A firestorm over stoves couldn't stop these states from reining in gas.

One of the biggest climate stories of the year — the first, and perhaps only, to go viral — didn’t so much draw attention to the warming planet as it did to the dangers of using fossil fuels.
During the second week of January, Bloomberg reported that a federal safety agency would “consider a ban on gas stoves amid health fears.” Though the headline was somewhat misleading — the commission was investigating the risks of cooking with gas, but a ban was not immediately forthcoming — the article invited swift backlash.
The next day, the Wall Street Journal editorial board published an op-ed warning readers that “Biden is coming for your gas stove.” Conservative politicians expressed their undying loyalty to the appliance. “If the maniacs in the White House come for my stove, they can pry it from my cold dead hands. COME AND TAKE IT!!,” Ronny Jackson, a Republican congressman from Texas, posted on Twitter. Governor Ron DeSantis of Florida designed aprons bearing an illustration of a gas stove that said “Don’t Tread on Florida.” Democratic Senator Joe Manchin of West Virginia also piled on, tweeting, “I can tell you the last thing that would ever leave my house is the gas stove that we cook on.” House Republicans eventually passed a bill called the Gas Stove Protection and Freedom Act.
Meanwhile, everyday Americans were trying to make sense of the news that their gas stoves could be harming them. Every major media outlet ran stories on the risks of cooking with gas and how to minimize them. “How bad is it actually?,” friends started asking me over drinks.
It’s not good. Burning natural gas releases nitrogen dioxide, a pollutant that contributes to respiratory illnesses like asthma. Concentrations from cooking can often exceed government standards for outdoor air quality. Proper ventilation with a range hood can reduce your exposure. But it won’t do anything about the effects gas has on the climate.
About 13% of U.S. emissions come from the fuels burned in buildings. Stoves may be a small part of that, but officials in some of the most climate-forward cities and states have been grappling with reducing the use of all fossil fuel-burning appliances in buildings for a number of years now. In February, the Building Decarbonization Coalition reported that 98 municipalities and four states — California, Washington, Maryland, and Colorado — had adopted policies promoting a switch to electric appliances. When the gas stove hysteria erupted, one in five Americans was already living under laws that encouraged or required landlords and developers to eschew gas.
A lot has happened in the months since, and not every state is swimming in the same direction on the issue. But in 2023, policymakers took big leaps toward a future without gas in buildings in three key ways:
There’s no blueprint for how to decommission thousands of miles of gas pipelines and retrofit millions of homes with electric appliances in a systematic, let alone equitable way. As a start, policymakers have generally followed the Law of Holes, as in, the first step is to stop digging — or in this case, stop growing demand for gas.
In 2019, the city of Berkeley, California, led the way, passing the first ordinance in the country to prohibit gas hookups in new buildings, and dozens of other cities followed. This year, New York became the first state to enact such a policy. The law requires all new buildings that are smaller than seven stories to be fully electric beginning in 2026, and applies to taller buildings in 2029.
“I think it’s huge that a state is doing it, not only because New York is a big-impact state,” Sarah Fox, an associate law professor at Northern Illinois University School of Law, told CNN at the time. It’s no longer “fringe cities passing these policies,” she said. “This is becoming a mainstream policy that a state like New York is taking on.”
However, this year also saw a continuation of Republican-led states taking the opposite tack. Montana, North Dakota, South Dakota, and Idaho joined a list of 24 states that have passed laws prohibiting municipalities from setting these kinds of restrictions on gas in buildings. By my estimation, using 2022 population data from the U.S. Census Bureau, that means two in five Americans live in states with such preemption laws.
Berkeley’s gas ban was also struck down by a federal appeals court, and the city is now fighting for a rehearing. That decision led to some uncertainty, but no loss of momentum. In Washington, where regulators created a de facto ban on gas in new construction through the building code last year, officials recently amended the code to safeguard it against legal challenges.
Utilities typically spend hundreds of millions of dollars each year maintaining, replacing, and building new pipes — funds they expect to recover from ratepayers over the course of decades.
This year, in a few states with strong emission reduction laws that imply heating will have to be electrified in the next few decades, regulators started to scrutinize these investments more. In Illinois, for example, the Commerce Commission ordered People’s Gas, which serves the Chicago area, to pause its pipe replacement program, rejecting the company’s request to hike rates to fund it.
