On the transformer shortage, sodium batteries, and a space grid

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.

Quiet desperation, meet artificial intelligence.
Like many new parents, I devote considerable time to thinking about sleep and why it’s not happening. Should I have sung the bedtime song and then changed the diaper? Did the baby need a fourth nap, or was the mistake letting her take a third so close to bedtime? It came as a surprise the other day, then, when a fellow parent in my baby group revealed she isn’t overthinking the whole sleep schedule thing at all. “I asked ChatGPT to write my baby’s sleep plan,” she told us. “It’s validating!”
To this author, personally, outsourcing parenting decisions to the world’s most sophisticated Mad Libs respondent seems like one of the signs that we’re doomed. Sleepmaxxing mothers aside, a plurality of Americans agree with me. Per Heatmap Pro’s latest polling, 45% of voters are “pessimistic” about the long-term impact of artificial intelligence on their lives, with just 22% saying they’re “optimistic” and about a third saying they’re unsure.
Americans were even more negative about the perceived impacts of AI on “society as a whole” — more than half, 55%, said they were pessimistic, while just 17% said they were optimistic. Maybe “future generations” will have it better? Eh. Again, net pessimism outweighed optimism in our polling by more than 30 points (52% to 20%).
Look a little closer at who hates their life because of AI and you might be surprised. The youngest respondents in the survey (and those who will have to live with the tech the longest), were by far the biggest doubters. Respondents aged 18 to 34 reported the most pessimism of any major demographic about the estimated impact of AI on their personal lives, tied with women generally at net 33 pessimistic over optimistic. For AI’s impact on society as a whole, there was a 53-point spread in favor of AI making things worse (68% pessimistic to 15% optimistic), which is 15 points worse than the next most pessimistic age group, the 35- to 49-year-olds.
Seniors, by contrast, are a little more sanguine. Among the 65-and-over crowd, the pessimism gap was a comparatively small net 12. In fact, men over the age of 65 were the only major group to report being more optimistic than pessimistic on AI’s impacts on future generations (34% to 30%) and on their own lives (35% to 32%). By contrast, young women were among the most negative of all groups; nearly three in four women in the 18 to 34 range (73%) said they were pessimistic about AI’s impact on society, and the same group was net 62 under water on AI’s effects on future generations. (Our findings are in keeping with other polls that show a gender gap on the embrace of AI.)
Education, surprisingly, wasn’t a big difference-maker. People who attended college reported nearly identical pessimism about AI’s impacts on society and future generations as non-college-educated respondents. College-educated people were just a few points less pessimistic about AI’s impact on their own lives, 25% versus 29% for those who didn’t attend.
So who actually thinks AI is going to be a good thing? Black respondents were at least more evenly divided on the impact of AI on their personal lives (33% optimistic to 33% pessimistic), though they were less convinced that the technology is good for society or future generations (13 points net pessimistic). People who prefer a hands-off federal approach to AI are generally encouraged by the technology’s application in their own lives, at net 13 optimistic. But even the most AI-friendly group’s outlook dropped off when considering its implications on society as a whole (net 4 pessimistic) and on future generations (net zero).
Independent voters bristled more at AI’s impacts on their lives (pessimism net 32) than Democrats (net 30), and on the question of “society as a whole,” the bloc ran away with net pessimism of 48, compared to Democrats (net 45) and Republicans (net 27). Among Republicans, MAGA voters were net 25 toward pessimism about AI’s impacts on their lives — in spite of President Trump’s boosterism — compared with the even-more-pessimistic non-MAGA voters at net 34 pessimistic.
Are Americans just a half-glass-empty group to begin with? Well, maybe — the percentage of adults who told Gallup they anticipate having “high-quality lives in five years” declined to less than 60% in 2025, the lowest level in two decades of polling. And while this is Heatmap’s first year tracking AI optimism, in Stanford University’s 2025 Artificial Intelligence Index Report, an adjacent line of inquiry found that people are increasingly warming up to the technology, with the “share of individuals who see AI products and services as more beneficial than harmful [rising] from 52% in 2022 to 55% in 2024.”
At the same time, about a third of Americans in our polling worried that AI puts their jobs at risk; a mere 6% said they believe that “AI will create jobs across the country, and I expect my own career to benefit.” Hopefully, there are no baby sleep trainers among their numbers.
