“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.

And more on the week’s biggest conflicts around renewable energy projects.
1. Jackson County, Kansas – A judge has rejected a Hail Mary lawsuit to kill a single solar farm over it benefiting from the Inflation Reduction Act, siding with arguments from a somewhat unexpected source — the Trump administration’s Justice Department — which argued that projects qualifying for tax credits do not require federal environmental reviews.
2. Portage County, Wisconsin – The largest solar project in the Badger State is now one step closer to construction after settling with environmentalists concerned about impacts to the Greater Prairie Chicken, an imperiled bird species beloved in wildlife conservation circles.
3. Imperial County, California – The board of directors for the agriculture-saturated Imperial Irrigation District in southern California has approved a resolution opposing solar projects on farmland.
4. New England – Offshore wind opponents are starting to win big in state negotiations with developers, as officials once committed to the energy sources delay final decisions on maintaining contracts.
5. Barren County, Kentucky – Remember the National Park fighting the solar farm? We may see a resolution to that conflict later this month.
6. Washington County, Arkansas – It seems that RES’ efforts to build a wind farm here are leading the county to face calls for a blanket moratorium.
7. Westchester County, New York – Yet another resort town in New York may be saying “no” to battery storage over fire risks.
Solar and wind projects are getting swept up in the blowback to data center construction, presenting a risk to renewable energy companies who are hoping to ride the rise of AI in an otherwise difficult moment for the industry.
The American data center boom is going to demand an enormous amount of electricity and renewables developers believe much of it will come from solar and wind. But while these types of energy generation may be more easily constructed than, say, a fossil power plant, it doesn’t necessarily mean a connection to a data center will make a renewable project more popular. Not to mention data centers in rural areas face complaints that overlap with prominent arguments against solar and wind – like noise and impacts to water and farmland – which is leading to unfavorable outcomes for renewable energy developers more broadly when a community turns against a data center.
“This is something that we’re just starting to see,” said Matthew Eisenson, a senior fellow with the Renewable Energy Legal Defense Initiative at the Columbia University Sabin Center for Climate Change Law. “It’s one thing for environmentalists to support wind and solar projects if the idea is that those projects will eventually replace coal power plants. But it’s another thing if those projects are purely being built to meet incremental demand from data centers.”
We’ve started to see evidence of this backlash in certain resort towns fearful of a new tech industry presence and the conflicts over transmission lines in Maryland. But it is most prominent in Virginia, ground zero for American hyperscaler data centers. As we’ve previously discussed in The Fight, rural Virginia is increasingly one of the hardest places to get approval for a solar farm in the U.S., and while there are many reasons the industry is facing issues there, a significant one is the state’s data center boom.
I spent weeks digging into the example of Mecklenburg County, where the local Board of Supervisors in May indefinitely banned new solar projects and is rejecting those that were in the middle of permitting when the decision came down. It’s also the site of a growing data center footprint. Microsoft, which already had a base of operations in the county’s town of Boydton, is in the process of building a giant data center hub with three buildings and an enormous amount of energy demand. It’s this sudden buildup of tech industry infrastructure that is by all appearances driving a backlash to renewable energy in the county, a place that already had a pre-existing high opposition risk in the Heatmap Pro database.
It’s not just data centers causing the ban in Mecklenburg, but it’s worth paying attention to how the fight over Big Tech and solar has overlapped in the county, where Sierra Club’s Virginia Chapter has worked locally to fight data center growth with a grassroots citizens group, Friends of the Meherrin River, that was a key supporter of the solar moratorium, too.
In a conversation with me this week, Tim Cywinski, communications director for the state’s Sierra Club chapter, told me municipal leaders like those in Mecklenburg are starting to group together renewables and data centers because, simply put, rural communities enter into conversations with these outsider business segments with a heavy dose of skepticism. This distrust can then be compounded when errors are made, such as when one utility-scale solar farm – Geenex’s Grasshopper project – apparently polluted a nearby creek after soil erosion issues during construction, a problem project operator Dominion Energy later acknowledged and has continued to be a pain point for renewables developers in the county.
“I don’t think the planning that has been presented to rural America has been adequate enough,” the Richmond-based advocate said. “Has solar kind of messed up in a lot of areas in rural America? Yeah, and that’s given those communities an excuse to roll them in with a lot of other bad stuff.”
