On Meta’s atom, Illinois frees nuclear, and China’s fusion milestone

Current conditions: Snow is heading for the Northeast later this week, with some flakes in New York City on Thursday • A heatwave in central Argentina is driving up temperatures to 102 degrees Fahrenheit • A blizzard is set to dump nearly 3 feet of snow along Hokkaido’s Sea of Japan coast.
The United States’ biggest oil company is brushing off President Donald Trump’s promise to restore Venezuela’s drilling industry to its former glory under American stewardship. In an address to the White House on Friday, Exxon Mobil Corp. CEO Darren Woods said that Venezuela’s
current “legal and commercial constructs” and “frameworks” make the country “uninvestable.” The country’s basic systems need “significant changes,” and its hydrocarbon laws need to be overhauled before the Texas behemoth thinks it can put money into rebuilding the infrastructure in the South American nation. Still, Woods said he was “confident that with this administration and President Trump working hand-in-hand with the Venezuelan government that those changes can be put in place.” As my colleague Robinson Meyer noted in a recent interview for the Shift Key podcast, Trump’s push for imperial resource ventures generally might be a tough sell for actual oil companies.
Exxon’s main U.S. rival, the No. 2 producer Chevron Corp., has invested heavily in Venezuela over the years. Exxon, by contrast, has developed what’s considered the most significant new oil patch in the world, the offshore drilling operations in Guyana. But Exxon still benefits from the Trump administration’s intervention in Caracas. Venezuela has long argued that Essequibo, the sparsely populated jungle province comprising the western half of Guyana, rightfully belongs under Caracas’ rule. The move to threaten Essequibo and Exxon drilling platforms off its waters with the Venezuelan military in recent years drew fierce blowback. Now it seems unlikely such agitation will happen again anytime soon. Meanwhile, Trump said Sunday he may exclude Exxon from the Venezuela spoils, claiming “they're playing too cute.”
Until now, Meta has been the most cautious nuclear investor of its tech peers, brokering just one major deal to buy power from an existing atomic power station. By contrast, Amazon bought a stake in the reactor developer X-energy and put up the money for its first power plant; Microsoft pumped billions into reopening the working reactor at Three Mile Island; and Google is both bringing another reactor back online and investing in the next-generation reactor company Kairos Power. On Friday, the Facebook owner announced a sweeping deal to buy power from the nuclear utility Vistra, help build reactors with the Bill Gates-backed startup TerraPower, and pay cash upfront to finance the purchase of fuel for microreactor developer Oklo’s first power plants in Ohio. “Our commitments to Oklo and TerraPower support the next generation of American developers creating safer, advanced nuclear reactors and accelerating the development of nuclear technologies,” the company said in a statement. “Through our partnership with Vistra, we’re providing financial support for operating nuclear power plants, extending the operational lifespan.”

Illinois is the most nuclear-powered state in the nation, with atomic stations supplying nearly all of Chicago’s power at times. Yet the state put a moratorium on new reactors in the 1980s. That is, until last week when Governor J.B. Pritzker signed legislation lifting the ban. In 2023, Pritzker signed a bill that would allow for construction of more speculative technology, like small modular reactors, but maintained the ban on large-scale units. At the time, the Democrat vetoed separate legislation to legalize large-scale reactors, insisting they “are so costly to build that they will cause exorbitant ratepayer-funded bailouts.” Since no one has yet built an SMR in the U.S., there’s no way of really knowing how much the smaller units will cost. But more recent research by the Massachusetts Institute of Technology’s Koroush Shirvan finds the opposite. Building another gigawatt-sized Westinghouse AP1000 — the same type of machine that had major cost overruns in Georgia over the past decade — would be cheaper than building a first-of-its-kind SMR, since the supply chains and design are established.
“It’s striking that the same rationale Gov. Pritzker used to veto lifting the nuclear moratorium in 2023 — the prospect of new large-scale reactors in Illinois — is now being celebrated by his administration as a major win,” Madi Hilly, the managing director of the Chicago-based consultancy Radiant Energy Group, told me for this newsletter. “This reversal is a positive signal for future growth and long-term prosperity in Illinois.”

