On depleted U.S. oil stocks, Taiwan geothermal, and hybrid sales

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.”

Current conditions: France just recorded its hottest day ever, with Wednesday’s temperatures soaring to just under 111 degrees Fahrenheit; nearly 50 people died drowning while seeking respite from the heat • A pair of 7.1-magnitude earthquakes struck Venezuela, collapsing buildings in Caracas • Wind has whipped the Cottonwood Fire, one of six wildfires raging in Utah, into a larger blaze now covering 60,000 acres — and it’s still at 0% containment.
New Jersey Representative Frank Pallone, the ranking Democrat on the House Energy and Commerce committee, joined calls for a national moratorium on data center construction ahead of Wednesday afternoon’s markup of a series of bills related to the buildout of infrastructure to support artificial intelligence software. In a statement, Pallone described the bills as a “useful first step,” but one that, “compared to the challenges the American power grid is facing,” amounts to “not nearly enough.” Rather, he backed a “national AI data center moratorium until we can find a way to ensure they don’t harm our nation’s air, water, and power bills.” Pallone’s new public position makes him one of the highest-ranking Democrats yet to back the idea, championed by the likes of Representative Alexandria Ocasio-Cortez, of halting permitting on new data centers in response to the growing blowback from voters.
Pallone’s shift comes in response to the Ratepayer Protection Act, which would enshrine into law the voluntary pledge tech companies signed with the White House to pay for grid costs from their server farms. Heatmap’s Matthew Zeitlin wrote earlier this week that the bill was “not so much an anti-artificial intelligence or anti-data center bill, but rather a move to insulate further data center development from political pressure stemming from rising electricity costs.” When Pallone made his statement a day later, Matthew wrote: “Well, at least one influential lawmaker seems to agree with me.”
The Iran War has cost the average American car owner an extra $156 and the average SUV driver another $232 in gasoline costs, according to new data from the policy shop Third Way. But the newly mapped analysis, shared exclusively with me, shows that Republican-leaning states in the Mountain West and beyond paid some of the highest prices for a conflict. Alaska saw one of the biggest spikes, with gas prices rising by $1.40 per gallon, a 39% increase. Wyoming followed close behind, with prices soaring by $1.37 per gallon, a 50% surge. Prices in Utah, meanwhile, climbed by $1.30, or 47%. That stands in contrast to many big Democratic-leaning states. New York’s gas prices rose by $1.23, or 41%, while California’s prices went up $0.94, or 20%. That, of course, doesn’t reflect where the prices were already high. I just returned this week from a trip to Los Angeles, where gas was nearly twice as expensive as in New York City.
Century Aluminum, America’s largest primary aluminum producer and the developer behind the first new U.S. smelter in 50 years, has inked a deal with a green cement startup to supply a key raw material. Brimstone, known as a major player in the race to commercialize green cement, also generates alumina. On Wednesday, the startup unveiled a memorandum of understanding with Century Aluminum to establish a domestic “mine to metal supply chain” for aluminum made from scratch rather than scrap. “Foreign sources, including China, currently dominate global alumina production. Brimstone is bringing alumina production home and doing it at a globally competitive price,” Brimstone CEO Cody Finke said in a press release. “Brimstone is upending the massive global imbalance by producing alumina from rock quarried here in the United States.”

Until the nation’s flagship reactor project came online and transformed Southern Company’s Alvin W. Vogtle Generating Station in eastern Georgia into America’s most powerful atomic electrical plant, Arizona’s Palo Verde Generating Station was the No.1 nuclear facility by size in the country. The desert state is now looking to reclaim its mantle. The trio of utilities Arizona Public Service, Salt River Project, and Tucson Electric Power said Wednesday they are continuing “to work together to explore adding nuclear generation in Arizona.” The next step, the companies said, is a siting study that’s expected to be completed within the next six months. The Arizona Corporation Commission, the regulator in charge of utilities in the state, is holding an informational workshop today.
Meanwhile, the developer behind Canada’s flagship reactor design — which, because it’s cooled with pressurized heavy water, can run on raw uranium — just submitted initial paperwork to the Nuclear Regulatory Commission to start the licensing process to approve what’s known as the CANDU. Pronounced CAN-do and produced by manufacturer AtkinsRéalis, the reactor is the workhorse of the Canadian and Indian fleets and can be built reliably, but requires more maintenance than the light water reactors that run on enriched uranium and make up the entire U.S. fleet. “As the United States enters a new chapter in its civilian nuclear program, AtkinsRéalis is uniquely positioned, as the steward of CANDU technology, to help advance the country’s ambitious energy policy through proven, low-cost reactor technology with a world-class reputation,” Ian L. Edwards, the company’s president and chief executive, said in a statement. As I told you last month, the CANDU is at the heart of Canada’s new nuclear strategy.

