    Are utilities making too much money?

    2/11/2026 | 1h 15 mins.
    Utilities and their regulators are often protected by a "force field of tedium," but in this episode, I pierce the veil to discuss the complex machinery of utility profit-making. I’m joined by Joe Daniel of RMI to unpack the critical distinction between "return on equity" and "cost of equity," and why the former is almost always higher than necessary. We discuss how regulators can close this gap to lower consumer costs without hindering essential grid upgrades.

    So, how's the climate doing?

    2/06/2026 | 1h 4 mins.
    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.

    Taiwan's energy dilemma

    2/04/2026 | 1h 9 mins.
    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.

    All about "reactionary centrism"

    1/30/2026 | 1h 48 mins.
    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.

    How to make rooftop solar power as cheap in the US as it is in Australia

    1/28/2026 | 1h 8 mins.
    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.