China went from spending virtually nothing on nuclear fusion in 2021 to investing more than the rest of the world combined, as I told you last month. Well, it’s working. Last week, China’s leading fusion project, the Experimental Advanced Superconducting Tokamak, or EAST, pulled off a “novel high-density operating scheme” in the reactor. In the past, exceeding the limits of how dense the plasma that powers the fusion reactor could get ended up causing disruptions. “The findings suggest a practical and scalable pathway for extending density limits in tokamaks and next-generation burning plasma fusion devices,” study co-lead author Ping Zhu, an engineering professor at the University of Science and Technology in China, said in the statement to Live Science.
China plans to end its value-added tax export rebate on solar products on April 1. The finance ministry said the VAT export rebates for battery products will fall to 6% from 9% between April and December and phase out entirely at the end of this year. In a statement on the change, the China Photovoltaic Industry Association acknowledged that some Chinese exporters were, as Reuters put it, “using rebates as a price discount for foreign buyers.” This won few friends in Europe or North America, where governments who wanted strategic solar manufacturing industries saw factories close in the face of overwhelmingly cheap Chinese imports. Analysts told the South China Morning Post the policy is a signal “that Beijing is interested in serious trade relations and is a good partner.”
Biodegradable plastics are not always safer for rivers and oceans. When researchers at East China Normal University compared how microbial cities formed on the surfaces of traditional plastics and biodegradable materials after 88 days in a tidal river in Shanghai, they found that drug-resistant bacteria proliferated on both non-biodragable and biodegradable plastics, but saw a particularly intense but short-lived spike in pathogens developing on the so-called greener material. “Our findings show that biodegradable plastics do not simply dissolve into the environment without consequence,” Yinglong Su, the study’s lead author, said in a statement. “They create a different kind of risk that peaks during degradation and should not be ignored in environmental policy.”

Before that can happen, though, we need megawatt chargers.
The electrification of semi trucks started with baby steps. First came EV semis for short-haul routes, those where the vehicle can do all its business on a single charge. We’re talking big rigs that make drayage runs to ferry shipping containers between ports and nearby warehouses, or delivery vans that spend their day puttering around the city.
It makes sense. Semis are huge and heavy; it takes a long time to charge a big enough battery to move one. That first batch of EV trucks could return to base and recharge their batteries overnight, with no rush to get them right back on the road. But for electric semis to make regional runs — and someday national ones — they need fast-charging truck stops that can deploy much more juice than an ordinary passenger EV requires.
That infrastructure is coming. At last week’s ACT Expo in Las Vegas — where trucking and fleet professionals trade notes on how electrification, advanced fuels, and AI — the conversation centered on the rise of megawatt charging, tech that will make it possible for electric trucks to make runs that are viable only for diesel-powered trucks today.
Most EV semi truck charging to date has been done at speeds of up to 350 kilowatts. That’s fast for a passenger vehicle. Hyundai, for example, claims that a car like the Ioniq 5 can go from 10% to 80% charge in around 15 minutes. But a semi’s energy requirements are a different ballgame. At those speeds, a truck needs hours to top off — unacceptable for a trucker on a tight schedule.
The next step, megawatt charging, is a misnomer. Technically, this category includes any charger over 600 kilowatts, though it stretches up to 1.2 megawatts. That is the theoretical maximum of the Tesla Megacharger, the high-speed charger built specifically for the Tesla Semi that has just gone into mass production. The 1.2-megawatt version is promised to fill about 60% of the truck battery in about half an hour (the duration of the mandated break a trucker must take after eight hours on the road). Henry Johnson of Alpitronic, a company building out high-powered charging in Europe, said even just 700 to 800 kilowatts is enough to charge trucks with all the juice they’ll need for the rest of their journey in about 45 minutes.
Indeed, megawatt charging has already taken root in Europe, which is ahead of the United States in EV trucking (one of the ACT panels was titled, “Megawatt Charging in Europe: Lessons for the U.S. Market”). The availability of such speeds will soon accelerate here, though. “Megawatt charging is coming this year,” said Patrick Macdonald-King, CEO of the Daimler-backed group Greenlane that is set to build a network of electric and hydrogen refueling stations for trucks in America. “We’re not building anything without it,” he says.
Greenlane has a flagship station open near San Bernardino, California, including a couple dozen plugs at around 400 kilowatts, but future stations planned to service trucks traveling between L.A. and Phoenix or Dallas and Houston will feature megawatt-speed plugs. Tesla has built Megachargers stations at its factories and opened one specifically for Pepsi, an early adopter client. Its first public megawatt charging station in the Inland Empire, the urban sprawl inland of Los Angeles, opened for business in March.
