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.

Plus more insights from Heatmap’s latest event Washington, D.C.
At Heatmap’s event, “Supercharging the Grid,” two members of the House of Representatives — a California Democrat and a Colorado Republican — talked about their shared political fight to loosen implementation of the National Environmental Policy Act to accelerate energy deployment.
Representatives Gabe Evans and Scott Peters spoke with Heatmap’s Robinson Meyer at the Washington, D.C., gathering about how permitting reform is faring in Congress.
“The game in the 1970s was to stop things, but if you’re a climate activist now, the game is to build things,” said Peters, who worked as an environmental lawyer for many years. “My proposal is, get out of the way of everything and we win. Renewables win. And NEPA is a big delay.”
NEPA requires that the federal government review the environmental implications of its actions before finalizing them, permitting decisions included. The 50-year-old environmental law has already undergone several rounds of reform, including efforts under both Presidents Biden and Trump to remove redundancies and reduce the size and scope of environmental analyses conducted under the law. But bottlenecks remain — completing the highest level of review under the law still takes four-and-a-half years, on average. Just before Thanksgiving, the House Committee on Natural Resources advanced the SPEED Act, which aims to ease that congestion by creating shortcuts for environmental reviews, limiting judicial review of the final assessments, and preventing current and future presidents from arbitrarily rescinding permits, subject to certain exceptions.
Evans framed the problem in terms of keeping up with countries like China on building energy infrastructure. “I’ve seen how other parts of the world produce energy, produce other things,” said Evans. “We build things cleaner and more responsibly here than really anywhere else on the planet.”
Both representatives agreed that the SPEED Act on its own wouldn’t solve all the United States’ energy issues. Peters hinted at other permitting legislation in the works.
“We want to take that SPEED Act on the NEPA reform and marry it with specific energy reforms, including transmission,” said Peters.
Next, Neil Chatterjee, a former Commissioner of the Federal Energy Regulatory Commission, explained to Rob another regulatory change that could affect the pace of energy infrastructure buildout: a directive from the Department of Energy to FERC to come up with better ways of connecting large new sources of electricity demand — i.e. data centers — to the grid.
“This issue is all about data centers and AI, but it goes beyond data centers and AI,” said Chatterjee. “It deals with all of the pressures that we are seeing in terms of demand from the grid from cloud computing and quantum computing, streaming services, crypto and Bitcoin mining, reshoring of manufacturing, vehicle electrification, building electrification, semiconductor manufacturing.”
Chatterjee argued that navigating load growth to support AI data centers should be a bipartisan issue. He expressed hope that AI could help bridge the partisan divide.
“We have become mired in this politics of, if you’re for fossil fuels, you are of the political right. If you’re for clean energy and climate solutions, you’re the political left,” he said. “I think AI is going to be the thing that busts us out of it.”
Updating and upgrading the grid to accommodate data centers has grown more urgent in the face of drastically rising electricity demand projections.
Marsden Hanna, Google’s head of energy and dust policy, told Heatmap’s Jillian Goodman that the company is eyeing transmission technology to connect its own data centers to the grid faster.
“We looked at advanced transition technologies, high performance conductors,” said Hanna. “We see that really as just an incredibly rapid, no-brainer opportunity.”
Advanced transmission technologies, otherwise known as ATTs, could help expand the existing grid’s capacity, freeing up space for some of the load growth that economy-wide electrification and data centers would require. Building new transmission lines, however, requires permits — the central issue that panelists kept returning to throughout the event.
Devin Hartman, director of energy and environmental policy at the R Street Institute, told Jillian that investors are nervous that already-approved permits could be revoked — something the solar industry has struggled with under the Trump administration.
“Half the battle now is not just getting the permits on time and getting projects to break ground,” said Hartman. “It’s also permitting permanence.”
This event was made possible by the American Council on Renewable Energy’s Macro Grid Initiative.
On gas turbine backorders, Europe’s not-so-green deal, and Iranian cloud seeding
Current conditions: Up to 10 inches of rain in the Cascades threatens mudslides, particularly in areas where wildfires denuded the landscape of the trees whose roots once held soil in place • South Africa has issued extreme fire warnings for Northern Cape, Western Cape, and Eastern Cape • Still roiling from last week’s failed attempt at a military coup, Benin’s capital of Cotonou is in the midst of a streak of days with temperatures over 90 degrees Fahrenheit and no end in sight.

Exxon Mobil Corp. plans to cut planned spending on low-carbon projects by a third, joining much of the rest of its industry in refocusing on fossil fuels. The nation’s largest oil producer said it would increase its earnings and cash flow by $5 billion by 2030. The company projected earnings to grow by 13% each year without any increase in capital spending. But the upstream division, which includes exploration and production, is expected to bring in $14 billion in earnings growth compared to 2024. The key projects The Wall Street Journal listed in the Permian Basin, Guyana and at liquified natural gas sites would total $4 billion in earnings growth alone over the next five years. The announcement came a day before the Department of the Interior auctioned off $279 million of leases across 80 million acres of federal waters in the Gulf of Mexico.
