Embarrassed to be driving a Tesla these days? You’re not alone.

Tesla is ubiquitous. Following Election Day, the company’s shares broke the $1 trillion mark, making the electric vehicle manufacturer more valuable than the next 15 automakers combined. Much of that is because Elon Musk’s company is likely to benefit from its CEO having President-elect Donald Trump’s ear. But it’s also because Teslas are good EVs — the Model Y is one of Heatmap’s top picks for someone who wants to make a stress-free switch away from gasoline.
The problem is, well, Elon. Though 35% of respondents to a Heatmap poll last winter said the controversial and erratic executive made them more likely to want to purchase a Tesla, there are plenty of people who wouldn’t be caught dead in an EV that in any way benefits the newly minted government efficiency crusader.
But what about all those people who purchased Teslas before Musk went full MAGA? For them, there’s a solution in the form of bumper stickers produced by Matthew Hiller of Waikiki, Hawaii. Hiller’s side hustle, Mad Puffer Stickers, gives Tesla owners a way to disavow the company’s CEO in the form of a no Elon sticker, an Anti-Elon Tesla Club sticker, or one that spells it all out: “I bought this before we knew Elon was crazy.” As you might expect, business is booming.
Last night, I caught up with Hiller about his unexpected success. Our conversation has been edited and condensed for clarity.
How did you begin making anti-Elon Musk stickers?
I started making stickers on my own before the Elon sticker. I work at an aquarium, so I did a lot of fish stickers. I always had an interest in making stickers — I knew how to make them, and how to put the designs and cute phrases on them.
The point came in maybe February or January of 2023. I had been wanting to buy a Tesla, but at that point, I started to notice how far off the rails Elon had been going. When he bought Twitter, he started extreme censoring of information, taking verification marks off The New York Times and things like that to sow discontent, disinformation, and push his agenda. And it was ugly. I couldn’t believe this man was using his power like this, and I immediately did not want to support him in any way. I figured, there’s no way I’m buying a Tesla — but there have got to be so many people who are so embarrassed to be repping him on the streets driving their Teslas and who want to completely disavow this guy. Because I know I would want to sell mine immediately after I saw what he was doing.
So I made the first sticker, which said, “I bought this before we knew Elon was crazy.” I printed up a very small run at first and just threw it in my shop. It took a while for the first sale, but after it got rolling, some people started posting pictures. It went viral a couple of times and I would see a burst of sales, and then it would quiet down. I would be selling five to seven a day, and then suddenly, there would be 50 a day because someone else talked about it on Reddit.
And now, at this point, it’s gone insane.
Have your sales gone up since the election?
Absolutely. Unbelievably.
There were major points when the sales spiked beyond anything that had happened before. The first time was when Elon went on stage with Trump at one of the rallies, and that solidified what everybody already knew: that he was in the tank for Trump, and he was going to put his full fortune behind getting the guy elected.
Then after the election, there was another huge bunch of sales because people were like, “Oh my God, this guy is now going to have a part in this government.” This was so in-your-face and so disgusting — he’s just filling Trump’s coffers with his money in exchange for position and power and influence. And it showed in the sales that other people thought so, too: I must have sold probably 250 or 300 that day, and it’s been steady ever since. I can barely keep up. My full-time job is at the aquarium, and I come home and pack stickers until 11 p.m. It’s just me and my wife doing it all.
Can you give me a ballpark of how many you’ve sold?
Definitely over 10,000. I think today we’re at about 180 [per day] — and that’s across all my stickers, not just the anti-Elon sticker. But it’s been around 100-plus every day for weeks now. It’s rough.
Which is the most popular design?
The most popular is the OG, the “I bought this before we knew Elon was crazy.” It’s the only one that I have that is a traditional long bumper sticker, rectangular. And I’m a little upset that it’s the most popular because it’s the hardest one to ship because of the odd-size envelopes. For all the other ones, it’s easier. But that’s the most popular one by far.
It’s currently the No. 4 best-selling bumper sticker on Amazon. It had been #1 at a few different points. At one point it was beating both Trump and Kamala stickers. And I was like, “That’s insane. People hate Elon more than they love Trump or Kamala?”
Have you sold to any Cybertruck owners, as far as you’re aware?
I have no idea. I don’t think so — I mean, everyone knew he was crazy by the time the Cybertruck came out. People buying the Cybertruck are all in.
I saw on Instagram that you dropped off some stickers at a Tesla dealership?
That was a while ago. I didn’t take stickers; I believe I had a key chain at that point. I dropped them around the store just for the heck of it, to try to drum up some interest in anti-Elon sentiment. Maybe it’d find the right person, you never know. I wish I had more time to focus on social media, but I just don’t.
