On affordable EVs, the future of NOAA, and tropical birds
Current conditions: Several wildfires are burning near parts of North Carolina that were devastated by Hurricane Helene • Public transportation in Bangkok is free this week as authorities try to reduce toxic smog • There is ice on the surface of the Potomac River near Reagan National Airport, where recovery operations are underway following a tragic plane crash last night.
Tesla reported disappointing Q4 results for 2024 yesterday, with revenue and earnings per share both missing analysts expectations. Revenue came in at $25.71 billion, down 8% compared to the same period in 2023. Earnings per share were $0.73, compared to projections of $0.77. Gross profit margin fell to 13.6% year-over-year, less than the 16.2% forecast. Tesla’s stock dipped on the news, but rebounded after CEO Elon Musk tried to make some reassurances during the earnings call. He said Tesla planned to launch a driverless ride-hailing service in Austin, Texas, in June, and expects to begin producing the Cybercab robotaxi fleet in 2026. He talked up the Optimus humanoid robot and the company’s AI and robotics investments. And he said the company plans to start producing “more affordable models” of its EVs in the first half of 2025. (Worth noting that the Cybertruck was not mentioned once on the call.)
If Musk was at all concerned about the fact that his company saw annual sales drop last year for the first time in more than a decade, he didn’t show it, predicting that the next few years will be “epic” for the company. “I see a path for Tesla being the most valuable company in the world, by far, not even close,” he said. “There is a path where Tesla is worth more than the next top five companies combined.”
The pep talk helped boost shares in pre-market trading. Some analysts were raving. “Tesla investors are fuelled by optimism around Full Self-Driving and the upcoming affordable model, two key catalysts that could drive Tesla’s next leg of growth,” said Hargreaves Lansdown’s Matt Britzman. Others were less optimistic. “While the long-term narrative remains, the fourth-quarter was a ‘back to earth’ moment for Tesla stock, which has increasingly been disconnected from fundamentals,” cautioned Barclays analyst Dan Levy.
Lee Zeldin was confirmed yesterday as the new administrator of the Environmental Protection Agency. He has promised to “restore U.S. energy dominance” and “increase productivity of the EPA.” One of his first jobs, though, will be reviewing the 2009 endangerment finding, a landmark ruling that confirmed greenhouse gases are a danger to public health and gave the EPA authority to regulate those gases. President Trump signed an executive order on January 20 giving the EPA 30 days to examine the “legality and continuing applicability” of this finding. Zeldin has also been told to review the social cost of carbon, which is “the cost of the damages created by one extra ton of carbon dioxide emissions.” Trump’s executive order recommended the metric be eliminated altogether.
Meanwhile, Trump’s Commerce secretary nominee Howard Lutnick had his confirmation hearings yesterday. The questioning from senators touched on the future of the National Oceanic and Atmospheric Administration, the agency that provides national weather forecasting and climate monitoring. Lutnick said he was not in favor of dismantling NOAA, nor would he want to see it moved from the Commerce Department into the Interior Department. The Project 2025 roadmap from the Heritage Foundation proposed dismantling NOAA.
The futures of two large proposed fossil fuel projects in the North Sea have been cast into doubt after a Scottish court ruled that they should never have been approved in the first place. Equinor’s Rosebank project would harness oil from the UK’s largest untapped oilfield. Shell’s Jackdaw project would extract natural gas, which Shell claims would heat 1.4 million homes. Activists from Greenpeace and other groups challenged the projects’ approvals after an earlier ruling from the Supreme Court said that such projects must assess and disclose the downstream (Scope 3) emissions impact of burning the fossil fuels they produce, which neither Rosebank’s nor Jackdaw’s developers did. If they want to go ahead with the projects, Shell and Equinor will have to try to get them approved by the government again, this time with all the environmental impacts taken into consideration.
Researchers think they’ve solved a mystery about what’s causing bird populations in untouched areas of the rainforest to decline. Any guesses? Surprise! It’s climate change. In a new study published in the journal Science Advances, the team analyzed bird populations over nearly 30 years and found that more intense dry seasons in the Amazon “significantly” reduced the survival rates for almost all bird species they studied. In fact, they think just 1 degree Celsius of warming reduces the average survival of the tropical birds by 63%. “These findings are especially alarming because they reflect demographic patterns of tropical birds within pristine rainforest, a biome thought to be resilient to the adverse effects of climate change,” the researchers wrote.
Nearly two-thirds of Americans (64%) want to see the government increase fuel-economy standards so that vehicles continue to get more fuel-efficient.

On the budget debate, MethaneSAT’s untimely demise, and Nvidia
Current conditions: The northwestern U.S. faces “above average significant wildfire potential” for July • A month’s worth of rain fell over just 12 hours in China’s Hubei province, forcing evacuations • The top floor of the Eiffel Tower is closed today due to extreme heat.