Speaking of oil and water, early Wednesday U.S. armed forces seized an oil tanker off the coast of Venezuela in what The New York Times called “a dramatic escalation in President Trump’s pressure campaign against Nicolás Maduro.” When asked what would become of the vessel's oil, Trump said at the White House, “Well, we keep it, I guess.”
The Federal Reserve slashed its key benchmark interest rate for the third time this year. The 0.25 percentage point cut was meant to calibrate the borrowing costs to stay within a range between 3.5% and 3.75%. The 9-3 vote by the central bank’s board of governors amounted to what Wall Street calls a hawkish cut, a move to prop up a cooling labor market while signaling strong concerns about future downward adjustments that’s considered so rare CNBC previously questioned whether it could be real. But it’s good news for clean energy. As Heatmap’s Matthew Zeitlin wrote after the September rate cut, lower borrowing costs “may provide some relief to renewables developers and investors, who are especially sensitive to financing costs.” But it likely isn’t enough to wipe out the effects of Trump’s tariffs and tax credit phaseouts.
GE Vernova plans to increase its capacity to manufacture gas turbines by 20 gigawatts once assembly line expansions are completed in the middle of next year. But in a presentation to investors this week, the company said it’s already sold out of new gas turbines all the way through 2028, and has less than 10 gigawatts of equipment left to sell for 2029. It’s no wonder supersonic jet startups, as I wrote about in yesterday’s newsletter, are now eyeing a near-term windfall by getting into the gas turbine business.

The European Union will free more than 80% of the companies from environmental reporting rules under a deal struck this week. The agreement between EU institutions marks what Politico Europe called a “major legislative victory” for European Commission President Ursula von der Leyen, who has sought to make the bloc more economically self-sufficient by cutting red tape for business in her second term in office. The rollback is also a win for Trump, whose administration heavily criticized the EU’s green rules. It’s also a victory for the U.S. president’s far-right allies in Europe. The deal fractured the coalition that got the German politician reelected to the EU’s top job, forcing her center-right faction to team up with the far right to win enough votes for secure victory.
Ravaged by drought, Iran is carrying out cloud-seeding operations in a bid to increase rainfall amid what the Financial Times clocked as “the worst water crisis in six decades.” On Tuesday, Abbas Aliabadi, the energy minister, said the country had begun a fresh round of injecting crystals into clouds using planes, drones, and ground-based launchers. The country has even started developing drones specifically tailored to cloud seeding.
The effort comes just weeks after the Islamic Republic announced that it “no longer has a choice” but to move its capital city as ongoing strain on water supplies and land causes Tehran to sink by nearly one foot per year. As I wrote in this newsletter, Iranian President Masoud Pezeshkian called the situation a “catastrophe” and “a dark future.”
The end of suburban kids whiffing diesel exhaust in the back of stuffy, rumbling old yellow school buses is nigh. The battery-powered bus startup Highland Electric Fleets just raised $150 million in an equity round from Aiga Capital Partners to deploy its fleets of buses and trucks across the U.S., Axios reported. In a press release, the company said its vehicles would hit the streets by next year.
Cities across the state are adopting building codes that heavily incentivize homeowners to make the switch.
A quiet revolution in California’s building codes could turn many of the state’s summer-only air conditioners into all-season heat pumps.
Over the past few months, 12 California cities have adopted rules that strongly incentivize homeowners who are installing central air conditioning or replacing broken AC systems to get energy-efficient heat pumps that provide both heating and cooling. Households with separate natural gas or propane furnaces will be allowed to retain and use them, but the rules require that the heat pump becomes the primary heating system, with the furnace providing backup heat only on especially cold days, reducing fossil fuel use.
These “AC2HP” rules, as proponents call them, were included in a routine update of California building codes in 2024. Rather than make it mandatory, regulators put the heat pump rule in a package of “stretch codes” that cities could adopt as they saw fit. Moreno Valley, a city in Riverside County, east of Los Angeles, was the first to pass an ordinance adopting the AC2HP code back in August. A steady stream of cities have followed, with Los Gatos and Portola Valley joining the party just last week. Dylan Plummer, a campaign advisor for Sierra Club's Building Electrification Campaign, expects more will follow in the months to come — “conversations are moving” in Los Angeles and Sacramento, as well, he told me.
“This is a consumer protection and climate policy in one,” he said. As California gets hotter, more households in the state are getting air conditioners for the first time. “Every time a household installs a one-way AC unit, it’s a missed opportunity to install a heat pump and seamlessly equip homes with zero-emission heating.”
This policy domino effect is not unlike what happened in California after the city of Berkeley passed an ordinance in 2019 that would have prohibited new buildings from installing natural gas. The Sierra Club and other environmental groups helped lead more than 70 cities to follow in Berkeley’s footsteps. Ultimately, a federal court overturned Berkeley’s ordinance, finding that it violated a law giving the federal government authority over appliance energy usage. Many of the other cities have since suspended their gas bans.
