Shift Key with Robinson Meyer and Jesse Jenkins

Trump’s Move to Kill the Clean Air Act’s Climate Authority, Forever

The Trump administration has formally declared that carbon dioxide and other greenhouse gases are not dangerous pollutants. If the president gets his way, then the Environmental Protection Agency may soon surrender any ability to regulate heat-trapping pollution from cars and trucks, power plants, and factories — in ways that a future Democratic president potentially could not reverse.On this week’s episode of Shift Key, we discuss whether Trump’s EPA gambit will work, the arguments that the administration is using, and what it could mean for the future of U.S. climate and energy policy. We’re joined by Jody Freeman, the Archibald Cox Professor of Law at Harvard and the director of Harvard’s environmental and energy law program. She was an architect of the Obama administration’s landmark deal with automakers to accept carbon dioxide regulations.Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.Mentioned:The EPA Says Carbon Pollution Isn’t Dangerous.

Why We’re Worried About Electricity Prices

In the next few years, the United States is going to see the fastest growth in electricity demand since the 1970s. And that’s only the beginning of the challenges that our power grid will face. When you step back, virtually every trend facing the power system — such as the coming surge in liquified natural gas exports or President Trump’s repeal of wind and solar tax credits — threatens to constrain the supply of new electricity. On this week’s episode of Shift Key, Rob and Jesse talk about why they’re increasingly worried about a surge in electricity prices. What’s setting us up for an electricity shortfall? What does the recent auction in the country’s largest electricity market tell us about what’s coming? And what would a power shock mean for utility customers, the economy, and decarbonization? Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

How Sun and Wind Become Electricity

The two fastest-growing sources of electricity generation in the world represent a radical break with the energy technologies that came before them. That’s not just because their fuels are the wind and the sun.This is our third episode of Shift Key Summer School, a series of “lecture conversations” about the basics of energy, electricity, and the power grid. This week, we dive into the history and mechanics of wind turbines and solar panels, the two lynchpin technologies of the energy transition. What do solar panels have in common with semiconductors? Why did it take so long for them to achieve scale? And what’s an inverter and why is it so important for the grid of the future? Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

Climate Policy in America: Where We Go From Here

It’s official. On July 4, President Trump signed the Republican reconciliation bill into law, gutting many of the country’s most significant clean energy tax credits. The future of the American solar, wind, battery, and electric vehicle industries looks very different now than it did last year.On this week’s episode of Shift Key, we survey the damage and look for bright spots. What did the law, in its final version, actually repeal, and what did it leave intact? How much could still change as the Trump administration implements the law? What does this mean for U.S. economic competitiveness? And how are we feeling about the climate fight today? Jillian Goodman, Heatmap’s deputy editor, joins us to discuss all these questions and more. Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.

How Does a Power Plant Work?

Just two types of machines have produced the overwhelming majority of electricity generated since 1890. This week, we look at the history of those devices, how they work — and how they have contributed to global warming.This is our second episode of Shift Key Summer School, a series of “lecture conversations” about the basics of energy, electricity, and the power grid for listeners of all backgrounds. This week, we dive into the invention and engineering of the world’s most common types of fossil- and nuclear-fueled power plants. What’s a Rankine cycle power station, and how does it use steam to produce electricity? How did the invention of the jet engine enable the rise of natural gas-generated electricity? And why can natural gas power plants achieve much higher efficiency gains than coal plants?Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.
