    How to design a brand-new city

    03/13/2026 | 1h 12 mins.
    I’m back with part two of my conversation with Jan Sramek, founder of California Forever, about his plan to build a brand-new city in Solano County. We get into the nuts and bolts of the urban design, discuss affordability and sustainability, get into governance issues, and look forward to what might happen next.

    Is the brand new city in California for real?

    03/11/2026 | 1h 3 mins.
    In this episode, I’m joined by Jan Sramek to discuss California Forever, the much-debated proposal to build a brand-new, sustainably designed city in Northern California. We explore the urbanist vision at the heart of the project, including a street grid inspired by Barcelona superblocks, and address the elephant in the room — the stealthy land acquisitions and the billionaire backers. Is this an urbanist utopia in the making or a grandiose con job?

    The fate of fossil fuel systems in the "mid-transition"

    03/04/2026 | 1h 14 mins.
    If the world takes its climate targets seriously, the coming decades will see fossil fuel systems shrinking as clean energy systems grow. In this episode, I talk with associate professor Emily Grubert about the issues that may arise during this “mid-transition” period. She has fascinating new study on the physical and financial cliffs that fossil fuel systems may go over as they decline and reach their “minimum viable scale” — and argues that public ownership of these dying industries might be the only way to gracefully phase them out.

    What is PJM and why is everyone so mad about it?

    02/20/2026 | 1h 15 mins.
    PJM is the largest wholesale power market and transmission planning region in the US. Currently, it is stuck between a rock and a hard place: on one side, rising demand from data centers; on the other, a choked and congested interconnection queue that can’t keep pace. The result: rising prices and political discontent. I talk with Clara Summers of the Citizens Utility Board about how PJM can solve this dilemma and get prices under control.
