Fact-checking a Trump-inspired fear.
As someone on the “will this thing kill me” beat, I was paying close attention when the former president of the United States recently expressed concern about electric-powered boats — apparently, the new aquatic twist on his electric car rant. “Let’s say your boat goes down and I’m sitting on top of this big powerful battery and the boat’s going down,” Donald Trump mused to a group of supporters in the landlocked state of Iowa. “Do I get electrocuted?”
Trump then dramatically upped the stakes by imagining the sinking electric boat was also being circled by a shark. “So I have a choice of electrocution or shark,” he went on. “You know what I’m going to take? Electrocution. I will take electrocution every single time.”
I wanted to find out if it was actually possible for Trump to be electrocuted and/or eaten by a shark (you know, hypothetically). It was a question that inspired many related, obsessive searches: What about if you drive an electric vehicle into a lake — would that electrocute you? Are first responders afraid to help people in submerged EVs? Would they leave you inside to die?!
Like I said, I can be a little morbid.
Below, I attempt to sort electrocution fact from electrocution fiction, with a few detours thrown in.
People have been using electricity to power their boats for over 120 years. In fact, until the high-energy storage density of oil became obvious around the turn of the century, electric boats actually enjoyed a bit of a heyday. (RIP to the electric canoe).
Moreover, if you’ve ever been on a marine vessel with any more sophistication than a rowboat, it probably had a battery and an electrical system on board, even if it wasn’t powered by an electric motor. Standard 12-volt marine batteries are used for everything from starting the main engine to running the lights, radio, or a trolling motor on board.
The modern iteration of the fully electrified boat movement is still in its relative infancy and faces some big challenges. But the short version is, we’ve been using electricity at sea for a long time and have gotten pretty good at not electrocuting ourselves. And the potential electrocution problems that do exist usually aren’t exclusive to high-voltage electric boats, but gas-powered ones as well.
First of all, battery packs on electric boats are designed to be watertight — duh, because they’re
on a boat. Believe it or not, electric boat makers have taken into account the fact that their products could, in a worst-case scenario, end up underwater. A spokesperson for Arc Boat Company, a flashy new player in the electric boat space, pointed me to their FAQ which explains that “our fault table — a list of possible points of failure and what to do about each one — is hundreds of lines long, meaning we’ve thought about, tested, and planned for every scenario you might encounter on and off the water.” (This seems like a job I could be good at.)
In fact, all the electric boat manufacturers I was in touch with said they meet a waterproofing standard that is either at, or just below, what is required for a submarine. The high-voltage batteries are additionally kept in “puncture-resistant shells,” so even if the boat somehow got completely mangled, the battery won’t just be openly exposed to the water.
Still, you definitely don’t want to sit on an exposed “big powerful battery,” as Trump suggests in his scenario, since you could theoretically interrupt the closed loop of a DC battery’s electrical circuit and get shocked. But just being on an electric boat that is sinking does not inherently expose you to electrocution danger.
Electric shock drowning is caused by faulty wiring at a dock or a marina leaking 120-volt alternating current into the water. That electricity can potentially kill a nearby swimmer on its own, or cause them to become incapacitated and drown.
This overwhelmingly happens in lakes and rivers, since human bodies are a better conductor of electricity than fresh water but not saltwater. “In saltwater, the human body only slows electricity down, so most of it will go around a swimmer on its way back to ground unless the swimmer grabs hold of something — like a propeller or a swim ladder — that’s electrified,” BoatUS, a marine insurance company and safety advocacy group, explains in its publication Seaworthy. “In fresh water, the current gets ‘stuck’ trying to return to its source and generates voltage gradients that will take a shortcut through the human body.”
While it’s possible that a poorly maintained electric boat charging station could cause this sort of leak, it’s not a danger exclusive to the electric boat world; gas-powered boats hooked to shore power kill people every year, as well. Regardless, this is why you should never, ever swim around boat docks, especially at lakes.
If you are worried about sea life getting electrocuted by a high-voltage shipwreck, don’t be. When a battery is underwater, its current will flow into the water between its two terminals. This is bad for the battery (it’ll cause it to rapidly discharge) but you don’t have to worry about the entire ocean or lake getting filled with charge and electrocuting everything in it; high-voltage batteries are powerful but not nearly that powerful. If a shark is in the immediate vicinity of the battery — like, trying to eat it — it might potentially get hurt, but this whole premise is also starting to get absurd with this many “what ifs” piled on top of each other. (Really, the environmental hazard of a leaking lithium battery on the seafloor is probably the greater cause for concern.)
