“Do you ever think about electric cars?”
Between solar roofs, home batteries, and electric vehicles, Tesla could potentially “do more to fight climate change than any other company — perhaps any other entity — in the world,” Walter Isaacson muses in his much-anticipated biography of Elon Musk, out Tuesday.
But while the central character is at times painted as a heroic visionary (Isaacson’s previous subjects have included Steve Jobs, Einstein, and Leonardo da Vinci), the biography also makes it clear that Tesla’s mercurial CEO isn’t always the easiest to work with — or, in the blunter words of Bill Gates, he can be “super mean.” Here are some of the most surprising moments about climate and energy shared in Isaacson’s Elon Musk:
On Musk’s EV passion:
When Elon went with [Peter] Nicholson’s daughter, Christie, to a party one evening, his first question was “Do you ever think about electric cars?” As he later admitted, it was not the world’s best come-on line.
On education:
Musk also focused on electric cars. He and [his friend Robin] Ren would grab lunch from one of the food trucks and sit on the campus lawn, where Musk would read academic papers on batteries. California had just passed a requirement mandating that 10 percent of vehicles by 2003 had to be electric. “I want to go make that happen,” Musk said.
Musk also became convinced that solar power, which in 1994 was just taking off, was the best path toward sustainable energy. His senior paper was titled “The Importance of Being Solar.” He was motivated not just by the dangers of climate change but also by the fact that fossil fuel reserves would start to dwindle. “Society will soon have no option but to focus on renewable power sources,” he wrote. His final page showed a “power station of the future,” involving a satellite with mirrors that would concentrate sunlight onto solar panels and send the resulting electricity back to Earth via a microwave beam. The professor gave him a grade of 98, saying it was a “very interesting and well written paper, except the last figure that comes out of the blue.”
On investing in batteries:
Eager to keep the conversation going, [Tesla co-founder JB] Straubel changed the topic to his idea for building an electric vehicle using lithium-ion batteries. “I was looking for funding and being rather shameless,” he says. Musk expressed surprise when Straubel explained how good the batteries had become. “I was going to work on high-density energy storage at Stanford,” Musk told him. “I was trying to think of what would have the most effect on the world, and energy storage along with electric vehicles were high on my list.” His eyes lit up as he processed Straubel’s calculations. “Count me in,” he said, committing to provide $10,000 in funding.
On building the Gigafactory:
The idea that Musk proposed in 2013 was audacious: build a gigantic battery factory in the U.S. […] There was one problem, Straubel recalls. “We had no clue how to build a battery factory.”
So Musk and Straubel decided to pursue a partnership with their battery supplier, Panasonic […] Musk and Straubel were invited to Japan by Panasonic’s new young president Kazuhiro Tsuga. “It was a come-to-Jesus session where we had to make him truly commit that we were going to build the insane Gigafactory together,” Straubel says.
The dinner was a formal, multicourse affair at a traditional low-table Japanese restaurant. Straubel was fearful about how Musk would behave. “Elon can be so much hell and brimstone in meetings and just unpredictable as all get out,” he says. “But I’ve also seen him flip a switch and suddenly be this incredibly effective, charismatic, high-emotional-intelligence business person, when he has to do it.” At the Panasonic dinner, the charming Musk appeared. He sketched out his vision for moving the world to electric vehicles and why the two companies should do it together. “I was mildly shocked and impressed, because, whoa, this is not like how Elon usually was on other days,” says Straubel. “He’s a person who’s all over the map, and you don’t know what he’s going to say or do. And then, all of a sudden, he pulls it all together.”
On the origins of SolarCity:
“I want to start a new business,” Musk’s cousin Lyndon Rive said as they were driving in an RV to Burning Man, the annual art-and-tech rave in the Nevada desert, at the end of the summer of 2004. “One that can help humanity and address climate change.” “Get into the solar industry,” Musk replied. Lyndon recalls that the answer felt like “my marching orders.” With his brother Peter, he started work on creating a company that would become SolarCity. “Elon provided most of the initial funding,” Peter recalls. “He gave us one clear piece of guidance: get to a scale that would have an impact as fast as possible.”
