Did the Supreme Court just make it easier to build things in this country — or did it give a once-in-a-lifetime gift to the fossil fuel industry? Last week, the Supreme Court ruled 8-0 against environmentalists who sought to use a key permitting law, the National Environmental Policy Act, to slow down a railroad in a remote but oil-rich part of Utah. Even the court’s liberals ruled against the green groups.

But the court’s conservative majority issued a much stronger and more expansive ruling, urging lower courts to stop interpreting the law as they have for years. That decision, written by Justice Brett Kavanaugh, may signal a new era for what has been called the “Magna Carta” of environmental law.

On this week’s episode of Shift Key, Rob and Jesse talk with Nicholas Bagley, a University of Michigan law professor and frequent writer on permitting issues. He is also Michigan Governor Gretchen Whitmer’s former chief legal counsel. Rob, Jesse, and Nick discuss what NEPA is, how it has helped (and perhaps hindered) the environment, and why it’s likely to change again in the near future. Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Shift Key is off this week for Memorial Day, so we’re re-running one of our favorite episodes from the past. With Republicans in the White House and Congress now halfway to effectively repealing the Inflation Reduction Act, the United States’ signature climate law, we thought now might be a good moment to remind ourselves why emissions reductions matter in the first place.

To that end, we’re resurfacing our chat from November with Kate Marvel, an associate research scientist at Columbia University and the NASA Goddard Institute for Space Studies. At the time, Trump had just been reelected to the presidency, casting a pall over the annual United Nations climate conference, which was then occurring in Azerbaijan. Soon after, he fulfilled his promise to pull the U.S. out of the Paris Agreement, with its goal of restraining global warming to 1.5 degrees Celsius over pre-industrial levels.

In this episode, we talk with Kate about why every 10th of a degree matters in the fight against climate change, the difference between tipping points and destabilizing feedback loops, and how to think about climate change in a disappointing time. 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.

Republicans are preparing to tear up America’s clean energy tax credits as part of their budget reconciliation megabill. Hollowing out those policies will have sweeping implications for the country’s energy system — it could set back solar, nuclear, and geothermal development; bring less electricity supply onto the grid; and devastate the country’s fledgling electric vehicle supply chain.

A new report — written by our own Jesse Jenkins — is all about the real-life consequences of killing the tax credits. On this week’s episode of Shift Key, Jesse shares the forthcoming analysis of the bill from Princeton University’s REPEAT Project. Rob and Jesse discuss what best-in-class modeling tells us the bill will mean for carbon emissions, the energy economy, the power grid, and consumer energy costs. Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

The fight over the Inflation Reduction Act has arrived. After months of discussion, the Republican majority in the House is now beginning to write, review, and argue about its plans to transform the climate law’s energy tax provisions.

We wanted to record a show about how to follow that battle. But then — halfway through recording that episode — the Republican-controlled House Ways and Means Committee dropped the first draft of their proposal to gut the IRA, and we had to review it on-air.

We were joined by Luke Bassett, a former senior advisor for domestic climate policy at the U.S. Treasury Department, and a former senior staff member at the Senate Committee on Energy and Natural Resources. We chatted about the major steps in the reconciliation process, what to watch next, and what to look for in the new GOP draft. Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Last week, more than 50 million people across mainland Spain and Portugal suffered a blackout that lasted more than 10 hours and shuttered stores, halted trains, and dealt more than $1 billion in economic damage. At least eight deaths have been attributed to the power outage.

Almost immediately, some commentators blamed the blackout on the large share of renewables on the Iberian peninsula’s power grid. Are they right? How does the number of big, heavy, spinning objects on the grid affect grid operators’ ability to keep the lights on?

On this week’s episode of Shift Key, Jesse and Rob dive into what may have caused the Iberian blackout — as well as how grid operators manage supply and demand, voltage and frequency, and renewables and thermal resources, and operate the continent-spanning machine that is the power 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.

Texas is one of the country’s biggest producers of zero-emissions energy. Last year, the Lone Star State surpassed California to become the country’s No. 1 market for utility-scale solar. More solar and batteries were added to the Texas grid in 2024 than any other energy source, and the state has long dominated in onshore wind.

But that buildout is now threatened. A new tranche of bills in the Texas House and Senate could impose punitive engineering requirements on wind, solar, and storage plants — even those already in operation — and they could send the state’s power bills soaring.

Doug Lewin is the founder and CEO of Stoic Energy Partners in Austin, Texas. He writes the Texas Energy and Power Newsletter, and he is the host of the Energy Capital podcast. On this week’s episode of Shift Key, Jesse and Rob talk with Doug about how Texas became a clean energy powerhouse, how it has dealt with eye-watering demand power growth, and why a handful of bills in the Texas statehouse could break its electricity market. 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.

In just the past few years, Chinese EV-maker BYD has become the most important car company most Americans have still never heard of. It is China’s biggest private employer, the world’s third most valuable automaker (after Tesla and Toyota), and it’s capable of producing more than 5 million cars a year. It’s also just one of dozens of innovative new Chinese auto companies that are set to transform the global mobility market — regardless of what happens with Trump’s tariffs.

On this week’s episode of Shift Key, Jesse and Rob talk with Michael Dunne, the founder of Dunne Insights and a longtime observer of the Chinese automotive sector. Dunne was president of GM Indonesia from 2013 and 2015, and was once managing director of JD Power and Associates’ China division. We talk about the deep history of BYD, the five non-BYD Chinese car companies you should know, and how Western automakers could (with difficulty and a lot of policy help) eventually catch up.

Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Donald Trump has implemented what is easily the most chaotic set of American economic policies in recent memory. First, the U.S. declared a trade war on the entire world, imposing breathtaking tariffs on many of the country’s biggest trading partners. He’s paused that effort — but scaled up punitive tariffs on China, launching what would be the 21st century’s biggest global economic realignment without any apparent plan. Now Trump says that more levies are coming on semiconductors and pharmaceuticals, no matter where we get them.

All of this is a disaster for the U.S. economy — but it’s also ruinous for any potential American role in decarbonization or the fight against climate change. Even more than Trump’s deregulatory actions, his trade war could spell the end of a long-held U.S. decarbonization dream.

On this week’s episode of Shift Key, Rob and Jesse chat about what Trump’s chaotic economic policy could mean for the global fight against climate change. What happens to global decarbonization if the U.S. no longer participates? If the U.S. kills its research sector, what happens next? And could China seize this moment to expand its clean tech sector? Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.