The Senate finally passed its version of Trump’s One Big Beautiful Bill Act Tuesday morning, sending the tax package back to the House in hopes of delivering it to Trump by the July 4 holiday. The excise tax on renewables that had been stuffed into the bill over the weekend was removed after Senator Lisa Murkowski of Alaska struck a deal with the Senate leadership designed to secure her vote. In her piece examining exactly what’s in the bill, Heatmap’s Emily Pontecorvo explains that even without the excise tax, the bill would “gum up the works for clean energy projects across the spectrum due to new phase-out schedules for tax credits and fast-approaching deadlines to meet complex foreign sourcing rules.” Debate on the legislation begins on the House floor today. House Speaker Mike Johnson has said he doesn’t like the legislation, and a handful of other Republicans have already signaled they won’t vote for it.
The Environmental Protection Agency this week sent the White House a proposal that is expected to severely weaken the federal government’s ability to rein in planet-warming pollution. Details of the proposal, titled “Greenhouse Gas Endangerment Finding and Motor Vehicle Reconsideration,” aren’t clear yet, but EPA Administrator Lee Zeldin has reportedly been urging the Trump administration to repeal the 2009 “endangerment finding,” which explicitly identified greenhouse gases as a public health threat and gave the EPA the authority to regulate them. Striking down that finding would “free EPA from the legal obligation to regulate climate pollution from most sources, including power plants, cars and trucks, and virtually any other source,” wrote Alex Guillén at Politico. The title of the proposal suggests it aims to roll back EPA tailpipe emissions standards, as well.

So long, MethaneSAT, we hardly knew ye. The Environmental Defense Fund said Tuesday that it had lost contact with its $88 million methane-detecting satellite, and that the spacecraft was “likely not recoverable.” The team is still trying to figure out exactly what happened. MethaneSAT launched into orbit last March and was collecting data about methane pollution from global fossil fuel infrastructure. “Thanks to MethaneSAT, we have gained critical insight about the distribution and volume of methane being released from oil and gas production areas,” EDF said. “We have also developed an unprecedented capability to interpret the measurements from space and translate them into volumes of methane released. This capacity will be valuable to other missions.“ The good news is that MethaneSAT was far from the only methane-tracking satellite in orbit.
Nvidia is backing a D.C.-based startup called Emerald AI that “enables AI data centers to flexibly adjust their power consumption from the electricity grid on demand.” Its goal is to make the grid more reliable while still meeting the growing energy demands of AI computing. The startup emerged from stealth this week with a $24.5 million seed round led by Radical Ventures and including funding from Nvidia. Emerald AI’s platform “acts as a smart mediator between the grid and a data center,” Nvidia explains. A field test of the software during a grid stress event in Phoenix, Arizona, demonstrated a 25% reduction in the energy consumption of AI workloads over three hours. “Renewable energy, which is intermittent and variable, is easier to add to a grid if that grid has lots of shock absorbers that can shift with changes in power supply,” said Ayse Coskun, Emerald AI’s chief scientist and a professor at Boston University. “Data centers can become some of those shock absorbers.”
In case you missed it: California Governor Gavin Newsom on Monday rolled back the state’s landmark Environmental Quality Act. The law, which had been in place since 1970, required environmental reviews for construction projects and had become a target for those looking to alleviate the state’s housing crisis. The change “means most urban developers will no longer have to study, predict, and mitigate the ways that new housing might affect local traffic, air pollution, flora and fauna, noise levels, groundwater quality, and objects of historic or archeological significance,” explainedCal Matters. On the other hand, it could also mean that much-needed housing projects get approved more quickly.
Tesla is expected to report its Q2 deliveries today, and analysts are projecting a year-over-year drop somewhere from 11% to 13%.
Jesse teaches Rob the basics of energy, power, and what it all has to do with the grid.
What is the difference between energy and power? How does the power grid work? And what’s the difference between a megawatt and a megawatt-hour?
On this week’s episode, we answer those questions and many, many more. This is the start of a new series: Shift Key Summer School. It’s a series of introductory “lecture conversations” meant to cover the basics of energy and the power grid for listeners of every experience level and background. In less than an hour, we try to get you up to speed on how to think about energy, power, horsepower, volts, amps, and what uses (approximately) 1 watt-hour, 1 kilowatt-hour, 1 megawatt-hour, and 1 gigawatt-hour.
Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Here is an excerpt from our conversation:
Jesse Jenkins: Let’s start with the joule. The joule is the SI unit for both work and energy. And the basic definition of energy is the ability to do work — not work in a job, but like work in the physics sense, meaning we are moving or displacing an object around. So a joule is defined as 1 newton-meter, among other things. It has an electrical equivalent, too. A newton is a unit of force, and force is accelerating a mass, from basic physics, over some distance in this case. So 1 meter of distance.
