Conventional geothermal energy is limited to specific hot spots, but “closed-loop” geothermal, by going deeper and confining water to sealed boreholes, promises to work almost anywhere; it amounts to building a giant radiator, deep underground. I’m joined by Jeanine Vany and Mark Fitzgerald of pioneering closed-loop startup Eavor to discuss their newly operational plant in Germany and the many advantages of a system that requires no fracking and consumes no water.

In this episode, I’m joined by Kate Slevin of the Regional Plan Association to discuss the triumphant first year of congestion pricing in Manhattan. We explore how the program defied its critics by boosting business and pedestrian traffic while reducing gridlock, without evident traffic spillover onto adjacent streets. We also cover the money that’s been raised for public transit and what the future holds for the congestion relief zone.

Hawaii Senator Brian Schatz joins me to discuss the energy policy landscape facing Democrats and how they should respond. We touch on the shift in messaging from “climate” to “affordability,” current Congressional Republican efforts on permitting reform in light of Trump’s anti-renewables crusade, the role of green groups in climate politics, and much more.

Why can Australian homeowners get rooftop solar installed in a week or less, for roughly 50 cents a watt, while Californians pay $3.30/w and wait months for interconnection? In this episode, I ask inimitable Australian energy expert Saul Griffith to walk us through the entire process — from quote to interconnection — to pinpoint exactly where the US system is broken and how we could fix it.

The problem of misinformation in the current age, argues political scientist Samuel Bagg, is not that reliably truth-producing institutions and practices don’t exist, but that people have ceased to trust them. Changing that requires something deeper than factchecking or media literacy. It’s a matter of social identity, and solving it will mean reconfiguring the social identity landscape. I talk with Bagg about that daunting conclusion and its implications for democracy.

Senator Ruben Gallego (AZ) joins me to discuss his new energy plan, which combines elements of the Inflation Reduction Act with a new focus on permitting reform and small modular nuclear reactors. We get into all of it, from the promise of nuclear energy to the role community consultation.

In this episode, Aliya Haq unpacks how her two decades in the climate movement have reshaped her view of what works. After six years working at Bill Gates’ Breakthrough Energy initiative, she has launched the Clean Economy Project, which will push for grid upgrades, market reforms, and innovation to make clean energy cheaper and more abundant. We wrestle with the politics of it all.

I’m joined by Brian Turner and Kathleen Staks to unpack the details of the newly authorized Regional Organization for Western Energy (ROWE), a unique “à la carte” RTO designed to unify the western US grid without trampling on state independence. We discuss the transition from the existing imbalance market to a full day-ahead market, the safeguards built into the bylaws to protect state clean-energy policies, and the politics of getting 38 separate balancing authorities to cooperate.
