See also: federal policy, batteries, and electricity demand.

The clean energy industry is beginning to report to investors and the public on its first brush with Donald Trump’s trade policy. While earnings season has only just begun, already some broad themes are emerging across the sector: Tariffs hurt. Batteries are getting more expensive. And there’s big demand for power, especially natural gas.
Four big clean energy companies that have reported results so far — inverter and battery maker Enphase, turbine manufacturer GE Vernova, electric vehicle giant Tesla, and developer and utility NextEra — mentioned tariffs prominently in either their earnings reports or their analyst calls. GE Vernova said that tariffs would result in $300 million to $400 million of additional costs. Enphase said that tariffs would take off two percentage points from its margin in the second quarter and six to eight points of gross margin in the third quarter. Tesla said that “increasing tariffs may cause market volatility and near-term impacts to supply and demand.”
Tesla’s executives — including chief executive Elon Musk — expanded on that market volatility later in a call with investors and analysts, with Musk saying that he was an “advocate of predictable tariff structures, free trade, and lower tariffs.” Musk added that economic uncertainty could continue to weigh on Tesla’s auto sales, which notably declined in the first three months of the year. “When there is economic uncertainty, people generally want to pause on doing a major capital purchase like a car,” he observed.
NextEra chief executive John Ketchum said the company had “dramatically diversified where we source our solar panels” and was not affected by the recent announcement of high tariff rates on solar panels from Southeast Asia. He also specified to analysts that “we source our wind turbines from the U.S., with manufacturing in Florida.” The company estimated that it has “$150 million in tariff exposure through 2028, on over $75 billion in expected capital spend,” Ketchum said.
Enphase chief executive Badri Kothandaraman attempted to tread delicately on the tariff issue. “While the global policy environment remains fluid with tariffs, with interest rates and subsidies constantly evolving, we are moving quickly to realign our supply chain to minimize downside across a range of scenarios,” he said. “While we cannot control the macroeconomic conditions, we can absolutely control our response.” GE Vernova chief financial officer Ken Parks described tariffs as a “continued increase in the cost base,” and said that the combined tariffs on steel plus various imports from Canada, Mexico, China — which is facing import duties of 145% or more, depending on the product — affect about a quarter of its spending.
A lot of that tariff impact comes from the battery supply chain, which China dominates. For Tesla, that means its fast growing energy storage business is particularly at risk. While the company has made some efforts to onshore stationary storage battery production, its chief financial officer, Vaibhav Taneja, said that domestic production would ultimately account for only a “fraction” of its battery needs, and even that would “take time.”
Enphase was similarly upfront about the impact on its battery supplies. “We are no exception. We use Chinese sources for the cell packs,” Kothandaraman said. He explained that thanks to the tariffs, making batteries domestically with Chinese cells “therefore turns out for us that whether we make it domestically or whether we make it outside the U.S., our costs are becoming approximately the same. And the cost impact is significant.” In other words, the tariffs make domestic battery production less appealing than it was before. Kothandaraman said that the company is working on establishing a non-Chinese supply chain, which will take six to nine months.
NextEra’s Ketchum said that the company had made “arrangements” to buy batteries made in the U.S. “for a significant portion of our backlog,” and that its contracts for non-Chinese-sourced batteries required the supplier to cover any tariff-related costs. Ketchum did say that the domestic batteries meet local content requirements for tax subsidies under the Inflation Reduction Act, however “there are certain components that come in from outside the United States.” Overall, Ketchum said, “our tariff exposure on batteries is expected to be negligible.”
All four companies are heavily exposed to various energy regulatory and subsidy plans that may or may not survive the double-whammy of the congressional Republicans’ budget-making priorities and the Trump administration’s desire to roll back environmental regulations.
Tesla’s revenue from emissions credits that other carmakers buy to comply with California’s fleet emissions standards was $595 million in the first quarter of this year, compared to $409 million of net income — implying that the company would have lost money if not for the credits. This Trump administration has already attempted to take away California’s ability to set emissions standards, as it did the first time around. Then it was not successful, and this time it might not have to be — the Supreme Court on Wednesday indicated that it would be open to a lawsuit from the fossil fuel industry challenging California’s limits.
Kothandaraman said that “the lack of certainty” around the fate of the Inflation Reduction Act, which is currently being hashed out in Congress, “is definitely a factor” in explaining what one analyst described as “a bit of paralysis on the customer side.” He was hopeful that “demand will be unlocked” once there’s “clarity” on IRA tax credits.
