10 gigawatts, plus utility scale onsite storage. [The recently-obtained environmental approval] also green lights an 800-km (~500-mile) overhead transmission line between the solar precinct and Murrumujuk near Darwin... If all of the dominoes line up perfectly, supply of the first clean electricity is estimated to start in the early 2030s. An overview graphic on the project page shows that the eventual end game for the Powell Creek development appears to be the generation of up to 20 GW of peak solar power and have some 36-42 GWh of battery storage on site.

PV Magazine reports: Researchers in Australia and China have developed an innovative technology enabling direct lithium extraction from difficult-to-process sources like saltwater, which they say represents a substantial portion of the world's lithium potential. Until now, up to 75% of the world's lithium-rich saltwater sources have remained untapped because of technical limitations, but given predictions that global lithium supply could fall short of demand as early as 2025, the researchers believe they have a game-changing solution. Their technology is a type of nanofiltration system that uses ethylenediaminetetraacetic acid, or EDTA, as a chelating agent to selectively separate lithium from other minerals, especially magnesium, which is often present in brines and difficult to remove. "With some predicting global lithium supply could fall short of demand as early as 2025, the innovative technology sets a new standard in lithium processing," writes SciTechDaily: The work, co-led by Dr Zhikao Li, from the Monash Suzhou Research Institute and the Department of Chemical and Biological Engineering, and Professor Xiwang Zhang from the University of Queensland, promises to meet the surging demand for lithium and paves the way for more sustainable and efficient extraction practices... "Our technology achieves 90 percent lithium recovery, nearly double the performance of traditional methods, while dramatically reducing the time required for extraction from years to mere weeks," Dr. Li said. The technology also turns leftover magnesium into a valuable, high-quality product that can be sold, reducing waste and its impact on the environment. Beyond its advanced efficiency, the EALNF system brings innovation to address major environmental concerns associated with lithium extraction. Unlike conventional methods that deplete vital water resources in arid regions, the technology produces freshwater as a by-product. Dr Li said the system was flexible and ready for large-scale use, meaning it can quickly expand from testing to full industrial operations. "This breakthrough is crucial for avoiding a future lithium shortage, making it possible to access lithium from hard-to-reach sources and helping power the shift to clean energy." "Our scalable process minimizes environmental impact while maximizing resource utilization," according to the researchers' article in Nature Sustainability, "thereby catalysing the shift toward a more sustainable future."

Researchers at the United States Geological Survey and the Arkansas government announced on Monday that they had found a trove of lithium, a critical raw material for electric vehicle batteries, in an underground brine reservoir in Arkansas. From a report: With the help of water testing and machine learning, the researchers determined that there might be five million to 19 million tons of lithium -- more than enough to meet all of the world's demand for the metal -- in a geological area known as the Smackover Formation. Several companies, including Exxon Mobil, are developing projects in Arkansas to produce lithium, which is dissolved in underground brine. Energy and mining companies have long produced oil, gas and other natural resources in the Smackover, which extends from Texas to Florida. And the federal and state researchers said lithium could be extracted from the waste stream of the brines from which companies extracted other forms of energy and elements. The energy industry, with the Biden administration's encouragement, has been increasingly working to produce the raw materials needed for the lithium-ion batteries in the United States. A few projects have started recently, and many more are in various stages of study and development across the country. Most of the world's lithium is produced in Australia and South America. A large majority of it is then processed in China, which also dominates the manufacturing of electric vehicle batteries. "The potential for increased U.S. production to replace imports has implications for employment, manufacturing and supply chain resilience," David Applegate, the director of the United States Geological Survey, said in a statement announcing the study. "This study illustrates the value of science in addressing economically important issues."

