In this episode, I chat with Dr. Sarah Kapnick about the core of climate science and the wild variables that have emerged in the last decade. We discuss the “accidental geoengineering” experiment of reducing shipping aerosols, the newfound ability to pinpoint methane leaks from space, and the legal implications of being able to attribute financial losses to climate change.

How does a small, mountainous island with no interconnections and a massive industrial load clean up its grid? In this episode, I speak with Yeh-Tang “Ricky” Huang about the technical and political bottlenecks holding back Taiwan’s energy transition. We explore why the country has struggled to deploy wind and solar, the realistic prospects for advanced geothermal, and the absolute necessity of demand-side flexibility in such a constrained system.

Why do so many influential voices spend their time policing the manners of the left while the right dismantles democracy? In this episode, Michael Hobbes — cohost of the much-celebrated “If Books Could Kill” podcast — joins me to discuss the “reactionary centrist,” a type of commentator who believes that both sides are to blame for everything and demonstrates this by spending every waking moment scolding Democrats.

Rooftop solar costs nearly three times as much in the US as it does in Australia, largely due to the "paperwork tax" imposed by thousands of fragmented local jurisdictions. I talk with Nick Josefowitz of Permit Power and solar veteran Andrew Birch about how to slash these soft costs through automated permitting and standardized interconnection. We discuss how these bureaucratic fixes could unlock dirt-cheap energy for American families without the need for subsidies.

Everyone is talking about virtual power plants, but as I discuss with EnergyHub CEO Seth Frader-Thompson, not all VPPs are created equal. We get nerdy on the various stages of VPP maturity and the specific technical requirements that VPPs must meet to truly compete with conventional power plants rather than just acting as “enhanced demand response.”

I’In this episode, I chat with Swedish tech entrepreneur Jonas Birgersson about his radical plan to apply the architecture of the internet—packet switching, buffering, and decentralized routing—to the electricity grid. We explore how his “EnergyNet” concept uses power electronics to create galvanically separated microgrids that stop cascading failures and allow neighbors to share power directly. It is a mind-bending look at how treating electrons like data could lead to unlimited energy for a low fixed fee.

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.