Meanwhile, GE Vernova said that offshore wind orders had fallen by 43%, “as a result of ongoing U.S. policy uncertainty and permitting delays.” It also took a $70 million charge related to the cancellation of a deal to supply 18-megawatt turbines in New York.
Musk bragged that Tesla’s Megapack utility storage system “enables utility companies to output far more total energy than would otherwise be the case,” and that “utility companies are beginning to realize this and are buying in our Megapacks at scale.” While the company deployed almost 40 gigawatt-hours of battery storage in the past 12 months — an impressive amount based on the current level of grid battery storage in the U.S. — Musk predicted that Tesla could end up deploying “terawatts” of storage on an annual basis.
NextEra has a large renewables development business, and Ketchum sees the uptick in demand for electricity as a boon: “When I look at the demand and the outlook in the renewable sector going … we just continue to see strong demand across the board, with hyperscalers being a nice sized part of that.”
GE Vernova competed with NextEra for the most investor-friendly demand growth story — though its is not a particularly climate-friendly one. The company says it has a backlog of 29 gigawatts of natural gas turbine orders, with an additional 21 gigawatts of reservations that will turn into future production. Its earnings before interest, taxes, depreciation, and amortization for its power business jumped from $345 million in the first quarter of last year to $508 million in the first quarter of this year, while its margins grew from 8.6% to 11.5%.
About a third of its reservations for turbines are for data centers, Scott Strazik, the company’s chief executive said. Some more were to provide baseload power. And the rest? “A healthy amount of these are also F-class gas turbines to just strengthen the durability and the resiliency on the grid,” he said.

The state is the first to backtrack on binding emissions legislation.
A wave of climate action swept the country’s statehouses in the early 2020s, with nearly two dozen states setting targets to slash their emissions. New York was ahead of the pack and among the most ambitious, passing the Climate Leadership and Community Protection Act, or CLCPA, in the summer of 2019 to achieve net zero emissions by 2050.
Now, however, the Empire State will distinguish itself as the first of the bunch to walk back its landmark climate law in the wake of Trump’s re-election.
The New York legislature released the text of the deal it reached with Governor Kathy Hochul to reform the state’s climate law on Tuesday. The deal includes two consequential changes: delaying a plan to regulate carbon from 2024 (it was already behind schedule) until 2028, and modifying how the state accounts for the powerful greenhouse gas methane in a way that will look like the state has accomplished deeper reductions than under the current method.
The governor has been signalling her intent to weaken the CLCPA for months, arguing that as written, it would have imposed untenable costs on New Yorkers. “Reality has been harsh,” she said during a press conference about the budget agreement in early May, before the text was released. “We cannot meet the current timelines without driving energy costs higher.”
Local environmental groups were widely critical of the deal, with New York Renews calling it a “major blow for New Yorkers and for the country” that would set “a dangerous precedent,” and Environmental Advocates NY deeming the rollbacks “bad politics and bad policy.”
Some remained hopeful that the changes would not derail the state’s progress by much, however. “There’s no way to sugarcoat it, this is a setback,” Jackson Morris, the director of state power sector, climate and energy for the Natural Resources Defense Council, told me. “At the same time, I don’t think it’s a setback that we can’t recover from.”
The CLCPA set targets to cut economy-wide emissions 40% by 2030 relative to 1990 levels, and achieve net zero emissions by 2050. It also codified an earlier plan to source 70% of the state’s electricity from renewable sources by 2030 and power the state entirely with zero-emissions resources by 2040.
New York didn’t make up these targets. They’re based on reports from the U.S. Global Change Research Program and the United Nations Intergovernmental Panel on Climate Change, which mapped out how the world could minimize the risks of climate change in line with the Paris Agreement. After Donald Trump announced he would pull the U.S. out of the Paris Agreement when he first took office in 2017, a number of Democratic governors banded together to show that America was still “all in” to achieve the pact’s goals, leading to a flurry of state climate laws in the years that followed.
Hochul’s budget deal doesn’t change the renewable electricity targets or the overall trajectory of the original law. Instead, it delays the regulations that would make the economy-wide emissions reductions possible to achieve.
The CLCPA directed state agencies to promulgate rules and regulations by 2024 that would put New York on the path to achieve the 2030 and 2050 targets. In the years since the law passed, the state has been developing a cap-and-invest program that would tax carbon emissions progressively over time, and use the proceeds to fund clean energy programs throughout the state. This program was the crux of Hochul’s affordability concerns, as it would make energy more expensive for some New Yorkers in the near term.