“This program was deeply flawed,” Abe Scarr, state director of the Public Interest Research Group in Illinois, told me. It was supposed to address the real problem of risky iron pipes, but it had been mismanaged and over-budget for years, he said. At the current rate, the company won’t be done until 2049, “right around the time that a lot of us think we should be stopping to use the gas system.”
The commission ordered an investigation into the program. It also initiated a new “Future of Gas” proceeding for all utilities in the state to determine how to align the sector with Illinois’ clean energy goals. “As the State embarks on a journey toward a 100 percent clean energy economy, the gas system’s operations will not continue to exist in its current form,” said Illinois Commerce Commission Chairman Doug Scott in a press release.
Meanwhile, regulators in Massachusetts were wrapping up their own “Future of Gas” proceeding that had kicked off in 2020. In early December, the state’s Department of Public Utilities issued a final order declaring, among many other things, that it will no longer allow companies to recover costs for gas infrastructure without showing that alternatives, like helping customers electrify, were considered. Regulators also rejected the utilities’ preferred path to reducing emissions — switching to lower-carbon fuels like renewable natural gas and hydrogen — as not yet proven. Unless and until the evidence changes, any money the companies spend investigating these solutions will have to be covered by shareholders, not ratepayers.
Also this year, Massachusetts began testing one potentially more systematic pathway to transition off gas. Eversource, a utility there, broke ground on a first-of-its-kind project to switch an entire neighborhood to “networked geothermal,” a form of electric heating that draws on the steady temperature of the ground beneath the earth’s surface to heat and cool buildings.
In many states, it’s standard practice for utilities to bake the cost of political activities like lobbying, advertising, and trade association memberships into customers’ gas and electric rates. These activities often amount to efforts to slow down the clean energy transition — for example, an investigation published this year found that the American Gas Association has fought to stifle warnings about the risks of gas stoves for decades.
“[Utilities] are conscripting their customers into an unknowing army of millions of small-dollar donors to prolong the era of dirty energy,” David Pomerantz, executive director of the nonprofit Energy and Policy Institute, wrote in The New York Times earlier this year.
But now Maine, Colorado, and Connecticut, have all outlawed the practice; if utilities in those states want to spend money on lobbying or trade groups, they’ll have to pay for it out of their own profits. Massachusetts regulators took a similar step, banning gas companies from charging customers for any marketing related to the promotion of natural gas.
I asked Mike Henchen, a principal at the clean energy think tank RMI who follows gas utility regulation around the country, what the next wave of action on the issue might look like.
He said he expects progress to continue next year, with states rolling out rebates for heat pumps with money from the Inflation Reduction Act. Some, like New Jersey and Maryland may follow the playbooks written by first movers like New York and Massachusetts, and those leading states could continue to break new ground. One of the next fronts, he said, is removing the gas industry’s “obligation to serve,” a rule written into most state laws that gives customers the right to demand gas service. That means that even if there’s a strong economic argument to electrify a city block rather than replace a risky pipeline, one resident’s refusal could sink the whole project.
On the bright side, some utilities are starting to talk more openly about needing to reduce the amount of natural gas they sell to customers, Henchen told me. But midway through sharing this thought, he stopped to laugh. “I laugh, because it seems like it should be more obvious that that is the case.”

Welcoming the world’s first clean energy trillionaire.
SpaceX is now a public company. The rocket and satellite maker’s shares began trading this morning, surging 19% from their initial price of $135 to more than $160 at the market close. With the sale, Elon Musk became the world’s first trillionaire; his wealth has roughly tripled since President Donald Trump won re-election in 2024.
I’ll let other observers judge the IPO’s success, the firm’s long-term prospects, and the meaning of a world where we now have trillionaires. So I will make a few other points:
I remain agog at Musk’s ability to raise enormous amounts of cash from public equity markets to do hardware and manufacturing development. To some degree, the idea of a venture-backed firm doing hardware engineering — or what some now call “deep tech” — is Musk’s most impressive creation. The SpaceX IPO raised $75 billion today. That money will now go in part to scaling and commercializing rockets, factory equipment, and allegedly, at some point in the future, orbiting data centers.