Do you have any more anti-Elon sticker design plans?
There’s one that’s a little more general, and it just says, “No more billionaires.” Elon is the main problem: He’s probably the worst billionaire, but he’s not the only problem. So maybe that sticker will end up on a Tesla, too.
Will you keep making your fish stickers now that your anti-Elon business has taken off?
Yeah. I have the ideas banked, I just don’t bother printing them at this point. There’s no point — I’m swamped with what I’ve got. But yeah, absolutely. If I have a really good one, I’ll print it for the aquarium, but not my own personal store. At this point, I’m all Elon, all the time.

This year’s ocean-heating phenomenon could make climate change seem less bad than it really is — at least in the U.S.
You may have heard that we could be in for a “super” or even a “super duper” El Niño this year. The difference is non-technical, a matter of how warm the sea surface temperature in the El Niño-Southern Oscillation region of the central-eastern Pacific Ocean gets. An El Niño forms when the region is at least half a degree Celsius warmer than average, which causes more heat to be released into the atmosphere and affects global weather patterns. A super El Niño describes an anomaly of 2 degrees or higher. Some models predict an anomaly of over 3 degrees higher than average for this year.
If a super El Niño forms — and that is still a big if, about a one-in-four chance — it would be the fourth such event in just over 40 years. But the impacts could be even more severe, simply because the world is hotter today than it was in the previous super El Niño years of 1983, 1998, and 2016.
“2016 would be an unusually cold year if it occurred today,” Zeke Hausfather, the climate research lead for payment processing giant Stripe and a research scientist at Berkeley Earth, told me. “1998 would be exceptionally cold.”
And yet in a strange twist, a 2026-2027 El Niño event might actually make Americans care less about climate change. Though many parts of the world are likely to get clobbered by El Niño’s characteristic combination of hotter, drier weather, the phenomenon has the potential to alleviate some of the extreme weather we’ve seen recently in the United States.
For example, warmer, wetter conditions in the southern U.S., milder winters in the north, and increased wind shear in the Atlantic hurricane basin are all classic El Niño signatures in North America.
“It may actually mean a better snow season for the Western U.S. and the mountains, hopefully recovering our snowpack if it’s not too warm,” Hausfather said. “We might benefit from higher rainfall” next winter, which could help lift widespread drought conditions in the southwest. High wind shear usually results in reduced hurricane activity in the Atlantic by depriving the storm systems of their heat engines and causing them to be too lopsided to organize into a full-blown cyclone.
Though the body of evidence for climate change remains incontrovertible, the temporary reprieve in some of its more visible effects will almost certainly make some Americans less concerned. Blame it on evolutionary biology. Brett Pelham, a social psychologist at Montgomery College who researches egocentrism and biases, told me that humans are hardwired to pay attention to the conditions happening directly around them. “That’s great if you’re living 20,000 or 80,000 years ago,” he said. “But today, we’re pumping tons of greenhouse gases into the atmosphere, and it’s a recipe for disaster because people only care deeply about that problem if they feel the heat on a pretty chronic basis where they live.”
People are generally less likely to believe the planet is warming on a snowy day in March than they are in the summer, and a lower average state temperature is about as reliable a predictor of climate change skepticism as being a Republican, even when controlling for income, party affiliation, education, and age. Given that it is, in theory, easier to convince someone living in scorching hot Phoenix that greenhouse gases are warming the atmosphere than someone living by a lake in Minnesota, if an El Niño mellows out some extreme weather trends in the U.S. this year and next, it could also mellow some of the sense of urgency to act.
“It’s a definite implication of my work that day-to-day variation, monthly variation, and geographical variation matter,” Pelham said.
“If my data are true,” he added, “it’s going to be true on average that in places that have an unseasonably cool summer or winter, there’s going to be a temporary shift in the average attitude.”
Such shifts affect the average by just a few points either way — “they’re not night and day, like ‘I believed in climate change and now I don’t,’” Pelham stressed. But it’s undoubtedly ironic — and concerning — that heading into what could be one of the hottest years on the planet in recent history, Americans may be predisposed to feeling relatively safe.
Other parts of the world won’t have such luxury. Even a normal-strength El Niño, which looks all but certain to form this year, could cause major damage, from wildfires in parched Indonesia to catastrophic floods in East Africa to water rationing in South America. In Peru and Ecuador, El Niño is already a “current event,” Ángel F. Adames Corraliza, an atmospheric researcher at the University of Wisconsin-Madison and a 2025 MacArthur Fellow, told me. Warm coastal conditions off the continent — a known, albeit not guaranteed, global El Niño precursor — are causing deluges, landslides, and heat waves in the upper northwest corner of South America. “You can see how the impacts start extending towards other parts of the world until it reaches us,” he said.