You’ll have bigger problems than electrocution!
Like electric boats, EV batteries are obsessively insulated and the cars are designed with a number of fail-safes to isolate the battery in the case of an accident. Again, the people who thought up these things have already considered the worst-case scenarios. (Plus, getting sued for repeatedly electrocuting anyone who drives through a puddle is not good business).
What’s important to understand is that unlike the 12-volt batteries used in gas-powered cars, which are harmlessly grounded to the car’s large chassis, high-voltage systems in EVs use a floating ground, which helps prevent you from being electrocuted if the car becomes submerged. “It’s not grounded chassis — there is no return path for a vehicle that has been submerged to return that charge,” Joe McLaine, a safety engineer with General Motors, told me. “And if there [are] any faults or anomalies with the high voltage system, and it’s operating in normal functioning ranges, it’s going to shut off anyway.”
Yes — and it’s also true of driving in the rain, or washing your car, or charging in a downpour.
Trying to drive an EV through deep water is not a great idea for a number of very good reasons, but fear of electrocution isn’t one of them. The most likely scenario is that the water will cause any less-well-insulated electronic components to short out, causing the car to die — which is what happened when Motor Mythbusterstried to drive a Nissan Leaf through a water-filled trench.
Of course, gas-powered cars don’t love driving in floods, either, and there is some reason to believe that EVs might actually do better in flood conditions than their counterparts.
Back in 2016, Elon Musk tweeted that the “Model S floats well enough to turn it into a boat for short periods of time.” Just searching the words “EV” or “Tesla” and “flood” or “boat mode” will lead you to tons of videos of EVs plowing through deep bodies of water.
Don’t … do this. Most flood-related deaths occur in cars, and this fact doesn’t change just because your vehicle has a plug. Additionally, just because an EV drove through a flood successfully in a short video doesn’t mean there was no lasting damage from the water (which, it should be added, isn’t covered under warranty).
Florida’s State Fire Marshal’s Office reported there were at least 21 EV battery fires in the aftermath of Hurricane Ian in 2022. This is specifically a phenomenon caused by saltwater storm surge: When the car eventually dries out, the salt residue can remain behind on the battery, creating conductive “bridges” that lead to short circuits and fires.
This is still fairly rare: “The odds that your electric battery pack is on fire in Florida are about the same odds of you getting struck by lightning,” Joe Britton, the executive director of the Zero Emission Transportation Association, told Utility Drive. To be safe, FEMA recommends that any EVs flooded by saltwater be moved at least 50 feet away from any structures, other vehicles, or combustibles. And if you are expecting storm surge, move your EV preemptively to higher ground.
Tesla echoes this advice: “As with any electric vehicle, if your Tesla has been exposed to flooding, extreme weather events, or has otherwise been submerged in water (especially in salt water), treat it as if it’s been in an accident and contact your insurance company for support,” the company writes in its user manual.
“That is not true,” McLaine, the safety engineer with General Motors, told me. McLaine is responsible for GM’s Battery Electric Vehicle First Responder Training program, which has educated over 5,000 first- and second-responders in 25 different locations across the U.S. and Canada, and is focused on dispelling some of the rumors and misinformation around electric cars.
In addition to trainings like GM’s, a growing familiarity with the thousands of EVs now on the road has also made first responders more confident when responding to bad accidents. Orange cables are used to easily identify high-voltage components, which are placed “in areas and locations in the vehicle in which first responders typically wouldn’t have access to anyway,” McLaine explained.
First responders are trained to disable the high-voltage systems in an EV just like they would snip the cut loops around a 12-volt battery in a gas-powered vehicle accident. Additionally, most manufacturers make it extremely easy to find individual emergency response guides for their vehicles online, and there are various hotlines available for first- and second-responders when EV-related questions arise.
What First Responders Do in an EV Accidentwww.youtube.com
As for first responders handling cars that have been fully or partially submerged: Pretty much all of the emergency response documents I could find stated some version of “A submerged electric vehicle does not have a high voltage potential on the metal vehicle body, and is safe to touch” (this one specifically comes from the papers for the RAV 4 EV). Though first responders need to be careful with cutting into crushed cars, there are no shocking surprises when it comes to simply handling a submerged EV.
