    The promise of residential VPPs

    In this episode, I speak with Ben Brown, CEO of Renew Home, about the company's groundbreaking 1-gigawatt virtual power plant deal with NRG Energy in Texas. It will be the nation’s largest VPP, leveraging existing smart thermostats to control millions of residential HVAC systems. We discuss customer experience, data privacy, and the ability of VPPs to rapidly scale to meet rising electricity demand.

    Should we put utilities in charge of distributed energy?

    In this episode, I speak with Pier LaFarge, CEO of Sparkfund, who challenges the traditional antagonism between utilities and distributed energy advocates. While investor-owned utilities have long been seen as obstacles to clean energy adoption, LaFarge argues that they're actually essential to scaling DERs in an era of explosive electricity demand.

    Time to stop taking hydropower for granted?

    In this episode, I speak with Malcolm Woolf and Connor Nelson about hydropower's underappreciated role in America's clean energy landscape. While providing most of our energy storage and thus supporting solar and wind deployments, hydropower faces significant challenges, with a decade-long relicensing processes and inadequate market compensation. We discuss why preserving and expanding this reliable, clean firm energy source is crucial as we transition to renewables.

    Can we avoid the enshittification of clean-energy tech?

    In this episode, I chat with author Cory Doctorow about "enshittification," his viral term for how digital platforms and smart technologies inevitably get worse over time. We explore how monopoly power, aggressive IP protections, and lax privacy law enable companies to capture and exploit users — and what that might mean for the clean energy transition as our homes and vehicles become increasingly software-dependent.

    Checking in on local and state climate races

    In this episode, I talk with Caroline Spears of Climate Cabinet about the results of the state and local climate races her organization tracked in 2024. We discuss the importance of these often-overlooked state and local races for climate progress, the challenges of the current political information environment, and Climate Cabinet's strategy for building power at the state level through 2030 and beyond.

    Electrifying big trucks

    In this episode, I talk with Ray Minjares of ICCT and Jacqueline Torres of Forum Mobility about the electrification of heavy trucks, from drayage at ports to long-haul big rigs. We dig into charging challenges, innovative financing models, and the massive pollution cuts possible by transitioning fleets. Electric trucks are here — but they need the right policies and partnerships to scale.

    Dan Savage on blue America in the age of Trump

    In this episode, I talk with activist, sex advice columnist, and progressive journalist Dan Savage about the legacy of “The Urban Archipelago,” a groundbreaking piece he commissioned and edited two decades ago in the wake of GW Bush’s reelection, urging Democrats to embrace cities as their political base and future. We explore how NIMBY-captured Democratic city leadership has stifled urban potential — and why improving and growing cities isn’t just policy; it’s party building.

    Residential solar is becoming residential solar + storage + VPP

    In this episode, I chat with Sunrun CEO Mary Powell about how residential solar is evolving into much more than just panels. We dive into Sunrun’s expansion as a “clean energy lifestyle” brand, Mary’s belief in a customer-led energy transition, and alternatives to the tech bros' virile obsession with nuclear power.

    How railroads could boost the US energy transition

    In this episode, I talk with Bill Moyer, founder of the Reconnect America campaign, about the huge, untapped potential of U.S. railroads to support the clean energy transition. Bill makes the case that our privately owned rail system, focused on short-term profits, is missing out on big public benefits—like shifting freight from roads to rails, reducing emissions, and even using rail corridors to carry high-voltage transmission lines for renewable energy.

    How is electrification going?

    In this episode, I chat with Ari Matusiak, co-founder and head of Rewiring America, which recently received a $2 billion grant from the feds to take home electrification mainstream. We dig into the practical challenges — getting local contractors on board, simplifying rebate access — and the enormous opportunities.
