From the Inflation Reduction Act to our summer inferno to an anti-car paradise and everything in between.
I may be the new kid on the block (ICYMI I joined in November as Heatmap’s deputy editor), but if anything, I think that makes me even more qualified to talk about the most popular stories from our nine-ish months in existence — after all, for most of that time I was reading them, not working on them.
The list spans stories from the day we launched in March all the way to our coverage of COP28, which concluded just a few weeks ago. There are stories on the quest to build out renewable energy infrastructure, how to use the Inflation Reduction Act to save on your home renovation projects, and living through our summer of heat, but also stories on surfing and subways and Tokyo.
As happens with any such list, a vivid picture of you — our much-valued readers — emerges from between the lines. Climate change isn’t just the biggest story of our time, it’s also the biggest story of our lives. The curiosity you have is personal — not just about how governments are trying to solve this crisis, but also about how you can play a role; not just about electrons and molecules, but also about places and people.
If we didn’t love you already, we certainly would after seeing this list. Thanks so much for reading. We’ll see you in 2024.
The IRA consists of dozens of subsidies to help individuals, households, and businesses adopt clean energy technologies. Many of these solutions will also help people save money on their energy bills, reduce pollution, and improve their resilience to disasters.
But understanding how much funding is available for what, and how to get it, can be pretty confusing. Many Americans are not even aware that these programs exist. If you haven’t heard much about how the IRA can help you decarbonize your life, this guide is for you. If you have heard about the available subsidies, but aren’t sure how much they are worth or where to begin, Emily will walk you through it. (And if you’re looking for information about the electric vehicle tax credit, my colleague at Heatmap Robinson Meyer has you covered with this buyer’s guide.)
The ill tidings started early on a Friday morning with SolarEdge, a company that primarily sells inverters, which convert the electricity produced by a solar panel into the kind that can be used in homes.
In an unexpected announcement, SolarEdge’s chief executive Zvi Lando said that, in the third quarter, the company had “experienced substantial unexpected cancellations and pushouts of existing backlog from our European distributors.” Many of its core financial metrics, including revenue and operating income, would fall below the low end of the range it had projected earlier, SolarEdge warned. The company also said it expected “significantly lower revenues in the fourth quarter.” (SolarEdge is based in Israel but the company said that the Hamas-Israel war was not related to their financial troubles.)
Investors promptly panicked, selling off the stock and sending it down 27% in trading by the afternoon. The worry is that the problems SolarEdge identified are not unique to the company itself or even the inverter business, but to the solar industry as a whole.
What keeps emergency management officials up at night? Terrorist attacks. The Big One. A direct hit from a Category 5 hurricane.
But when it comes to climate-related disasters, one fear often rises above the rest: a blackout during a heat wave. According to new research published this spring, a two-day citywide blackout in Phoenix during a heat wave could lead to half the population — some 789,600 people — requiring emergency medical attention in a metropolitan area with just 3,000 available beds. As many as 12,800 people could die, the equivalent of more than nine Hurricane Katrinas.
So if the power goes out during a heat wave, what do you do?
The region’s major utilities — Arizona Public Service, Tucson Electric Company, and the Salt River Project — have all said they’re confident that the lights, and especially the air conditioning, will stay on, even as both temperatures and electricity usage break records. This is in stark contrast to a nearby state, Texas, where record heat has sparked anxiety about reliability and voluntary calls for conserving energy use.
Whether Arizona can transition to a less carbon-intensive grid while maintaining its famed reliability is a test not just for its residents, but also for Arizona’s stubborn rejection of energy deregulation.
In the last few years, climate change has made its impact known in violent, eye-grabbing ways. Heat waves and drought slowly roll across the planet; hurricanes and floods and wildfires bring sudden devastation to communities that were once safe. But there are also slower, more insidious impacts that we can easily forget about in the wake of those disasters, including the most classic impact of them all: sea-level rise.
The East Coast is particularly vulnerable to rising seas, and in her new book Charleston: Race, Water, and the Coming Storm (Pegasus Books, April 4, 2023), Susan Crawford, a writer and professor at Harvard Law School, explores how the historic city, the largest in South Carolina, is preparing — or failing to prepare — for what’s to come. Flooding has become increasingly commonplace in Charleston, Crawford writes, and the city’s racial history has meant that low-income communities of color are bearing the worst of the impact, with little hope for relief.
“It’s Confederate Disneyland,” Crawford told Neel in an interview about the book, “and it’s about to be SeaWorld.”
