Why can Australian homeowners get rooftop solar installed in a week or less, for roughly 50 cents a watt, while Californians pay $3.30/w and wait months for interconnection? In this episode, I ask inimitable Australian energy expert Saul Griffith to walk us through the entire process — from quote to interconnection — to pinpoint exactly where the US system is broken and how we could fix it.

The problem of misinformation in the current age, argues political scientist Samuel Bagg, is not that reliably truth-producing institutions and practices don’t exist, but that people have ceased to trust them. Changing that requires something deeper than factchecking or media literacy. It’s a matter of social identity, and solving it will mean reconfiguring the social identity landscape. I talk with Bagg about that daunting conclusion and its implications for democracy.

Senator Ruben Gallego (AZ) joins me to discuss his new energy plan, which combines elements of the Inflation Reduction Act with a new focus on permitting reform and small modular nuclear reactors. We get into all of it, from the promise of nuclear energy to the role community consultation.

In this episode, Aliya Haq unpacks how her two decades in the climate movement have reshaped her view of what works. After six years working at Bill Gates’ Breakthrough Energy initiative, she has launched the Clean Economy Project, which will push for grid upgrades, market reforms, and innovation to make clean energy cheaper and more abundant. We wrestle with the politics of it all.

I’m joined by Brian Turner and Kathleen Staks to unpack the details of the newly authorized Regional Organization for Western Energy (ROWE), a unique “à la carte” RTO designed to unify the western US grid without trampling on state independence. We discuss the transition from the existing imbalance market to a full day-ahead market, the safeguards built into the bylaws to protect state clean-energy policies, and the politics of getting 38 separate balancing authorities to cooperate.

Why is a deregulated state like Illinois suddenly embracing central planning? In this episode, I talk with Kady McFadden and John Delurey about the state’s decision to empower its utility commission to directly procure clean energy. We discuss why capacity markets are too slow for the current environment and their strategy of aggressively framing renewables and storage not just as green, but as the only “fast and cheap” way to protect ratepayers from price spikes.

With load growth projections all over the map and politicians zeroing in on high electricity prices, I take a step back in this audio essay to ask how we should build the grid in the face of massive uncertainty. The answer lies in modular, distributed technologies that strengthen the system regardless of whether the AI bubble eventually bursts.

Will cheap, DIY solar reach American renters? In Germany, millions of people plug solar panels directly into wall outlets like any other appliance, but in the US, red tape makes it ludicrously costly. I chat with Cora Stryker of Bright Saver about how “balcony solar” (AKA “plug-in solar”) is booming in Europe and making its way to America, starting in Utah. We discuss the technical and safety issues, the regulatory hurdles, and the solar “gateway drug” effect.

Energy strategist Kingsmill Bond joins me to explain why the transition to “electrotech” is unstoppable, whether or not politicians care about climate change. It’s not the reduced emissions, it’s physics (electrotech is more efficient) and economics (it’s cheaper). Despite political headwinds in the US, China and emerging economies are racing ahead with electrification and sector after sector is seeing peak fossil fuel consumption. There’s no stopping it: electrons will triumph over

Environmentalism has typically focused on outdoor air quality, but climate change is pushing more people indoors more of the time, even as airborne pathogens and wildfire smoke challenge indoor air quality. I discuss the fight for better indoor air with Dr. Georgia Lagoudas, who recently coordinated a global pledge declaring it a basic human right. We dig into what pollutes indoor air, the technologies that can keep it clean, and the enormous social and economic benefits clean air in schools.