It is possible to combat local biases. Pelham told me other researchers have found that images can break through our egocentrism. So “if we see more pictures of melting glaciers or waters rising in our own backyards, we would start to say, ‘Oh my goodness, we really have to do something about this global problem,” he said.
But to that end, coverage of climate change that might have this effect is becoming rarer. Stories about global warming have dropped about 38% since 2021; even people working in climate-related industries have “a kind of exhaustion with ‘climate’ as the right frame through which to understand the fractious mixture of electrification, pollution reduction, clean energy development, and other goals that people who care about climate change actually pursue,” my colleague Robinson Meyer wrote based on the results of latest Heatmap Insiders Survey.
Of course, there is no promise that the U.S. will skirt disaster because of El Niño. Increased rainfall means more floods and landslides; if the El Niño pushes temperatures up too high, snowpack will once again be an issue next winter. All it takes is one big hurricane forming and making landfall for it to be considered a bad storm year, which is as much a roll of the dice as anything else. And because El Niño releases ocean heat into the atmosphere, the periods immediately following it are often about two-tenths of a degree Celsius warmer, increasing the severity of heat waves and droughts. Compounded by climate change, that puts 2027 on track to be potentially the hottest year the planet has seen in human history.
“We might be at 1.45 degrees Celsius [above preindustrial levels] next year from human activity, and we might end up at 1.65 degrees because there’s a very strong El Niño,” Hausfather said. But for context, “we are seeing that much warmth added to the climate system from human activity roughly every decade,” he told me. That is, “— we’re adding a permanent super El Niño-worth of heat to the climate system” via the continued burning of fossil fuels.
There couldn’t be a worse time to let up on our collective sense of climate urgency, to put it mildly. But if El Niño makes conditions in the U.S. appear any better, then even if there’s disaster elsewhere, “you’re going to give a sigh of relief,” Pelham predicted. “You’re going to feel like [climate change is] not as bad as people have hyped it up to be.”
Current conditions: Wildfires are raging across the Southeast, with more than 27,000 acres alight in southern Georgia alone • At least two separate blazes have also broken out in Japan’s northeastern Iwate prefecture • A late blizzard is dumping as much as 20 inches of snow on northern Manitoba, Canada.
Yet another French energy giant is lining up for a payout from the Trump administration to abandon its offshore wind projects in the United States. Utility giant Engie is in talks with the federal government about a “possible refund” for its U.S. offshore wind leases as President Donald Trump looks to halt expansion of an energy source that’s quickly growing in Europe and Asia. Since Trump returned to office last year, the company has paused development on three offshore wind projects and already took a loss on its joint venture Ocean Winds. In an interview with Reuters, Engie CEO Catherine MacGregor confirmed that the utility was pursuing the kind of deal that French oil and gas giant TotalEnergies negotiated in recent weeks. “We’ll see about these terms. An agreement is possible depending on the discussions.” She noted that she wasn’t against offshore wind. “Economically and also in terms of public acceptance, I strongly believe in offshore wind power. Of course, you have to plan the projects well, you have to involve the fishermen,” she added. Still, “new offshore wind projects are going to be complicated regardless of the administration.”
The $1 billion TotalEnergies deal may also stand on shaky ground. As Heatmap’s Emily Pontecorvo reported in back-to-back scoops, documents suggest the Trump administration’s legal argument for drawing on a federal settlement fund rests on shaky ground. Other documents show that TotalEnergies isn't required to make any new investments in U.S. oil and gas under the agreement, contrary to what Trump officials said about the deal.

Long accused of maintaining an overcapacity of factories to churn out solar panels, China’s photovoltaic output is now in soaring demand as the world scrambles to cope with the energy shock brought on by the Iran War’s closure of the Strait of Hormuz. New data from the think tank Ember shows that China’s solar exports reached a record 68 gigawatts in March, double the previous month. When Ember analyzed the Chinese customs authority data, its researchers found that the exports are equivalent to Spain’s entire solar capacity, surpassing the previous record set in August 2025 by 49%. At least 50 countries — you read that right — set all-time records for Chinese solar imports in March, with another 60 seeing the highest levels in six months. Compared to February numbers (the war began on February 28), Chinese solar exports grew by 141% to India, 384% to Malaysia, 391% to Ethiopia, and 519% to Nigeria.