The Heatmap Pro poll of 4,118 American registered voters was conducted by Embold Research via text-to-web responses from May 15 to 28, 2026. The survey included interviews with Americans in all 50 states and Washington, D.C. The margin of sampling error is plus or minus 1.6 percentage points.
Current conditions: The southwest monsoon known as “hagabat” has started in the Philippines, dumping up to 4 inches of rain on the archipelago • A strong geomagnetic storm, ranked just two levels below the most powerful type of event of this kind, is underway, threatening radio signals, GPS, and other human instruments that are sensitive to shifts in the Earth’s magnetic fields • San Antonio, where the glorious New York Knicks defeated the Spurs last night, is bracing for rain through the weekend.
To put it in terms a movie lover could understand, President Donald Trump’s Iran War is drinking the U.S. government’s milkshake. Federal stocks of oil have dropped to their lowest level since 2004. Commercial crude stocks fell by 8 million barrels to 433.7 million last week, according to The Wall Street Journal. Unless the Strait of Hormuz reopens soon — which looks less likely now that Iran has called off negotiations with the U.S. and Israel — prices could hit $200 per barrel by summer, said Bob McNally, president of the Rapidan Energy Group consultancy and a former White House adviser. “You start to raise the risk of spillover into other sectors, the economy and financial system … it detonates fragilities in the broader economy and financial system,” he told the Financial Times.
Oklahoma Attorney General Gentner Drummond has filed a lawsuit to block construction of the United States’ first new aluminum smelter in half a century over concerns about the project’s ties to the United Arab Emirates and risks it poses to the state’s cattle industry. Century Aluminum had planned to build the smelter with $500 million from the Biden administration. But in January, as I told you at the time, the company overhauled the deal to partner instead with the Abu Dhabi-based Emirates Global Aluminum, which said it became interested in the project after Trump slapped 50% tariffs on the metal. The move comes after Trump endorsed Drummond’s opponent in this year’s Republican primary for Oklahoma governor.
In the 12-page litigation, the state’s top cop alleged that the smelter, planned for a site 30 miles east of Tulsa, would “leach air and water pollutants that would injure the health, comfort, repose, and safety of the people in the region,” Mining.com reported. “A primary aluminum smelter does not belong in a community’s backyard and its emissions do not respect property lines,” Drummond wrote in the lawsuit, which asks the court to block the project. His lawsuit also refers to the UAE, a close ally of the U.S. and by far the most liberal of the Gulf Arab kingdoms, as an “Islamic foreign monarchy.”
The Electric Reliability Council of Texas, the state’s grid operator, approved what E&E News called two “landmark sets of rules of rules” this week that would “shape the future of data centers in the state if finalized.” One package sets up new criteria and processes for bringing big electricity users onto the grid by reviewing them in batches. The other requires data centers and crypto mining operations to remain online during brief grid disruptions in a bid to avoid the cascading outages that downed the electrical system during 2021’s deadly Winter Storm Uri.
The changes come as opposition to data centers reaches critical new heights. Seven in 10 Americans now oppose server facilities built near their homes, according to a new Heatmap Pro released a poll this week that my colleague Robinson Meyer wrote up here. The backlash has grown so severe that former Representative Ben McAdams, a Republican from Utah, is facing serious pushback from his Democratic opponent for the state’s new 1st Congressional District over his small stake in the renewable energy component of a proposed data center in the area, according to the Salt Lake Tribune.

Taiwan, if you’ll forgive the pun, is in dire straits. The self-governing republic that has functioned as an independent country since the losing side of the Chinese Civil War fled there in 1949, is almost entirely reliant on imported fossil fuels to keep the lights on and semiconductor fabricators churning out the hardware that makes the island so valuable to the global economy. That reliance only grew last year when the ruling Democratic Progressive Party, which has opposed atomic energy since its founding in the 1980s, completed the country’s nuclear phaseout, shutting the last of the island’s three functioning plants. The government in Taipei is now considering starting back up at least one of the old nuclear plants. But, as I told you earlier this year, it’s also looking to geothermal to make up the difference. On Wednesday, the Ministry of Economic Affairs announced the first government-led tender for geothermal, Think Geoenergy reported. The six-month process is meant to develop geothermal zones in Taitung County, on the island’s southeast coast.
