Twenty-six House Republicans may have just put big green targets on their own backs.
Last month, the House passed a bill that would have raised the debt ceiling while also repealing most of the tax credits for clean energy projects enacted in last year’s Inflation Reduction Act. That provision was a poison pill for President Biden and congressional Democrats, and was jettisoned in the final deal between the White House and Congress to lift the debt limit.
But it also opened up a number of Republicans to political attacks for voting to jeopardize green jobs in their own districts. It’s a sign of just how far climate politics have shifted, in part due to the political strategy underlying Green Bidenomics.
This is a new dynamic. Back in 2009, House Democrats spent months laboring over major climate legislation. They ultimately narrowly passed the American Clean Energy and Security Act (also known as “Waxman-Markey”), a cap-and-trade program to curb greenhouse gas emissions. But despite a Democratic supermajority in the Senate, the bill was dead-on-arrival in the upper chamber, which never even took it up for a vote.
The House vote became a massive political albatross for Democrats in the 2010 midterm election — vulnerable members had “walk[ed] the plank,” as former Rep. Tom Periello put it. Republicans wielded Waxman-Markey as a cudgel, branding the shelved climate plan a “cap-and-tax” job killer — a lethal hit in an extremely weak post-Great Recession economy. Ultimately, more than two dozen Democrats who voted in favor of the cap-and-trade bill were wiped out that November as Republicans took back the House.
Badly burned, Democrats shifted course when they next had the opportunity to craft climate legislation. Where Waxman-Markey aimed to fight climate change by penalizing emissions, Biden’s Inflation Reduction Act does so by subsidizing renewables. It largely steered clear of carbon taxes, instead centering gigantic subsidy carrots that “crowd in” private sector investment for clean energy development.
The IRA also embraced green industrial strategy, ensuring that as much of the clean energy supply chain as possible is produced at home — battery manufacturers, EV plants, and the like. That has drastically shifted the politics: while traditional cap-and-trade emissions reductions plans were tarred as job killers, green Bidenomics is a clear job creator. Since the IRA was enacted, clean energy companies have already added 100,000 new jobs. Another 46 new clean energy manufacturing facilities have been announced, creating upwards of 18,000 anticipated jobs. Those numbers will only grow over the coming years.
Aligning that kind of economic muscle with the climate change fight has made the IRA politically resilient. It has left even right-wing agitators like Representative Marjorie Taylor Greene – in whose district the solar company QCells is investing $2.5 billion to create 2,500 jobs – tying themselves in knots to simultaneously cheer new in-district investment while voicing opposition to the federal incentives behind it.
It’s also why Republicans backed down during debt ceiling negotiations and let the clean energy tax credits survive. But not before the far-right House Freedom Caucus forced all of them to take a toxic vote against green jobs. As CNN reported, “More than two dozen House Republicans who recently welcomed multi-million-dollar clean energy manufacturing investments in their districts voted … to repeal the tax incentives that stimulated those very same projects.”
That could come back to haunt some of those Republicans, especially the frontline “majority makers” who won seats in districts that Biden carried. For instance, freshman Representative Marc Molinaro in New York’s 19th congressional district eked out a 2-point win in a district that Biden carried by nearly 5 points. Molinaro voted for the repeal bill even though the IRA is bringing a new long-duration battery plant from Zinc8 Energy Solutions — and 500 jobs for his constituents — to his district.
Molinaro is already feeling the heat from that vote. He’s facing a potential rematch against his 2022 opponent, Democrat Josh Riley. And in an op-ed, Riley called Molinaro’s vote a “gut punch to folks who have experienced the ups-and-downs in our local economy.” Under the IRA, Riley said, upstate New York could grow into a “Valley of Opportunity where folks can earn a place in the Middle Class manufacturing the things we need to save the planet.” Yet their own member of Congress cast a vote to quash that growth: “[I]nstead of supporting those investments,” Riley wrote, “Molinaro called them a ‘bad idea,’ and he derided them as ‘reckless spending.’”
More Republicans could find themselves on the hot seat. Others who won close races or represent Biden-voting districts — like Lauren Boebert of Colorado (whose district will be home to “the world’s largest manufacturing plant for wind turbine towers”) and Juan Ciscomani of Arizona — could soon hear from opponents and voters about why they tried to undermine investments in their communities.
