On Musk’s successor, a House vote, and Spain’s blackout

Current conditions: Flash flood warnings remain in place today throughout the south-central U.S. • Israel has requested international assistance in fighting large fires that have broken out in the hills near Jerusalem • May in Europe is off to a warm start, with temperatures in the mid-80s in Paris.
1. Tesla board began search for Musk’s replacement: report
Tesla’s board initiated a search for a chief executive to replace Elon Musk, The Wall Street Journal reported Wednesday night. With stock prices “vaporized,” car sales floundering, and dealerships becoming targets for public frustrations with the government, the board reportedly warned Musk that he needed to shift his focus from reform efforts in Washington and back to Tesla. At the time of the conversation, which happened “about a month ago,” Musk “didn’t push back,” the Journal writes, although Musk subsequently told investors on Tesla’s earnings call last week that he’d be “allocating far more of my time to Tesla.” While the board had reportedly advanced its search for Musk’s successor to the point of having “narrowed its focus to a major search firm,” the current status of the effort to find Musk’s replacement “couldn’t be determined.”
Musk has complained to those close to him that he is “frustrated to still be working nonstop” at Tesla, and has made public comments about his compensation. He spent more than $250 million on Trump’s re-election campaign, although his company faces substantial hurdles due to the president’s policies, including a significant hit from tariffs and a loss of competitive advantage if California’s ability to set vehicle emission standards stricter than the federal government’s, which has generated significant revenue for Tesla in the form of compliance credits it’s sold to other automakers, is revoked.
2. House strikes down California’s clean truck rule, cueing up clean air vote
The House of Representatives voted 231 to 191 on Wednesday evening to revoke California’s ability to incentivize clean truck purchases, a prelude to Thursday’s vote over whether or not the state can set stricter auto emission standards than the federal limits. Thirteen moderate Democrats, including Henry Cuellar of Texas, Susie Lee of Nevada, and Tom Suozzi of New York, joined Republicans in voting to block California from requiring truck dealers to sell an increasing number of zero-emission medium- and heavy-duty vehicles over time. In a separate vote on Wednesday, the House revoked another of California’s standard-setting capabilities, designed to cut down on nitrogen oxide emissions, which Republican Morgan Griffith of Virginia described as “an effort to truly vilify diesel engines.” The measures will now be sent to the Senate.
California’s authority to set these rules comes from waivers it’s been granted by the Environmental Protection Agency under the Clean Air Act, which otherwise compels states to adhere to federal standards. The Clean Air Act also allows other states to adopt California’s standards, giving the state extraordinary influence over the automotive market.
The marquee vote, however, will come on Thursday, when the House will vote to end California’s vehicle emissions waiver, which some critics have erroneously characterized as an electric vehicle mandate. Many are skeptical, however, that Congress has the authority to revoke the waiver under the Congressional Review Act. Senate parliamentarian Elizabeth MacDonough has previously said the waivers do not qualify under the CRA and “ignoring that ruling would buck decades of precedent under presidential administrations of both parties, and would lay the foundation for potentially tricky legal fights down the road should a future president decide to grant California a new waiver,” journalist Clark Mindock writes for Landmark.
3. Debate rages over whether Spain’s renewable energy dependence caused Iberian blackout

Monday’s 18-hour blackout across Spain and Portugal has sparked a fierce and ongoing debate over whether the Iberian Peninsula’s heavy reliance on wind and solar energy is to blame. While the investigation into the cause of the blackout is still ongoing, we do know that at the time of the outage, Spain’s grid “had little ‘inertia,’ which renewables opponents have seized on as a reason to blame carbon-free electricity for the breakdown,” my colleague Matthew Zeitlin explains. In essence, gas turbines and nuclear plants have inertia that comes from spinning metal, such as a turbine, which can provide the system with a little more momentum if a generator drops off the grid. “Solar panels, however, don’t spin,” Matthew adds — hence the current line of attack by energy transition skeptics.