"Millions of Cubans remained without power for a third day in a row Sunday," reports CNN, "after fresh attempts to restore electricity failed overnight and the power grid collapsed for the fourth time — all before the arrival of Hurricane Oscar." A report from Reuters notes it was the fourth power grid failure in 48 hours. "On the forecast track, the center of Oscar is expected to continue moving across eastern Cuba tonight and Monday, then emerge off the northern coast of Cuba late Monday and cross the central Bahamas on Tuesday," the U.S. National Hurricane Center said. The Communist-run government canceled school through Wednesday — a near unprecedented move in Cuba — citing the hurricane and the ongoing energy crisis... Cuba had restored power to 160,000 clients in Havana just prior to the grid's Sunday collapse, giving some residents a glimmer of hope... Energy and mines minister Vicente de la O Levy told reporters earlier on Sunday he expected the grid to be fully functional by Monday or Tuesday but warned residents not to expect dramatic improvements. It was not immediately clear how much the latest setback would delay the government's efforts.

"A technology pioneered by Benjamin Franklin is being revived to build more efficient electric motors," reports the Wall Street Journal, "an effort in its nascent stage that has the potential to be massive." A handful of scientists and engineers — armed with materials and techniques unimaginable in the 1700s — are creating modern versions of Franklin's "electrostatic motor," that are on the cusp of commercialization... Franklin's "electrostatic motor" uses alternating positive and negative charges — the same kind that make your socks stick together after they come out of the dryer — to spin an axle, and doesn't rely on a flow of current like conventional electric motors. Every few years, an eager Ph.D. student or engineer rediscovers this historical curiosity. But other than applications in tiny pumps and actuators etched on microchips, where this technology has been in use for decades, their work hasn't made it out of the lab. Electrostatic motors have several potentially huge advantages over regular motors. They are up to 80% more efficient than conventional motors after all the dependencies of regular electric motors are added in. They could also allow new kinds of control and precision in robots, where they could function more like our muscles. And they don't use rare-earth elements because they don't have permanent magnets, and require as little as 5% as much copper as a conventional motor. Both materials have become increasingly scarce and expensive over the past decade, and supply chains for them are dominated by China. "It's reminiscent of the early 1990s, when Sony began to produce and sell the first rechargeable lithium-ion batteries, a breakthrough that's now ubiquitous..." according to the article. "These motors could lead to more efficient air-conditioning systems, factories, logistics hubs and data centers, and — since they can double as generators — better ways of generating renewable energy. They might even show up in tiny surveillance drones." And the article points out that C-Motive Technologies, a 16-person startup in Wisconsin, is already "reaching out to companies, hoping to get their motors out into the real world." ("So far, FedEx and Rockwell Automation, the century-old supplier of automation to factories, are among those testing their motors.") C-Motive's founders discovered that a number of technologies had matured enough that, when combined, could yield electrostatic motors competitive with conventional ones. These enabling technologies include super fast-switching power electronics — like those in modern electric vehicles — that can toggle elements of the motor between states of positive and negative charge very quickly... Dogged exploration of combinations of various readily available industrial organic fluids led to a proprietary mix that can both multiply the strength of the electric field and insulate the motor's spinning parts from each other — all without adding too much friction — says C-Motive Chief Executive Matt Maroon.

A California oil refinery that produces 8% of the state's gasoline is shutting down late next year — a decision the Los Angeles Times says is "driven by climate change, the transition to electric vehicles and demands for cleaner air." "There's no question we are going to lose refineries over time, because demand is going to go down as we transition to electric vehicles, but I did not expect to see any of them exiting this quickly," said Severin Borenstein, faculty director of the Energy Institute at UC Berkeley's Haas School of Business. California "over the medium term" will have to rely more on imports, he said. "I think part of the response the state's going to need to consider is how to make sure that we can import sufficient gasoline to meet our needs...." David Hackett, chairman of Stillwater Associates, an Irvine oil consultancy, said he was contacted by Phillips just before the announcement, and was told the closure was a business decision. He said that although the timing was somewhat surprising, the closure wasn't, given the age of the refineries, their relatively small size and the inefficient layout that connects them by a pipeline. "That plant has been for sale for years. It hasn't found any buyers and I think that this has been an economic decision on their part. They looked at the profitability of the place and compared it with the other businesses that they have, and it didn't make the cut," he said. "The closure is likely to increase California's already high prices at the gas pump, given that much of the replacement gasoline will be shipped in by ocean vessel, analysts say..." according to another article from the Los Angeles Times. "Environmentalists and community activists cheered the news, however, saying it will mean cleaner air for the thousands who live in the area and that the state must continue the transition away from its dependence on fossil fuels."