On buying SolarCity:
When Musk announced the deal in June 2016, he called it a “no-brainer” that was “legally and morally correct.” The acquisition fit with his original “master plan” for Tesla, which he had written in 2006: “The overarching purpose of Tesla Motors is to help expedite the move from a mine-and-burn hydrocarbon economy towards a solar electric economy.”
On hating SolarCity:
The solar roof project caused enormous friction between Musk and his cousins. In August 2016, around the time he was teasing the new product, Peter Rive invited Musk to inspect a version that the company had installed on a customer’s roof. It was a standing-seam metal roof, meaning the solar cells were embedded in sheets of metal rather than tiles. When Musk drove up, Peter and fifteen people were standing in front of the house. “But as often happened,” Peter recalled, “Elon showed up late and then sat in the car looking at his phone while we all just waited very nervously for him to get out.” When he did, it was clear that he was furious. “This is shit,” Musk explained. “Total fucking shit. Horrible. What were you thinking?”
On really, really hating SolarCity:
There were four versions [of solar roofs], including those that looked like French slate and Tuscan barrel tiles, along with a house that featured the metal roof that Musk hated. When Musk visited two days before the scheduled event and saw the metal version, he erupted. “What part of ‘I fucking hate this product’ don’t you understand?” One of the engineers pushed back, saying it looked okay to him and that it was the easiest to install. Musk pulled Peter aside and told him, “I don’t think this guy should be on the team.” Peter fired the engineer and had the metal roof removed before the public event.
On cutting solar roof installation time:
[…] Musk clambered up a ladder to the peak of the roof, where he stood precariously. He was not happy. There were too many fasteners, he said. Each had to be nailed down, adding time to the installation process. “Instead of two nails for each foot, try it with only one,” he ordered. “If the house has a hurricane, the whole neighborhood is fucked up, so who cares? One nail is going to be fine.” Someone protested that could lead to leaks. “Don’t worry about making it as waterproof as a submarine,” he said. “My house in California used to leak. Somewhere between sieve and submarine should be okay.” For a moment he laughed before returning to his dark intensity.
On talking climate with Bill Gates:
“Hey, I’d love to come see you and talk about philanthropy and climate,” Bill Gates said to Musk when they happened to be at the same meeting in early 2022. Musk’s stock sales had led him, for tax reasons, to put $5.7 billion into a charitable fund he had established. Gates, who was then spending most of his time on philanthropy, had many suggestions he wanted to make. They’d had friendly interactions a few times in the past, including when Gates brought his son Rory to SpaceX. [...] Gates argued that batteries would never be able to power large semitrucks and that solar energy would not be a major part of solving the climate problem. “I showed him the numbers,” Gates says. “It’s an area where I clearly knew something that he didn’t.” He also gave Musk a hard time on Mars. “I’m not a Mars person,” Gates later told me. “He’s overboard on Mars. I let him explain his Mars thinking to me, which is kind of bizarre thinking. It’s this crazy thing where maybe there’s a nuclear war on Earth and so the people on Mars are there and they’ll come back down and, you know, be alive after we all kill each other.”
On dismissing climate philanthropy:
At the end of the tour, [Gates and Musk’s] conversation turned to philanthropy. Musk expressed his view that most of it was “bullshit.” There was only a twenty-cent impact for every dollar put in, he estimated. He could do more good for climate change by investing in Tesla.
On Bill Gates’ betrayal:
There was one contentious issue that [Bill Gates and Elon Musk] had to address. Gates had shorted Tesla stock, placing a big bet that it would go down in value […] Short-sellers occupied [Musk’s] innermost circle of hell. Gates said he was sorry, but that did not placate Musk. “I apologized to him,” Gates says. “Once he heard I’d shorted the stock, he was super mean to me, but he’s super mean to so many people, so you can’t take it too personally.”
[...] When I asked Gates why he had shorted Tesla, he explained that he had calculated that the supply of electric cars would get ahead of demand, causing prices to fall. I nodded but still had the same question: Why had he shorted the stock? Gates looked at me as if I had not understood what he just explained and then replied as if the answer was obvious: he thought that by shorting Tesla he could make money. That way of thinking was alien to Musk. He believed in the mission of moving the world to electric vehicles, and he put all of his available money toward that goal, even when it did not seem like a safe investment. “How can someone say they are passionate about fighting climate change and then do something that reduced the overall investment in the company doing the most?” he asked me a few days after Gates’s visit. “It’s pure hypocrisy. Why make money on the failure of a sustainable energy car company?”