Part of what makes this leap possible is the plug. Existing EV trucks have used the CCS charging standard, but an increasing number of them are now equipped to work with MCS, the Megawatt Charging Standard, which can reach speeds beyond CCS. The MCS plug is not only fast, it’s also unique to big trucks, which negates current problems such as a semi truck pulling up to a charging station only to find that a CCS-using passenger car is hogging the plug.
The megawatt era could also lead to consolidation that makes it simpler to expand semi charging around the country. There’s a case to be made for both the CCS and MCS plugs to stay in use, with CCS serving the cheaper, slower kind of charging that some need. But just as passenger EVs have now almost universally coalesced around the NACS plug that Tesla invented, the same thing could happen for MCS. Tesla, for example, is offering a 125-kilowatt Basecharger for companies who want Tesla Semis but don’t need the power of a 1.2-megawatt Megacharger, with the less powerful option going for $40,000 rather than $188,000. But it, too, uses only MCS. John Smith, incoming CEO of the spun-off company FedEx Freight, called for as much during his conference keynote. “We need a universal standard,” he said. “Every truck must be able to go to every charger.”
It will be years before there is a nationwide patchwork of megawatt truck stops along all of America’s major highways, the kind that exists now to make it possible to drive nearly anywhere in this country in an electric car. The good thing about trucking, though, is that it’s predictable. You don’t need to build a whole network of chargers anywhere ordinary citizens might want to drive. You only need it where you already know trucks are destined to go.
Providing fast-charging on heavily used freight corridors in California and Texas can allow fleets to electrify those routes — and see a preview of life with the benefits of electrification, such as more predictable maintenance and the freedom from wartime diesel price shocks.
Invest in Our Future’s Peter Colavito on why funders and advocates should pay more attention to the solar farm down the road.
Up until last September, Wisconsin’s Public Service Commission had gone 14 years without approving a large-scale wind project. But when they met to review the 456 public comments submitted for Badger Hollow, a 118-megawatt project that would straddle Iowa and Grant counties, they found overwhelming support for the proposal. Approval followed.
This wasn’t by chance. For months, groups like the Rural Climate Partnership, Greenlight America, Farm-to-Power, Clean Wisconsin, CivicIQ, and Healthy Climate Wisconsin worked together to build support. They held roundtables with farmers and shot digital ads with testimonials from residents that ran online and at gas stations. They emphasized the nearly $600,000 the project would generate for cash-strapped towns and counties every year to fund things like roads, bridges, and emergency services. And they empowered trusted local voices to make a case grounded in their communities’ values.
The breakthrough in Wisconsin shows how investing in local interventions can accelerate the energy transition — and points the way forward for clean energy advocates trying to navigate federal headwinds.
As skyrocketing electricity demand and soaring costs draw attention to our power systems, clean energy offers a formidable solution. Wind, solar, and storage technologies have matured enough that they can be built quickly and cheaply virtually anywhere, for anyone, at any scale. And now, as the world contends with yet another conflict roiling fossil fuel markets, these energy sources offer a shield from volatility.
Given these clear advantages, it’s worth asking, “Why aren’t clean energy projects moving forward faster in more places?”
Our team at Invest in Our Future has learned a lot in the past three years about the answer.
Invest in Our Future’s creation marked a departure from philanthropy’s longstanding approach to climate and clean energy, which often focused on developing and passing policy to spur reductions in greenhouse gas pollution. Instead, with the Inflation Reduction Act on the books, my organization was formed with a singular focus: maximize the reach and impact of federal clean energy investments in the face of on-the-ground constraints.
Our remit was to ensure this ambitious policy advancing commercially-ready technology resulted in actual projects getting built and benefiting people. That meant mobilizing organizations to raise awareness of IRA programs and incentives and help communities access IRA dollars. It also meant finding a way around the significant barriers that stood in the way of deployment, even with historic levels of government support.
First, utility-scale projects were hit with organized, vocal opposition upset by the prospect of rapid changes to the local landscape and skeptical of out-of-town developers. That resistance often seized on siting and permitting processes to delay or altogether stop projects from being built. And too infrequently did countervailing forces try to speak to their concerns or organize support.
There were also funding problems for more community-oriented projects. In many cases, neither private investors nor public officials fully understood the opportunity or potential returns for projects like rooftop solar for schools, microgrids for hospitals and health centers, or electrified buses that double as mobile batteries during blackouts, leaving a sizable project pipeline struggling to pencil out.
