PG&E, California's notoriously troubled utility, is trying to prove it can innovate, so I invited Quinn Nakayama, head of its new GRiD program, to explain how. We discuss its strategy of publicly outlining its problems to attract partners and its shift toward faster, more flexible interconnection for new loads like EVs and data centers.

The frantic buildout of AI data centers is threatening to overwhelm electric grids, but what if they could be part of the solution? I chat with Jeff Bladen of Verrus, a company designing data centers to be "good grid citizens" from the ground up. We discuss how their novel architecture, combining large-scale batteries with a more efficient internal power network, provides flexibility that helps utilities and allows more compute to be built with less grid impact.

In this episode, I chat with fellow energy nerd-turned-ag-reporter Michael Grunwald about agriculture’s climate impact. We explore the folly of biofuels, the promise of meat alternatives, and the central importance of increasing yields. While we can imagine a future of energy abundance, land is a zero-sum game — no one’s making more — so the choices here are uniquely difficult and important. This is a public episode.

In this episode, I'm joined by two of California's leading housing champions, Assemblymember Buffy Wicks and Senator Scott Wiener, to discuss their bills to reform the state's notorious environmental review law, CEQA. We explore how a well-intentioned 1970s environmental protection has become a tool for NIMBYs, unions, and even oil companies to delay or kill housing projects — and why the politics have finally shifted enough to make progress possible.

Washington state just passed one of the strongest transit-oriented development bills in the nation, and in this episode, I talk with Rep. Julia Reed and Alex Brennan from Futurewise about how they got it done. We discuss why building more housing near transit is so important, what this landmark legislation entails for density and affordability, and how it positions Washington as a leader in pro-housing reform.

On June 4, at a Canary Media event in Washington, DC, I sat down with Senator Martin Heinrich to dissect the GOP’s so-called “Big Beautiful Bill” — a sledgehammer aimed at the Inflation Reduction Act, public-lands protections, and US science. We talk about the handful of Republican votes that could still save key tax credits, why bipartisan permitting reform isn’t dead yet, and how the bill’s self-inflicted grid squeeze would jack up energy prices right when AI is poised to spike demand.

To hear more, visit www.volts.wtfThis week on "What the F is Happening" (periodic episodes in which we reluctantly discuss current events) we talk with Adrian Deveny, a former Senate aide who was in the trenches for the IRA's creation, about the House GOP's "Big Beautiful Bill." In its current form, it amounts to wholesale destruction of the last four years of climate policy. We ponder the bill's chances of becoming less catastrophic in the Senate amid the lack of meaningful pushback from the industries being kneecapped and the predictable folding of "moderate" Republican opposition.

In this episode, I talk with Catie Gould and Alan Durning of the Sightline Institute about the "dark matter" of urban land use: parking — specifically, the municipal parking mandates that help make housing more expensive and scarce. We discuss a landmark new parking reform bill in my home state of Washington, what it does and the coalition that made it possible, and point to other places where parking reform is coming soon.

I'm joined by “Texas Doug” Lewin to unpack the fascinating contradictions of a state that inadvertently became the nation's renewable energy powerhouse through a free market electricity system that its politicians now seem bent on strangling. Bills before the legislature would require solar and wind developers to also build gas plants, impose extreme setback requirements only on renewables, and potentially cripple the state's economy just as data centers drive unprecedented demand growth.

In this episode, I sit down with my old friend Sean Casten for a frank insider's take on the precarious state of clean energy policy amid our ongoing constitutional meltdown. We dive into the political knife fight over IRA tax credits (some Republicans support them), why transmission reform remains frustratingly partisan despite economic logic, and the fossil industry's fear of competition.