On rejection:
Gates followed up in mid-April, sending Musk the promised paper on philanthropy options that he had personally written [...] “Sorry,” Musk shot back instantly. “I cannot take your philanthropy on climate seriously when you have a massive short position against Tesla, the company doing the most to solve climate change.” When angry, Musk can get mean, especially on Twitter. He tweeted a picture of Gates in a golf shirt with a bulging belly that made him look almost pregnant. “In case u need to lose a boner fast,” Musk’s comment read.

Half of all Americans are sweating under one right now.
Like a bomb cyclone, a polar vortex, or an atmospheric river, a heat dome is a meteorological phenomenon that feels, well, a little made up. I hadn’t heard the term before I found myself bottled beneath one in the Pacific Northwest in 2021, where I saw leaves and needles brown on living trees. Ultimately, some 1,400 people died from the extreme heat in British Columbia, Washington, and Oregon that summer weekend.
Since that disaster, there have been a number of other high-profile heat dome events in the United States, including this week, over the Midwest and now Eastern and Southeastern parts of the country. On Monday, roughly 150 million people — about half the nation’s population — faced extreme or major heat risks.
“I think the term ‘heat dome’ was used sparingly in the weather forecasting community from 10 to 30 years ago,” AccuWeather senior meteorologist Brett Anderson told me, speaking with 36 years as a forecaster under his belt. “But over the past 10 years, with global warming becoming much more focused in the public eye, we are seeing ‘heat dome’ being used much more frequently,” he went on. “I think it is a catchy term, and it gets the public’s attention.”
Catching the public’s attention is critical. Heat is the deadliest weather hazard in the U.S., killing more people annually than hurricanes, floods, tornadoes, or extreme cold. “There is a misunderstanding of the risk,” Ashley Ward, the director of the Heat Policy Innovation Hub at Duke University, told me. “A lot of people — particularly working age or younger people — don’t feel like they’re at risk when, in fact, they are.”
While it seems likely that the current heat dome won’t be as deadly as the one in 2021 — not least because the Midwest and Southeastern regions of the country have a much higher usage of air conditioning than the Pacific Northwest — the heat in the eastern half of the country is truly extraordinary. Tampa, Florida reached 100 degrees Fahrenheit on Sunday for the first time in its recorded history. Parts of the Midwest last week, where the heat dome formed before gradually moving eastward, hit a heat index of 128 degrees.
Worst of all, though, have been the accompanying record-breaking overnight temperatures, which Ward told me were the most lethal characteristics of a heat dome. “When there are both high daytime temperatures and persistently high overnight temperatures, those are the most dangerous of circumstances,” Ward said.
Although the widespread usage of the term “heat dome” may be relatively new, the phenomenon itself is not. The phrase describes an area of “unusually strong” high pressure situated in the upper atmosphere, which pockets abnormally warm air over a particular region, Anderson, the forecaster, told me. “These heat domes can be very expansive and can linger for days, and even a full week or longer,” he said.
Anderson added that while he hasn’t seen evidence of an increase in the number of heat domes due to climate change, “we may be seeing more extreme and longer-lasting heat domes” due to the warmer atmosphere. A heat dome in Europe this summer, which closed the Eiffel Tower, tipped temperatures over 115 degrees in parts of Spain, and killed an estimated 2,300 people, has been linked to anthropogenic warming. And research has borne out that the temperatures and duration reached in the 2021 Pacific Northwest heat dome would have been “virtually impossible without human-caused climate change.”
The link between climate change and heat domes is now strong enough to form the basis for a major legal case. Multnomah County, the Oregon municipality that includes Portland, filed a lawsuit in 2023 against 24 named defendants, including oil and gas companies ExxonMobil, Shell, and BP, seeking $50 million in damages and $1.5 billion in future damages for the defendants’ alleged role in the deaths from the 2021 heat dome.
“As we learned in this country when we took on Big Tobacco, this is not an easy step or one I take lightly, but I do believe it’s our best way to fight for our community and protect our future,” Multnomah County Chair Jessica Vega Pederson said in a statement at the time. The case is now in jeopardy following moves by the Trump administration to prevent states, counties, and cities from suing fossil fuel companies for climate damages. (The estate of a 65-year-old woman who died in the heat dome filed a similar wrongful death lawsuit in Seattle’s King County Superior Court against Big Oil.)
