Rob interviews Ali Zaidi at Yale.

What’s next for the Biden administration — and for climate policy in the United States? Should Democrats negotiate with Republicans over permitting reform, even if it means making concessions to fossil fuel interests? And how should the country’s trade policy handle the problem of carbon pollution?
On this week’s episode of Shift Key, Rob speaks with Ali Zaidi, the national climate advisor to President Joe Biden. Zaidi leads the White House Climate Policy Office, which coordinates domestic climate policy across federal agencies. Before joining the White House in 2021, Zaidi was the state of New York’s deputy secretary for energy and environment. This interview was recorded live on October 10 in New Haven, Connecticut, at the Yale Clean Energy Conference.
Shift Key is hosted by Robinson Meyer, the founding executive editor of Heatmap, and Jesse Jenkins, a professor of energy systems engineering at Princeton University. Jesse is out this week.

Here is an excerpt from our conversation:
Ali Zaidi: The conversation in Congress right now makes it seem like transmission is a Democratic policy priority when it boosts reliability and lowers rates. I thought Republicans and Democrats both agreed we need to boost reliability and lower rates. So I don’t know why that needs to be offset by any measure.
That’s thing number one. Thing number two is …
Robinson Meyer: This is the challenge of talking about things, is that if Democrats say, oh, we really value this, then suddenly it’s a Democratic priority.
Zaidi: Yeah. And then the second is, how do we accelerate the siting and permitting of things and then there is a how do we shift more power to the oil and gas industry. The conversation around leasing, happening against a backdrop where the industry itself is moving away from long-cycle investment to short-cycle investment, it’s tough. So I would hope that more of the permitting conversation were a permitting conversation.
Meyer: Well, one way this sometimes gets reflected is that you’ll hear environmentalists say, any policy that makes the oil and gas industry happy or bigger, we should not take. And that makes making a compromise …
Zaidi: And I reject that. Yeah, look, if ExxonMobil wants to pay for a pipeline that will help us deliver what was once solar and wind, as a fuel, to help us decarbonize a steel plant, they can be for it and I can be for it. If there is a — Blackstone, for example, has a Project Tallgrass that has converted a pipeline that used to pull hydrocarbons out of the ground. It’s now flipped the pipeline around, and is putting CO2 into the ground.
They can be for that. I can be for that — not speaking to the specific project, but conceptually. So I don’t think … It’s not the actor. It’s the question of whether this is directionally consistent with trying to chase down a 1.5 degree future or not.
We are behind as a world, and we need to run faster in that direction. If it’s not directionally consistent, that’s a problem.

By neutering the Corporate Average Fuel Economy standards, the Trump administration cements the country’s dependence on oil and liquid fuels.
This is Heatmap Daily, a weekday news digest written by our executive editor.
President Trump’s big fuel efficiency rollback is here. This afternoon, the Department of Transportation significantly weakened the Corporate Average Fuel Economy standards, the federal government’s rules that encourage new cars and trucks to get gradually more fuel-efficient over time. Instead of mandating that new cars and trucks hit a target of more than 50 miles per gallon, as the old Biden-era rules had required, new vehicles sold in the U.S. will now need to average only 34.9 miles per gallon.
That target is below the level that most automakers have already achieved in their vehicle fleet. (For reasons too obscure to recount here, the regulatory standard of 34 miles per gallon aligns to real-world gas mileage in the mid-to-high 20s — something my 15-year-old hatchback manages to achieve without much straining.) The new rules also retroactively rewrite the standard back to 2022, meaning that automakers whose fleets once broke the law may now be in the clear.
These changes, in other words, render the fuel economy law, first enacted in 1975, is now moot. But Republicans in Congress had arguably already achieved this last year, when they zeroed out all of the law’s fines for automakers as part of the president’s tax and spending bill. These two changes, taken together, mean that the Trump administration has successfully neutered the U.S. fuel efficiency rules.
We are digging into the rule-making here at Heatmap, and I hope to have more on the documents in the days to come. But one of the lasting ironies of President Trump’s approach to fuel efficiency will be that his own presidency demonstrates its strategic inadequacy.
The Corporate Average Fuel Economy law, after all, did not originate as an environmental policy — climate change had scarcely emerged as a pressing issue in the mid-1970s — but as a national security and economic sovereignty measure. In the aftermath of the oil embargo, American politicians realized that the U.S. economy was far too dependent on oil for its long-term good. This set off a scramble to find new energy sources, prompting a dash back to coal in the electricity sector and a surge in federal R&D spending on alternative energy. (This funding boost eventually created the modern solar, wind, battery, and fracking industries.)
It also led to a successful push to regulate gas mileage. Crucially, this effort did not limit emissions from any one type of vehicle, as the Environmental Protection Administration’s toxic air pollution rules aim to do. Rather, it targeted the average fuel efficiency of cars and light-duty trucks sold in the United States in each model-year. The point was not to regulate any one type of vehicle out of existence, but to increase the country’s overall fuel efficiency over time.
