The Biggest Lessons of a Not-So-Great Year for Climate Policy

Jesse and Rob take stock of 2025.

2025 has been incredibly eventful for decarbonization — and not necessarily in a good way. The return of Donald Trump, the One Big Beautiful Bill Act, and the rise of data centers and artificial intelligence led to more changes for climate policy and the clean energy sector than we’ve seen in years. Some of those we saw coming. Others we really did not.

On this week’s episode of Shift Key, Rob and Jesse look back at the year’s biggest energy and decarbonization stories and examine what they got right — and what they got wrong. What’s been most surprising about the Trump administration? Why didn’t the Inflation Reduction Act’s policies help prevent the law’s partial repeal? And why have AI and the data center boom become a much bigger driver of power growth than we once thought?

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.

Here is an excerpt from our conversation:

Jesse Jenkins: I think what I’m saying on the organizing side is that all of the organizing and comms effort was going in, as you pointed out, to a base-building and turnout strategy, not a constituency-expanding, coalition-building strategy, right? The effort was to go deep, not wide.

I think that was the fundamental mistake because there wasn’t a lot of depth there. There wasn’t this big, untapped pool of youth voters waiting to be turned out. And it meant we put basically no effort into expanding the broad set of constituencies that, for various ideological backgrounds and various motivations, could have all agreed that hey, bringing manufacturing jobs back to America finally after 20 years of politicians talking about it is maybe a good thing we want to sustain. Hey, lowering energy prices by building new energy supplies at a time when demand is growing, that’s a good idea, maybe we should sustain that, right? Creating tax bases in rural areas through investment in solar farms and wind farms — maybe that’s a good thing we should sustain.

Politics isn’t about getting everybody to agree on motivation, right? It’s about getting people to agree on what we’re going to do as a body politic. And unfortunately, that’s what I guess I’m getting at by this hyperpartisan, ideologically-driven world is, now it is all about getting everybody to agree on motivations, and —

Robinson Meyer: That’s what I was going to say. I actually think it’s —

Jenkins: And that’s just a terrible way to make policy. And I guess it makes this all that much harder.

Meyer: I think for me, I fear we’ve run the climate base experiment so well now that people have gotten this message, and people are starting to understand these policies in terms of energy affordability or clean energy policy. And that means lots of good things for clean energy. I think people should keep making the argument because it seems to me to be true that, for instance, the One Big Beautiful Bill Act’s termination of the wind and solar tax credits is going to mean bad things for American electricity customers. It’s going to raise rates.

But I do think that we should take the full lesson of the IRA experience and say, look, if people care about affordability and you tell them you’re working for affordability, you actually do need to put affordability at the center of your policies. And you need to be willing to understand that there is a tradeoff between affordability and emissions, but unfortunately, the electorate might care about affordability.

The Last Time America Tried to Legislate Its Way to Energy Affordability

Lawmakers today should study the Energy Security Act of 1980.

The past few years have seen wild, rapid swings in energy policy in the United States, from President Biden’s enthusiastic embrace of clean energy to President Trump’s equally enthusiastic re-embrace of fossil fuels.

Where energy industrial policy goes next is less certain than any other moment in recent memory. Regardless of the direction, however, we will need creative and effective policy tools to secure our energy future — especially for those of us who wish to see a cleaner, greener energy system. To meet the moment, we can draw inspiration from a largely forgotten piece of energy industrial policy history: the Energy Security Act of 1980.

Current conditions: Nearly two dozen states from the Rockies through the Midwest and Appalachians are forecast to experience temperatures up to 30 degrees above historical averages on Christmas Day • Parts of northern New York and New England could get up to a foot of snow in the coming days • Bethlehem, the West Bank city south of Jerusalem in which Christians believe Jesus was born, is preparing for a sunny, cloudless Christmas Day, with temperatures around 60 degrees Fahrenheit.

This is our last Heatmap AM of 2025, but we’ll see you all again in 2026!

THE TOP FIVE

1. Trump halts construction on all offshore wind projects

Just two weeks after a federal court overturned President Donald Trump’s Day One executive order banning new offshore wind permits, the administration announced a halt to all construction on seaward turbines. Secretary of the Interior Doug Burgum announced the move Monday morning on X: “Due to national security concerns identified by @DeptofWar, @Interior is PAUSING leases for 5 expensive, unreliable, heavily subsidized offshore wind farms!” As Heatmap’s Jael Holzman explained in her writeup, there are only five offshore wind projects currently under construction in U.S. waters: Vineyard Wind, Revolution Wind, Coastal Virginia Offshore Wind, Sunrise Wind, and Empire Wind. “The Department of War has come back conclusively that the issues related to these large offshore wind programs create radar interference, create genuine risk for the U.S., particularly related to where they are in proximity to our East Coast population centers,” Burgum told Fox Business host Maria Bartiromo.

Google Is Cornering the Market on Energy Wonks

Google is on an AI hiring spree — and not just for people who can design chips and build large language models. The tech giant wants people who can design energy systems, too.

Google has invested heavily of late in personnel for its electricity and infrastructure-related teams. Among its key hires is Tyler Norris, a former Duke University researcher and one of the most prominent proponents of electricity demand flexibility for data centers, who started in November as “head of market innovation” on the advanced energy team. The company also hired Doug Lewin, an energy consultant and one of the most respected voices in Texas energy policy, to lead “energy strategy and market design work in Texas,” according to a note he wrote on LinkedIn. Nathan Iyer, who worked on energy policy issues at RMI, has been a contractor for Google Clean Energy for about a year. (The company also announced Monday that it’s shelling out $4.5 billion to acquire clean energy developer Intersect.)