“Fossil shocks are boosting the solar surge,” Euan Graham, senior analyst at Ember, said in a statement. “Solar has already become the engine of the global economy, and now the current fossil fuel price shocks are taking it up a gear. Countries are importing solar panels at record levels, and building up their own domestic assembly and manufacturing capabilities to address surging global demand.”
Elon Musk is betting even bigger on artificial intelligence. Tesla plans to boost spending to $25 billion this year as the electric automaker cum battery and solar giant invests in self-driving taxis, zero-emissions trucks, robots, and a sweeping new chip factory to power its AI ambitions. During a call with investors on Thursday, Musk said there would be a “very significant increase in capital expenditure” this year, which “will be well justified considering substantially increased revenue streams,” according to the Financial Times. The forecast is nearly triple the $8.5 billion Tesla spent last year.
The shift comes as the U.S. faces what Heatmap contributor Andrew Moseman called the “great American EV contraction” that took place after the Trump administration ended federal tax credits for electric vehicles last fall.

In a nuclear industry filled with startups promising to reinvent the reactor, Blue Energy stands out as a company promising instead to transform how good old-fashioned light water reactors are built. The firm wants to prefabricate its small modular reactors in a factory, making each one as uniform and replicable as possible. “For the first time, a nuclear project is designed so that it doesn’t need to rely primarily on taxpayer dollars and ratepayers to backstop risk,” Jake Jurewicz, Blue Energy chief executive and co-founder, told S&P Global. In a press release, Jurewicz called its forthcoming debut facility, a 1.5-gigawatt complex in Texas, “the first project-financeable nuclear plant.”
Shares in GE Vernova spiked 14% on Wednesday after the energy industrial giant reported surging demand for its gas turbines and nuclear reactors to power the AI boom in its latest quarterly earnings. As I told you yesterday, GE Vernova’s head of government affairs and policy, Roger Martella, said this week that the project to build North America’s first small modular reactor at Ontario Power Generation’s Darlington plant was on track to produce power by 2030. In a note to investors, the investment bank Jeffries said soaring gas demand and “green-shoots for nuclear” sent the price upward.
If online gambling services like Kalshi and Polymarket allow people to bet on something, do the incentives for the worse outcome change? Turns out, obviously, the answer is yes. Just consider this example. Polymarket allowed people to bet on daily temperatures from some official weather stations. Now Météo-France, the official French meteorological agency, is accusing someone of using an artificial heat source to manipulate reads at a station and win bets.
Rob dives into Fervo’s S-1 filing with Princeton professor Jesse Jenkins and Heatmap’s Matthew Zeitlin.
Fervo Energy has become a darling of the clean energy industry by using workers and technology from the oil and gas sector to unlock zero-carbon, all-day geothermal electricity. Last week, Fervo filed to go public, giving us the first deep look at its finances and long-term expansion plans. What’s the bull case, the bear case, and the fine print?
On this week’s episode of Shift Key, Rob is joined by Jesse Jenkins, a professor of energy systems engineering at Princeton University, as well as Heatmap’s Matthew Zeitlin to discuss the big news from Fervo’s new filing. Why are people so excited about Fervo? What are the biggest financial questions in its growth plans? And why does it need to go public now?
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap News.

Here is an excerpt of their conversation:
Robinson Meyer: Jesse, one of the things that people are most excited about with Fervo — and one of the things, frankly, that you got me excited about with regard to Fervo and other enhanced geothermal companies — is that this is dispatchable power. It’s not only that it’s 24-7, but much like like we currently flex gas plants up or down to meet demand on the grid, we might be able to flex geothermal plants up and down. Can you just describe like how that would work and why it’s important to kind of overall value of this energy technology?
Jesse Jenkins: Yeah, so most people think of geothermal as a kind of zero marginal cost resource. It has no fuel cost, right? It’s producing power that’s on the margin, basically free. And so it would make sense to operate it like a “baseload resource” running 24-7, because why would you ever turn off?
The reality is that if you are deploying geothermal in a world with lots of cheap solar, for example, or wind in other parts of the West, there are many hours when power is literally worthless or very inexpensive, right? You’ve got wind and solar flooding the market at also zero marginal cost. And so producing power in those hours, you can do it, but why would you? It’s not valuable. When it’s valuable is the times when the sun is setting and the wind is dying down and you would otherwise have to fire up gas power plants.
So one of the cool things about enhanced geothermal is that you’re basically engineering a fracture network inside a very impermeable rock, right? You basically have a container around it of granite. And that means that very little fluid or pressure will leak out of the reservoir if you inject more fluid into it. And so you’ve basically built yourself a pumped hydrate reservoir underground for free, because that’s what you needed to create your heat exchanger to get the heat out for your power plant.