Are you kidding me? Electrocution would at least be quick! Trump got that part right: In this round of “would you rather,” you should take electrocution every time.

The fundamentals are the same — it’s the tone that’s changed.
At some point in the past month, the hydrogen fuel cell developer Plug Power updated its website. Beneath a carousel explaining the hydrogen ecosystem and solutions for transporting fuel, the company’s home page now contains a section titled “Hydrogen at Work.”
“Hydrogen is key to energy independence, providing clean, reliable power while reducing reliance on imported fuels,” the text in this new box reads. “Plug’s hydrogen and fuel cell solutions strengthen the energy grid and enhance national security, positioning the U.S. as a leader in the global energy transition.”
It is fairly ordinary website copy, but to a keen reader, the text jumps out as an obvious Trump 2.0 tell. Plug Power — like many green economy companies — has pivoted to meet the political and economic moment, where “energy independence” and “energy dominance” are in and “climate” and “sustainability” are out.
“I am actually shocked every time I look at the website of a climate tech company that still uses the language from 12 months ago, from four months ago — that doesn’t do them any good,” Peter Atanasoff, the managing director and vice president of Scratch Media and Marketing, which helps B2B technology companies and climate tech businesses achieve growth and recognition, told me.
The shift in language is more significant than just brands chasing the latest buzzwords.
The first Trump administration saw broad-based pushback from the business community against Trump’s more inflammatory positions, especially by consumer-facing brands that played to the pussy hat-wearing, brunch-and-protest attitudes of the time. The CEOs of Facebook (now Meta), Nike, and Google issued statements of disappointment when the U.S. pulled out of the Paris Climate Agreement in 2017, and Tesla CEO Elon Musk even dropped out of the president’s business council over the decision. It was, needless to say, a very different time.
During Trump’s second term, he promised “retribution.” Many of the more moderate voices from his first administration are long gone, and there’s a palpable fear among nonprofits and businesses of drawing the wrong kind of attention from Washington, losing grant funding for saying the wrong thing. “The real trigger” for resulting differences in branding between the first and second Trump administrations has been “the change of tone and change of economic policy,” Atanasoff told me. “It is explicit opposition to any of these technologies."
The administration has launched an all-out assault not just on climate policy, but also on the very language of the energy transition. In a February memo obtained by E&E News, the Federal Emergency Management Agency listed 34 words to be erased from official documentation, including “global warming,” “carbon footprint,” “net zero,” and even “green.” As I’ve covered for Heatmap, farmers applying for Department of Agriculture grants have been encouraged to resubmit proposals with climate-focused language removed and “refocus … on expanding American energy production.” And at the National Oceanic and Atmospheric Administration, scientists have quickly learned to pivot to talking about “air pollution” rather than emissions, contending with a banned-words list of their own.
Lobbyists and clean energy companies that want to be in the administration’s good graces have adapted, as well. That has changed the tenor of green business at large. Alexander Bryden, who runs the Washington, D.C. office of Browning Environmental Communications, told me over email that tweaking brand language is “typical after any change of administration, particularly when there are significant shifts in policy.” But especially for organizations in the public eye, “it’s more important than ever to highlight the historic and potential economic benefits of environmental solutions — and show how they are supported by, and benefit, people across the political spectrum.”
The actual fundamentals of green business haven’t changed, though. On the contrary, in the first quarter of 2025, venture capitalists and private equity firms invested more than $5 billion in climate tech startups in the U.S., a 65% increase from the same period a year earlier, according to PitchBook data. While there are certainly obstacles like supply chain uncertainty and tariffs to contend with, especially for clean energy manufacturing, on the whole “it’s still a great time to start a climate startup,” Tommy Leep, the founder of the software-focused venture firm Jetstream, told my colleague Katie Brigham last November. His caveat? “Just don’t call it a climate startup.”
Roger Ballentine, the president of the management consulting service Green Strategies and the chairman of the White House Climate Change Task Force under President Bill Clinton, explained this thinking to me. “It’s what I refer to as climate capitalism, which is the realization that by incorporating climate change and its risks and opportunities into your business strategy, you’re actually going to be a more successful, more profitable, and more competitive company,” he said. Even with the recent economic turbulence, “That hasn’t changed. That’s not going to change.”
Where you do see adjustments, however, is “around the edges,” per Ballentine. Companies are attempting to match the frequency of the administration and, in turn, the broader policy ecosystem — a frequency that tends to be aggressive, assertive, and heavy on words like “dominance” and “security.” It might also take the form of decreasing the volume at which companies had previously shouted their climate bona fides.