On Methane Day at COP28 in Dubai, and there was a slew of new commitments to wrangle the highly potent, short-lived greenhouse gas. This is not the first time many of these groups have pledged to address methane, which leaks into the atmosphere from oil and gas infrastructure, coal mines, landfills, and farms. But taken together, today’s actions bring more ambition, transparency, and accountability to the task.
During a press briefing on Friday morning, U.S. Climate Envoy John Kerry told reporters that reducing methane emissions is the “easiest, quickest, cheapest, simplest” way to fight climate change. But for an issue that’s so easy to address, the scourge on methane has sucked up a lot of oxygen in the climate conversation over the past five years.
Neel has spent a lot of time thinking about how to cover heat waves. Each is unique — suffering of any kind is always unique, even if the broad strokes are not — yet the things one can say about them are, for the most part, largely the same. Records will break, power grids will strain, and people will be hurt: This is the reality of climate change.
So this year, we tried an experiment: We documented particularly notable heat waves around the world as they happened, but rather than devote separate stories to them, each heat wave got a short entry within this larger page. We called out especially vivid details or statistics and include links to local outlets that can provide more information to anyone looking for it. The goal here was to create a record of the very real impact of climate change today.
For cities that want to reduce the number of cars, bike lanes are a good place to start. They are cheap, usually city-level authorities can introduce them, and they do not require you to raise taxes on people who own cars. What if you want to do something more radical though? What would a city that genuinely wanted to get the car out of its citizens’ lives in a much bigger way do? A city that wanted to make it possible for most people to live decent lives and be able to get around without needing a car, even without needing to get on a bicycle?
There is only one city on Earth Daniel has ever visited that has truly managed this. But it happens to be the biggest city on the planet: Tokyo, the capital of Japan.
Dr. Cliff Kapono sometimes still surfs the way his Indigenous Hawaiian ancestors did 1,000 years ago, on a traditional wooden board and all. But the professional surfer and molecular biologist fears his descendants might not have the same privilege. The reason is the looming scarcity of surfable waves.
While climate change could be a boon for big-wave surfers, as some have highlighted, the beloved recreational side of the sport is endangered by the shifting climate. Dramatic changes are already locked in, with rising waters swallowing surf breaks and wary communities erecting sea walls that alter the shape of the coastline. But this tension — between the masses losing access to cherished resources and the few who benefit even as they lament — is not exclusive to surfers; it’s one that bedevils almost anything related to climate adaptation.
As a metropolis that runs on the fumes of pure defiance and chaos magic even during the best of times, New York was understandably struggling to stay afloat after a month’s worth of rain fell within a few hours one Friday morning in Septemnber. Subway staircases transformed into white-water obstacles more befitting of Action Park than America’s most populous city, while trash cans embarked from their curbside moorings, destined for unknown shores. Cars — half-submerged and looking curiously hippopotamine — nosed their way through the city’s new waterways. The Central Park sea lion exhibit overflowed with, well, sea lions. A manhole outside Joe’s Pizza in the East Village caught fire, the result of short-circuiting electrical cables. In Brooklyn, inexplicably, a whirlpool appeared.

On power plant emissions, Fervo, and a UK nuclear plant
Current conditions: A week into Atlantic hurricane season, development in the basin looks “unfavorable through June” • Canadian wildfires have already burned more land than the annual average, at over 3.1 million hectares so far• Rescue efforts resumed Wednesday in the search for a school bus swept away by flash floods in the Eastern Cape province of South Africa.
EPA
The Environmental Protection Agency plans to announce on Wednesday the rollback of two major Biden-era power plant regulations, administration insiders told Bloomberg and Politico. The EPA will reportedly argue that the prior administration’s rules curbing carbon dioxide emissions at coal and gas plants were misplaced because the emissions “do not contribute significantly to dangerous pollution,” per The Guardian, despite research showing that the U.S. power sector has contributed 5% of all planet-warming pollution since 1990. The government will also reportedly argue that the carbon capture technology proposed by the prior administration to curb CO2 emissions at power plants is unproven and costly.
Similarly, the administration plans to soften limits on mercury emissions, which are released by burning coal, arguing that the Biden administration “improperly targeted coal-fire power plants” when it strengthened existing regulations in 2024. Per a document reviewed by The New York Times, the EPA’s proposal will “loosen emissions limits for toxic substances such as lead, nickel, and arsenic by 67%,” and for mercury at some coal power plants by as much as 70%. “Reversing these protections will take lives, drive up costs, and worsen the climate crisis,” Climate Action Campaign Director Margie Alt said in a statement. “Instead of protecting American families, [President] Trump and [EPA Administrator Lee] Zeldin are turning their backs on science and the public to side with big polluters.”
