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.

China Is Developing a Taste for Fake Meat

Alternative proteins have floundered in the U.S., but investors are leaning in elsewhere.

Vegans and vegetarians rejoiced throughout the 2010s as food scientists got better and better at engineering plant and fungi-based proteins to mimic the texture, taste, and look of meat. Tests showed that even some meat enthusiasts couldn’t tell the difference. By the end of the decade, “fake meat” was booming. Burger King added it to the menu. Investment in the sector topped out at $5.6 billion in 2021.

Those heady days are now over — at least in the U.S. Secretary of Health and Human Services Robert F. Kennedy, Jr. champions a “carnivore diet,” price-conscious Americans are prioritizing affordable calories, and many consumers insist the real thing still simply tastes better. Investment in alternative proteins has fallen each year since 2021, with the industry raising a comparably meager $881 million in 2025.

Scoop: FEMA Cancels All Emergency Manager Trainings

Except for those related to the FIFA World Cup.

The Federal Emergency Management Agency has suspended all of its training and education programs for emergency managers across the country — except for those “directly supporting the 2026 FIFA World Cup.”

FEMA’s National Training and Education Division offers nearly 300 courses for local first responders and emergency managers, while FEMA’s National Disaster and Emergency Management University (formerly called the Emergency Management Institute) acts as the central training organization for emergency management in the United States. Since funding for the Department of Homeland Security lapsed on February 14, FEMA has instructed NTED partners to “cease course delivery operations,” according to communication reviewed by Heatmap. The NDEMU website and independent study materials have also been taken down.

Trump’s Renewables Permitting Thaw Is Also a Legal Strategy

The administration has begun shuffling projects forward as court challenges against the freeze heat up.

The Trump administration really wants you to think it’s thawing the freeze on renewable energy projects. Whether this is a genuine face turn or a play to curry favor with the courts and Congress, however, is less clear.

In the face of pressures such as surging energy demand from artificial intelligence and lobbying from prominent figures on the right, including the wife of Trump’s deputy chief of staff, the Bureau of Land Management has unlocked environmental permitting processes in recent weeks for a substantial number of renewable energy projects. Public documents, media reports, and official agency correspondence with stakeholders on the ground all show projects that had ground to a halt now lurching forward.