Anya Nelson, the senior vice president of public relations at Scratch M+M, said her team has also advised touting “American-made production” in brand messaging, and reframing copy to focus on “the positive impacts and immediate business benefits” of the companies, rather than more idealistic messaging about climate goals that may have had stronger resonance during the Biden administration.
At this point, you may have noticed that I haven’t quoted any corporate brand officers. That’s not because I didn’t try to talk to any. (Even Plug Power, my example at the beginning of this story, didn’t respond to a request for comment on the change in their messaging.) Though the sudden prevalence of terms like “energy dominance” becomes conspicuous once you start to look for them, no one wants to draw the wrong kind of attention from the administration. It’s part of a greater trend of clamming up that my colleagues and I have experienced across sectors in our reporting, and at a time when even the word “green” can give you a black mark, I can’t say I don’t understand.
Ballentine, the Green Strategies president, dismissed reading too much into how language itself changes under President Trump. “If yesterday a new technology company was touting itself as a climate solution, and now it’s touting itself as a way to achieve energy dominance — I don’t care,” he said.
His thinking was more pragmatic. “Good business remains good business,” Ballentine went on. “Around the edges, will things change? Yes. General belt tightening? Yes. Fundamental change of direction? No.”
It might sound like branding agencies are encouraging companies to “play along” with the administration, but Nelson of Scratch M+M stressed that wasn’t what she was trying to say. At the end of the day, “your end goal is to be a viable company, right?” she said. “To be a thriving company that is going to change the world, first and foremost, you need to make sure you don’t go out of business.” The message might be more accurately summarized as “read the room.”
A report from Heatmap’s San Francisco Climate Week event with Tom Steyer.
Last Thursday at San Francisco Climate Week, Heatmap hosted an event with a lineup of industry leaders and experts to discuss the most promising up-and-coming climate tech innovations amidst a backdrop of tariff and tax credit uncertainty.

First up, Heatmap executive editor Robinson Meyer sat down with Tom Steyer, the billionaire investor and co-founder of Galvanize Climate Solutions, to explore the most promising climate technologies to scale. “No one's going to adopt new technologies to be nice,” Steyer noted. “They're gonna adopt new technologies because they're better, because they're a better deal, because they're cheaper or in some ways solve a pain point for the customer.” Steyer went on to emphasize that there is at least one “transformational and disruptive” idea for every six verticals in the climate industry — for example, measuring carbon sequestration in nature with machine learning andAI, a concept that was “literally unimaginable 5 years ago.”

As for the Trump-sized elephant in the room, Steyer encouraged climate tech startups to focus on “good leadership” as well as the willingness to adapt in this uncertain moment. “You’re gonna have hard times, and the world is going to change, and you’re going to have to figure out what to do,“ he said. Steyer also noted that all Americans, not only those working in climate tech, should understand the energy transition as a background condition of their careers. “If you want to be a screenwriter (...) be a screenwriter. But it’s really important that you put [the energy transition] into your screenwriting. If you‘re a banker (...) be a banker with an awareness of this issue. Bank the good stuff, not the bad stuff,” Steyer explained. He finished up the discussion with a remembrance of the late Pope Francis, a “tremendous human being for the planet.”
Sam D'Amico and Nico Lauricella.Sean Vranizan
Also on Thursday was a lightning talk between Nico Lauricella, Heatmap’s CEO and editor in chief, and Sam D’Amico, the founder and CEO of Impulse Labs, which sponsored the event. D'Amico explained that in addition to being an induction stove, Impulse’s Cooktop is “a way to get battery storage into people's homes” — a “concept car” for using batteries in appliances to create a more decentralized grid. Lauricella and D’Amico also discussed the impacts of Trump’s tariffs on clean tech companies like Impulse, with D’Amico advising other founders in the room to build prototypes based on the supply chain and to make sure they have options in terms of where their products are manufactured so they can keep up with changing trade policies.

Lastly, Heatmap News staff writer Katie Brigham hosted a panel with Gabriel Kra, managing director and co-founder at Prelude Ventures, Clea Kolster, partner and head of science at Lowercarbon Capital, and Rajesh Swaminathan, partner at Khosla Ventures. The group spoke about the unique circumstances facing investors in the climate technology space, what their firms are looking for when investing in the newest climate innovations, and how AI fits into the picture.