Fervo Energy announced Wednesday morning that it has secured $206 million in financing for its 400-megawatt Cape Station geothermal project in southwest Utah. The bulk of the new funding, $100 million, comes from the Breakthrough Energy Catalyst program.
Fervo’s announcement follows on the heels of the company’s Tuesday announcement that it had drilled its hottest and deepest well yet — at 15,000 feet and 500 degrees Fahrenheit — in just 16 days. As my colleague Katie Brigham reports, Fervo’s progress represents “an all too rare phenomenon: A first-of-a-kind clean energy project that has remained on track to hit its deadlines while securing the trust of institutional investors, who are often wary of betting on novel infrastructure projects.” Read her full report on the clean energy startup’s news here.
The United Kingdom said Tuesday that it will move forward with plans to construct a $19 billion nuclear power station in southwest England. Sizewell C, planned for coastal Suffolk, is expected to create 10,000 jobs and power 6 million homes, The New York Times reports. Sizewell would be only the second nuclear power plant to be built in the UK in over two decades; the country generates approximately 14% of its total electricity supply through nuclear energy. Critics, however, have pointed unfavorably to the other nuclear plant under construction in the UK, Hinkley Point C, which has experienced multiple delays and escalating costs throughout its development. “For those who have followed Sizewell’s progress over the years, there was a glaring omission in the announcement,” one columnist wrote for The Guardian. “What will consumers pay for Sizewell’s electricity? Will it still be substantially cheaper in real terms than the juice that will be generated at Hinkley Point C in Somerset?” The UK additionally announced this week that it has chosen Rolls-Royce as the “preferred bidder” to build the country’s first three small modular nuclear reactors.
The European Union on Tuesday proposed a ban on transactions with Nord Stream 1 and 2 as part of a new package of sanctions aimed at Russia, Bloomberg reports. “We want peace for Ukraine,” the president of the European Commission, Ursula von der Leyen, said at a news conference in Brussels. “Therefore, we are ramping up pressure on Russia, because strength is the only language that Russia will understand.” The package would also lower the price cap on Russian oil to $45 a barrel, down from $60 a barrel, von der Leyen said, as well as crack down on Moscow’s “shadow fleet” of vessels used to transport sanctioned products like crude oil. The EU’s 27 member states need to unanimously agree to the package for it to be adopted; their next meeting is on June 23.
The world’s oceans hit their second-highest temperature ever in May, according to the European Union’s Earth observation program Copernicus. The average sea surface temperature for the month was 20.79 degrees Celsius, just 0.14 degrees below May 2024’s record. Last year’s marine heat had been partly driven by El Niño in the Pacific, so the fact that the oceans remain warm in 2025 is alarming, Copernicus senior scientist Julien Nicolas told the Financial Times. “As sea surface temperatures rise, the ocean’s capacity to absorb carbon diminishes, potentially accelerating the build-up of greenhouse gases in the atmosphere and intensifying future climate warming,” he said. In some areas around the UK and Ireland, the sea surface temperature is as high as 4 degrees Celsius above average.

The Pacific Island nation of Tonga is poised to become the first country to recognize whales as legal persons — including by appointing them (human) representatives in court. “The time has come to recognize whales not merely as resources but as sentient beings with inherent rights,” Tongan Princess Angelika Lātūfuipeka Tukuʻaho said in comments delivered ahead of the U.N. Ocean Conference in Nice, France.
Microsoft, Amazon, Google, and the rest only have so much political capital to spend.
When Donald Trump first became a serious Presidential candidate in 2015, many big tech leaders sounded the alarm. When the U.S. threatened to exit the Paris Agreement for the first time, companies including Google, Microsoft, Apple, and Facebook (now Meta) took out full page ads in The New York Times and The Wall Street Journal urging Trump to stay in. He didn’t — and Elon Musk, in particular, was incensed.
But by the time specific climate legislation — namely the Inflation Reduction Act — was up for debate in 2022, these companies had largely clammed up. When Trump exited Paris once more, the response was markedly muted.
Now that the IRA’s tax credits face clear and present threats, this same story is playing out again. As the Senate makes its changes to the House’s proposed budget bill, tech giants such as Microsoft, Google, Meta, and Amazon are keeping quiet, at least publicly, about their lobbying efforts. Most did not respond to my request for an interview or a statement clarifying their position, except to say they had “nothing to share on this topic,” as Microsoft did.