The budget deal moves the deadline for the regulations to the end of 2028. Crucially, it also does not require that those regulations help the state achieve the 2030 emissions target. Instead, it specifies that the regulations be designed to achieve a new goal of reducing emissions 60% by 2040, in addition to the original net zero by 2050 target.
Morris, of the NRDC, was quick to note that the deal does not get rid of the 2030 target. While there will be no state programs aimed at achieving it, it still provides a statutory foundation that agencies such as the Department of Environmental Conservation can point to as a reason to reject fossil fuel project permits, for example, he said. Meanwhile, Morris is optimistic that the new 2028 deadline and 2040 target can keep the state on track.
“We obviously prefer that none of this is happening,” he said. “But because it’s happening, I think that’s one aspect of this deal that we see as providing some ground to stand on.”
One of the aspects of the CLCPA that made it more ambitious than other state climate laws was the way it required New York to account for methane. The budget deal will eliminate this edge.
There were two key components to New York’s unique methane rules. The first was that they forced the state to take responsibility for methane emissions that occurred outside its borders that were nevertheless tied to its natural gas use. For instance, a major source of methane emissions is leakage from the infrastructure used to drill, process, and transport natural gas. New York banned fracking in 2014, and the state gets most of its natural gas via pipeline from Pennsylvania and West Virginia. Under Hochul’s changes, the state can take these “imported” emissions off its books.
The second is a bit more convoluted and has to do with how methane behaves in the atmosphere. When governments or companies set emissions targets, they typically convert all greenhouse gases into “carbon dioxide equivalents” so that they can set one round number goal for all emissions, like New York’s 60% reduction by 2040. There’s no single way to do this, since unlike carbon dioxide, which remains in the atmosphere for centuries, methane breaks down quickly. Over 20 years, one metric ton of methane has a similar effect to about 80 metric tons of carbon, but over 100 years, it’s more akin to 25 metric tons of carbon. New York uses the 20-year effect as its conversion factor, but under the budget deal, it will switch to the 100-year method. That will make its methane emissions suddenly appear much lower, and thus make the state look further along in fighting climate change without actually changing anything about its strategy.
This will ease the pressure on the state to electrify buildings, clean up landfills, and take other difficult steps to cut methane emissions. It will also, however, align New York’s methane math with that of most U.S. states and much of the rest of the world.
The national climate advocacy group Evergreen Action, which focuses on state policy, is less concerned about the changes to the climate law and more concerned about how they happened. Justin Balik, the nonprofit’s vice president for states, told me that Hochul never brought her concerns to environmental stakeholders or asked for policy proposals for how to accelerate clean energy while lowering costs.
“We need to see more urgency from the governor and the legislature to actually do the things that will result in emissions reductions and cutting costs for people,” Balik told me, “and less fretting about the targets that are written into law.”
Balik argued that the changes will do nothing to address the factors that are increasing energy rates. He cited the state’s dependence on natural gas as a key driver, as natural gas prices can fluctuate dramatically due to geopolitics and supply and demand. If anything, he said, delaying the cap-and-invest regulations will delay clean energy deployment and exacerbate affordability by deferring the revenue the state would have collected to and used to fund emissions-cutting programs and rate relief.
The budget deal attempts to make up for the shortfall with a $1 billion allocation to the state’s Sustainable Future Fund, which will support state programs to cut emissions from buildings and roads with heat pumps, thermal energy networks, electric school buses, and fast-charging stations.
Evergreen, NRDC, and other groups now have their sights set on the 2028 regulations.
“If we can move forward quickly with a robust process to stand up that cap-and-invest construct in New York State, and get it cutting pollution and generating billions of dollars in revenue for reinvestment in communities, that's going to be a huge breakthrough for the state of New York,” Morris said.
On a California chem leak, solar manufacturing, and BHP’s climate retreat
Current conditions: Unprecedented May heat is roasting Western Europe, with temperatures shattering records in at least 20 French towns and soaring to 95 degrees Fahrenheit in London • Bougainville, the autonomous and ethnically distinct region of Papua New Guinea that’s expected to vote for independence next year to become the world’s newest nation, is enduring a week of lightning storms and heavy rain • The Tajik city of Khorog, a provincial capital located in a canyon near the Afghan border, is bracing for snow.
