The whales will be fine.

Donald Trump loves eagles and whales and therefore he wants to protect them — from clean energy development.
Trump may, however, be relieved to hear that many of his concerns about wind and solar energy are unfounded. Here’s what he gets right and wrong.
Pointing out the window to the Atlantic Ocean at one point, one attendee said, the former president claimed that offshore wind turbines break down when they are exposed to saltwater … [April 17, 2024]
Fact check: Let’s just get this out of the way: offshore wind turbines are designed to withstand saltwater exposure. People have been building things in saltwater for a long, long time. From the oldest known ships constructed 6,000 years ago out of papyrus reeds to Norway’s Troll A platform — a reinforced concrete offshore natural gas platform and the tallest structure ever moved by humankind — we’ve learned a few things about resisting salt corrosion.
This scene occurred during a fundraising dinner with oil and gas executives at Trump’s Mar-a-Lago resort reported on by The Washington Post, which also pointed out this obvious fact. That said, to the former president’s credit, “the ocean is indeed a difficult environment” for construction and engineering, Eric Hines, a civil and environmental engineering professor and the director of the offshore wind energy graduate program at Tufts University, told me. But the lifespan of offshore structures can range from a few years to more than a century.
According to Hines, most offshore wind farms today are built to have “approximately 25-year service lives,” but the design is always evolving. His department, for example, is working on developing advanced underwater foundations that are built to last more than a century and double as artificial reefs.
“I like the concept of solar, but it’s not powerful like what we need to fire up our factories.” [Dec. 16, 2023]
Fact check: “That question is actually a little bit tricky,” Baker, the assistant professor of engineering at the University of Colorado, told me, when I asked him whether solar alone could power a factory — but it’s also not really what we should be asking. “One thing I’ve noticed people do a lot is they’ll just compare efficiency of power generation,” Baker explained. But “it’s not just about the efficiency — it’s about other things, too, like solar’s ability to be distributed. You can’t put a nuclear fission power plant in your house — you know, not yet — but you can put solar panels, so that’s a huge benefit. It offers some resiliency that other sources just can’t offer.”
It’s true that solar power is less efficient than other sources of energy, including wind, and that it requires a lot of surface area, which could be an undue burden for a manufacturer. But at the same time, “I don’t know if anybody is proposing to power an entire factory based off of solar,” Baker said.“Their windmills are causing whales to die in numbers never seen before. Nobody does anything about that. They’re washing up on shore. I saw it this weekend: Three of them came up! You wouldn’t see it once a year; now they’re coming up on a weekly basis. The windmills are driving them crazy. They’re driving the whales, I think, a little batty.” [Sept. 25, 2023]
Fact check: If you ever want to feel ridiculous, try asking a scientist at the National Oceanic and Atmospheric Administration if windmills are making whales “a little batty.”
NOAA actively studies how “sound, vessel, and other human activities” impact marine life, Lauren Gaches, the director of NOAA Fisheries Public Affairs, told me over email. “At this point, there is no scientific evidence that noise resulting from offshore wind site characterization surveys could potentially cause mortality of whales,” she said.
An ongoing “unusual mortality event” for humpback whales has resulted in 200 whale deaths between 2016 and June 2023 along the Atlantic coast from Maine to Florida — that much is true. But “there are no known links between recent large whale mortalities and ongoing offshore wind surveys,” Gaches told me. NOAA’s fact page on whales and offshore wind explains that of “roughly 90 whales examined, about 40% had evidence of human interaction, either ship strike or entanglement.”
There has been some chatter about underwater surveying work disrupting whales, which may be true in the case of oil and gas surveys, which use seismic air guns to penetrate deep into the ocean floor. The surveying equipment used for offshore wind is, by contrast, used in 15-second bursts and limited to a specific area, “so the likelihood of an animal encountering and coming right into that sound beam is quite low,” Erica Staaterman, the deputy director for the Bureau of Ocean Energy Management’s Center for Marine Acoustics, said on a NOAA-hosted call with the press early last year.
As Ben Laws, the deputy chief of NOAA’s Permits and Conservation Division in the Office of Protected Resources, said on the same call, “There is no information that would support any suggestion that any of the equipment that’s being used in support of wind development for these site characterization surveys could directly lead to the death of a whale.”
“If you go out hunting and you happen to shoot a bald eagle, they put you in jail, like, for five years, right? They kill thousands of them with these windmills; nothing happens.” [Jan. 28, 2023]
“If you want to see a bird cemetery, go under a windmill sometime. You’ll see birds like you never saw. If you love birds, you’ll start to weep.” [Dec. 16, 2023]
Fact check: Trump has had a vendetta against wind turbines since long before he ever ran for president. “Wind farms are killing many thousands of birds,” reads one illustrative tweet from 2012. “They make hunters look like nice people!”
