In this episode, I talk with Erik Steimle of Rye Development about the new wave of "closed loop" pumped-hydro storage projects. Unlike traditional systems that rely on rivers and dams, these projects use two artificial reservoirs — providing reliable long-duration storage without impacting natural waterways. We explore the economics of these billion-dollar facilities, their 100+ year lifespans, and how they compare to lithium-ion storage.

I'm joined by Eric Gimon to discuss "energy parks" — essentially large-scale microgrids that combine renewable generation, storage, and industrial loads behind a single grid connection. We explore how this model could accelerate clean energy deployment while creating new economic opportunities, despite some complex regulatory hurdles.

In this episode, I talk with Matt Traldi, co-founder of Greenlight America, about the fight for clean energy at the local level. We discuss how small groups of opponents are successfully blocking renewable projects across the country, and how his organization is working to turn the tide by mobilizing local supporters and giving them the tools to advocate effectively at critical government meetings.

In this episode, I revisit thermal energy networks with HEET's Zeyneb Magavi and Eversource's Eric Bosworth. What was once a novel concept - replacing gas networks with shared ground-source heat pumps - is now being piloted across the country. We explore the technology's remarkable efficiency and its potential to revolutionize heating and cooling — and give gas utilities a second life as thermal utilities.

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.

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.

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.

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.

In this episode, I talk with Kate Gordon, CEO of California Forward, about how climate change is breaking the insurance industry. We discuss why insurers are fleeing high-risk states, the limitations of government backstops, and the looming political and financial crisis as communities face hard choices about where people can safely live.

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.