Clean energy employers also struggled to hire, and workers couldn’t see a career path in the sector.
And as media habits changed, and national leaders spread disinformation, clean energy got more polarized.
For some, there was a political logic behind the IRA that suggested new projects would set off a self-reinforcing cycle of support for federal clean energy policy. But building support and real champions takes time. Consider that utility-scale solar projects, for example, need 24 months at minimum just to reach operational status. The work of connecting projects and benefits in the public mind extends further still. With barriers slowing deployment, the advantages of new projects needed time to take root.
Still, where projects did move forward, Invest in Our Future cultivated local validators who could share authentic stories about how clean energy improved their lives. When we mobilized local champions to engage with decisionmakers last year, they left a big impression. But we needed more of them — from more places, drawing value from more projects.
So after Congress repealed much of the IRA last summer, we developed new, interlocking strategies to address the major barriers to deployment and push as many projects forward in as many communities as possible.
By educating local decision-makers early and mobilizing active, vocal support from a wide range of perspectives — farmers and faith leaders, landowners and labor, educators and entrepreneurs — we can boost the number of projects that secure siting and permitting approvals.
By identifying high-potential, commercial-scale community projects with local lenders, packaging them into aggregated investments, and demonstrating low risk and reliable returns, we can draw institutional investors and lower-cost capital toward an otherwise underfunded but important segment.
Setting high and consistent job quality standards across clean energy industries will counter real and perceived concerns around safety, benefits, and wages, helping attract more workers who can go on to serve as advocates for new projects.
And deepening investment in storytelling by local champions will build the credibility of — and, in turn, support for — clean energy projects from the ground up.
Market forces are increasingly and irreversibly favoring clean energy. Influential allies of the president are coming around on solar, and longtime critics of renewables acknowledge that the transition is inevitable. What’s needed most now is a push from the ground up.
Our grantees are delivering it. Their work on siting and permitting, for example, helped gain approval for nearly 20 gigawatts of clean capacity in 2025. That included projects like Wisconsin’s Badger Hollow wind farm and Illinois’s 210-megawatt Glacier Moraine solar project — which was initially denied a permit but triumphed in a reconsideration vote after more than a dozen local residents mobilized to sway public opinion. Greenlight America and their partners managed to win eight permitting campaigns over one week last December alone.
Yet funding for these efforts is limited. Climate solutions receive less than 2% of total giving. Most funding within that segment has long flowed to regulatory and policy-focused work, which made sense while clean energy needed policy support to compete on economics. But today, with clean energy cheaper than fossil fuels in most parts of the country, there’s a real gap between our goals and on-the-ground success that we can bridge by focusing more on getting projects built.
Deploying clean energy at the community level happens to be one of our most effective tools for drawing down greenhouse gas pollution — with the added advantage of helping to lower costs, strengthen economic growth and community resilience, and generate good jobs. Through Invest in Our Future, I’ve met leaders driving progress often in the most challenging places in the country. Despite all the setbacks and discouraging headlines last year brought, these leaders have not lost their sense of urgency, or their resolve to build clean energy. That resolve — and their track record of success — should give us all hope. We should give them our support in return.
Current conditions: It’s pouring in Boston today, with temperatures that could feel as low as 47 degrees Fahrenheit • Severe flooding in Turkey’s Samsun province has sent a dozen people to the hospital • Bear season in Yellowstone has started earlier than usual, raising the risk of more violent encounters between hikers and grizzlies.
President Donald Trump formally began talks with Chinese president Xi Jinping today as the leaders of the world’s two largest economies seek some kind of rapprochement after more than a year of escalating battles over trade. The discussions are expected to cover a range of topics, including Taiwan’s sovereignty and the market dominance over critical minerals that Foreign Policy called Beijing’s “most potent” tool in the trade negotiations. Indeed, China’s control over critical minerals means Xi “will have the upperhand,” according to the Council on Foreign Relations, which noted that Trump folded last year in his trade battle with Xi once Beijing threatened to restrict flows of rare earths.
While Trump may have hoped that the prolonged closure of the Strait of Hormuz would put Beijing in a more desperate position by the time the summit started, China’s oil market has shown “signs of resilience” that “should concern U.S. officials” as efforts to prop up the domestic supply provide more buoyancy than expected, Semafor reported.