On Wednesday, the president of Spain’s national grid operator, Red Eléctrica, insisted that “linking what happened on Monday to renewables isn’t correct.” Spain’s prime minister, Pedro Sánchez, has likewise claimed that “Those who link this incident to the lack of nuclear power are frankly lying or demonstrating their ignorance.” But as Matthew writes, it wouldn’t necessarily be a surprise to learn that a renewables-heavy grid struggled with maintaining reliability due to low inertia — nor is it an insurmountable challenge. Read more about how inertia may have played a part in the blackout here.
4. Equinor considers ‘legal options’ against the Trump administration over canceled wind farm
Equinor, the Norwegian state-owned energy company behind Empire Wind, is reportedly considering suing the Trump administration after the Department of the Interior canceled its Long Island offshore wind farm last month. As my colleagues Emily Pontecorvo and Jael Holzman reported at the time, Empire Wind was “the second fully permitted offshore wind project” to be targeted by the administration, and its potential cancellation represents “a huge blow to New York State’s climate and clean energy goals.”
Equinor has already spent nearly $2 billion on Empire Wind, which was almost a third complete at the time Interior Secretary Doug Burgum ordered an immediate halt to construction. The company is now “considering its legal options,” The Guardian writes, and “may take Donald Trump’s administration to court.”
5. India braces for potentially deadly slate of spring heatwaves
India is preparing for a series of heatwaves in May that could potentially strain power grids and lead to dangerous blackouts, Bloomberg reports. The warning — issued on Wednesday by the director general of India’s Meteorological Department, Mrutyunjay Mohapatra — follows what was already a difficult April in the country, with temperatures in New Delhi spiking above 100 degrees Fahrenheit earlier in the month. In Jaipur, temperatures have already broken 110 degrees, leading outdoor laborers to suffer from heatstroke. Mohapatra confirmed that above-average temperatures are expected to persist over most of the country between now and the onset of the monsoon season in June, except in some parts of the southern and eastern states. Spring heatwaves in India have been linked to climate change, with Gianmarco Mengaldo, a climate expert at the National University of Singapore and author of one such report, telling The Guardian, “Many of the events predicted for 2050 or 2070 are already happening. We underestimated the speed of change.
Ministers in the UK are considering a new rule that would require almost all new homes to have rooftop solar.

With a permitting deal seemingly on the horizon, Republican Gabe Evans and Democrat Scott Peters may be about to see their partnership pay off.
The fate of permitting reform legislation that could smooth the way to all kinds of new and improved energy infrastructure — including transmission lines and renewables — is currently hostage to opaque discussions between Senate committee chairs. Rhode Island Senator Sheldon Whitehouse, the Democratic ranking member of the Senate Environment and Public Works Committee, told a Rhode Island business group earlier this week that “we’re actually in a pretty good place on permitting reform,” and that there was “maybe another week of negotiations.” Whitehouse’s Republican counterpart on the EPW committee, West Virginia Senator Shelly Moore-Capito, told Semafor on Friday that any bill has “got to pop out of here in the next 48 hours.”
If that’s going to happen, it will be because Republicans and Democrats have decided it’s worth it to get along. Any deal will eventually have to be voted on by the House, which has already produced several bills on a bipartisan basis, and even passed one — the SPEED Act — late last year.
Two of the busier House members on this issue are Scott Peters, a Democratic former environmental lawyer from San Diego, and Gabe Evans, a first term Colorado Republican representing a suburban and rural district north of Denver that includes wind farms and crude oil production. “The district that I represent truly is an all of the above energy district,” Evans told me.
Their latest effort is a bill aimed at smoothing out permitting for transmission development, especially interregional transmission. Last week, the two congressmen unveiled the CLEAR Act, seeking to apply a stricter set of standards for lawsuits against transmission projects that aligned with how natural gas and hydropower projects are treated under the Federal Power Act (it’s much harder to sue to stop these projects). Earlier this year, the two also sponsored the CERTAIN Act, a more comprehensive streamlining of federal permitting for energy infrastructure projects.
“We’re proud to have a lot of our work as the foundation for this, and I think if they send us over something that includes this, it’s got a really good chance of passing in the House,” Peters told me. Evans added that bringing forward bipartisan bills “gives a little bit more impetus to the Senate to know that the House is looking for these things.”