The price per barrel of crude fell nearly 7% on Monday as Iranian negotiators arrived in Qatar for peace talks the same day two tankers carrying liquified natural gas passed through the Strait of Hormuz. The vessels shipping LNG from Qatar to China and Pakistan, respectively, successfully navigated the waterway at the mouth of the Persian Gulf on Monday. The signal of a loosening blockade comes two days after another tanker taking crude to China crossed the strait. While President Donald Trump said over the weekend that an agreement in principle to halt fighting with Tehran could come soon, The Wall Street Journal reported that it would take far longer to ease the bottlenecks created by the conflict. Despite reports of new U.S. strikes in Iran Monday night, prices fell another 4% in early trading Tuesday.
U.S. producers, meanwhile, are stepping up to fill the gap in oil and gas supply. On Saturday, the Financial Times reported that companies such as Diamondback, America’s third-largest producer in the Permian Basin, and shale driller Continental Resources were expanding drilling by more than 40% as a result of the war. U.S. companies have added at least 18 rigs since the start of the U.S.-Israeli bombing campaign. Increased production isn’t just happening at home, either. Exxon Mobil just began drilling a new offshore well near its new operations in Guyana, according to Upstream. Over at the British oil giant BP, however, this morning brought upheaval as the board of directors ousted its chairman after just six months.

California officials ordered as many as 50,000 Orange County residents to evacuate Sunday after a crack formed in a tank at an industrial facility holding 7,000 gallons of a highly flammable toxic chemical. The accident at the suburban Los Angeles plant owned by the British fighter jet supplier GKN Aerospace began on Thursday, when firefighters in Garden Grove, California, found that a tank containing methyl methacrylate, a feedstock used to make plastic, had started bulging with pressure and releasing gas as it overheated. By Saturday, a fissure had formed in the tank — one of three on site containing the chemical — in what NPR called “good news,” since the opening eased pressure, making an explosion less likely. So far, no one has been injured. “Safety at our facilities is paramount,” a GKN spokesperson told the Los Angeles Times. “We follow all standard safety protocols and processes and are regularly audited by numerous state and federal agencies.” But authorities as far east as Arizona were bracing for the possibility of an explosion. In an update posted on X Monday morning, Orange County’s interim fire chief announced that the threat of what’s called a “boiling liquid expanding vapor explosion,” or BLEVE (pronounced blevvy), “is now off the table,” adding that “that threat has been eliminated.”
While the accident will no doubt draw scrutiny to GKN’s record at the facility, known for producing parts for the Lockheed Martin F-35 fighter jet, the episode is unlikely to draw the same fervid response as the fire at California’s Moss Landing battery plant last January. That incident set off what Heatmap’s Jael Holzman pegged as nationwide backlash to batteries. So far, thankfully, cooler heads have prevailed in resisting the urge to demand a shutdown of all production of aircraft components as a result of an accident.
The Trump administration’s yet-undefined rules for determining a key factor in solar projects’ eligibility for outgoing federal tax credits are bifurcating the U.S. market. The administration has yet to spell out in detail how companies should determine what percentage of their project inputs come from a so-called foreign entity of concern. While the list of FEOCs includes Russia, Iran, and North Korea, the main sticking point for developers is China, which dominates the global renewables supply chain. On one side are developers willing to roll the dice on imported equipment. On the other are companies avoiding the risk by buying panels either made in America, or in allied countries. To make navigating the process easier, the SEMA Coalition — an industry group representing U.S. solar manufacturers that support restrictions on cheap Chinese imports — put out a new report that includes a check list to determine whether a panel producer is likely to qualify for federal tax incentives or not. The paper, which was shared exclusively with me for this newsletter, was “informed by tax opinions, legal counsel who advise the SEMA Coalition’s members, as well as public documents.” The findings show that “some of these rules are ambiguous, while others are clear but challenging to comply with in practice.”
As I told you last week, American solar manufacturing is finally seeing something of a boom. Nearly 30 new utility-scale solar factories began production last year, providing more than enough capacity to meet U.S. demand.

Amid a sweltering London heat wave in 2019, BHP laid out plans for the “biggest global mobilization since World War II” in the name of cutting back on fossil fuel use and fighting a climate that threat that “could be existential,” the world’s largest mining company’s then-CEO Andrew Mackenzie said at the time. Today, however, the giant is reversing course, quietly shelving billions of dollars in projects designed to cut emissions from its mining operations. An internal memo from last year leaked to Australia’s ABC News and The Guardian shows that the need for renewables at BHP’s iron-ore facility in Pilbara had “diminished,” and that a plan to hit net-zero by 2050 had a “low probability of success.”