Since then, however, California has adopted state-wide energy codes that strongly encourage new buildings to be all-electric anyway. In 2023, more than 70% of requests for service lines from developers to Pacific Gas & Electric, the biggest utility in the state, were for new all-electric buildings. The AC2HP codes tackle the other half of the equation — decarbonizing existing buildings.
A coalition of environmental groups including the Sierra Club, Earthjustice, and the Building Decarbonization Coalition are working to seed AC2HP rules throughout the state, although it may not be easy as cost-of-living concerns grow more politically charged.
Even in some of the cities that have adopted the code, members of the public worried about the expense. In Moreno Valley, for instance, a comparatively low-income community, six out of the seven locals who spoke on the measure at a meeting in August urged elected officials to reject it, and not just because of cost — some were also skeptical of the technology.
In Glendale, a suburb of Los Angeles which has more socioeconomic diversity, all four commenters who spoke also urged the council to reject the measure. In addition to cost concerns, they questioned why the city would rush to do something like this when the state didn’t make it mandatory, arguing that the council should have held a full public hearing on the change.
In Menlo Park, on the other hand, which is a wealthy Silicon Valley suburb, all five speakers were in support of the measure, although each of them was affiliated with an environmental group.
Heat pumps are more expensive than air conditioners by a couple of thousands of dollars, depending on the model. With state and local incentives, the upfront cost can often be comparable. When you take into account the fact that you’re moving from using two appliances for heating and cooling to one, the equipment tends to be cheaper in the long run.
The impacts of heat pumps on energy bills are more complicated. Heat pumps are almost always cheaper to operate in the winter than furnaces that use propane or electric resistance. Compared to natural gas heating, though, it mostly depends on the relative cost of gas versus electricity. Low-income customers in California have access to lower electricity rates that make heat pumps more likely to pencil out. The state also recently implemented a new electricity rate scheme that will see utilities charge customers higher fixed fees and lower rates per kilowatt-hour of electricity used, which may also help heat pump economics.
Matthew Vespa, an senior attorney at Earthjustice described the AC2HP policy as a way to help customers “hedge against gas rates going up,” noting that gas prices are likely to rise as the U.S. exports more of the fuel as liquified natural gas, and also as gas companies lose customers. “It’s really a small incremental cost to getting an AC replaced with a lot of potential benefits.”
The AC2HP idea dates back to a 2021 Twitter thread by Nate Adams, a heat pump installer who goes by the handle “Nate the House Whisperer.” Adams proposed that the federal government should pay manufacturers to stop producing air conditioners and only produce heat pumps. Central heat pumps are exactly the same as air conditioners, except they provide heating in addition to cooling thanks to “a few valves or ~$100-300 in parts,” Adam said at the time.
The problem is, most homeowners and installers are either unfamiliar with the technology or skeptical of it. While heat pumps have been around for decades and are widespread in other parts of the world, especially in Asia, they have been slower to take off in the United States. One reason is the common misconception that they don’t work as well as furnaces for heating. Part of the issue is also that furnaces themselves are less expensive, so heat pumps are a tougher sell in the moment when someone’s furnace has broken down. Adams’ policy pitch would have given people no choice but to start installing heat pumps — even if they didn’t use them for heating — getting a key decarbonization technology into homes faster than any rebate or consumer incentive could, and getting the market better acquainted with the tech.
The idea gained traction quickly. An energy efficiency research and advocacy organization called CLASP published a series of reports looking at the potential cost and benefits, and a manufacturer-focused heat pump tax credit even made its way into a bill proposal from Senator Amy Klobuchar in the runup to the 2022 Inflation Reduction Act. While rules that target California homeowners obviously won’t have the nation-wide effect that Adams’ would have, they still have the potential to send a strong market signal, considering California is the fifth largest economy in the world.
The AC2HP codes, which start going into effect next year, will help smooth the road to another set of building electrification rules that will apply in some parts of the state beginning in 2029. At that point, households in the Bay Area will be subject to new air quality standards that require all newly installed heating equipment to be zero-emissions — in other words, if a family’s furnace breaks down, they’ll have to replace it with a heat pump. State regulators are developing similar standards that would apply statewide starting in 2035. The AC2HP rule ensures that if that same family’s air conditioner breaks between now and then, they won’t end up with a new air conditioner, which would eventually become redundant.
The rule is just one of a bunch of new tools cities are using to decarbonize existing buildings. San Francisco, for example, adopted an even stricter building code in September that requires full, whole-home electrification when a building is undergoing a major renovation that includes upgrades to its mechanical systems. Many cities are also adopting an “electrical readiness” code that requires building owners to upgrade their electrical panels and add wiring for electric vehicle charging and induction stoves when they make additions or alterations to an existing building.
To be clear, homeowners in cities with AC2HP laws will not be forced to buy heat pumps. The code permits the installation of an air conditioner, but requires that it be supplemented with efficiency upgrades such as insulating air ducts and attics — which may ultimately be more costly than the heat pump route.
“I don’t think most people understand that these units exist, and they’re kind of plug and play with the AC,” said Vespa.