While the Senate’s deal will be up to the senators, Peters told me he envisions a broad permitting package that could include reforms to the National Environmental Policy Act to shorten permitting timelines, preventing the president from nixing individual projects, and reform Section 401 of the Clean Water Act which effectively devolves power to tribes and states to block a variety of interstate projects. “I think it’s coming together pretty well,” Peters said. “Obviously, we’re waiting for white smoke from the Senate.”
A permitting reform package may be one of the last major bills several bipartisan-minded House members get to vote on.
Election day is about six weeks off, and while Peters will likely have an easy time getting reelected for this eighth term, Evans is in a tough race. His purple-hued district is a target for the House Democratic campaign arm, which is hoping to flip it to former Colorado House of Representatives member Manny Rutinel, who worked as a lawyer at the environmental group Earthjustice. The Cook Political Report rates the race as toss-up, and Nate Silver gives Rutinel a roughly 75% to win.
But Rutinel won’t be getting any campaign help from Peters.
When I asked Peters about the timing of releasing a bill that could boost an endangered Republican’s bipartisan bona fides less than two months before an election, Peters told me that he and Evans had been working on it “for a while,” and that “my colleagues know that I’ve worked with Republicans to get problems solved.”
He said he wasn’t “participating in Gabe’s election” and wasn’t giving any money to his campaign, but also that he wouldn’t campaign Evans’ challenger, despite the opportunity to bolster his own caucus.
Peters is not shy about praising Evans. “What I appreciate about Gabe is that it takes a little bit of initiative to separate yourself from the majority — particularly when you’re in the trifecta — and do your own thing. He’s been a good partner in helping find ways to reduce process and make things go faster,” he told me.
Evans told me that he and Peters met early in this Congress, as Evans was getting settled into his new office in the Longworth building. “We’ve built the relationship over the last two years with a lot of the different areas that we’ve collaborated on.”
“I always try to meet the members of my committee and find out who will work with me. And I was fortunate to find Gabe,” Peters said.
“I do want to win the majority in the next Congress,” Peters went on, but “the norm should be that we figure out ways to work together to solve problems, and, you know, we’ll let the voters of Colorado 8 decide who to send me.”
Evans, for his part, told me that he had to work with Democrats to get anything passed as a member of a minuscule Republican minority in the Colorado statehouse, and that the 40-plus members of the bipartisan Problem Solvers Caucus have agreed not to campaign against each other. “There’s 385 other members that you can go pick fights with,” he said.
A new analysis by a one-time atomic energy opponent makes a bull case for big reactors.
If you know anything about the cost of nuclear energy in America, you probably are aware that the most recent reactors built — the only two new ones designed, planned, and constructed since the 1990s — were budget busters. Units 3 and 4 of Southern Company’s Alvin W. Vogtle Generating Station in eastern Georgia were the first of a new generation of reactor technology ever to be deployed in the U.S. Construction delays, changes to the design, and corporate bankruptcies ultimately sent the price of the pair of Westinghouse AP1000s — the Ford Mustang of American nuclear technology, with safety features that essentially make them not just powerful but also meltdown-proof — to nearly $40 billion, or about $16,350 per kilowatt.
But the U.S. once built reactors for half that — and it did so in the chaotic aftermath of the nation’s worst civilian nuclear accident, when mounting regulations made atomic power construction more onerous than ever before.
That’s the landmark finding of a new report by a veteran nuclear researcher, who quantified and broke down the cost of constructing nearly every civilian atomic power station the U.S. built in the 20th century. Adjusting the dollar figures using the Handy-Whitman Index, a specialized formula for calculating inflation in the utility sector’s construction costs, the analysis — shared exclusively with Heatmap — concluded that 47 reactors built in the U.S. between the 1979 partial meltdown at Pennsylvania’s Three Mile Island nuclear plant and the turn of the millennium came in at an average of $8,200 per kilowatt.
“Costs are only going to come down from that,” Charles Komanoff, the economist and energy policy analyst whose consultancy conducted the study on behalf of the Clean Air Task Force, told me.