The West Coast’s continental shelf drops off far more steeply into the Pacific than America’s East Coast slides into the Atlantic, making siting offshore wind turbines tricky off California’s shores. Nevertheless, a developer was trying to build the first floating offshore turbines in the U.S. — at least until the Trump administration struck a dubious deal to pay the company to quit. That agreement is drawing blowback from California regulators, as I told you earlier this month. But the Golden State isn’t abandoning its goals. On Monday, offshoreWIND.biz reported that the California Energy Commission had reaffirmed its target of 25 gigawatts of offshore turbine capacity by 2045. “At a time of global energy volatility, offshore wind is not just a climate strategy. It is part of a national security strategy,” Noel Hacegaba, chief executive at the Port of Long Beach, said in a statement. “The grid we built for the last century cannot carry us through the next. This is renewable energy’s moment.”
The market for offshore wind looks even brighter outside the U.S. Last week, the Danish Energy Agency received bids for two different offshore development areas totaling a combined 1.8 gigawatts of turbines, according to Renewables Now. In an interview with Wind Power Monthly, the chief executive of the automaker Volvo lauded Sweden’s offshore wind farms for giving manufacturers like his a “competitive edge.”
Canadians can now cruise around the 10,000-year-old Columbia Icefield in a vehicle whose pollution isn’t adding to polar melting. On Monday, InsideEVs reported that the truck maker Pursuit had retrofitted one of its old diesel ice explorers to go electric with a huge, 528-kilowatt-hour battery. That’s big enough for about 30 trips up and down the Rocky Mountain icefield. The renovation involved keeping the old cabin but replacing the chassis and driveline with battery-propelled equipment. It is the world’s first all-electric ice explorer.
Rob sits down with the Josh Parker, head of sustainability at America’s world-leading chip designer.
America’s tech companies are transforming the electricity system — building entirely new fleets of new solar panels, batteries, and gas turbines — in order to power what are essentially warehouses filled with cutting-edge chips.
Almost all of those chips are made by Nvidia. On this week’s episode of Shift Key, Rob is joined by Josh Parker, Nvidia’s head of sustainability. They discuss the climate and electricity impacts of artificial intelligence, why Josh is incredibly bullish on AI’s ability to cut carbon emissions and whether it has done so so far, and the company's work with clean energy and fossil fuel companies.

Here is an excerpt from their conversation:
Robinson Meyer: So Heatmap has been tracking what, to us, has been a very sudden and shocking rise of local pushback against AI data centers. And of course, this has become a larger meme over the past few months, as it’s gotten more attention. For instance, we think about 50 AI data centers or data centers broadly were canceled last year after facing local pushback. And we think more than 50 have already been canceled this year.
Are you seeing that at all at Nvidia? I mean, it doesn’t look — your quarterly results came out yesterday and they were, they absolutely blew out expectations. And so evidently it’s not affecting demand yet. But do you hear it from customers? Is this affecting Nvidia’s business at all? And how do you think about it as a risk going forward?
Josh Parker: So I’m aware of the sentiment, the paranoia around AI, mostly on a personal level because I see it on social media like other people do, as well. I’m not aware of any direct impact on our sales, so I can’t comment on that. But what I will say is, I do think it’s particularly tragic, because this technology has the potential to be the most beneficial, both for environmental goals and for social goals — so things like education and health care, and kind of across-the-board social issues benefit from AI, as well. And the concerns about AI, a lot of them are based on either erroneous data or old data. And I worry that some people don’t fully understand the net impacts, the positive as well as the negative of AI.
Plus, we have the uphill battle of, it’s really hard if the data center is being built a few miles down the road, to tie that data center — which, they don’t always look beautiful and things like that — to the benefits that the whole world is going to get from AI. So if — obviously not promising this — but AI could unlock cancer cures or cures to other diseases, and we’re seeing trends in the direction of cures and treatments and drug discovery and so forth. But it’s really hard for us as humans to draw a line between the infrastructure that we see down the street, and especially the speculative, the moonshot benefits. But even the more fundamental ones, like the benefits and productivity that we’re seeing in potential for wage growth and education and so forth, even though it’s hard for us to draw the line between the infrastructure.
So it’s understandable, but I do think it’s tragic. And I think it’s our responsibility in the tech industry to help people see the bigger picture and to address people’s concerns head on about environmental impacts and social impacts. Because the data really does demonstrate that, by and large, these data centers are pro-sustainability. They don’t have the impacts that most people are concerned about, and they’re manageable. And most data center operators are trying to operate them in a sustainable way.