Let’s not forget how crucial the U.S. government is to Musk’s story. In the world of climate, energy and manufacturing, we wail about financing’s “missing middle,” the elusive type of investment that can help scale and deploy early-stage technologies by bridging the gap between expensive venture capital and cheap bank lending. But this is at least partially a solved problem. SpaceX and Tesla survived the valley of death with government help: The Energy Department’s Loan Programs Office (which the Trump administration has dubbed the Office of Energy Dominance Financing) extended a $465 million loan to Tesla to build its Fremont, California, factory in 2010; NASA’s 2008 commercial resupply contract gave SpaceX guaranteed offtake for its Falcon rocket. Neither firm would likely have survived without those key injections of financial certainty.
To some degree, Musk has already made his mark on the American economy by creating a new culture of manufacturing engineering. I cannot recommend enough my colleagues Matthew Zeitlin and Emily Pontecorvo’s report on the new cadre of climate tech founders who came up at SpaceX and Tesla. As it happens, I spent Wednesday touring a clean energy factory founded by a Tesla alumnus, and I was struck by how many signs of Musk’s bottlenecks-focused management approach were visible, even at a company seemingly run more humanely than Musk’s famously “hardcore” firms.

To that point, Emily and Matt asked a number of clean tech executives who worked for SpaceX or Tesla what they learned from the experience. Their responses are fascinating; you can read them in full here. These comments from Justin Lopas, the COO of Base Power, stuck out — he was asked the “one thing” he learned from working for Musk:
You can get way more done in a day and can move way faster than you think. This does not mean necessarily more hours (although solving any hard problem requires that too), but instead being thoughtful about sequencing work, not accepting delays from suppliers or external counterparties without solid rationale, parallel pathing, accelerating critical learnings to early in the project, etc
To step back, one irony of Elon Musk’s situation — at least to me — is that relatively few American politicians are eager to talk about what has actually driven his wealth. I’m not just talking about his firms’ reliance on public financing, although that counts too. I mean Tesla itself. Although Musk now describes that business as a “robotics company,” it is and remains an electric vehicle and battery manufacturer. (It recently began high-volume production of the Tesla Semi, a potentially game-changing long-haul electric truck.) After today, Musk’s Tesla stake makes up less than half of his wealth, but, still, he would not be a trillionaire without EVs, solar panels, and batteries.
But that is not a particularly convenient fact. That Musk is a clean energy trillionaire remains unpalatable to Republicans, who would prefer to cast EVs as an inferior substitute made to satisfy government mandates. And Musk’s antisemitism, far-right politics, and gleeful destruction of the U.S. Agency for International Development — not to mention Tesla’s violation of labor law — have obviously destroyed his reputation among Democrats.
Yet his elevation to a 13-digit net worth nonetheless marks a new era in American capitalism. The richest Americans in history have almost always been oilmen: John D. Rockefeller became the country’s first billionaire by creating the Standard Oil trust; when he died in 1937, his net worth of $1.4 billion represented 1% to 2% of the country’s gross domestic product. In the 1960s, J. Paul Getty became the country’s richest person by negotiating Saudi and Kuwaiti oil concessions. Yet Musk became a billionaire not by harnessing commodities, but through his mastery of software, hardware, and clean energy.
Musk’s fortune now exceeds 3% of U.S. GDP. He is the richest American in history, judged as a share of national production. And it was electricity, lithium, and modern factory production — and, if you wish, the kerosene and methane that fuel SpaceX’s rockets — that got him there. As the science fiction writer William Gibson almost said, the future is already here; it’s just not evenly distributed in your retirement portfolio yet.
Many thanks for reading, and have a wonderful weekend.
Plus SAF, another SPAC, and more of the week’s biggest money moves.
With SpaceX’s historic IPO dominating headlines this week, Heatmap turned its attention to the impact Elon Musk’s protégés have had on the climate tech landscape. Right after we published the story, an underwater geothermal startup founded and staffed by SpaceX alumni announced a sizable Series A, with its founder telling TechCrunch that his “experience at a very hardcore company like SpaceX” helped shape his approach to this new endeavor.
In other news, one of the biggest players in the sustainable aviation space, Twelve, opened its first commercial fuels plant and is preparing to begin supplying low-carbon jet fuel to Alaska Airlines later this month. Meanwhile, the battery sector saw two SPAC announcements: In a bid for survival, Factorial Energy officially went public this week through a SPAC merger, while ZincFive announced plans to do the same later this year. And finally there was some positive news for Germany’s heat pump market, as the startup Galvany raised fresh funding to simplify the end-to-end process of buying, installing, and operating a heat pump.