Given the likelihood of longer and hotter heat dome events, then, it becomes imperative to educate people about how to stay safe. As Ward mentioned, many people who are at risk of extreme heat might not even know it, such as those taking commonly prescribed medications for anxiety, depression, PTSD, diabetes, and high blood pressure, which interfere with the body’s ability to thermoregulate. “Let’s just say recently you started taking high blood pressure medicine,” Ward said. “Every summer prior, you never had a problem working in your garden or doing your lawn work. You might this year.”
Air conditioning, while life-saving, can also stop working for any number of reasons, from a worn out machine part to a widespread grid failure. Vulnerable community members may also face hurdles in accessing reliable AC. There’s a reason the majority of heat-related deaths happen indoors.
People who struggle to manage their energy costs should prioritize cooling a single space, such as a bedroom, and focus on maintaining a cool core temperature during overnight hours, when the body undergoes most of its recovery. Blotting yourself with a wet towel or washcloth and sitting in front of a fan can help during waking hours, as can visiting a traditional cooling center, or even a grocery store or movie theater.
Health providers also have a role to play, Ward stressed. “They know who has chronic underlying health conditions,” she said. “Normalize asking them about their situation with air conditioning. Normalize asking them, ‘Do you feel like you have a safe place to go that’s cool, that you can get out of this heat?’”
For the current heat dome, at least, the end is in sight: Incoming cool air from Canada will drop temperatures by 10 to 20 degrees in cities like Philadelphia and Washington, D.C., with lows potentially in the 30s by midweek in parts of New York. And while there are still hot days ahead for Florida and the rest of the Southeast, the cold front will reach the region by the end of the week.
But even if this ends up being the last heat dome of the summer, it certainly won’t be in our lifetimes. The heat dome has become inescapable.
On betrayed regulatory promises, copper ‘anxiety,’ and Mercedes’ stalled EV plans
Current conditions: New York City is once again choking on Canadian wildfire smoke • Torrential rain is flooding southeastern Slovenia and northern Croatia • Central Asia is bracing for the hottest days of the year, with temperatures nearing 100 degrees Fahrenheit in Uzbekistan’s capital of Tashkent all week.
In May, the Trump administration signaled its plans to gut Energy Star, the energy efficiency certification program administered by the Environmental Protection Agency. Energy Star is extremely popular — its brand is recognized by nearly 90% of Americans — and at a cost to the federal government of just $32 million per year, saves American households upward of $40 billion in energy costs per year as of 2024, for a total of more than $500 billion saved since its launch in 1992, by the EPA’s own estimate. Not only that, as one of Energy Star’s architects told Heatmap’s Jeva Lange back in May, more energy efficient appliances and buildings help reduce strain on the grid. “Think about the growing demands of data center computing and AI models,” RE Tech Advisors’ Deb Cloutier told Jeva. “We need to bring more energy onto the grid and make more space for it.”
That value has clearly resonated with lawmakers on the Hill. Legislators tasked with negotiating appropriations in both the Senate and the House of Representatives last week proposed fully funding Energy Star at $32 million for the next fiscal year. It’s unclear how the House’s decision to go into recess until September will affect the vote, but Ben Evans, the federal legislative director at the U.S. Green Building Council, said the bill is “a major step in the right direction demonstrating that ENERGY STAR has strong bipartisan support on Capitol Hill.”

The United States installed just under 11 gigawatts of solar panels in the first three months of this year, industry data show. In June alone, China installed nearly 15 gigawatts, PV Tech reported. And, in a detail that demonstrates just how many panels the People’s Republic has been deploying at home in recent years, that represented an 85% drop from the previous month and close to a 40% decline compared to June of last year.
The photovoltaic installation plunge followed Beijing’s rollout of two new policies that changed the renewables business in China. The first, called the 531 policy, undid guaranteed feed-in tariffs and required renewable projects to sell electricity on the spot market. That took effect on June 1. The other, called the 430 policy, took effect on May 1 and mandated that new distributed solar farms consume their own power first before allowing the sale of surplus electricity to the grid. As a result of the stalled installations, a top panel manufacturer warned the trade publication Opis that companies may need to raise prices by as much as 10%.
