Current conditions: The four-day Masters Tournament in Augusta, Georgia, is set to be the driest in 15 years, putting extra strain on the golf courses’ sprinkler systems • Severe Tropical Cyclone Maila is bearing down on Papua New Guinea and the Solomon Islands, deluging the autonomous island of Bougainville that is poised to vote to become an independent nation next year • A magnitude 6.2 earthquake just shook Indonesia’s Molucca Sea.

New Jersey just became the sixth state in the past decade to repeal its moratorium on building new nuclear reactors. The state enacted a de facto ban on atomic power construction in the 1970s, barring any permits for new plants until the federal government came up with a permanent solution for radioactive waste. But soaring electricity demand and a struggling buildout of offshore wind spurred Democratic Governor Mikie Sherrill to campaign last year on building at least a gigawatt of new nuclear capacity. On Wednesday, she signed legislation formally rescinding the waste requirement, authorizing the state to issue permits for new nuclear plants that, like all other atomic stations in the U.S., would temporarily store spent fuel waste on site in dry concrete casks. Speaking in front of a cooling tower at the Hope Creek nuclear generating station, one of two neighboring atomic plants in southwestern New Jersey that supply 40% of the state’s power, Sherrill said modern plants “are designed to be fail safe.” She added: “Across America, a nuclear renaissance is taking place.”
Five states — Wisconsin, Kentucky, Montana, West Virginia, and, as of January, Illinois — have fully repealed their statewide bans on nuclear reactors. While five of New England’s states maintain restrictions on atomic energy, all six endorsed a regionwide agreement to encourage construction of new reactors last month, as I previously reported. Virtually every state in that mix will face challenges building new reactors. The short of it, as Heatmap’s Matthew Zeitlin put it last year, is that “electricity markets aren’t working anymore.” The answer, at least for New York, is to rely on semi-socialist entities such as a state-owned utility to finance new reactors.
Hackers “affiliated” with Iran have been targeting programmable logic controllers, or PLCs, the crude industrial computers used to keep power grid operations going. That’s according to an advisory the U.S. Cybersecurity and Infrastructure Security Agency issued on Tuesday to the energy sector as the U.S.-Israeli war against Iran entered its sixth week, in spite of a fragile ceasefire deal. The North American Electric Reliability Corporation, the quasi-governmental grid watchdog, told Utility Dive it was “actively monitoring the grid.”
In Saudi Arabia, meanwhile, Iran attacked the country’s key east-west pipeline shipping oil to the Red Sea. A drone struck a pumping station on the 750-mile pipeline around 1 p.m. local time on Wednesday, the Financial Times reported.
BYD is officially on Brazil’s “dirty list.” The Ministry of Labor and Employment added the Chinese auto giant to its registry of employers that have subjected workers to conditions analogous to slavery after an inspection rescued 163 Chinese nationals at a construction site for the company’s new factory in Camaçari, in Bahia state. Auditors found fraud in migration papers and determined the factory was housing workers without mattresses and requiring shifts exceeding 10 hours without rest, according to a report by Folha de São Paulo. In one location, one bathroom served 31 people.
The company is set for a lot more scrutiny. BYD is among the top three Chinese automakers racing to set up dealerships in Canada after Prime Minister Mark Carney reduced tariffs, allowing Beijing to set up a beachhead on the continent despite harsh U.S. trade restrictions. Already, BYD has its eyes on 20 locations, as I previously wrote.

This is likely going to be the year deep sea mining becomes a thing. The obscure United Nations body in charge of figuring out global regulations for the industry has vowed to complete its task this summer. The Trump administration is charging ahead with plans to unilaterally establish permits for deep sea mining in international waters. Alongside smaller island nations such as the Cook Islands, Japan has been harvesting minerals from its own seafloor, as I wrote in February, and is now pledging to join Washington’s effort. All of that is good news for one of the biggest stocks in the sector, The Metals Company, a Canada-based but U.S.-backed startup racing to win the first American permits to extract mineral-rich nodules from the depths of the Pacific Ocean.
Now another company has entered the fray. American Ocean Minerals Corp. is merging with Odyssey Marine Exploration, which is already traded on the Nasdaq, in a reverse takeover that will create a roughly $1 billion deep sea mining company. The all-stock deal includes more than $150 million in private financing and $75 million in money American Ocean Minerals raised prior to the merger. Pending shareholder approval, the combined company will retain American Ocean Minerals’ name and trade under the ticker AOMC. “AOMC will be positioned to be a reliable, long-term supplier for American re-industrialization,” Tom Albanese, the former Rio Tinto chief executive now serving as the startup’s chairman, told Mining.com. “We are taking a differentiated, responsible approach to the research and development of deep-sea resources. The work over the past decade has set a high standard for advancing the industry responsibly, and we are proud to play a role in maintaining that standard.”
If you live in California, you’re one of the few Americans living in a market where a hydrogen-powered vehicle could work. But if you did make the switch to the less popular alternative to battery-powered cars, you aren’t faring much better than your neighbors driving gasoline guzzlers. The Iran War may be driving gas prices up past $7 per gallon in parts of the most populous state in the nation. But at least the gas stations are open. Just six of California’s 52 hydrogen refueling stations are currently in operation, according to data the trade group Hydrogen Fuel Cell Partnership shared with H2 View. “Several hydrogen stations are not available due to a disruption of the gaseous hydrogen supply chain that began in February 2026,” the trade group said. Five stations operated by Iwatani and Chevron are being supplied by low-pressure trailers, significantly reducing the amount of hydrogen they each receive. “You may not receive full fills during this time,” Hydrogen Fuel Cell Partnership said.
The planet is flickering. The longstanding assumption has held that the world is getting brighter with artificial light as illuminated neighborhoods blink into existence in growing Asian, African, and Latin American megacities around the world. But a new study in Nature shows that the planet’s brightness is going up and down year to year. As Heatmap’s Jeva Lange wrote: “Though the researchers confirmed a 34% overall increase in brightness during the study’s nine-year scope, it was offset by an 18% dimness, meaning the net increase in brightness was only 16%. Further, nearly half of the portions of land area that experienced at least one change in artificial light also experienced some form of abrupt change — that is, a brightening or dimming event that unfolded over weeks or months rather than years, such as grid failures in Venezuela, load-shedding in South Africa, changes to fossil fuel operations in Texas, and armed conflicts such as the war in Gaza.”

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.”