Drawing from an increasingly familiar playbook for Musk alumni, Endurance Energy founder and former SpaceX engineer Andrew Redd applied the lessons he learned from the rocket company’s notoriously “hardcore” culture and rapid pace of development to something completely different. Now that he’s pivoted away from rocket tech, Redd wants to harness geothermal energy from underwater volcanic activity, and his startup just raised a $54 million Series A to make it happen While a growing crop of geothermal startups including Fervo and Zanskar are focused on tapping into the heat beneath our feet, no other company in the sector has sought to develop the resource beneath the ocean floor.
There are good reasons for that, of course. Offshore infrastructure is notoriously difficult and expensive to build, maintain, and repair, and saltwater is corrosive. But if Endurance can crack the code, Redd told TechCrunch he thinks the company could unlock about 6 terawatts of geothermal energy in the coming decade.
Investors seem to be convinced: Peter Thiel’s Founders Fund led the startup’s latest funding roundSeries A, its second capital raise since launching less than two years ago. Other backers include First Round Capital, Felicis Ventures, and Voyager Ventures. EnduranceThe startup is initially targeting remote islands, where electricity costs are often far higher than on the mainland. It’s already launched an initial pilot off the coast of Tonga, which still gets about 80% of its electricity from imported diesel.
Twelve, one of the best capitalized sustainable aviation fuel startups, opened its first e-fuel facility in Washington State this week. The demo plant has officially started production, and the company’s strategic partner and investor, Alaska Airlines, expects to begin using it on commercial flights as soon as this month. The plant’s launch comes roughly two years later than originally planned, a delay that’s hardly unusual for first-of-a-kind industrial projects like this. Last September, Twelve raised $645 million to complete buildout of the facility, as well as to jumpstart development of future plants, which it says will be orders of magnitude larger.
The company’s process begins with renewable-powered electrolysis. Using a proprietary catalyst, Twelve’s electrolyzer splits apart CO2 captured from a nearby ethanol plant at a lower temperature than conventional approaches, making it better suited to running on renewable energy. The company combines the resulting carbon monoxide with hydrogen to create a syngas, which gets refined into sustainable jet fuel. Airlines can blend the resulting product with conventional jet fuel (the Federal Aviation Administration allows a maximum 50% blend) to create a drop-in replacement that requires no engine modifications.
To cover the cost premium of SAF, Twelve and Alaska partnered with Microsoft. The tech giant is buying SAF certificates — essentially carbon credits — from the project to help offset Scope 3 emissions associated with employee travel. “We are seeing strong demand from the corporate offtake side, not only for employee travel, but also for freight and logistics,” Twelve’s CEO, Nicholas Flanders, told me. “Everything from pharmaceuticals to data centers use a lot of air travel.” There are also some policy tailwinds — the European Union now has a sustainable fuels mandate that requires the use of synthetic e-fuels like Twelve’s beginning in 2030.
The plant also comes online at a moment of heightened volatility in the jet fuel market. As my colleague Alexander C. Kaufman noted in Wednesday’s morning newsletter, the closure of the Strait of Hormuz has led to soaring fuel prices, prompting domestic refiners to ramp production to record highs. By contrast, Flanders argues that SAF offers customers greater price certainty via long-term offtake agreements. “You can fix the cost of our key inputs like electricity and CO2 and so that actually makes it a more attractive project from a project financing perspective,” he explained.
SPACs are back. But this week, it’s not just another pre-revenue nuclear company that’s looking to get to market as quickly as possible. Solid-state battery startup Factorial Energy, which has yet to develop a commercial product, has merged with the blank check company Cartesian Growth Corporation III, netting it $100 billion at a $1.3 billion valuation.
The company was upfront about needing the SPAC to stay afloat after racking up losses since its founding in 2013. Factorial’s SEC filing states that prior to this new capital, “its liquidity wasn’t sufficient to fund twelve months of operations.” Yet it does have real traction in the industry — Mercedes-Benz, Stellantis, Hyundai, and Kia have all made strategic investments, looking to use Factorial’s tech in their electric vehicles to achieve higher energy density, longer range, and faster charging.