Lewis Grove is the director of wind and energy policy at the American Bird Conservancy, and he told me that while it’s “not necessarily as simple as Mr. Trump painted it out to be, wind turbines absolutely kill birds.”
But the context here is extremely important. Jason Ryan, a spokesperson for the American Clean Power Association, a leading renewable energy trade group, pointed me to research from the U.S. Fish & Wildlife Service that shows wind farms “represent just 0.03% of all human-related bird deaths in the U.S.” Grove likewise told me that, for the most part, bird deaths due to wind turbines do “not have population-level impacts.”
There are exceptions, such as an infamous wind farm in California’s Altamont Pass built in 1981 that “just happened to be in a place that was really heavily used by golden eagles,” Grove told me. Because golden eagle populations were already very low, having 100 or so killed a year by turbines was “unsustainable.” Even in a case like this, though, it behooves one to look at the whole picture: “They found it was a few individual turbines that were causing the damage,” Grove said. These days, around 60 golden eagles a year are killed in Alameda County, the Alameda Post reports, and the operating company must pay steep penalties for eagle deaths.
What’s more, “climate change is one of the greatest threats birds face, with two-thirds of North American species at risk of extinction due to our warming planet,” Jon Belak, senior manager of science and data analysis at The National Audubon Society, told me in a statement. “We need to build more wind and solar facilities to help slow the rise in global temperatures and protect birds and their habitats from a changing climate.”
Wind farms may not have population-level impacts on birds, but fracking does — “the onset of shale oil and gas production reduces subsequent bird population counts by 15%,” even after accounting for factors like weather and other land-use changes, according to one just-published, peer-reviewed study.
“Remember the windmills? ‘Darling, darling, I want to watch the president, I love him so much. I want to watch him on television tonight.’ ‘I’m sorry, but the wind isn’t blowing, you’ll have to wait ‘til another time.’ Windmills.” [March 26, 2022]
Fact check: “I mean, it’s possible with any mix of generation that if supply and demand aren’t equal, your TV will go out. That’s just physics,” Kyri Baker, an assistant professor of engineering at the University of Colorado, told me when I asked her if Trump’s scenario had any merit. In other words, a power outage could happen whether your electricity is coming from coal or natural gas or anything else. The difference, she said, is that “wind is by nature variable, intermittent. But it’s also not reliant on fuel like natural gas or coal plants or even nuclear plants are.”
What happens on days when there is no wind? “Grids are extremely regulated,” Baker explained to me. “There’s so many layers of redundancy that aim specifically to not have [an outage] happen.” A grid is made up of diverse electricity sources (for my visual learners, Canary imagines what a net-zero grid could look like here), as well as measures like offline backup generators, which can kick in if need be, so service isn’t disrupted.
Battery storage is another huge part of this equation. While they’re still fairly cutting-edge as climate technology goes, high-capacity batteries that can manage grid-scale energy needs are getting better and more plentiful.
“Stop with all of the windmills all over the place that are ruining the atmosphere.” [Jan. 20, 2022]
Fact check: Wind turbines do not damage the literal atmosphere.
But maybe Trump meant atmosphere as in “sense of place”? Most Americans don’t seem to think windmills are “ruining” anything. In a recent Heatmap poll, nearly eight in 10 Americans said they want the government to make it easier to build new wind farms. The Washington Post similarly found last year that about 70% of Americans said they wouldn’t mind living near a wind farm.
As my colleague Robinson Meyer has written, “American laws today give even a small, well-resourced minority plenty of tools to block a project” like a wind farm, and “what’s more, once that small group starts campaigning against a project, the public’s broad but shallow support for, say, a general technology can crater. That’s what happened recently in New Jersey, where a once broadly pro-wind public has turned against four proposed offshore wind farms.”
“It’s a very expensive form — probably the most expensive form of energy.” [Jan. 20, 2022]
Fact check: Wind in general is not the most expensive form of energy, but offshore wind is very expensive — for now.
Of the energy sources we’re currently used to, nuclear is usually cited as having the highest levelized cost of electricity — that is, it has the highest average cost per unit of electricity generated after construction, maintenance, and operation have been taken into account. Peaker plants — gas-powered plants that run just during times of peak demand — usually come in second.
Offshore wind is costly, with the levelized cost of electricity from a subsidized U.S. offshore wind project increasing “to $114.20 per megawatt-hour in 2023, up almost 50% from 2021 levels in nominal terms,” BloombergNEF reports. Many of the factors making offshore wind so expensive — including permitting delays, high interest rates, and supply chain issues — will abate with time. Meanwhile, onshore wind is one of the cheapest forms of electricity available and has boasted a “lower LCOE than gas plants since 2015,” Sustainable Energy in America reports.

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.”