For years now, Fortescue, the world’s fourth-biggest producer of iron ore, has directed much of the earnings from its mines in northwest Australia and steel mills in China toward building out a global green hydrogen business. But changes to U.S. policy have taken a toll. Last week, Fortescue told investors it was canceling its green hydrogen project in Arizona, which had been set to come online next year. It’s also abandoning its plans for a green hydrogen plant on Australia’s northeastern coast, The Wall Street Journal reported.
“A shift in policy priorities away from green energy has changed the situation in the U.S.,” Gus Pichot, Fortescue’s chief executive of growth and energy, told analysts on a call. “The lack of certainty and a step back in green ambition has stopped the emerging green-energy markets, making it hard for previously feasible projects to proceed.” But green hydrogen isn’t dead everywhere. Just last week, the industrial gas firm Air Liquide made a final decision to invest in a 200-megawatt green hydrogen plant in the Netherlands.
The Trump administration put two high-ranking officials at the National Oceanic and Atmospheric Administration on administrative leave, CNN reported. The reasoning behind the move wasn’t clear, but both officials — Steve Volz, who leads NOAA’s satellites division, and Jeff Dillen, NOAA’s deputy general counsel — headed up the investigation into whether President Donald Trump violated NOAA’s scientific integrity policies during his so-called Sharpiegate scandal.
The incident from September 2019, during Trump’s first term, started when the president incorrectly listed Alabama among the states facing a threat from Hurricane Dorian. Throughout the following week, Trump defended the remark, insisting he had been right, and ultimately showed journalists a weather map that had been altered with a black Sharpie market to show the path of the storm striking Alabama. NOAA’s investigation into the incident concluded that Neil Jacobs, the former agency official who backed Trump at the time and is now nominated to serve as chief, succumbed to political pressure and violated scientific integrity rules.
In March, North Carolina’s Republican-controlled Senate passed a bill to repeal the state’s climate law and scrap the 2030 deadline by which the monopoly utility Duke Energy had to slash its planet-heating emissions by 70% compared to 2005 levels. Governor Josh Stein, a Democrat, vetoed the legislation. But on Tuesday, the GOP majorities in both chambers of the legislature plan to vote to override the veto.
Doing so and enacting the bill could cost North Carolina more than 50,000 jobs annually and cause tens of billions of dollars in lost investments, Canary Media’s Elizabeth Ouzts reported. That’s according to a new study from a consultancy commissioned by clean-energy advocates in the state. The analysis is based on data from the state-sanctioned consumer advocate, Public Staff.
For years, a mystery has puzzled scientists: Why did Neanderthal remains show levels of a nitrogen isotope only seen among carnivores like hyenas and wolves that eat more meat than a hominid could safely consume? New research finally points to an answer: Neanderthals were eating putrefying meat garnished with maggots, said Melanie Beasley, an anthropologist at Purdue University. “When you get the lean meat and the fatty maggot, you have a more complete nutrient that you’re consuming.”
Oregon’s Cram Fire was a warning — the Pacific Northwest is ready to ignite.
What could have been the country’s first designated megafire of 2025 spluttered to a quiet, unremarkable end this week. Even as national headlines warned over the weekend that central Oregon’s Cram Fire was approaching the 100,000-acre spread usually required to achieve that status, cooler, damper weather had already begun to move into the region. By the middle of the week, firefighters had managed to limit the Cram to 95,736 acres, and with mop-up operations well underway, crews began rotating out for rest or reassignment. The wildfire monitoring app Watch Duty issued what it said would be its final daily update on the Cram Fire on Thursday morning.
By this time in 2024, 10 megafires had already burned or ignited in the U.S., including the more-than-million-acre Smokehouse Creek fire in Texas last spring. While it may seem wrong to describe 2025 as a quieter fire season so far, given the catastrophic fires in the Los Angeles area at the start of the year, it is currently tracking below the 10-year average for acres burned at this point in the season. Even the Cram, a grassland fire that expanded rapidly due to the hot, dry conditions of central Oregon, was “not [an uncommon fire for] this time of year in the area,” Bill Queen, a public information officer with the Pacific Northwest Complex Incident Management Team 3, told me over email.