The paper carves out a pathway down the cost curve that runs counter to the industry’s broader consensus at the moment on the best way to make nuclear less of a luxury choice compared to other generating sources. Billions of dollars have flooded into companies promising to commercialize small modular reactors that generate 300 megawatts or less. The concept is a bet on what Komanoff calls the economies of duplication, meaning that if customers need more individual reactors, developers can ride that repetition to lower prices. But the paper suggests that the way developers have historically reduced nuclear costs — through economies of scale — achieves the same per-kilowatt savings with one gigawatt-sized, water-cooled reactor as 20 smaller reactors would net.
Some small and microreactor developers say that using alternative coolants — molten salt, liquid sodium, high-temperature gases such as helium — could further raise the efficiency of their technologies, allowing them to make up for whatever they lose on economies of scale. But large, traditional reactors such as the AP1000 are “a proven technology” that, unlike next-generation reactors with far less operating experience, won’t have to overcome “teething problems” to reach maximum efficiency levels, Komanoff told me.
There are other options to the AP1000, such as the ABWR that the parent companies of GE Vernova Hitachi Nuclear Energy built in Japan and Taiwan in the 1990s. One was planned for Texas, but abandoned a decade ago amid declining interest in nuclear power post-Fukushima. The technology is approved by the NRC, but GE-Hitachi has since turned its attention to its 300-megawatt BWRX-300. Given that no ABWR was built in the U.S., James Boucher, the former Deloitte nuclear consultant who co-authored the paper, said the AP1000 is the reactor best positioned to replicate the country’s successful buildout of the 1980s.
“We have two AP1000s. They're fully built. They’re operating. They’re doing, as far as I can tell, quite well. And they are like these reactors in our sample,” Boucher told me. “If we wanted to build 20, 30, 50 more AP1000s, I think we’d have a good shot.”
The Nuclear Company, a startup developer that hired much of the team behind the Vogtle buildout in a bid to become the go-to project manager for future AP1000s, called Komanoff’s report “promising because it demonstrates how cost can come down when we don’t focus on building first-of-a-kind projects.”
“There was a 30% overnight capital cost reduction just moving from Unit 3 to Unit 4 on the Vogtle project — there is no reason we can’t continue down the learning curve on the next AP1000s built in this country,” Joe Klecha, The Nuclear Company’s chief nuclear officer and president, told me after reviewing the report I sent him. “Especially with our mix of experience building these reactors and advancements in technology we’re leveraging to scale, achieving below $10,000 per kilowatt is just the beginning for us. We believe we can execute safer, faster, and at lower cost than we’ve achieved in the past.”
Back in the 1980s, the military-like regimentation common at nuclear plants and construction sites wasn’t yet as ingrained in the industry. The Nuclear Regulatory Commission had replaced the Atomic Energy Commission, which was seen as too deferential to the companies it oversaw, and spent the decade tightening rules on constructing and operating nuclear plants. New accident scenarios were being discovered, requiring new plants and existing ones up for relicensing to change operating protocols, upgrade equipment, and conduct additional research.
Komanoff was among those pushing for the changes. In reports he authored on behalf of Greenpeace, an arch opponent of nuclear power, he dissected the fiscal woes atomic energy developers faced, making the economic case for shutting down electrical stations that his fellow activists battled on ecological or moral grounds. Eventually, Komanoff moved on to advocating for a carbon tax as the fairest and clearest way to guide the economy away from fossil fuels and toward decarbonization. While serving as director of the Carbon Tax Center, which he co-founded, he noticed a trend among nuclear plants: They were getting better at operating.
The regulatory changes that followed Three Mile Island succeeded in raising the operating efficiencies of nuclear plants. In the 1970s, reactors had a capacity factor — a measure of how frequently a generating source actually produces electricity — of about 50%. Yet by 1991, that number had risen to 70%, putting atomic energy on par with the most efficient fossil fuel and hydroelectric plants. In 2002, that national average hit 90%. In 2019, it rose to 94%. When the final reactor at Indian Point, the nuclear station that served Komanoff’s native New York City, closed in 2021 due to political opposition to its relicensing, it had just set a world record for an uninterrupted 753-day run of electricity production.
