S3E5 - Live From New York Climate Week: The AI and Electricity Moment
Artificial intelligence is helping to drive up electricity demand in America. Energy costs are rising, and utilities are struggling to adjust. How should policymakers — and companies — respond to this moment? On this special episode of Shift Key, recorded live at Heatmap House during New York Climate Week, Rob leads a conversation about some potential paths forward. He’s joined first by Representative Sean Casten, the coauthor of a new Democratic bill seeking to lower electricity costs for consumers. How should the grid change for this new moment, and what can Democrats do to become the party of chea...

S3E4 - Nobody in the West Knows How to Respond to the ‘Electrotech Revolution’
A new stack of electricity technologies — including solar panels, batteries, electric vehicles, and power electronics — seem to be displacing fossil fuels across China and the developing world. Are we watching an irresistible technological revolution happen? Or is something weirder going on — something that has far more to do with China’s singular scale and policy goals than physics and economics? Kingsmill Bond argues that a global electrotech revolution has already begun — and that it will soon sweep Europe and the United States, too. Bond is an energy strategist at Ember, a London-based electricity data think tank. He previous...

S3E3 - What J.P. Morgan’s Chief Climate Advisor Is Telling Energy Startups
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...

S3E2 - Utility Regulation Really Sucks
Electricity is getting more expensive — and the culprit, in much of the country, is the poles and wires. Since the pandemic, utility spending on the “last mile” part of the power grid has surged, and it seems likely to get worse before it gets better.How can we fix it? Well, we can start by fixing utility regulation. On today’s episode of Shift Key, Rob and Jesse talk about why utility regulation sucks and how to make it better. In Europe and other parts of the world, utilities are better at controlling their cos...

S3E1 - What Carbon Dioxide Has to Do With the Meaning of Life
How did life first form on Earth? What does entropy have to do with the origins of mammalian life — or the creation of the modern economy? And what chemical process do people, insects, Volkswagens, and coal power plants all share?On this week’s episode of Shift Key, Rob chats with Peter Brannen, the author of a new history of the planet, The Story of CO2 Is the Story of Everything. The book weaves together a single narrative from the Big Bang to the Permian explosion to the oil-devouring economy of today by means of a singl...

S2E54 - Shift Key Classic: How to Hook Up More Power Plants
Shift Key is off for Labor Day, so we’re re-running this classic episode.For the first time in 15 years, American electricity demand is rising again as new data centers, factories, and electric vehicles come online. The easiest option is to meet that new demand with new supply — new power plants. But in many parts of the country, it can take years to hook up new wind, solar, and batteries to the grid. The reason why is a clogged and broken system called the interconnection queue. On this week’s episode of Shift Key, whic...

S2E53 - This Is What It’s Like to Run a Power Grid
So far on Shift Key Summer School we’ve covered how electricity gets made and how it gets sold. But none of that matters without the grid, which is how that electricity gets to you, the consumer. Who actually keeps the grid running? And what decisions did they make an hour ago, a day ago, a week ago, five years ago to make sure that it would still be running right this second? This week on Shift Key, Rob and Jesse chat with Mark Rothleder, senior vice president and chief operating officer of the California Independent Sys...

S2E52 - How Electricity Markets Work
Most electricity used in America today is sold on a wholesale power market. These markets are one of the most important institutions structuring the modern U.S. energy economy, but they’re also not very well understood, even in climate nerd circles. And after all: How would you even run a market for something that’s used at the second it’s created — and moves at the speed of light? On this week’s episode of Shift Key Summer School, Rob and Jesse talk about how electricity finds a price and how modern power markets work. Why run a p...

S2E51 - 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 joine...

S2E50 - 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 elec...

S2E49 - 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 lon...

S2E48 - 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...

S2E47 - 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 us...

S2E46 - What Is a Watt?
What is the difference between energy and power? How does the power grid work? And what’s the difference between a megawatt and a megawatt-hour? On this week’s episode, we answer those questions and many, many more. This is the start of a new series: Shift Key Summer School. It’s a series of introductory “lecture conversations” meant to cover the basics of energy and the power grid for listeners of every experience level and background. In less than an hour, we try to get you up to speed on how to think about energy, power, hors...

S2E45 - If You Care About Food, You Have to Care About Land
Food is a huge climate problem. It’s responsible for somewhere between a quarter and a third of global greenhouse gas emissions, but it concerns a much smaller share of global climate policy. And what policy does exist is often … pretty bad.On this week’s episode of Shift Key, Rob and Jesse talk with Michael Grunwald, the author of the new book We Are Eating the Earth. It’s a book about land as much as it’s a book about food — because no matter how much energy abundance we ultimately achieve, we’re stuck with the amoun...

S2E44 - It’s Easiest to Electrify This Type of Truck
You might not think that often about medium-duty trucks, but they’re all around you: ambulances, UPS and FedEx delivery trucks, school buses. And although they make up a relatively small share of vehicles on the road, they generate an outsized amount of carbon pollution. They’re also a surprisingly ripe target for electrification, because so many medium-duty trucks drive fewer than 150 miles a day.On this week’s episode of Shift Key, Rob and Jesse talk with John Henry Harris, the cofounder and CEO of Harbinger Motors. Harbinger is a Los Angeles-based startup that sells electr...

S2E43 - A New Grand Theory of Why Decarbonization Is So Hard
Why has it been so hard for the world to make progress on climate change over the past 30 years? Maybe it’s because we’ve been thinking about the problem wrong. Academics and economists have often framed climate change as a free-rider or collective action problem, one in which countries must agree not to emit greenhouse gases and abuse the public commons. But maybe the better way to understand climate action is as a fight that generates winners and losers, defined primarily by who owns what. On this week’s episode of Shift Key, Rob and Jesse t...

S2E42 - The Supreme Court’s Double-Edged Change to Permitting Law
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 yea...

S2E41 - Shift Key Classic: The World Will Miss 1.5C. What Comes Next?
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 be...

S2E40 - How the GOP Megabill Would Reshape the U.S. Energy Economy
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 Unive...
