Shift Key Is Opening the Mail Bag

Answering your questions on AI and energy, the economics of solar, the Green New Deal’s legacy, and more.

Happy new year! On this week’s episode of Shift Key, Rob and Jesse answer some of the questions they’ve received from readers throughout the year. Hot topics include: What happened to the Green New Deal, and is the Inflation Reduction Act part of its legacy? Should U.S. policy prioritize solar manufacturing or solar deployment? And how can normal people keep AI-driven data centers from blowing up the grid?

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: If you build a tariff wall around America and you say, You must buy American-made panels or pay a huge tariff, we could build a domestic solar manufacturing sector, but it would by no means be required to be globally competitive. And if you were to remove those protections, it would probably immediately collapse. […] If you want to, you have a competitive agenda, you need to be developing a particular type of industry that can be competitive. And I think that Michael’s question hints that maybe that’s not that important in the case of solar because it’s just not a very high-margin business. It’s kind of a bad business to be in. There’s consistent overcapacity and margins are thin, if not non-existent.

Robinson Meyer: Jenny Chase At BloombergNEF, who is the master of solar manufacturing, consistently describes it as one of the worst businesses in the world because these Chinese manufacturers — and now, more broadly, these Chinese and Southeast Asian manufacturers — are just constantly competing each other out of business.

I will say, I want to attach an asterisk to globally competitive, right? There’s like a B part to that, which is, do you think dominating in this industry is going to create know-how that allows you to dominate future technologies we don’t understand yet?

Jenkins: Yeah, are there general-purpose manufacturing techniques or core technology components here that you think are going to be useful in a variety of other sectors? I think that’s true.

I look at batteries, for example, as a critical general-purpose technology for the 21st century, right? Like, good batteries are going to be in everything, and so the ability to produce those and to continue to innovate and be at the frontier there, it’s important to national defense. It’s important to the transportation sector. It’s important to consumer products. You know, it’s just a critical platform technology, and a lot of the innovations in material science and electrochemistry and other things that you need to develop for batteries have other broader applications in decarbonizing industry and producing other products.

So I think that’s a good example of a case where, even if you’re a little behind the technology or frontier, there’s a lot of value to trying to catch up there for, for broader reasons.

Everything Happened at Heatmap House

Tales from a day of “thoughtful dialogues on energy, climate change, and human lives” on Day 3 of New York Climate Week.

“I’m here because I love thoughtful dialogues on energy, climate change, and human lives,” Energy Secretary Chris Wright told my colleague Robinson Meyer this afternoon. “That’s been a passion my whole life, and nothing will change that.”

It’s our passion too — and was a defining theme of Heatmap House on Wednesday at New York Climate Week, with 27 sessions across topics including clean energy development, U.S. climate policy, the future of mobility, climate tech, and reindustrialization. From Wright backpedaling on President Trump’s embrace of a diesel export ban to former Vice President Al Gore asserting that 2026 might mark “the positive tipping point on climate,” it was a full day of news, contrarian opinions, juicy predictions, and lots and lots of coffee (consumed by yours truly).

The Fusion Industry Needs $10 Billion to Beat China

Without billions in new federal investment the United States may lose its pole position in the global race to be the first nuclear fusion superpower, Commonwealth Fusion Systems CEO Bob Mumgaard told attendees at Heatmap House in New York City.

When asked onstage whether Commonwealth Fusion could still develop its fusion aspirations at scale without U.S. government financing, Mumgaard said: “I think so – it’s a question of the timing and the place.” Then he suggested that the company — and the industry — might go elsewhere if the country doesn’t put more capital into the growing sector. “There are offers on the table to build nuclear fission power plants not in the United States, so we can do that.”

The Climate Case for EVs Goes Deeper Than You Think

On the surface, the climate case for electric vehicles is simple: Battery-powered cars can eliminate our need to burn dirty gasoline and diesel, and as more renewables come onto the grid, they’ll only run more and more cleanly. But the benefits that can be gained from electrifying the vehicle fleet run far deeper, a case that a variety of speakers made at Heatmap House on Wednesday as part of New York Climate Week.

Andrew Peterman, director of advanced energy solutions at the EV maker Rivian, explained how electric vehicles are becoming a multi-tiered grid solution. Rivian itself is cooperating with drivers and utilities to create automatic smart charging so that EVs can charge when energy is abundant and inexpensive, saving the user money — in some cases as much as $1,000 per year — and easing strain on the grid. Doing so helps to keep electricity prices down, which is good for the country and for the bottom line of an electric vehicle maker.