Gradually, Komanoff came to see nuclear power as a vital tool for decarbonization. But, ensconced in the climate movement through his carbon tax advocacy, he found it easier to stay mum on his conversion, lest he ruffle the feathers of fellow activists who remained stalwart anti-nuclearists. After all, he thought, if a carbon tax passes, nuclear plants will benefit, so why bother speaking up specifically for atomic energy? Indian Point’s early shutdown, however, caused Komanoff pangs of regret.
“It just forced me to confront the consequences of not advocating for nuclear power,” he said. “I felt the way I imagined I would feel if a climbing partner — I used to be a sort of mountaineer — had died because of some negligence on my part. I really took personal responsibility because I imagined that — and maybe I’m just in a complete fantasy about my shamanistic power — as someone who had argued 40 years ago for shutting Indian Point, that if I had gone public say ‘Don’t do it,’ that I might have been able to begin turning the tide.”
While $8,200 per kilowatt is half of what Vogtle cost, it’s still nearly four times the cost of building a new natural gas-burning power plant with combined-cycle turbines, which itself rose to $2,157 per kilowatt last year from less than $1,500 in 2023. But the “regulatory churn” that kept the price of nuclear high, Komanoff said, is unlikely to return for new nuclear plants using proven designs such as the AP1000.
“Part of my optimism about nuclear being less subject to regulatory churn going forward is because it’s not a whipping boy,” he said. “It’s really hard to overstate the aura of incompetence that surrounded the nuclear power sector in the United States in the ‘70s into the ‘80s. But when you’ve got plants that are averaging 90% or higher capacity factors, things change.”
Current conditions: Oman’s Ayn Athum Waterfalls burst to life this week as rain battered the Gulf nation’s southwestern Dhofar governorate • Severe monsoon flooding has deluged parts of the American Southwest, including Navajo Nation, where at least three people have died • Tropical Storm Dujuan is barreling toward Japan, where it threatens flooding and landslides in Tokyo and Chiba.
When the Houthis stormed Yemen’s Red Sea coast last week, the Iran-backed rebels gained new ground from which to attack boats passing through the vital shipping lane, extending Tehran’s reach from the Persian Gulf’s hotly contested Strait of Hormuz to the waterway on the opposite side of the Arabian peninsula. In response, oil prices surged. But the price per barrel of crude is slipping again as the United States has rebuked Saudi Arabia’s requests for help routing the militants, instead seeking a deal that keeps the Bab al-Mandab Strait open to American and Israeli ships. Over the weekend, U.S. diplomats met with Houthi officials in neutral Oman, Reuters reported. Following the talks, the Times of Israel reported that Houthis promised not to attack any Israeli or commercial ships of any kind, only those linked to Saudi Arabia, which has funded the Yemeni government’s campaign against the rebels.
Satellite images published by the investigative site Hunterbrook showed workers building a bypass on Saudi Arabia’s East-West Pipeline, its main conduit for circumventing oil exports around the Strait of Hormuz, to get around the pumping station damaged by a Houthi attack. But the promise of free movement through the Red Sea sent the price of oil down by between 1% and 4% on Thursday.
Just yesterday, I told you that the Trump administration had moved to drastically change how the government interprets the Endangered Species Act to only consider deaths of protected animals illegal if the creatures were intentionally targeted. Such a shift would exclude the vast majority of deaths linked to energy companies, such as when birds land in toxic oil ponds or collide with wind turbines. Whether federal enforcement ultimately reflects that interpretation depends on the outcome of a forthcoming lawsuit. Already, Earthjustice has vowed to file litigation challenging the Trump administration’s legal memo directing federal agencies on its new view of the nation’s bedrock conservation law. “The government’s new legal position is a prescription for extinction. It says that as long as you claim you didn’t mean to kill an endangered species, the law can’t and won’t stop you,” Earthjustice attorney Ben Levitan said in a press release. “That’s ridiculous — and a totally illegal, active misreading of the Endangered Species Act. We’ll see the Trump administration in court about this.”