That decades-long effort was never perfect. It created in American statute, for instance, a lasting distinction between cars and trucks, which has bedeviled regulators as SUVs have taken up a larger portion of the new vehicle fleet. But it has also inarguably succeeded: The United States ekes far more value out of every barrel of oil today than it did half a century ago.
Yet the time is ripe to keep making progress. President Trump’s administration has illustrated the persistence of our oil dependence — and the political and strategic problems that it can still engender. Even though the United States has since become the world’s largest producer of oil, the linked and globalized nature of fuel markets means that a supply shock anywhere leads to price hikes everywhere. When an oil crisis arrives — even a largely self-inflicted one, as in the case of the Iran war — then the price of moving things and people rises, the economy suffers, and the president’s popularity falls. Countries can protect themselves from these shocks on a short-term basis by stockpiling oil (as the United States, in fact, does), but they can avoid them only by switching to a far more efficient and electrified transportation system.
President Trump, in other words, may regret the current oil and refining crisis. But by gutting the fuel economy standards — and waging war on electric vehicle incentives more broadly — he is increasing the likelihood that America will face many more crises like it in future years. Consider it his particular gift to his successors.
The cofounders of The Impact Project have a three-step test for voters.
In November 2025, Texas Governor Greg Abbott announced a $40 billion Google investment in his state and declared, “Texas is the epicenter of AI development, where companies can pair innovation with expanding energy.” At a campaign stop in East Texas seven months later, he had a different message: “We must prohibit them from building AI data centers in rural Texas neighborhoods.” Last week, Abbott instructed Texas’ environmental agency to stop issuing permits to data center projects until the state’s grid operator completes an audit of all data centers in the interconnection process.
Abbott is not alone. In the past week, three other candidates for governor moved toward limits. On September 23, Maryland Governor Wes Moore, a Democrat, signed an executive order tying state incentives for large projects to a new review process, pledged that “the state will not go around a local community’s ‘no,’” and announced that he would ask lawmakers to repeal the state’s data center tax exemption, passed in 2020. The same day, Kansas Democratic nominee Cindy Holscher, who voted for data center tax incentives as a state senator and now backs a moratorium, said she “certainly would vote differently based on the information we have now.” Teri Ann Hourihan, Arizona’s No Labels candidate, also promised a “Day 1” moratorium on new data centers.
These shifts represent a pattern we’re seeing across party lines during an election season dominated by conversations about data centers and artificial intelligence. At The Impact Project, we track where the candidates for governor stand on data centers: 143 candidates in 36 states and three territories. By our count, 69 of the 78 major party candidates have voiced positions on data centers. Thirty-eight candidates have staked out restrictive positions on data centers, while 31 are supportive, ranging from unequivocal support to reluctant support with significant safeguards and concessions. Importantly, we counted a candidate as supportive if they champion data center development, even if they want a pause or a moratorium to take a closer look first.
Across party lines, candidates appear to be trying to balance environmental and social concerns with economic and technological priorities. At least 30 support a pause, halt, moratorium, or ban, including 20 Democrats and 10 Republicans. In five states — Maine, New Hampshire, Ohio, Oregon, and Texas — the Democratic and Republican candidates both clearly back a pause. Among sitting governors up for reelection, a quarter back a pause; among major party candidates newly seeking the job, 43% do. The 65 third-party and independent candidates lean further toward restriction: We documented positions for 32 of them, including 19 who back a pause, moratorium, or ban. Today, we are making our research publicly available.
Candidates appear to be following voters, whose opinions have shifted rapidly. In September 2025, Americans were evenly divided over whether they would support a data center being built near their homes. By August, 75% opposed one. In Virginia, the share of voters comfortable with a new data center in their community fell from 69% in 2023 to 35% in 2026 in 2026. In May of this year, seven in 10 Americans told Gallup they oppose AI data centers in their area, with the strongest opposition in the Midwest and the South. Voters’ complaints are concrete, concerning water use, air pollution, persistent noise, rising utility bills, and projects negotiated under nondisclosure agreements without neighbor consent.
Candidates should be responsive to their constituents’ priorities, but the electorate is naturally skeptical when candidates shift their positions so dramatically during an election year. These pivots invite questions about whether some candidates’ new skepticism of the data center boom will last beyond November.
In Nevada, Democratic nominee Aaron Ford co-sponsored the 2015 law that created the state’s data center tax abatements. He now promises to pause them. His Republican opponent, incumbent Governor Joe Lombardo, once called data centers the state’s new “gold rush.” On September 18, less than two months before the election, he signed an executive order curbing the tax breaks. Arizona Governor Katie Hobbs, a Democrat, told lawmakers in January that she voted for the state’s data center tax exemption as a legislator, and that she now wants to eliminate it. Wisconsin’s Republican nominee, Tom Tiffany, called data centers “exciting new technology” in January. His campaign now says, “[w]e are America’s Dairyland, not America’s Dataland.”