That’s not to say they have no opinion about the fate of clean energy tax credits. Microsoft, Google, Meta, and Amazon have all voluntarily set ambitious net-zero emissions targets that they’re struggling to meet, largely due to booming data center electricity demand. They’re some of the biggest buyers of solar and wind energy, and are investing heavily in nuclear and geothermal. (On Wednesday morning, Pennsylvania’s Talen Energy announced an expanded power purchase agreement with Amazon, for nearly 2 gigawatts of power through 2042.) All of these energy sources are a whole lot more accessible with tax credits than without.
There’s little doubt the tech companies would prefer an abundant supply of cheap, clean energy. Exactly how much they’re willing to fight for it is the real question.
The answer may come down to priorities. “It’s hard to overstate how much this race for AI has just completely changed the business models and the way that these big tech companies are thinking about investment,” Jeff Navin, co-founder of the climate-focused government affairs firm Boundary Stone Partners, told me. “While they’re obviously going to be impacted by the price of energy, I think they’re even more interested and concerned about how quickly they can get energy built so that they can build these data centers.”
The tech industry has shown much more reluctance to stand up to Trump, period, this time around. As the president has moved from a political outsider to the central figure in the Republican party, hyperscalers have increasingly curried his favor as they advocate against actions that could pose an existential risk to their business — think tighter regulations on the tech sector or AI, or tariffs on key supplies made in Asia.
As Navin put it to me, “When you have a president who has very strong opinions on wind turbines and randomly throws companies’ names in tweets in the middle of the night, do you really want to stick your neck out and take on something that the president views as unpopular if you’ve got other business in front of him that could be more impactful for your bottom line?”
It is undeniably true that the AI-driven data center boom is pushing these companies to look for new sources of clean power. Last week Meta signed a major nuclear deal with Constellation Energy. Microsoft is also partnering with Constellation to reopen Three Mile Island, while Google and Amazon have both announced investments in companies developing small modular reactors. Meta, Google, and Microsoft are also investing in next-generation geothermal energy startups.
But while the companies are eager to tout these partnerships, Navin suspects most of their energy lobbying is now being directed towards efforts such as permitting reform and building out transmission infrastructure. Publicly available lobbying records confirm that these are indeed focus areas, as they’re critical to bringing data centers online quickly, regardless of how they’re powered and whether that power is subsidized. “They’re not going to stop construction on an energy project that has access to electricity just because that electricity is marginally more expensive,” Navin told me. “There’s just too much at stake.”
Tech companies have lobbied on numerous budget, tax, sustainability, and clean energy issues thus far this year. Amazon’s lobbying report is the only one to specifically call out efforts on “renewable energy tax credits,” while Meta cites “renewable energy policy” and Microsoft name-drops the IRA. But there’s no hard and fast standard for how companies describe the issues they’re lobbying on or what they’re looking to achieve. And perhaps most importantly, the reports don’t disclose how much money they allot to each issue, which would illuminate their priorities.
Lobbying can also happen indirectly, via industry groups such as the Clean Energy Buyers Association and the Data Center Coalition. Both have been vocal advocates for preserving the tax credits. The Wall Street Journal recently detailed a lobbying push by the latter — which counts Microsoft, Amazon, Meta, and Google among its most prominent members — that involved meetings with about 30 Republican senators and a letter to Senate Majority Leader John Thune.
DCC didn’t respond to my request for an interview. But CEBA CEO Rich Powell told me, “If we take away these incentives right now, just as we’re getting the rust off the gears and getting back into growth mode for the electricity economy, we’re really concerned about price spikes.”
The leader of another industry group, Advanced Energy United, shared Powell’s concern that passing the bill would mean higher electricity prices. Taking away clean energy incentives would ”fundamentally undercut the financing structure for — let’s be frank — the vast majority of projects in the interconnection queue today,” Harry Godfrey, the managing director of AEU, told me.
Being part of an industry association is by no means a guarantee of political alignment on every issue. Microsoft, Google, Meta, and Amazon are also members of the U.S. Chamber of Commerce — by far the largest lobbying group in the U.S. — which has a long history of opposing climate action and the IRA itself. Apple even left the Chamber in 2009 due to its climate policy stances.
But Powell and Godfrey implied that the tech giants' views are — or at least ought to be — in alignment with theirs. “Many of our members are lobbying independently. Many of them are lobbying alongside us. And then many of them are supporting CEBA to go and lobby on this,” Powell told me, though he wouldn’t reveal what actions any specific hyperscalers were taking.
Godfrey said that AEU’s positions are “certainly reflective of what large energy consumers, notably tech companies, have been working to pursue across a variety of technologies and with applicability to a couple of different types of credits.”
And yet hyperscalers may have already spent a good deal of their political capital fighting for a niche provision in the House’s version of the budget bill, which bans state-level AI regulation for a decade. That would make the AI boom infinitely easier for tech companies, who don’t want to deal with a patchwork of varying regulations, or really most regulations at all.