The toll wind turbines take on migratory birds is a favorite talking point of the energy source’s opponents. But relief from the responsibility to avoid killing birds would be cold comfort to the wind industry as developers wait for the Trump administration to follow a court ruling requiring it to continue processing applications for turbines. As my colleague Jael Holzman wrote yesterday, the administration has continued delaying. At least one other legal fight within the offshore wind industry has, meanwhile, come to a conclusion. Vineyard Wind and its turbine supplier GE Vernova, announced an “amicable settlement” this week that resolves “all outstanding litigation,” the New Bedford Light reported. The developer sued the supplier in April, accusing GE Vernova of an $800 million breach of contract following a blade failure in 2024.

The U.S. needs more long-term energy storage, and few technologies are better tested by time than using excess electricity to pump water into a reservoir, where it can be released downhill and run through turbines to generate huge bursts of power when it’s needed. Back when the U.S. had lots of nuclear power, pumped hydro plants harvested the unused electrons during the night. With solar now producing more electricity during the day in some parts of the country than the grid demands, pumped hydro is seeing a potential renewal. But the U.S. hasn’t built any pumped hydro facilities since the 1990s. A project that looked likely to break that dry spell is now on pause as the Trump administration heeds opponents’ concerns and orders a new study on its environmental impact.
The Federal Energy Regulatory Commission has delayed its decision on whether to license the $3 billion project to add a pumped hydro facility to the Seminoe Reservoir, a lightning bolt-shaped waterway in southern Wyoming. The Bureau of Land Management said it will conduct a supplemental environmental impact statement and open the door to more public comments and input from local officials. “This feels like a small victory,” CiCi Oliver, a fly-fishing shop owner who opposed the project over its potential disruptions to the ecology of the reservoir, told WyoFile this week.

At the start of the Iran War, some interpreters of President Donald Trump’s supposed four-dimensional geopolitical chess moves suggested that shutting down the Strait of Hormuz was an intentional move to show China’s vulnerable underbelly: Beijing’s dependence on oil imports. And yet, China’s vast oil stockpiles and refining capacity, plus its array of alternative energy sources, allowed the country to slash oil purchases by 23% in the first six months of the war compared to the same period last year, according to a New York Times analysis of customs data. “This is a power that nobody thought China had,” said Erica Downs, a senior research scholar at Columbia University’s Center on Global Energy Policy. “Going forward, it’s going to be really interesting to see: What does China do with this newfound power?” The heaviest answer to that question now weighing on Western officials involves China considering the ramifications of a potential invasion of Taiwan to be less worrying than before.
That’s especially true because Taiwan, by contrast, is more vulnerable to losing access to oil and gas imports than ever before. After completing its decades-long mission last year to shut down the nuclear fleet that powered the island’s 20th century transformation into the world’s premiere chipmaker, Taiwan’s ruling Democratic Progressive Party — which advocates for the republic’s continued de facto independence — left the nation dependent on imported liquified natural gas and crude for the vast majority of its energy. Now, according to Nikkei, the government is hastening its efforts to potentially bring at least one nuclear station back online.
Yet another state is considering a moratorium on data centers — one close to the epicenter of the artificial intelligence boom. Maryland, which shares a grid and a border with northern Virginia’s data center megacluster, could see a ban come into effect as early as next year if state legislators pass a bill in the next session. Governor Wes Moore, a Democrat, said he “will absolutely sign” a statewide ban “if it’s coming from local legislators.” Speaking to Punchbowl News, he suggested that any moratorium would come with loopholes for projects that meet high standards. “I believe local jurisdictions should have a say. There are certain local jurisdictions who want it,” he said. “I just need them to understand I have very strict guidelines for what is actually going to get state approval.”
A startup founded by members of the team of U.S. government scientists that first achieved net-energy gain from a fusion reaction has hit a new milestone that should raise the eyebrows of even skeptics of the so-called holy grail of clean power. Less than two months after publicizing its roadmap to commercial fusion, Inertia Enterprises ran a simulation demonstrating that its first commercial plant will be capable of producing 25 times more energy than the laser needed to trigger the reaction, the company told my colleague Katie Brigham in an exclusive.
