Doug Burgum is, by all accounts, a normie. Compared to some of the other picks for incoming President Trump’s cabinet, the former North Dakota governor is well respected by his political colleagues; even many of the Democrats on the Energy and Natural Resources Committee seemed chummy with the former software executive during his hearing on Thursday, praising his support of the outdoor recreation economy and his conservation efforts in his state. As if to confirm the low stakes of the hearing, Burgum used his closing remarks not as a final pitch of his qualifications — but to invite his interrogators to a Fourth of July party at the Theodore Roosevelt Presidential Library.
That isn’t to say that the hearing doesn’t have consequences — or revelations about what can be expected from the all-but-certain-to-be-confirmed Interior secretary and future head of Trump’s National Energy Council. For many in the renewables space — particularly those in the wind industry — there was little in the way of reassurances that Burgum would temper his boss’ opposition to “windmills.” Additionally, the future Interior secretary dodged questions seeking reassurance about his commitment to protecting federal lands.
Below are some of the biggest takeaways from Thursday’s confirmation hearing.
Burgum referenced concerns about the “baseload” of the grid more than 15 times during the hearing, primarily as a way to oppose the buildout of renewable energy. “We’re short of electricity in this country, and we have to make sure that we have a balance,” he told Senator Catherine Cortez Masto, a Nevada Democrat, citing a standard Republican talking point about how the grid needs safeguards because “the sun doesn’t always shine and the wind doesn’t always blow.” When pressured about how intermittent energy sources are used in combination with storage, he added that we’re still “a few years out” from such technologies and warned that in the meantime, there would be “more and more brownouts and blackouts because we aren’t going to have the balance in the grid.”
“I don’t want the word ‘baseload’ to be code for no renewables,” Angus King, the Independent Senator from Maine, later followed up. Burgum protested against that characterization — “It’s not for any political reasons that I distinguish [between intermittent and baseload], it’s just because of the physics of the grid” — but King wasn’t satisfied. “In your case, in North Dakota, 35% of your electricity comes from wind power,” King said. “I presume that your grid works well?”
Burgum stumbled in his answer: “It’s super stressed, as it is around the country,” he said. (In fact, transmission bottlenecks seem to be the bigger issue in the state.) He went on to say that renewables plus storage equals a baseload at a “much higher cost” than traditional energy sources like oil and gas.
“It sounds like no more renewables,” King rejoined. “I don’t think that’s a sustainable path for this country, and it’s certainly not a way of meeting the challenge of climate change.”
One carbon-free source of electricity emerged as a winner of the baseload fight, however: nuclear power. “I’m glad to hear you talk about baseload,” Republican Senator James Risch of Idaho told Burgum, “because when you’re talking about nuclear, you’re talking about baseload.” Burgum also called solar and geothermal “big opportunities” in Utah.
Ahead of Thursday’s confirmation hearing, Danielle Murray, the founder of the Public Lands Center, issued a statement arguing that if Burgum did not “[reject] any and all attempts to sell-off or give away our nation’s public lands,” it would be “disqualifying.”
She and other public land advocates are not likely to be satisfied with the answers they heard, however. Burgum responded positively to an opening question from Republican Senator Mike Lee of Utah about restricting the size of National Monuments, noting that “a state like yours … already has over 60% of its land in public lands.” The Energy and Natural Resources Committee’s ranking member, Democratic Senator Martin Heinrich of New Mexico, followed up on that point, asking Burgum how he plans to “stay true to our conservation history” given the mounting attempts by Lee and his colleagues to “somehow, in a wholesale way, divest of our public lands.”
Burgum remained noncommittal: “I think there is certainly the opportunity for us to find that balance going forward,” he said again.
Burgum promised senators from Montana and Wyoming that he opposed a “blanket approach of trying to block” new coal development. “We have an opportunity to decarbonize, to produce clean coal, and with that produce reliable baseload for this country,” he said.
Why is that so important? “Without baseload, we’re going to lose the AI arms race to China,” Burgum said.
Wind was another hot topic during Burgum’s confirmation hearing. King pointed out that North Dakota is a major wind-producing state, and asked if the Interior nominee would talk to President Trump about “the fact that wind has its virtues and can contribute significantly” to America’s energy supply.
Burgum was resistant. If wind projects “make sense, and they’re already in law, then they’ll continue,” he allowed. “I think President Trump has been very clear in his statements that he’s concerned about the significant amount of tax incentives that have gone towards some forms of energy that have helped exacerbate this imbalance that we’re seeing right now.”