Solid state batteries typically use a solid electrolyte in place of the flammable liquid electrolytes found in conventional lithium-ion cells, but Factorial is starting with more of a hybrid approach. Its initial design relies on a “quasi-solid” gel-like electrolyte, which allows it to use an energy dense lithium metal anode while preventing the needle-like dendrite growth that predisposes solid-state batteries to short circuit. Factorial is manufacturing these cells at a pilot plant in Massachusetts, while working on a prototype with a fully solid electrolyte that could offer even greater performance gains.
Factorial isn’t the only battery company with SPAC news this week. ZincFive, a nickel-zinc battery producer, also announced plans to go public via SPAC in a deal expected to close in the second half of this year. Unlike Factorial, however, ZincFive is already making money, selling its batteries to hyperscalers and other data center operators as a backup power solution to bridge the gap in between when the power goes out and when the backup generator turns on. As the company’s CEO Tod Higinbotham told Bloomberg, “We have the backlog. We have the capacity. We have the demand. We really need capital.”
Navigating the maze of consumer clean energy incentives and coordinating home energy upgrades is hardly a U.S.-specific challenge. Just a few years ago, heat pump sales in Germany were falling precipitously despite generous subsidies and proven tech. One startup, Galvany, theorized the problem wasn’t the heat pumps themselves, but rather the unnecessary complexity of the surrounding ecosystem. Now it’s raised roughly $11.5 million to help streamline the process of getting heat pumps into consumers’ homes and apartments.
“In Germany, heat pumps do not fail because of the technology, but because of the gap between subsidy bureaucracy, installation capacity, and economic viability for the end customer,” the company’s CEO, Raik Belka, said in a press release. This is exactly the gap we are closing.” The approach is already paying off — Galvany has installed more than 2,500 heat pumps to date and became profitable last year after increasing its revenue sevenfold.
The startup produces its heat pump in partnership with Panasonic, but its real innovation lies in the way it streamlines sales, procurement, installation, and ongoing heat pump operations into a single platform. Potential customers enter their building data online and, after a feasibility check, get a quick quote that factors in subsidies. They can then purchase a standardized kit that’s simple for installers to assemble. Once operational, the heat pump’s energy management system, which launches this summer, will automatically adjust heating loads based on the cost of electricity, saving customers money without them having to actively manage the system.
The administration filed to dismiss an appeal of a December ruling that overturned its wind permitting freeze.
Trump’s Department of Justice is giving up on defending the president’s wind permitting moratorium.
The DOJ filed a motion on Wednesday to dismiss its appeal of a federal court’s December decision vacating the order to halt wind energy approvals. The plaintiffs in the case — New York and 16 other states, as well as the Alliance for Clean Energy New York, a trade group — did not oppose the motion. The case will not be officially dismissed, however, until the First Circuit Court of Appeals approves the request, which typically happens quickly when both parties support the dismissal.
The case stems from an executive order President Trump issued on the first day of his current term temporarily withdrawing all areas of the outer continental shelf from offshore wind leasing and pausing all federal authorizations for onshore and offshore wind projects while the administration conducted a review of leasing and permitting practices.
States took the administration to court last May, arguing that the order was arbitrary and capricious and violated the Administrative Procedures Act. They claimed it harmed their ability to source reliable and affordable energy and threatened billions of dollars in investment in supply chains, workforce development, and wind industry-related infrastructure.
On December 8, Judge Patti B. Saris of the U.S. District Court for the District of Massachusetts ruled in the states’ favor and vacated the wind order. More specifically, the judge vacated the portion of the order directing agencies to pause permits and other authorizations. The withdrawal of areas eligible for new leases remains in effect.
What it means is that federal agencies will now have to proceed with permitting wind projects using the existing statutory and regulatory framework, Kit Kennedy, the managing director for power, climate, and energy at the Natural Resources Defense Council, told me in an email. “The door to federal permitting is now unlocked again and each developer will be able to make the case for permitting their individual project based on the facts and the law,” she said.
The Trump administration appealed the ruling to the First Circuit in February, but never submitted an opening brief. The initial deadline was May 11, but on May 4, the DOJ requested additional time to file the brief. The judge gave the defendants until June 10. On that date, the defendants filed the motion to dismiss.
This is a developing story and we’ll update it as we learn more about the administration’s actions and their effects.
Editor’s note: This story has been updated to reflect that the freeze and ruling apply to onshore as well as offshore wind. It also adds a quote from Kit Kennedy.