It’s never good politics to cast a vote that might take jobs away from your constituents. Fairly or not, that was the hit on Democrats who tried to take climate action in 2009. But the shoe is on the other foot now, and the political albatross is around those who flirted with undoing the biggest climate law the United States has ever passed. Green Bidenomics is good political economy, and it’s rapidly shifting the terms of debate in America.

Lunar Energy’s latest AI-powered system aims to integrate EVs into the automated demand response mix.
In theory, it’s straightforward to assemble the smart energy home: Solar panels, home backup batteries, and electric vehicles, plus smart thermostats, heat pumps, and water heaters — all the individual pieces can be had for the homeowner who can afford the up-front cost. The challenge is getting all those pieces to talk to one another.
Bay Area-based Lunar Energy is one of the tech firms that’s been trying to crack this problem. Today, it announced an upgraded version of its artificial intelligence-powered home energy control system, which not only integrates all those separate systems but also responds tactically to energy markets. CEO Kunal Girotra told me Lunar AI saves its users money by monitoring their home 24/7 and making decisions to charge, not to charge, or discharge so that they save the most money.
“Utilities are all moving to almost-real-time changes of rates,” he said. “You need software to handle that for you. I think that the race is on for who has the best AI machine learning algorithms to save the most amount of money. And so far, we seem to have a head start.”
Lunar’s first-generation system focused on generation, storage, and control. In other words, it connected elements like a home’s rooftop solar panels with the backup battery the residents might keep in the garage, using the AI to decide when to meet the home’s real-time energy needs with solar versus grid energy versus stored power. What it didn’t have was the ability to work with electric vehicles to manage charging and use the car’s battery as a bonus source of energy.
To fix this, Lunar has built its own bidirectional EV charger — one that can charge up the battery or discharge the car’s battery for a secondary use, like backing up the home’s power supply. Girotra, formerly the head of Tesla Energy, told me the problem with that functionality to this point has been the connection point between the car and the home electrical system. Carmakers and other companies in the space didn’t have the deep experience with electrical certifications to make the process seamless, he tells me. That led to setups like the original Ford Charge Station Pro, which required several different wall-mounted electrical boxes to connect the F-150 Lightning EV to the home.
Lunar’s charger is built to connect to its customers’ existing home Lunar energy system, which includes a microgrid interconnect device they call Lunar Bridge that islands the home in case of a power outage on the grid. In that way, the power stored in the EV battery is ready to back up the home in case of a blackout without any additional work — or to be optimized as part of a fully smart home that’s making money as part of a virtual power plant.
The company’s setup allows for another fun feature: “slow” charging that’s not slow at all, but actually two or three times as fast as the Level 2 charging most EV owners use to recharge their batteries overnight. Electric cars in the U.S. can typically take on only about 11 kilowatts of AC power from one’s home because of the limitations of their on-board hardware. Because Lunar’s system is fully DC, however, Girotra said the company decided to build a DC home charger, one that — like a Tesla Supercharger or other DC fast chargers out in the world — isn’t limited by that power cap. Lunar said it could use a combination of power from the grid, home solar, or home batteries to charge an EV at up to 25 kilowatts. That’s enough to recharge an EV in three to four hours rather than six to eight.
“If the standards get high, and if everybody sees cars can get charged in three hours, then all of a sudden people are like, ‘Wow, this is how I want it,’” he said. “Especially for 25% of the users who are like me, who always are running low on charge and they don’t mind a boost every now and then.”
Some of the other improvements in the second-gen system are more incremental. An inverter that’s 40% more powerful helps Lunar get its system up to enterprise scale. That’s crucial, as the world moves toward a place where more homes and businesses employ battery backup systems. Lunar’s new batteries come in modular 5 kilowatt-hour blocks ranging from 10 kilowatt-hours to 30 kilowatt-hours in a single unit and scale up to 300 kilowatt-hours for home or small commercial use; there’s also new pad-mounted configurations with capacity up to 1 megawatt-hour.
Batteries, though, are the simple part. Everyone from EV makers like Rivian to utilities like Octopus Energy is racing to make a person’s or a business’s batteries and solar panels and electric cars work for them, using the power of AI to account for moment-to-moment changes in energy prices and supply. Lunar’s new tech makes the case that the most important element is a single brain to integrate every last smart, electrified thing in your house.
The fundraise comes on the heels of a $50 million grant from the Department of Energy.