At the same time, the Cram Fire can also be read as a precursor. It was routine, maybe, but also large enough to require the deployment of nearly 900 fire personnel at a time when the National Wildland Fire Preparedness Level is set to 4, meaning national firefighting resources were already heavily committed when it broke out. (The preparedness scale, which describes how strapped federal resources are, goes up to 5.) Most ominous of all, though, is the forecast for the Pacific Northwest for “Dirty August” and “Snaptember,” historically the two worst months of the year in the region for wildfires.
National Interagency Coordination Center
“Right now, we’re in a little bit of a lull,” Jessica Neujahr, a public affairs officer with the Oregon Department of Forestry, acknowledged to me. “What comes with that is knowing that August and September will be difficult, so we’re now doing our best to make sure that our firefighters are taking advantage of having time to rest and get rejuvenated before the next big wave of fire comes through.”
That next big wave could happen any day. The National Interagency Fire Center’s fire potential outlook, last issued on July 1, describes “significant fire potential” for the Northwest that is “expected to remain above average areawide through September.” The reasons given include the fact that “nearly all areas” of Washington and Oregon are “abnormally dry or in drought status,” combined with a 40% to 60% probability of above-average temperatures through the start of the fall in both states. Moisture from the North American Monsoon, meanwhile, looks to be tracking “largely east of the Northwest.” At the same time, “live fuels in Oregon are green at mid to upper elevations but are drying rapidly across Washington.”
In other words, the components for a bad fire season are all there — the landscape just needs a spark. Lightning, in particular, has been top of mind for Oregon forecasters, given the tinderbox on the ground. A single storm system, such as one that rolled over southeast and east-central Oregon in June, can produce as many as 10,000 lightning strikes; over the course of just one night earlier this month, thunderstorms ignited 72 fires in two southwest Oregon counties. And the “kicker with lightning is that the fires don’t always pop up right away,” Neujahr explained. Instead, lightning strike fires can simmer for up to a week after a storm, evading the detection of firefighting crews until it’s too late. “When you have thousands of strikes in a concentrated area, it’s bound to stretch the local resources as far as they can go,” Neujahr said.
National Interagency Coordination Center
The National Interagency Fire Center has “low confidence … regarding the number of lightning ignitions” for the end of summer in the Northwest, in large part due to the incredible difficulty of forecasting convective storms. Additionally, the current neutral phase of the El Niño-Southern Oscillation means there is a “wide range of potential lightning activity” that adds extra uncertainty to any predictions. The NIFC’s higher confidence in its temperature and precipitation outlooks, in turn, “leads to a belief that the ratio of human to natural ignitions will remain high and at or above 2024 levels.” (An exploding transformer appears to have been the ignition source for the Cram Fire; approximately 88% of wildfires in the United States have human-caused origins, including arson.)
Periodic wildfires are a naturally occurring part of the Western ecosystem, and not all are attributable to climate change. But before 1995, the U.S. averaged fewer than one megafire per year; between 2005 and 2014, that average jumped to 9.8 such fires per year. Before 1970, there had been no documented megafires at all.
Above-average temperatures and drought conditions, which can make fires larger and burn hotter, are strongly associated with a warming atmosphere, however. Larger and hotter fires are also more dangerous. “Our biggest goal is always to put the fires out as fast as possible,” Neujahr told me. “There is a correlation: As fires get bigger, the cost of the fire grows, but so do the risks to the firefighters.”
In Oregon, anyway, the Cram Fire’s warning has registered. Shortly after the fire broke out, Oregon Governor Tina Kotek declared a statewide emergency with an eye toward the months ahead. “The summer is only getting hotter, drier, and more dangerous — we have to be prepared for worsening conditions,” she said in a statement at the time.
It’s improbable that there won’t be a megafire this season; the last time the U.S. had a year without a fire of 100,000 acres or more was in 2001. And if or when the megafire — or megafires — break out, all signs point to the “where” being Oregon or Washington, concentrating the area of potential destruction, exhausting local personnel, and straining federal resources. “When you have two states directly next to each other dealing with the same thing, it just makes it more difficult to get resources because of the conflicting timelines,” Neujahr said.
By October, at least, there should be relief: The national fire outlook describes “an increasing frequency of weather systems and precipitation” that should “signal an end of fire season” for the Northwest once fall arrives. But there are still a long 68 days left to go before then.