Risch celebrated Burgum’s skepticism of wind, rooting for the end of the Lava Ridge wind farm, which Heatmap’s Jael Holzman has reported Trump may kill on day one. “My good friend Senator King and I have different views on windmills — and bless you for taking the windmills, you can have them all,” Risch offered during his allotted time. “We don’t want them in Idaho. We hate windmills in Idaho.” (In 2023, wind accounted for about 15% of Idaho’s electricity generation.)
But if there was something Republicans on the Energy and Natural Resources Committee hated even more than wind, it was bears. Senator Daines of Montana specifically requested Burgum’s commitment to delisting grizzlies from the Endangered Species List, and he got what he was looking for. “I’m with you,” Burgum said. “We should be celebrating when species come off the endangered species list, as opposed to fighting every way we can to try to keep them on that list.”
Risch was also excited about this promise. “We don’t want grizzly bears [in Idaho],” he said. “They kill people. You know, the federal government already gave us wolves.”
Grizzlies weren’t the only bears on the chopping block. Republican Senator Lisa Murkowski of Alaska slammed the Biden administration’s Interior for not finishing its revised incidental take regulations for North Slope oil and gas activities — that is, the gas industry’s exemption to the Marine Mammal Protection Act of 1972 which otherwise prohibits the harassing, hunting, capturing, or killing of protected animals, including polar bears. “I need your commitment that you’ll work with Alaskans, particularly the Inupiat people up there, in the North Slope Borough, on basically all things polar bear,” Murkowski said.
“We’ll be happy to do that,” Burgum confirmed.

SoftBank’s error and Nvidia’s scandal suggest data centers may have already peaked as an economic and energy trend.
This is Heatmap Daily, a weekday digest written by our executive editor. Subscribe here.
Covering energy and climate change sometimes means seeing certain stories in a different light than others. And a particularly vivid hue illuminated The Wall Street Journal’s report today that the Japanese conglomerate SoftBank Group is taking a $3.7 billion loss on several gigawatts’ worth of natural gas turbines.
For the Journal, the big news is that SoftBank and its billionaire founder, Masayoshi Son, are failing to capitalize on the artificial intelligence boom. But at Heatmap, we’re thinking about the turbines.
The data center boom and the return of electricity load growth has depleted the world’s supply of natural gas turbines. SoftBank had purchased reservations for about 13 gigawatts of turbines, according to the Journal. That’s a staggering amount of electricity — it could meet New York City’s maximum power draw on the hottest part of a summer’s day. The conglomerate now seems set to dump reservations for about four gigawatts’ worth. Keeping a reservation, it turns out, really is harder than making it.
Most of those rotors were reportedly from GE Vernova, one of the world’s largest producers of gas turbines. GE Vernova’s order list for gas turbines has been filled for nearly two years and the waiting list now stretches into 2031. That has led data center developers, hungry to get power as soon as possible, to reach for ever dirtier forms of electricity generation, including diesel generators and even old jet engines.
On that front, SoftBank’s failure to sell the turbines to a higher bidder suggests (albeit weakly) that demand for energy-producing assets might not be as strong as the AI boom’s backers once thought. SoftBank was already set to send about 9 gigawatts of turbines to the enormous Trump-backed OpenAI data center in Pike County, Ohio. The roughly remaining four gigawatts will be released back their manufacturers. (One thing this news can’t quite tell us, alas, is what type of turbine set-up will be used in the Pike County facility, which will be the world’s largest gas-fired power plant if it is build to completion. Recent public filings have suggested the facility isn’t planning on using any turbines in the more efficient combined-cycle configuration, which would mean the plant’s carbon intensity will be worse than most other new natural gas plants. But we’d love to hear any tips on this front.)
To zoom out for a second, I’m struck by how the AI bubble has been replaced by an AI muddle. As I wrote this, news emerged that Nvidia is preparing to fire its CEO, Jensen Huang, for his affair with a Chinese woman who is alleged to be a spy. (He had at least one more affair with another Nvidia executive, according to The New York Times.) Under Huang’s leadership, Nvidia has invested in a sprawling and sometimes circular network of energy-related companies, including Emerald AI, a startup that helps data centers flex their electricity consumption, and Redwood Materials, a battery recycler and producer led by the former Tesla executive J.B. Straubel. Huang has used Nvidia’s enormous balance sheet to buy down the risk of other AI and AI-related companies, propelling the overall AI trade to become the biggest story in American markets.
Now that balance sheet is in peril: Nvidia’s stock is already down 11% over the past five days, and it has fallen another 8% in after-hours trading since news broke of Huang’s ouster. If the chip designer’s financial network began to fray — or even if the next CEO had a lower risk appetite than Huang — then its demise could impact a much larger set of firms.