Almost all lithium-ion batteries on the market rely on graphite for their anodes, more than 90% of which is processed in China. That concentration has created a chokepoint in the Pentagon’s supply chain as the military increasingly turns to batteries to help its transportation network operate more quietly and reduce reliance on complex refueling logistics.
So when Congress passed the latest National Defense Authorization Act at the end of 2025, barring Chinese-linked battery materials from military use starting in 2028, Coreshell saw an opening. While the California-based silicon-anode battery startup had previously focused on automakers as its beachhead customers, it’s now shipping its first battery cells to the military for use on Navy ships and Army ground vehicles. On Wednesday, Coreshell announced a $30 million Series B to scale up manufacturing operations to meet the needs of this growing customer base.
“We’re entering a new stage where we’re no longer, I would say, demand limited,” Coreshell’s CEO Jonathan Tan told me. “This year we’ve had to put on second and third shifts, work nights and weekends, just to get the product out the door.”
Coreshell sets itself apart by going a step further than the NDAA requires. The law doesn’t make suppliers trace battery materials all the way back to the mine, which would be exceedingly difficult given China’s dominance across the battery supply chain. But Coreshell has nevertheless eliminated Chinese sourcing from its anodes by replacing graphite with silicon mined and refined in the U.S. by Ferroglobe, one of its Series A investors.
Ferroglobe and global investment firm Access Industries led the latest round, with defense contractor ADS also joining as a new strategic investor. The financing comes on the heels of a $50 million Department of Energy grant that Coreshell secured in August as part of a program to strengthen the domestic battery supply chain. That funding will support the company’s first commercial-scale facility, a 2-gigawatt-hour factory.
That’s about 20 times the size of the 100-ish-megawatt-hour plant the startup had originally envisioned, as the DOE grant has allowed Coreshell to “expand much further than we were originally expecting,” according to Tan. The company is now evaluating several potential U.S. sites and expects to announce its selection early next year. For now, it relies on unnamed contract manufactures, along with its small pilot line in San Leandro, to produce its cells. But once the gigafactory gets up and running, the startup plans to bring electrode production in house by 2028, followed by full cell assembly in 2029.
Building this plant will ultimately require significant additional capital. But Tan believes this latest vote of confidence from the federal government will help Coreshell to diversify its capital stack as it continues to fundraise. “That’s one of the great things about having such a notable DOE award is that it also allows us to attract multiple forms of capital,” he told me.
Silicon has long been recognized as a promising alternative material for battery anodes, as it can store far more energy than graphite. The catch is that it tends to swell during charging, causing it to break down quickly and ultimately leading to a much shorter cycle life. Coreshell says it’s extended its anode’s lifespan by giving it a proprietary coating, which Tan told me back in April essentially means “painting the inside of your battery” with an ultra-thin protective layer.
Other companies, such as Sila Nanotechnologies and Group14 Technologies, are also working to commercialize silicon anodes. But Coreshell says many of its competitors rely on more highly engineered, expensive forms of silicon, such as silane gas. By contrast, Coreshell uses metallurgical silicon, a cheap, raw commodity already widely used in aluminum alloys. That, Tan argues, gives the company a cost advantage not only over its competitors, but potentially Chinese graphite too.
Coreshell hasn’t yet demonstrated that its cells can meet the performance demands of the automotive industry, however. When the company raised its Series A in early 2025, it said it expected its automotive cells to exceed 1,000 charge cycles while retaining 80% of their original capacity. But Tan told me many defense applications don’t require such demanding performance targets, as Navy ships and ground vehicles are “not intending to have as many miles or missions or use cases on that same battery” as a consumer EV would.
That doesn’t mean the company is abandoning its automotive ambitions. As Tan pointed out, electric vehicles remain by far the largest source of global and domestic battery demand. “It’s natural for us to obviously utilize the security supply chain first,” he told me. “That allowed us to really get to commercialization, revenue, and production faster, because automotive qualification is this longer journey. But ultimately, we want to do both of those and more.”
Current conditions: A large storm is roaring across the Northeast that will shower Michigan and Upstate New York with rain and snow by tomorrow • AccuWeather declared an early end to the 2026 Atlantic hurricane season, which saw 10 named storms and only one hurricane in October, breaking a 121-year record for the latest first hurricane • It’s a mild, cloudy day at the Rethondes Clearing in France’s Forest of Compiègne, where the armistice that ended World War I was signed 108 years ago today.
