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.

What J.P. Morgan’s Chief Climate Advisor Is Telling Energy Startups

Rob talks with Sarah Kapnick about our new era of energy insecurity.

We live in a new energy era — one in which the inputs and technologies key to clean electricity production are at the heart of international politics. What will that mean for decarbonization? And how should climate tech companies prepare?

On this week’s episode of Shift Key, Rob chats about those questions and more with Dr. Sarah Kapnick. She is the Global Head of Climate Advisory at J.P. Morgan, where she advises the bank's clients on climate, energy, biodiversity and sustainability topics. She was the former chief scientist at the National Oceanic and Atmospheric Administration from 2022 to 2024, and was previously a research scientist at NOAA’s Geophysical Fluid Dynamics Laboratory in Princeton, New Jersey.

Why Mining Is the Dirty Underbelly of the Clean Energy Transition

Thea Riofrancos, a professor of political science at Providence College, discusses her new book, Extraction, and the global consequences of our growing need for lithium.

We cannot hope to halt or even slow dangerous climate change without remaking our energy systems, and we cannot remake our energy systems without environmentally damaging projects like lithium mines.

This is the perplexing paradox at the heart of Extraction: The Frontiers of Green Capitalism, a new book by political scientist and climate activist Thea Riofrancos, coming out September 23, from Norton.

Elon Musk Defeats Reality, Again

The CEO’s $1 billion share buy changes nothing — except in the eyes of his shareholders.

Elon Musk’s signature talent, the thing that made him the world’s richest man, has long been his ability to make Tesla’s stock price soar. It’s a superpower that manifests through a combination of financial lever-pulling and promises of world-changing innovations to come. For this reason, it leads to glaring disconnects such as Tesla having become the world’s most valuable automaker despite selling only a 10th as many vehicles as a true manufacturing superpower like Toyota.

By that yardstick, this week’s news might be his biggest achievement yet.