The world needs a lot more copper. And while siting and building new mines takes time, two of the planet’s biggest producers are preparing to increase production at existing mines. On Wednesday, London-based Anglo American and the Chilean state-owned Codelco inked a deal to increase production through a joint venture at Los Bronces and Andina copper mines in the South American nation. The joint mining plan is expected to unlock 2.7 million metric tons of additional copper over a 21-year period, delivering an average of 12,000 tons per year. The increase comes with “minimal capital investment” and should bring the new supply online by 2030. “This agreement represents a more efficient and responsible way to develop one of the world’s leading copper districts,” Bernardo Fontaine, Codelco’s chairman, said in a statement. “It allows us to make better use of existing infrastructure, capture greater benefits for Chile, and move forward with a long-term vision based on operational excellence, sustainability, and the responsible use of resources.”
If green hydrogen is the stuff made with clean electricity and water and blue hydrogen is made with natural gas equipped with carbon capture, then the orange stuff is found in underground rock formations where naturally occurring gas forms and then is encouraged to continue forming through artificial means. Heatmap’s Katie Brigham did a good job of explaining the concept here. Well, now a French renewables developer FDE is promising to start producing orange hydrogen “by late 2028 or early 2029” after finding a naturally-occurring underground reservoir in northern France that can be tapped and stimulated to produce additional fuel, Hydrogen Insight reported.
How China saved the world from $200 oil.
Turn your mind back to early March, soon after Iran announced that it was closing the Strait of Hormuz. Energy experts told us to expect calamity.
Roughly 20% of the world’s oil and liquified natural gas supply moved through the narrow waterway, they said, and we would not soon be able to replace it. Oil prices would rocket to $150 or $200 a barrel. The world faced the worst energy supply shock in history.
We braced ourselves. We waited. And then … it didn’t happen.
Sure, the global oil benchmark rose to about $115 a barrel. Energy prices increased everywhere, and Southeast Asia faced a real crunch. But the worst consequences never hit. Europe didn’t run out of jet fuel, we didn’t get $8 gas across the United States, and the global economy did not shut down. Why?
We can now say with confidence: China bailed us out (and itself out, too). Without fanfare, the country slashed its energy imports and conducted a massive release from its strategic stockpiles of crude oil and liquid fuels. It eliminated something like 5 million daily barrels of oil demand, or about 5% of global oil demand.
Although it might seem technical, the implications of that silent intervention are huge for geopolitics, climate policy, and the future of the oil market. That’s why it’s the topic of today’s episode of Shift Key, Heatmap’s podcast. I encourage you to listen to my conversation with oil analyst Rory Johnston as he walks me through the wonky details — how we know China did this (math and satellite imagery), whether it has a modern precedent (it doesn’t), and what it all means (potentially a lot). He calls this public discovery of China’s latent power “the most important thing” we learned from the Iran war.
Anyway, I won’t ruin the conversation. (You can listen to Shift Key for free on any podcast platform, by the way.) But I do want to mull some of the implications here. The most important, to my mind, has to do with market power.