Cywinski – who describes himself as “not your typical environmentalist” – says the data center space has done a worse job at community engagement than renewables developers in Virginia, and that the opposition against data center projects in places like Chesapeake and Fauquier is more intense, widespread, and popular than the opposition to renewables he’s seeing play out across the Commonwealth.
But, he added, he doesn’t believe the fight against data centers is “mutually exclusive” from conflicts over solar. “I’m not going to tout the gospel of solar while I’m trying to fight a data center for these people because it’s about listening to them, hearing their concerns, and then not telling them what to say but trying to help them elevate their perspective and their concerns,” Cywinski said.
As someone who spends a lot of time speaking with communities resisting solar and trying to best understand their concerns, I agree with Cywinksi: the conflict over data centers speaks to the heart of the rural vs. renewables divide, and it offers a warning shot to anyone thinking AI will help make solar and wind more popular.
The One Big Beautiful Bill Act is one signature away from becoming law and drastically changing the economics of renewables development in the U.S. That doesn’t mean decarbonization is over, experts told Heatmap, but it certainly doesn’t help.
What do we do now?
That’s the question people across the climate change and clean energy communities are asking themselves now that Congress has passed the One Big Beautiful Bill Act, which would slash most of the tax credits and subsidies for clean energy established under the Inflation Reduction Act.
Preliminary data from Princeton University’s REPEAT Project (led by Heatmap contributor Jesse Jenkins) forecasts that said bill will have a dramatic effect on the deployment of clean energy in the U.S., including reducing new solar and wind capacity additions by almost over 40 gigawatts over the next five years, and by about 300 gigawatts over the next 10. That would be enough to power 150 of Meta’s largest planned data centers by 2035.
But clean energy development will hardly grind to a halt. While much of the bill’s implementation is in question, the bill as written allows for several more years of tax credit eligibility for wind and solar projects and another year to qualify for them by starting construction. Nuclear, geothermal, and batteries can claim tax credits into the 2030s.
Shares in NextEra, which has one of the largest clean energy development businesses, have risen slightly this year and are down just 6% since the 2024 election. Shares in First Solar, the American solar manufacturer, are up substantially Thursday from a day prior and are about flat for the year, which may be a sign of investors’ belief that buyer demand for solar panels will persist — or optimism that the OBBBA’s punishing foreign entity of concern requirements will drive developers into the company’s arms.
Partisan reversals are hardly new to climate policy. The first Trump administration gleefully pulled the rug from under the Obama administration’s power plant emissions rules, and the second has been thorough so far in its assault on Biden’s attempt to replace them, along with tailpipe emissions standards and mileage standards for vehicles, and of course, the IRA.
Even so, there are ways the U.S. can reduce the volatility for businesses that are caught in the undertow. “Over the past 10 to 20 years, climate advocates have focused very heavily on D.C. as the driver of climate action and, to a lesser extent, California as a back-stop,” Hannah Safford, who was director for transportation and resilience in the Biden White House and is now associate director of climate and environment at the Federation of American Scientists, told Heatmap. “Pursuing a top down approach — some of that has worked, a lot of it hasn’t.”
In today’s environment, especially, where recognition of the need for action on climate change is so politically one-sided, it “makes sense for subnational, non-regulatory forces and market forces to drive progress,” Safford said. As an example, she pointed to the fall in emissions from the power sector since the late 2000s, despite no power plant emissions rule ever actually being in force.
“That tells you something about the capacity to deliver progress on outcomes you want,” she said.
Still, industry groups worry that after the wild swing between the 2022 IRA and the 2025 OBBA, the U.S. has done permanent damage to its reputation as a business-friendly environment. Since continued swings at the federal level may be inevitable, building back that trust and creating certainty is “about finding ballasts,” Harry Godfrey, the managing director for Advanced Energy United’s federal priorities team, told Heatmap.
The first ballast groups like AEU will be looking to shore up is state policy. “States have to step up and take a leadership role,” he said, particularly in the areas that were gutted by Trump’s tax bill — residential energy efficiency and electrification, transportation and electric vehicles, and transmission.
State support could come in the form of tax credits, but that’s not the only tool that would create more certainty for businesses — considering the budget cuts states will face as a result of Trump’s tax bill, it also might not be an option. But a lot can be accomplished through legislative action, executive action, regulatory reform, and utility ratemaking, Godfrey said. He cited new virtual power plant pilot programs in Virginia and Colorado, which will require further regulatory work to “to get that market right.”