Fervo Energy, until now the hottest startup in the next-generation geothermal industry, is now the hottest stock on the market. On Wednesday, the Houston-based company’s stock began trading on the Nasdaq, where share prices surged nearly 40% by market close. “Geothermal is so hot right now,” Sarah Jewett, Fervo’s senior vice president of strategy, told me in a Q&A for Heatmap. “The IPO is not a finish line for Fervo. It is a financing milestone that facilitates the build out of more clean, firm, reliable, affordable energy. That is what we are most excited about as we ring the bell in Nasdaq. As we celebrate, we are more excited than anything to get back to work, to put clean megawatts in the grid.”
The company, she said, expects to start making overseas development deals soon, and indicated that Fervo may build its first geothermal plants on the East Coast, where hot rocks have historically been too deep to tap into, within a decade.
Nearly 16 years after it was first proposed, New York City’s biggest new source of clean energy has come online, meaning its 1,250 megawatts of capacity will be available to shore up the grid as summer heat waves roast the nation’s largest metropolis. Until recently, New York State regulators had planned for the Champlain Hudson Power Express to enter into service in August. But last weekend, the 339-mile project stretching from Lake Champlain down the Hudson River to the electrical substations in northwestern Queens managed to complete testing just before the state’s hard deadline of May 10 at 5 p.m. ET, after which the developer would have to wait two months before finishing the bureaucratic process to start the clock on the contract between the state and Hydro Quebec, the French-speaking Canadian province’s state-owned utility. That means if prices soar high enough between now and the end of May, Hydro Quebec could choose to bid into the market. But the real milestone is that, starting June 1, the utility’s contract will take effect.
“We didn’t think it was possible. The state didn’t think it was possible. We were counting on capacity coming online in August, but that’s way too late,” Peter Rose, the senior director of stakeholder relations for Hydro Quebec, told me on a call last night. “We have heat waves in July. It’ll be good for New York City to count on that 1,250 megawatts of capacity going into July.” Since the Blackstone-backed project’s inception, its proponents have suggested hydropower from Quebec would ultimately supply 20% of New York City’s power needs. But two weeks ago, when Hydro Quebec ran 13 hours of trial runs to stress test its equipment, the line provided more than 33% of the city’s power for a part of that duration. That, Rose cautioned, was probably due to relatively low load. Still, he said, “Unbeknownst to everybody during the testing regime, a third of our consumption in New York City was coming from this project. Those were specific conditions. But still pretty remarkable.”

Texas, newly-crowned the nation’s No. 1 solar market, has installed enough panels that the state is now generating more electricity from photovoltaics than coal for the first time. Solar generation is expected to reach 78 billion killowatt-hours in 2026 in the grid operated by the Electric Reliability Council of Texas, according to the latest forecast from the Energy Information Administration. That comes to just 60 billion kilowatt-hours for coal. As Texas’ solar boom continues, the federal researchers projected that about 40% of all solar installations in the U.S. this year will occur in the Lone Star State. Among the developments poised to come online this year is the solar and battery megaproject Tehuacana Creek 1 Solar farm. The 837-megawatt project will be the largest solar facility of its kind to enter into service this year. Meanwhile, Texas has no current plans for new coal plants.
The U.S. is going to need a lot more projects coming online. New forecasts from the National Electrical Manufacturers Association project U.S. electricity demand to surge 55% by 2050. Data centers are the biggest source of near-term demand growth, with a projected 300% surge in electricity demand over the next 10 years. But electric vehicles of all kinds are on track to keep the party going by spiking power demand 2,000% by the middle of the century. To meet that demand, storage, wind, and solar generation are on track to increase by 300% as renewables start making up a majority of the generation in the American West, New York, and the Southeast.
As I told you two weeks ago, Belgium is not only abandoning its plans to phase out its remaining nuclear power stations, it’s nationalizing the fleet. Now Brussels is entering into a deal with the pro-nuclear neighboring Netherlands to work together on building new reactors. The memorandum of understanding — signed Wednesday at a binational summit by Belgium’s energy minister Mathieu Bihet and Dutch climate and green growth chief Jo-Annes de Bat — establishes periodic meetings between the two nations, where the Netherlands can tap into Belgium’s existing knowledge from operating a larger fleet of reactors, and the Belgians can in turn garner tips on building new reactors as the Dutch embark on a construction program.
Pakistan’s solar boom has so far insulated the country from the full effects of losing access to oil and gas through the Strait of Hormuz. Now Islamabad is going all in. Pakistan is now targeting 95% renewable electricity by 2040, and 60% by 2030, according to a document seen by the business news site ProPakistani.