All three panelists acknowledged that it’s a delicate time for clean tech investors and companies alike. “Volatility and uncertainty are the enemies of running and planning a business,” warned Kra. The true cost of the tariffs is therefore extremely high, Kra explained. Kolster agreed that things are generally gloomy in the investment space, but also highlighted the technologies that are currently thriving. Carbon removal, she pointed out, “is going better than ever. Contracts are being inked right now, in the past few weeks.” The companies and technologies she’s excited about, Kolster added, are building “cheaper, better, faster,” as Steyer pointed out earlier in the evening.
Swaminathan added that there will always be a certain element of risk when it comes to investing in emerging technologies. “Clean tech companies have so many single points of failure,” he said. “And you have to prop up each part with the right leadership team. You have to have strong pillars so that [your company] doesn’t break.”

On DOJ lawsuits, reconciliation, and solar permitting
Current conditions: A month out from the start of hurricane season, the North Atlantic Ocean is about 2 degrees Fahrenheit cooler than it was this time last year• Passenger ferry crossings between New Zealand’s North and South Island remain suspended through Friday afternoon due to a severe windstorm• Thunderstorms are expected to settle over Louisville, Kentucky, this afternoon, leading to a potentially wet Kentucky Derby on Saturday at Churchill Downs.
The Justice Department filed lawsuits this week against Hawaii, Michigan, New York, and Vermont to block the states’ climate-motivated lawsuits against fossil fuel companies. The government’s lawsuit against Hawaii and Michigan, filed on Wednesday, seeks to block the states from suing major oil and gas companies over alleged climate damages, which the DOJ argues obstructs the Environmental Protection Agency’s authority to regulate greenhouse gas emissions. On Thursday, the DOJ also filed suit against New York and Vermont over their climate superfund laws, which would require fossil fuel companies to pay for damages caused by climate change, calling it a “transparent monetary-extraction scheme.” Attorney General Pamela Bondi argued all four laws are “burdensome and ideologically motivated” and “threaten American energy independence and our country’s economic and national security.”
The House Natural Resources Committee released its portion of Republicans’ budget package on Thursday evening. The proposal goes to markup next week, and is subject to change, but includes several significant measures across its 96 pages. Some include:
In a statement slamming the bill, Lydia Weiss, the senior director of government relations at The Wilderness Society, said the proposals in sum will “fund tax cuts for the rich while doing nothing to help the average American taxpayer.” You can read the full contents of the bill here.
The Bureau of Land Management has approved a new solar project in Yuma County, Arizona, after a temporary halt on permitting. The move “appears to be the first utility-scale solar facility on federal acreage approved by the Trump administration,” my colleague Jael Holzman writes in The Fight. The BLM additionally released a draft environmental review of a separate solar project, also in Arizona.
As Jael notes, “The fact BLM is willing to admit other solar projects could advance later on is significant after the sputtering seen in the earliest days of the Trump administration.” Her caveat, however, is that it’s unclear if this means solar permitting is a beneficiary of the president’s “energy dominance” agenda, or if “at any moment, a news cycle or disgruntled legislator could steal the president’s ear and make him angry at solar power.”

The major reinsurance company Swiss Re has released a lengthy report about the upward trend of insured losses in the United States. Among its findings:
Read more of Swiss Re’s findings in the report here.
The Trump administration has ordered the National Science Foundation to stop awarding new grants or supplying funds for existing grants “until further notice,” according to an email reviewed by Nature. Before the funding freeze, NSF leadership had recently directed its staffers to return grant proposals concerning “topics or activities” not “in alignment with agency priorities” to their applicants.
In the past two weeks, the NSF has terminated $739 million worth of grants, Nature adds. As one NSF staffer told the publication, the Trump administration is “butchering the gold standard merit review process that was established at NSF over decades.” Colin Carlson, who is researching pandemic-causing viruses at Yale University with a team of 50 funded by a $12.5 million NSF grant, said the freeze will “destroy people’s labs.” The NSF has also contributed enormously to climate science over the years, including funding the first major ice core drilling project in Greenland in 1980 to study historical carbon dioxide data, and more recently, using advanced climate modeling to predict extreme weather events better.
“Saying that the U.S. is striving for energy dominance except in the clean energy sector is like opening a steakhouse and forgetting the meat.” —Former Secretary of Energy Jennifer Granholm, writing for Heatmap about why real energy dominance requires preserving the IRA.