A lot of work can be done within states, as well, to make their deployment of clean energy more efficient and faster. Tyler Norris, a fellow at Duke University's Nicholas School of the Environment, pointed to Texas’ “connect and manage” model for connecting renewables to the grid, which allows projects to come online much more quickly than in the rest of the country. That’s because the state’s electricity market, ERCOT, does a much more limited study of what grid upgrades are needed to connect a project to the grid, and is generally more tolerant of curtailing generation (i.e. not letting power get to the grid at certain times) than other markets.
“As Texas continues to outpace other markets in generator and load interconnections, even in the absence of renewable tax credits, it seems increasingly plausible that developers and policymakers may conclude that deeper reform is needed to the non-ERCOT electricity markets,” Norris told Heatmap in an email.
At the federal level, there’s still a chance for, yes, bipartisan permitting reform, which could accelerate the buildout of all kinds of energy projects by shortening their development timelines and helping bring down costs, Xan Fishman, senior managing director of the energy program at the Bipartisan Policy Center, told Heatmap. “Whether you care about energy and costs and affordability and reliability or you care about emissions, the next priority should be permitting reform,” he said.
And Godfrey hasn’t given up on tax credits as a viable tool at the federal level, either. “If you told me in mid-November what this bill would look like today, while I’d still be like, Ugh, that hurts, and that hurts, and that hurts, I would say I would have expected more rollbacks. I would have expected deeper cuts,” he told Heatmap. Ultimately, many of the Inflation Reduction Act’s tax credits will stick around in some form, although we’ve yet to see how hard the new foreign sourcing requirements will hit prospective projects.
While many observers ruefully predicted that the letter-writing moderate Republicans in the House and Senate would fold and support whatever their respective majorities came up with — which they did, with the sole exception of Pennsylvania Republican Brian Fitzpatrick — the bill also evolved over time with input from those in the GOP who are not openly hostile to the clean energy industry.
“You are already seeing people take real risk on the Republican side pushing for clean energy,” Safford said, pointing to Alaska Republican Senator Lisa Murkowski, who opposed the new excise tax on wind and solar added to the Senate bill, which earned her vote after it was removed.
Some damage has already been done, however. Canceled clean energy investments adds up to $23 billion so far this year, compared to just $3 billion in all of 2024, according to the decarbonization think tank RMI. And that’s before OBBBA hits Trump’s desk.
The start-and-stop nature of the Inflation Reduction Act may lead some companies, states, local government and nonprofits to become leery of engaging with a big federal government climate policy again.
“People are going to be nervous about it for sure,” Safford said. “The climate policy of the future has to be polycentric. Even if you have the political opportunity to make a big swing again, people will be pretty gun shy. You will need to pursue a polycentric approach.”
But to Godfrey, all the back and forth over the tax credits, plus the fact that Republicans stood up to defend them in the 11th hour, indicates that there is a broader bipartisan consensus emerging around using them as a tool for certain energy and domestic manufacturing goals. A future administration should think about refinements that will create more enduring policy but not set out in a totally new direction, he said.
Albert Gore, the executive director of the Zero Emissions Transportation Association, was similarly optimistic that tax credits or similar incentives could work again in the future — especially as more people gain experience with electric vehicles, batteries, and other advanced clean energy technologies in their daily lives. “The question is, how do you generate sufficient political will to implement that and defend it?” he told Heatmap. “And that depends on how big of an economic impact does it have, and what does it mean to the American people?”
Ultimately, Fishman said, the subsidy on-off switch is the risk that comes with doing major policy on a strictly partisan basis.
“There was a lot of value in these 10-year timelines [for tax credits in the IRA] in terms of business certainty, instead of one- or two- year extensions,” Fishman told Heatmap. “The downside that came with that is that it became affiliated with one party. It was seen as a partisan effort, and it took something that was bipartisan and put a partisan sheen on it.”
The fight for tax credits may also not be over yet. Before passage of the IRA, tax credits for wind and solar were often extended in a herky-jerky bipartisan fashion, where Democrats who supported clean energy in general and Republicans who supported it in their districts could team up to extend them.
“You can see a world where we have more action on clean energy tax credits to enhance, extend and expand them in a future congress,” Fishman told Heatmap. “The starting point for Republican leadership, it seemed, was completely eliminating the tax credits in this bill. That’s not what they ended up doing.”