Even before the Huang scandal broke, companies at the center of the AI trade were showing signs of weakness. Alphabet, Meta, and Microsoft are all down on the month. Nvidia was already lagging by about 10% on the month before its hebdomas horribilis began, too. The memory and chip makers Micron and Applied Materials are both down more than 25% in about the same period, and GE Vernova and Oklo have fallen nearly 20%. Although the data center company Coreweave rebounded on an earnings beat today, it’s still down 24% on the month and nearly 50% since May.
The market rout isn’t total — Anthropic seems likely to enjoy one of the largest IPOs ever in the next week (although perhaps not with quite as large a valuation as its investors once imagined). And the underlying technology of AI seems to be getting worryingly better all the time. But even though the politics of data centers and AI seem set to dominate the new Washington, I’m wondering if data centers as a mainstream economic trend might have already peaked. Americans voted for a more subdued AI boom in the midterms. Now it seems like they might get it ahead of schedule.
Lunar Energy’s latest AI-powered system aims to integrate EVs into the automated demand response mix.
In theory, it’s straightforward to assemble the smart energy home: Solar panels, home backup batteries, and electric vehicles, plus smart thermostats, heat pumps, and water heaters — all the individual pieces can be had for the homeowner who can afford the up-front cost. The challenge is getting all those pieces to talk to one another.
Bay Area-based Lunar Energy is one of the tech firms that’s been trying to crack this problem. Today, it announced an upgraded version of its artificial intelligence-powered home energy control system, which not only integrates all those separate systems but also responds tactically to energy markets. CEO Kunal Girotra told me Lunar AI saves its users money by monitoring their home 24/7 and making decisions to charge, not to charge, or discharge so that they save the most money.
“Utilities are all moving to almost-real-time changes of rates,” he said. “You need software to handle that for you. I think that the race is on for who has the best AI machine learning algorithms to save the most amount of money. And so far, we seem to have a head start.”
Lunar’s first-generation system focused on generation, storage, and control. In other words, it connected elements like a home’s rooftop solar panels with the backup battery the residents might keep in the garage, using the AI to decide when to meet the home’s real-time energy needs with solar versus grid energy versus stored power. What it didn’t have was the ability to work with electric vehicles to manage charging and use the car’s battery as a bonus source of energy.
To fix this, Lunar has built its own bidirectional EV charger — one that can charge up the battery or discharge the car’s battery for a secondary use, like backing up the home’s power supply. Girotra, formerly the head of Tesla Energy, told me the problem with that functionality to this point has been the connection point between the car and the home electrical system. Carmakers and other companies in the space didn’t have the deep experience with electrical certifications to make the process seamless, he tells me. That led to setups like the original Ford Charge Station Pro, which required several different wall-mounted electrical boxes to connect the F-150 Lightning EV to the home.
Lunar’s charger is built to connect to its customers’ existing home Lunar energy system, which includes a microgrid interconnect device they call Lunar Bridge that islands the home in case of a power outage on the grid. In that way, the power stored in the EV battery is ready to back up the home in case of a blackout without any additional work — or to be optimized as part of a fully smart home that’s making money as part of a virtual power plant.
The company’s setup allows for another fun feature: “slow” charging that’s not slow at all, but actually two or three times as fast as the Level 2 charging most EV owners use to recharge their batteries overnight. Electric cars in the U.S. can typically take on only about 11 kilowatts of AC power from one’s home because of the limitations of their on-board hardware. Because Lunar’s system is fully DC, however, Girotra said the company decided to build a DC home charger, one that — like a Tesla Supercharger or other DC fast chargers out in the world — isn’t limited by that power cap. Lunar said it could use a combination of power from the grid, home solar, or home batteries to charge an EV at up to 25 kilowatts. That’s enough to recharge an EV in three to four hours rather than six to eight.
“If the standards get high, and if everybody sees cars can get charged in three hours, then all of a sudden people are like, ‘Wow, this is how I want it,’” he said. “Especially for 25% of the users who are like me, who always are running low on charge and they don’t mind a boost every now and then.”
Some of the other improvements in the second-gen system are more incremental. An inverter that’s 40% more powerful helps Lunar get its system up to enterprise scale. That’s crucial, as the world moves toward a place where more homes and businesses employ battery backup systems. Lunar’s new batteries come in modular 5 kilowatt-hour blocks ranging from 10 kilowatt-hours to 30 kilowatt-hours in a single unit and scale up to 300 kilowatt-hours for home or small commercial use; there’s also new pad-mounted configurations with capacity up to 1 megawatt-hour.