In oil markets, we often talk about “swing producers.” Saudi Arabia and other OPEC+ countries can shift the global oil price not just because they oversee a large share of the world’s oil production, but also because they can flex domestic production at will. They can increase or decrease their own output to affect the global marginal barrel’s price, stabilizing prices (or hiking them) as needed. (This originates partly from geological luck; Saudi Arabia’s reserves seem particularly well suited to rapid ramp-ups or ramp-downs in drilling and pumping.)
That suggests a mirrored role: a “swing consumer.” What if a country had such large oil stockpiles that it could ramp up or ramp down its imports at will, such that it could move global demand for oil at the margin? Such a thing has never existed in the history of the global oil market, at least to my knowledge. America has experimented with mini-versions of this idea in the past; the Biden administration released oil from the Strategic Petroleum Reserve in 2022 to depress prices after Russia invaded Ukraine. Outside of oil, China already plays a similar role in many global mineral markets, single-handedly shifting global prices for iron, lithium, copper, and other commodities.
But China's actions over the past few months suggest that its domestic oil stockpiles might now be so big that the country can play a swing role in global liquid fuels markets. After President Trump announced that he had reached a deal with Iran, I reflected in this newsletter on the fact that the world now had two energy systems, at least in the transport sector: a legacy liquid fuels system and a rival electricity system. These systems’ supply is divided among the world’s powers. The U.S. is the largest oil and gas producer in the world, but China is the largest manufacturer of solar panels, EVs, and batteries.
Yet if China is also now the world's swing consumer of oil, it suggests the country now has much more influence over the world’s most critical energy inputs in any form — fossil, electric, or mineral — than we had once thought. That isn’t my only Heatmap-relevant takeaway from the Iran war. But it is one I suspect we will remember for years to come.
New Jersey’s Frank Pallone, ranking member on the House Energy and Commerce Committee, says “this simply cannot continue.”
It was just yesterday that I wrote about the Ratepayer Protection Act, a bill that would transform into law the voluntary pledge big tech companies signed with the White House to take on additional electric grid costs from their data centers. My argument was that it’s not so much an anti-artificial intelligence or anti-data center bill, but rather a move to insulate further data center development from political pressure stemming from rising electricity costs.
Well, at least one influential lawmaker seems to agree with me. The Democratic ranking member of the House Energy and Commerce Committee, New Jersey Representative Frank Pallone, called for a national data center moratorium before the Wednesday afternoon markup of a series of data center-related bills, the Ratepayer Protection Act among them.
Pallone described the proposals being discussed at the markup as a “useful first step,” but that “compared to the challenges the American power grid is facing, they are not nearly enough.” Instead, he called for “a national AI data center moratorium until we can find a way to ensure they don't harm our nation's air, water, and power bills.”
Pallone cited a slew of efforts in his home state to slow the rapid proliferation of data centers, including a resolution in Asbury Park calling for a statewide moratorium and the city of New Brunswick rejecting a planned data center project earlier this year.
“This simply cannot continue,” Pallone said of the pace of data center development. (When asked for comment, Pallone’s office pointed to his prepared remarks.)
Pallone is not the first Democrat to call for a data center moratorium, but he’s the moratorium supporter who is most closely involved in energy policy at the national level. Senator Bernie Sanders and Representative Alexandria Ocasio-Cortez, two of Congress’ most prominent progressive Democrats, have called for a nationwide moratorium, sponsoring a bill that would enact “a reasonable pause to the development of AI to ensure the safety of humanity,” including a halt to data center construction until a laundry list of conditions were met related to both energy prices and AI safeguards.
The Democrat-controlled New York State legislature also passed a one-year data center moratorium earlier this month, although the bill is still sitting on the desk of Governor Kathy Hochul, a Democrat, awaiting her signature or veto.
Politicians calling for moratoria are trying to catch up with a public that has quickly soured on data centers. A majority of the American public supports a nationwide moratorium, according to polling done by Heatmap, with 40% of respondents giving the idea their strong support.
One reason why Americans increasingly oppose data centers is that they blame the developments for inflating their electricity bills. When Heatmap polled this question last August, 28% of respondents blamed “the construction of new data centers” for rising electricity prices. When we asked again last month, 53% did.
Analysts have looked at electricity price increases in the past five to 10 years and found little consistent relationship with data center construction, though that is not necessarily true everywhere and at all times.
In New Jersey, which is part of the PJM Interconnection electricity market, prices have likely risen based on current and planned data center construction within a grid area that has long had trouble bringing on new generation or building out sufficient transmission. PJM’s independent market monitor has attributed $23 billion in added costs to “existing and forecast data center load” in the system’s capacity auctions.
New Jersey Governor Mikie Sherrill implemented a rate freeze almost immediately following her inauguration earlier this year after years of price hikes and rising bills. Average electricity bills in the state have risen from around $91 per month to $140 per month, according to the Heatmap-MIT Electricity Price Hub, while electricity prices have risen almost 52% in the past five years.
Pallone was skeptical that any intermediate steps have or could work to protect ratepayers.
“Promises by the data center industry and Big Tech that these facilities will bring down costs have fallen flat,” Pallone said at Wednesday’s markup. The Federal Energy Regulatory Commission’s efforts to prompt regional electricity markets to overhaul their interconnection policies “may have promise, but it will take months, if not years, to come to fruition,” he said. The Ratepayer Protection Pledge, meanwhile, has “no enforcement,” and constitutes a “toothless promise from Big Tech.”
“Americans across the country have expressed concern and opposition to the rampant construction of AI data centers, and Congress should take this political groundswell seriously with a data center moratorium,” Pallone concluded. “That's what we need.”