On top of everything else, big tech in particular is dealing with government-led anti-trust lawsuits, both at home and abroad. Google recently lost two major cases to the Department of Justice, related to its search and advertising business. A final decision is pending regarding the Federal Trade Commission’s antitrust lawsuit against Meta, regarding the company’s acquisition of Instagram and WhatsApp. Not to be outdone, Amazon will also be fighting an antitrust case brought by the FTC next year.
As these companies work to convince the public, politicians, and the courts that they’re not monopolistic rule-breakers, and that AI is a benevolent technology that the U.S. must develop before China, they certainly seem to be relinquishing the clean energy mantle they once sought to carry, at least rhetorically. We’ll know more once all these data centers come online. But if the present is any indication, speed, not green electrons, is the North Star.
Editor’s note: This story has been updated to reflect Amazon’s power purchase agreement with Talen Energy.
The new funding comes as tax credits for geothermal hang in the balance.
The good news is pouring in for the next-generation geothermal developer Fervo Energy. On Tuesday the company reported that it was able to drill its deepest and hottest geothermal well to date in a mere 16 days. Now on Wednesday, the company is announcing an additional $206 million in financing for its Cape Station project in Utah.
With this latest tranche of funding, the firm’s 500-megawatt development in rural Beaver County is on track to deliver 24/7 clean power to the grid beginning in 2026, reaching full operation in 2028. The development is shaping up to be an all-too-rare phenomenon: A first-of-a-kind clean energy project that has remained on track to hit its deadlines while securing the trust of institutional investors, who are often wary of betting on novel infrastructure projects.
The bulk of this latest financing comes from the Bill Gates-backed Breakthrough Energy Catalyst program, which provided $100 million in project-level equity funding. The energy and commodity trading company Mercuria provided $60 million in corporate loans, increasing its existing fixed-term loan from $40 million to $100 million. An additional $45.6 million in short-term debt financing came from XRL-ALC, an affiliate of X-Caliber Rural Capital, which provides loans to infrastructure projects in rural areas. That comes on top of a previous $100 million loan from the firm.
The plan is for Cape Station to deliver 100 megawatts of grid power in 2026, with the additional 400 megawatts by 2028. The facility has the necessary permitting to expand production to two gigawatts — twice the size of a standard nuclear reactor. And on Monday, the company announced that an independent report from the consulting firm DeGolyer & MacNaughton confirms that the project could expand further still — eventually supporting over 5 gigawatts of clean power at depths of up to 13,000 feet. The company’s latest drilling results, which reached 15,765 feet at 520 degrees Fahrenheit, could push the project’s potential power output even higher.
Traditional geothermal wells normally max out at around 10,000 feet, and must be built in locations where a lucky confluence of geological features come together: high temperatures, porous rock, and naturally occurring water or steam. But because Fervo can drill thousands of feet deeper, it’s able to access hot rocks in locations that weren’t previously suitable for geothermal development, pumping high-pressure water down into the wells to fracture rocks and thus create its own geothermal reservoirs.
The primary customer for Fervo’s Cape Station project is Southern California Edison, which signed a 320-megawatt power purchase agreement with the company last year, advertised as the largest geothermal PPA ever. Shell was also announced as a customer this year. Fervo is already providing 3.5 megawatts of power to Google via a pilot project in Nevada, which it’s seeking to expand, entering into a 115 megawatt PPA with NV Energy and the tech giant to further build out production at this location.
Fervo’s latest funding comes on top of last February’s $244 million Series D round led by Devon Energy, as well as an additional $255 million in corporate equity and debt financing that it announced last December. On top of investments from well known climate tech venture firms such as Breakthrough Energy Ventures and Galvanize Climate Solutions, the company has secured institutional investment from Liberty Mutual as well as public pension funds such as the California State Teachers’ Retirement System and the Canada Pension Plan Investment Board.
Fervo, like all clean energy startups, also stands to benefit greatly from the Inflation Reduction Act’s clean energy tax credits, which are now in jeopardy as President Trump’s One Big, Beautiful Bill works its way through the Senate. While Secretary of Energy Chris Wright has traditionally been a booster of geothermal energy and is advocating to keep tax incentives for the technology in place through 2031, the bill as it stands would essentially erase incentives for all geothermal projects that start construction more than 60 days after the bill’s passage.
Fervo broke ground on Cape Station in 2023, so that project will make the cut. For future Fervo developments, it’s much less clear. But for now, the company seems to be flush with cash and potential in a climate tech world awash in ill omens.