The Miami Herald reports: Cuba's electrical grid shut down again early Saturday, leaving the island without electricity after authorities tried but failed to restore power following an earlier nationwide blackout on Friday. The island's Electric Union reported a second "total outage" at 6:15 a.m., just hours after officials reported they had restored power in a few "microsystems" all over the island... The country has been going through its worst economic crisis since the fall of the Soviet Union, and the government lacks money to buy oil in the international market to meet domestic demand. Cubans irked by the daily blackouts defied the country's Draconian laws punishing criticism of the government and left several comments in official news outlets calling for government officials to resign. The second outage will likely exacerbate public frustration as food begins to spoil because of the lack of refrigeration. Two hours ago, Reuters reported that Cuba's government "said on Saturday it had made some progress in gradually re-establishing electrical service across the island, including to hospitals and parts of the capital Havana..." "Most of Cuba's 10 million people, however, remained without electricity on Saturday afternoon." Traffic lights were dark at intersections throughout Havana, and most commerce was halted... Cuban officials have said even if the immediate grid collapse is resolved, the electricity crisis will continue. Cuba produces little of its own crude oil, and fuel deliveries to the island have dropped significantly this year, as Venezuela, Russia and Mexico, once important suppliers, have reduced their exports to Cuba. Mexico experienced a historic drop in production, according to the New York Times, while Venezuela is selling its oil to foreign companies to ease its own economic crisis: The experts had warned for years: Cuba's power grid was on the verge of collapse, relying on plants nearly a half-century old and importing fuel that the cash strapped Communist government could barely afford... Cuban economists and foreign analysts blamed the crisis on several factors: the government's failure to tackle the island's aging infrastructure; the decline in fuel supplies from Venezuela, Mexico and Russia; and a lack of capital investment in badly needed renewable systems, such as wind and solar. Jorge Piñon, a Cuban-born energy expert at the University of Texas at Austin, highlighted that Cuba's electricity grid relies on eight very large power plants that are close to 50 years old. "They have not received any operational maintenance much less capital maintenance in the last 12 to 15 years," he said, adding that they have a lifetime of only 25-30 years. "So, number one, it's a structural problem, they are breaking down all the time and that has a domino effect," he said. Compounding the problems, Cuba burns crude oil as a fuel for its plants. Experts said Cuba's own crude oil production is very heavy in sulfur and metals that can impair the thermoelectric combustion process. "So they have to be constantly repairing them, and they're repairing them with Band-Aids," said Mr. Piñon... "If they can't turn these plants back on there is a concern that this could turn into another mass exodus," said Ricardo Herrero, the director of the Cuba Study Group in Washington. "They are really short on options," he added.

Cuba's power grid failed on Friday, leaving 10 million people without electricity. NPR reports: One of the country's largest power plants, the Antonio Guiteras power plant in the western province of Matanzas, failed shortly before midday on Friday. The failure prompted a total breakdown of Cuba's electrical system. The power outage comes after days of rolling blackouts. Cuba's prime minister, Manuel Marrero Cruz, blamed the problem on deteriorating infrastructure and fuel shortages exacerbated by Hurricane Milton, which has made it difficult for fuel deliveries to reach the island. The prime minister made an address on state television on Thursday evening and said the government would prioritize providing electricity to residential areas and promised shipments of fuel would arrive on the island in the coming days. Cuban officials have not indicated a timeline for when the power grid will be operational again. The massive blackout is a new low in a country that has already been dealing with a deepening economic crisis and widespread food shortages.