Inflation is ticking up again, and faster than expected. That’s my colleague Matthew Zeitlin’s read on the latest numbers from the Bureau of Labor Statistics. Preliminary data from Heatmap and MIT’s Electricity Price Hub shows that electricity prices in particular spiked nearly 8% to 19.9 cents per kilowatt-hour in October from 18.5 cents in the same month last year. But that’s largely due to a change in the timing of a bill credit in California. Without that, the year over year price jump was just under 4%.

Ontario Power Generation, the state-owned utility in Canada’s most populous province, admitted in a public filing Wednesday that its megaproject to build the first small modular reactor in the rich world is costing a lot more than planned. The company is constructing the world’s first BWRX-300, the flagship reactor from GE Vernova Hitachi Nuclear Energy, at its Darlington plant. The project is an attempt to revive construction of atomic power stations in North America, Europe, and Japan by building the inevitably costly first-of-a-kind unit that can then be replicated at what the developers say will be a decreasing price. Using billions in Canadian ratepayers’ money to essentially de-risk an American-Japanese technology ruffled some feathers among the country’s nuclear boosters, who told me last month they want to see Ottawa approve construction of more of the Canucks’ homegrown reactor. In its latest earnings report, OPG said the BWRX-300, known as DNNP Unit 1, “is no longer expected to achieve the previously disclosed commercial operation date target of October 2030 or be completed with the previously disclosed estimated cost of $7.7 billion.”
Amid a flurry of funding cuts in the early days of the current Trump administration, the Department of Energy canceled an $87 million grant to the green cement startup Sublime Systems. In response, the company sued for damages. This week, the Somerville, Massachusetts-based firm filed legal documents accusing the agency of “refusing to comply with its basic discovery obligations and the schedule” for the case.
“The government has repeatedly delayed responding to Sublime’s discovery requests, and now the government is refusing to even meet and confer with Sublime until some indefinite date in the future,” read the joint status report filed with the U.S. Court of Federal Claims. “The upshot is that, as of today, the government has not produced a single document in response to Sublime’s requests for production (served nearly two months ago), it has provided no timeline by which productions will be completed, and it is refusing to search for core documents related to the May 2025 mass termination at the heart of this case.”

The Energy Department’s Office of Energy Dominance Financing, formerly the Loan Programs Office, closed a $480 million loan for a Texas-based company’s effort to modernize and boost production from 22 offshore oil and gas platforms in the Gulf of Mexico. Arena Energy, the Woodlands, Texas-based company behind the initiative dubbed Project Elkhorn, said that the initiative will add 38,600 barrels of oil per day and up to 77 million cubic feet of natural gas per day to U.S. energy output.
“The United States is the world’s largest producer and exporter of oil and natural gas, and thanks to President Trump, American energy production will continue to grow,” Secretary of Energy Chris Wright said in a statement. “By providing financing for projects like Project Elkhorn, the Energy Department is expanding domestic production and strengthening our energy security to power American prosperity for decades to come.”
QuantumScape emerged years ago as the frontrunner in the race to commercialize solid-state batteries that last longer, charge more quickly, and function better under harsh conditions than liquid-based lithium-ion packs. On Wednesday, the San Jose, California-based startup unveiled what it called in a press release its “next-generation open platform for all-solid-state batteries.” Dubbed Osprey, the cells “deliver the world’s first public data demonstrating a sulfide-based cathode cycling 1,000 times under just one atmosphere of pressure.” In other words: “an unmatched capability that is necessary for automotive solid-state batteries.”
“Osprey is a next-generation platform that is built on our same core technology, the ceramic separator and anode-free design,” Siva Sivaram, QuantumScape’s chief executive, told me in an email last night. “It will allow us to provide the unique benefits of our ceramic separator to developers of all-solid-state batteries using sulfide-based cathodes.” The company plans to start mass producing its cells in 2028, he said.
Bill Gates boasts that he has committed more of his fortune to fighting climate change than virtually any other rich man in the world. But a new investigation by ProPublica found that he’s ramped up his investments in a landfill company, Republic Services, that spews millions of tons of greenhouse gases into the atmosphere. “It seems very likely that Bill Gates has the power to influence Republic’s behavior to make it more climate-friendly, even if that costs the company profits,” Ann Lipton, a legal scholar who studies corporate governance at the University of Colorado, Boulder, told the outlet.