Pennsylvania’s Republican nominee, Stacy Garrity, was even more blunt: Last summer she praised data center deregulation and expansion. This June, Garrity announced that “we pause for as long as we need the pause.” Garrity’s opponent, incumbent Democrat governor Josh Shapiro, has similarly flipped: Last year, Shapiro celebrated fast-tracking permitting for data center and AI development. This year, Shapiro signed an executive order proposing limits on data centers and has spoken about developers “running roughshod” over communities. In Ohio, billionaire Republican gubernatorial candidate Vivek Ramaswamy called his state’s data center boom “great” in 2025. Now he promises an executive order pausing construction.
Candidates, of course, are allowed to change their minds, and these changes may be sincere. Our understanding of the burdens of data centers is growing along with the industry. The vast AI hyperscalers being built today are not the server farms of 2015, which is how Nevada’s Ford explained his shifting position.
Are we witnessing political convenience or a real change of heart? No one can see inside a candidate’s head. Voters can, however, check three things.
First, does a candidate’s promise come with a plan? Many of the loudest pledges are for a “Day 1” executive order. Executive orders are the easiest policy to make and the easiest to undo, and a pause is hollow without regulatory action to follow it up. We can ask what bill language the candidate would support, what it would require, and what happens the day a proposed pause ends. We can also question whether the candidate can deliver. Utility rates are set by public utility commissions, not governors, and tax incentives are written into law. A governor can stop new deals, but signed deals keep running. Lombardo’s order, for instance, applies only to companies seeking new tax breaks.
Second, does the plan require disclosure? We cannot regulate what we cannot measure. Many candidates describe their pause as time to study the problem. Maryland’s Republican nominee, Dan Cox, wants a moratorium “so that we can study this.” A study needs data, and data centers developers and operators are famously opaque. As data is so infrequently available directly from data centers, journalists, activists, and researchers have resorted to techniques as varied as satellite imagery, public records requests, thermal drone footage, tax document sleuthing, and human tips to collect data and break news about data centers. Yet fewer than a quarter of candidates who call for a pause call for mandatory disclosure. A pause without reporting requirements ends where it started: without the facts needed to regulate.
Third, what did the candidate do before this was popular? Votes, signed deals, and ribbon cuttings are public record. A candidate who switched should be able to say what changed and what they got wrong. One who cannot is asking voters to trust the new position on faith.
After November, voters can keep score. Watch the first legislative session and the first budget. Do data center incentives come back under a new name? Does a “Day 1” pause end with rules, or does it simply end? Communities have already shown what accountability looks like locally, where residents have recalled officials and replaced council members who approved unpopular projects. Governors deserve the same attention.
What voters want is reasonable. When a Michigan poll asked about a data center within 25 miles of home, 55% said they were not open to it, 11% were not sure, and only 33% said they were open to it. After hearing a set of protections, including no rate hikes, no tax incentives or secret deals, and closed-loop cooling, 49% said they would be open to one. What most voters oppose is data centers without rules.
Americans are demanding change, and data centers are top of mind. Candidates who mean what they say will make good on campaign promises by writing rules and passing them. The rest will let their hollow promises lapse and hope no one is counting. We all should be.
The renewables developer is expanding its business to serve “our nation’s growing energy needs.”
Two years ago, Arevia Power marketed itself as a renewable energy development powerhouse founded by solar industry veterans.
Today, the company is now also building data centers and gas turbines, Arevia chief development officer Ricardo Graf confirmed in a statement to me.
“Arevia is an energy company that delivers reliable and affordable electricity to the communities and utilities we serve,” Graf told me via email, acknowledging that “in some cases, that energy may be solar; in others, it may be gas.” He added that “yes, we also develop data center projects, but ones with accompanying power solutions to ensure ratepayers are not impacted by the data center’s energy needs.”
I’ve been keeping a close eye out to see whether any renewable energy developers, faced with the Trump administration’s squeeze on federal permits, will bet on diversifying their businesses. Maybe if they couldn’t build a solar farm on federal lands or access ample federal tax credits for constructing new projects, they’d invest in other sorts of large infrastructure projects instead.
We’ve definitely seen large U.S. energy developers such as NextEra and Invenergy take Trumpian tacks towards supplying data centers with new gas power under. Over the summer I broke the news that Clearway Energy asked the Bureau of Land Management to change a five year-old application for solar farm permits with “a proposed data center and natural gas facility.” After those plans were made public, Clearway told me in a statement to me that it was nixing the idea because it did not comport with their business strategy. “As a clean energy developer and operator, our focus in Nevada remains solar and battery storage.”
In mid-September, D.C. news outlet The Washington Sun first reported that Rhea Data, a subsidiary of Arevia Power, was behind the proposal for a giant data center and energy complex in Idaho including thousands of acres of federal land. On Thursday, the Bureau of Land Management sent me a statement confirming key details such as the inclusion of a 450-megawatt on-site gas facility. The next day, a Nebraska public radio station reported that Arevia and Graf were connected to prospective early-stage data center project site evaluation outside the city of Lincoln.
When I asked whether the company was reorienting itself toward data centers and the gas energy business, Graf acknowledged how things looked. “While this may be perceived as ‘pivoting,’ it is just a product of the evolution of our nation’s growing energy needs, which solar alone cannot satisfy,” he said over email on Friday. “Our company takes an all-above approach to helping our nation meet its increasing power demands.”