The Iran War isn’t just draining America’s crude stockpiles. It’s also spiking gas prices — and spurring a hybrid boom. Sales of hybrid vehicles revved 33% in May compared to the same month last year, according to a Wall Street Journal analysis of Motor Intelligence data. “The hybrids have been a godsend,” Mark Politte, the dealer principal at Stanley Subaru in Ellsworth, Maine, told the newspaper. They are “hotter than the non-hybrids.” While new vehicle sales are down 4.4% overall this year through May, hybrid sales are up 17% compared with 2025.
Meanwhile, autonomous electric vehicle company Waymo announced a deal on Thursday to recycle batteries from its nearly 4,000 operating robotaxis into battery storage for electric grids in California and Texas. Waymo’s fleet is made up mostly of Jaguar I-Pace EVs, which have 90-kilowatt-hour batteries. “Put a little haircut on that in terms of degradation and the effective capacity that would be left in those batteries when they’re suitable for repurposing, and we’re still talking about pretty significant capacity per battery,” Freeman Hall, CEO of B2U Storage Solutions, Waymo’s partner in the project, told Ars Technica.

The U.S. may be depleting its oil stockpiles, but it has increased its storage capacity for natural gas in the future. Underground storage capacity in the Lower 48 states increased slightly in 2025, growing mostly in the South Central and Mountain West regions, according to new data from the Energy Information Administration. “Underground natural gas storage provides a source of energy when demand increases, balancing U.S. energy needs,” analyst Jose Villar wrote. “We calculate natural gas storage capacity in two ways: demonstrated peak capacity and working gas design capacity. Both increased in 2025.”
Notes from Heatmap’s second Energy Entrepreneurship Summit.
I’m writing from Washington, D.C., today, after having the privilege of watching (and moderating) Heatmap’s second Energy Entrepreneurship Summit this morning. We heard from folks leading in a variety of technologies — geothermal, batteries, fusion, conventional nuclear — but I was struck by a few common themes.
The first was the new wave of excitement about fusion energy and how, in some ways, the artificial intelligence boom has reinvigorated the fusion conversation. Much like fusion, AI was a long-prophesied technology that made steady, iterative improvements over time — and then, one day, delivered a transformative product in the form of ChatGPT. I’m not sure if fusion has yet had a raw technological improvement on par with the transformer, the neural network innovation that preceded today’s AI chatbots and agents, but fusion startups have reported significant improvements in recent years. The industry believes — as do some fusion-pilled policymakers — that they will have commercial reactors on the grid by the mid-2030s.
The second is the degree to which surging electricity demand is pushing forward clean energy across the board. Although many (but not all) hyperscalers prefer to buy clean energy, the raw demand for power is fueling confidence among energy developers and technologists of all stripes. It’s great to make a commodity whose price is rising. At some point, this link between AI and electricity may become turbulent for developers — but we’re not there yet.
The final note is the degree to which U.S.-China competition now dominates conversations around the energy industry and the economy more broadly. I can remember a time when it was somewhat peculiar to point out that some forms of energy prowess strengthened the country’s national security — and that if the U.S. did not work those muscles, then China would. There was little overlap between the clean energy and security conversations. Now, the rise of globally competitive Chinese “electrotech” firms such as BYD, Xiaomi, and CATL has almost united the two discourses.
There is a growing recognition, too, that America will have to reindustrialize to compete. Policymakers sometimes talk about how the U.S. should use its (for now) still strong R&D apparatus to develop “leapfrog” technologies that can surpass Chinese products. But as America has by now repeatedly discovered, simply inventing a new technology is not enough. Creating an export industry — not to mention a business — actually requires commercializing that technology and scaling it. And that will entail the rudiments of an advanced industrial economy: more hardware factories, a larger grid, more manufacturing and process engineers.
These concerns over basic competitiveness colored discussions of even the most advanced technologies. Jackie Siebens, a vice president at the fusion startup Helion, said she was worried that fusion is going to “follow a story we’ve seen before,” where the United States demonstrates fusion first, “but China scales much more broadly.” Representative Don Beyer, a Democrat from Virginia who champions fusion, brought up a more fundamental concern: China is graduating hundreds of nuclear PhD engineers every year, he said, while America is only graduating a few dozen.
If affordability makes up one half of our new energy era, then these questions around competitiveness might be the other half. We’ll explore them, I’m sure, in the future. For now, thanks, as always, for reading.