So we can break that down further, right? And we can describe the newton as 1 kilogram accelerated at 1 meter per second, squared. And then the work part is over a distance of one meter. So that kind of gives us a sense of something you feel. A kilogram, right, that’s 2.2 pounds. I don’t know, it’s like … I’m trying to think of something in my life that weighs a kilogram. Rob, can you think of something? A couple pounds of food, I guess. A liter of water weighs a kilogram by definition, as well. So if you’ve got like a liter bottle of soda, there’s your kilogram.
Then I want to move it over a meter. So I have a distance I’m displacing it. And then the question is, how fast do I want to do that? How quickly do I want to accelerate that movement? And that’s the acceleration part. And so from there, you kind of get a physical sense of this. If something requires more energy, if I’m moving more mass around, or if I’m moving that mass over a longer distance — 1 meter versus 100 meters versus a kilometer, right? — or if I want to accelerate that mass faster over that distance, so zero to 60 in three seconds versus zero to 60 in 10 seconds in your car, that’s going to take more energy.
Robinson Meyer: I am looking up what weighs … Oh, here we go: A 13-inch MacBook Air weighs about, a little more than a kilogram.
Jenkins: So your laptop. If you want to throw your laptop over a meter, accelerating at a pace of 1 meter per second, squared …
Meyer: That’s about a joule.
Jenkins: … that’s about a joule.

If the Senate reconciliation bill gets enacted as written, you’ve got about 92 days left to seal the deal.
If you were thinking about buying or leasing an electric vehicle at some point, you should probably get on it like, right now. Because while it is not guaranteed that the House will approve the budget reconciliation bill that cleared the Senate Tuesday, it is highly likely. Assuming the bill as it’s currently written becomes law, EV tax credits will be gone as of October 1.
The Senate bill guts the subsidies for consumer purchases of electric vehicles, a longstanding goal of the Trump administration. Specifically, it would scrap the 30D tax credit by September 30 of this year, a harsher cut-off than the version of the bill that passed the House, which would have axed the credit by the end of 2025 except for automakers that had sold fewer than 200,000 electric vehicles. The credit as it exists now is worth up to $7,500 for cars with an MSRP below $55,000 (and trucks and sports utility vehicles under $80,000), and, under the Inflation Reduction Act, would have lasted through the end of 2032. The Senate bill also axes the $4,000 used EV tax credit at the end of September.
“Long story short, the credits under the current legislation are only going to be on the books through the end of September,” Corey Cantor, the research director of the Zero Emission Transportation Association, told me. “Now is definitely a good time, if you’re interested in an EV, to look at the market.”
The Senate applied the same strict timeline to credits for clean commercial vehicles, both new and used. For home EV chargers, the tax credit will now expire at the end of June next year.
While EVs were on the road well before the 2022 passage of the Inflation Reduction Act, what the new tax credit did was help build out a truly domestic electric vehicle market, Cantor said. “You have a bunch of refreshed EV models from major automakers,” Cantor told me, including “more affordable models in different segments, and many of them qualify for the credit.”
These include cars produceddomestically by Kia,Hyundai, and Chevrolet. But of course, the biggest winner from the credit is Tesla, whose Model Y was the best-selling car in the world in 2023.
Tesla shares were down over 5.5% in Tuesday afternoon trading, though not just because of Congress. JPMorgan also released an analyst report Monday arguing that the decline in sales seen in the first quarter would accelerate in the second quarter. President Trump, with whom Tesla CEO Elon Musk had an extremely public falling out last month, suggested on social media Monday night that the government efficiency department Musk himself formerly led should “take a good, hard, look” at the subsidies Musk receives across his many businesses. Trump also said that he would “take a look” at Musk’s United States citizenship in response to reporters’ questions about it.
Cantor told me that he expects a surge of consumer attention to the EV market if the bill passes in its current form. “You’ve seen more customers pull their purchase ahead” when subsidies cut-offs are imminent, he said.
But overall, the end of the subsidy is likely to reduce EV sales from their previously expected levels.
Harvard researchers have estimated that the termination of the EV tax credit “would cut the EV share of new vehicle sales in 2030 by 6.0 percentage points,” from 48% of new sales by 2030 to 42%. Combined with other Trump initiatives such as terminating the National Electric Vehicle Infrastructure program for publicly funded chargers (currently being litigated) and eliminating California’s waiver under the Clean Air Act that allowed it to set tighter vehicle emissions standards, the share of new car sales that are electric could fall to 32% in 2030.
But not all government support for electric vehicles will end by October 1, even if the bill gets the president’s signature in its current form.
“It’s important for consumers to know there are many states that offer subsidies, such as New York, and Colorado,” Cantor told me. That also goes for California, New Jersey, Nevada, and New Mexico. You can find the full list here.