Batteries, though, are the simple part. Everyone from EV makers like Rivian to utilities like Octopus Energy is racing to make a person’s or a business’s batteries and solar panels and electric cars work for them, using the power of AI to account for moment-to-moment changes in energy prices and supply. Lunar’s new tech makes the case that the most important element is a single brain to integrate every last smart, electrified thing in your house.
The fundraise comes on the heels of a $50 million grant from the Department of Energy.
Almost all lithium-ion batteries on the market rely on graphite for their anodes, more than 90% of which is processed in China. That concentration has created a chokepoint in the Pentagon’s supply chain as the military increasingly turns to batteries to help its transportation network operate more quietly and reduce reliance on complex refueling logistics.
So when Congress passed the latest National Defense Authorization Act at the end of 2025, barring Chinese-linked battery materials from military use starting in 2028, Coreshell saw an opening. While the California-based silicon-anode battery startup had previously focused on automakers as its beachhead customers, it’s now shipping its first battery cells to the military for use on Navy ships and Army ground vehicles. On Wednesday, Coreshell announced a $30 million Series B to scale up manufacturing operations to meet the needs of this growing customer base.
“We’re entering a new stage where we’re no longer, I would say, demand limited,” Coreshell’s CEO Jonathan Tan told me. “This year we’ve had to put on second and third shifts, work nights and weekends, just to get the product out the door.”
Coreshell sets itself apart by going a step further than the NDAA requires. The law doesn’t make suppliers trace battery materials all the way back to the mine, which would be exceedingly difficult given China’s dominance across the battery supply chain. But Coreshell has nevertheless eliminated Chinese sourcing from its anodes by replacing graphite with silicon mined and refined in the U.S. by Ferroglobe, one of its Series A investors.
Ferroglobe and global investment firm Access Industries led the latest round, with defense contractor ADS also joining as a new strategic investor. The financing comes on the heels of a $50 million Department of Energy grant that Coreshell secured in August as part of a program to strengthen the domestic battery supply chain. That funding will support the company’s first commercial-scale facility, a 2-gigawatt-hour factory.
That’s about 20 times the size of the 100-ish-megawatt-hour plant the startup had originally envisioned, as the DOE grant has allowed Coreshell to “expand much further than we were originally expecting,” according to Tan. The company is now evaluating several potential U.S. sites and expects to announce its selection early next year. For now, it relies on unnamed contract manufactures, along with its small pilot line in San Leandro, to produce its cells. But once the gigafactory gets up and running, the startup plans to bring electrode production in house by 2028, followed by full cell assembly in 2029.
Building this plant will ultimately require significant additional capital. But Tan believes this latest vote of confidence from the federal government will help Coreshell to diversify its capital stack as it continues to fundraise. “That’s one of the great things about having such a notable DOE award is that it also allows us to attract multiple forms of capital,” he told me.
Silicon has long been recognized as a promising alternative material for battery anodes, as it can store far more energy than graphite. The catch is that it tends to swell during charging, causing it to break down quickly and ultimately leading to a much shorter cycle life. Coreshell says it’s extended its anode’s lifespan by giving it a proprietary coating, which Tan told me back in April essentially means “painting the inside of your battery” with an ultra-thin protective layer.
Other companies, such as Sila Nanotechnologies and Group14 Technologies, are also working to commercialize silicon anodes. But Coreshell says many of its competitors rely on more highly engineered, expensive forms of silicon, such as silane gas. By contrast, Coreshell uses metallurgical silicon, a cheap, raw commodity already widely used in aluminum alloys. That, Tan argues, gives the company a cost advantage not only over its competitors, but potentially Chinese graphite too.
Coreshell hasn’t yet demonstrated that its cells can meet the performance demands of the automotive industry, however. When the company raised its Series A in early 2025, it said it expected its automotive cells to exceed 1,000 charge cycles while retaining 80% of their original capacity. But Tan told me many defense applications don’t require such demanding performance targets, as Navy ships and ground vehicles are “not intending to have as many miles or missions or use cases on that same battery” as a consumer EV would.
That doesn’t mean the company is abandoning its automotive ambitions. As Tan pointed out, electric vehicles remain by far the largest source of global and domestic battery demand. “It’s natural for us to obviously utilize the security supply chain first,” he told me. “That allowed us to really get to commercialization, revenue, and production faster, because automotive qualification is this longer journey. But ultimately, we want to do both of those and more.”
