Volts is a podcast about leaving fossil fuels behind. I've been reporting on and explaining clean-energy topics for almost 20 years, and I love talking to politicians, analysts, innovators, and activists about the latest progress in the world's most important fight.

Can distributed energy work around American utilities?
This is a public episode. If you'd like to discuss this with other subscribers or get access to bonus episodes, visit www.volts.wtf/subscribe American homes are filling up with batteries, EVs, and smart thermostats that could be coordinated to make the grid cheaper and more reliable — but almost none of them are. To understand why, it helps to watch what happens when the company best in the world at this tries to do it here. In Britain, Octopus Energy has built a giant virtual power plant out of its customers' devices. In the US, it has spent six years running into walls. Now it’s bought Uplight, which runs customer programs for 85 utilities. I talked with Nick Chaset, who runs both, about what's in the way and whether distributed energy can ever scale with US utilities … the way they are. Chapters: 00:00 – Introduction 02:02 – Octopus’s past year and the Uplight investment 05:18 – What makes the UK market work for Octopus 11:12 – Texas: fast growth, flattened volatility 14:57 – Will flexibility put itself out of business? 19:16 – Why Octopus stays out of Pennsylvania and New York 22:17 – Does residential retail competition have a future? 24:41 – Why utility programs trail Octopus on participation 32:17 – The demand stack and what planners can count on 39:11 – Kraken, Uplight and the overlap 46:04 – Consumer protection and the aggregator model 51:17 – Data centers and the social license to operate 55:11 – Do we need dynamic pricing? 58:30 – Five years out

What’s up with Denmark?
This is a public episode. If you'd like to discuss this with other subscribers or get access to bonus episodes, visit www.volts.wtf/subscribe Denmark gets a large share of its power from wind and other renewables and has cut its emissions roughly in half since 1990, but independent analysts doubt it will hit its 70 percent target for 2030. Kristian Jensen, CEO of Green Power Denmark and a former Danish minister of taxation, foreign affairs, and finance, argues the next stage is electrifying how Denmark uses energy: heat, transport, and industry. I talk with him about district heating and heat pumps, EVs and vehicle-to-grid, municipally owned grid companies and hourly power prices, biomass, carbon capture, power-to-X, solar’s “fields of iron” backlash, a grid oversubscribed with data center requests (an October 1 agreement has since put most data centers at the back of the queue), and whether the country’s political consensus will hold. Chapters 00:00 – Introduction: Denmark and industrial symbiosis 02:44 – Is the 70% target for 2030 out of reach? 06:24 – Carbon capture and storage, and the peatlands lag 09:57 – Why electrification has lagged: biomass and wood pellets 14:45 – Few batteries, many interconnectors 16:48 – Data centers and the grid-connection prioritization bill 21:34 – Municipally owned grid companies 24:32 – Smart meters, hourly prices, and thermal batteries 28:40 – The solar backlash and local ownership 35:04 – Agrivoltaics and biodiversity 37:24 – District heating: heat pumps, geothermal, and finance 43:24 – The EV transition and vehicle-to-grid 47:45 – Road pricing and fiscal room 50:07 – Power-to-X and eSAF 54:21 – Can Denmark build enough clean power? 57:12 – Will the political consensus hold?

Checking back in with Greenlight America
This is a public episode. If you'd like to discuss this with other subscribers or get access to bonus episodes, visit www.volts.wtf/subscribe On this episode, recorded live at Climate Week NYC, I talk with Matt Traldi. He’s the founder and CEO of Greenlight America, which finds the local meetings where clean energy’s fate is being decided and recruits supporters to attend. Traldi argues that siting and permitting approvals turn on who shows up, and that local partners, conservative groups included, outperform outside advocates. We discuss how to measure impact, recent wins and losses, blue-state resistance, data center backlash, and Greenlight’s growth. Chapters: 00:00 – Introduction 02:09 – What Greenlight does and why Matt started it 04:41 – How Greenlight finds the decisions that matter 07:27 – Growth, and the tax credit deadline sprint 13:38 – Who shows up to local hearings 19:39 – Winning in conservative communities 22:35 – Bodies in the room, measuring impact, and win rates 27:46 – Losses, wins, and “there is no bag” 32:44 – Blue-state obstacles and organized opposition 36:31 – When data center backlash spills over onto clean energy 42:31 – Which projects Greenlight won’t back 45:38 – Lessons from housing and growing an organization 50:17 – Audience Q&A: disinformation and state permitting reform 54:39 – Audience Q&A: developers and elections 59:30 – Audience Q&A: funding local groups and designing community input

What’s up with the new federal permitting reform bill?
This is a public episode. If you'd like to discuss this with other subscribers or get access to bonus episodes, visit www.volts.wtf/subscribe The proposed bipartisan federal permitting bill is 417 pages filled with extremely consequential provisions that have left the climate community some mix of excited, infuriated, and confused. In an attempt to bring some clarity, I asked Daniel Palken of Arnold Ventures, a veteran of Senate permitting fights, to walk through what’s in it. We cover the blockbuster transmission reforms, the rule making data centers pay more than their share of grid costs, the wins for geothermal, and the fossil carve-outs. Then we get into NEPA reforms that render the act toothless, limits on state water permits, and the permit-certainty sections that have lawyers worried about “forever permits.” And finally: whether it restrains Trump, why Democrats shouldn’t wait for a better deal, what the modeling says about emissions impacts, and Daniel’s odds of passage. This is a long one, folks. Buckle up. Chapters: 00:00 – Intro: the bipartisan permitting bill 04:15 – Why permitting reform matters 12:23 – Agency staffing and capacity 16:59 – Past permitting attempts 20:26 – Transmission 1: planning and federal backstop 28:28 – Transmission 2: who pays and grid upgrades 38:17 – Data centers 1: paying more for grid access 43:20 – Distributed energy and geothermal 49:06 – Oil, gas, and mining provisions 57:06 – Data centers 2: will they go off-grid? 1:00:19 – NEPA 1: courts can’t halt projects 1:08:57 – NEPA 2: the main objections 1:17:10 – State water permits 1:23:35 – Endangered species 1:27:37 – Permit certainty 1: limits on revoking permits 1:36:43 – Permit certainty 2: lawsuits and damages 1:48:12 – Politics 1: Trump’s wind blockades 1:52:57 – Politics 2: why not wait for a better deal? 1:58:33 – Politics 3: elections, courts, and modeling 2:10:57 – Politics 4: next steps and odds of passage

The grueling fight to pass the Inflation Reduction Act
This is a public episode. If you'd like to discuss this with other subscribers or get access to bonus episodes, visit www.volts.wtf/subscribe On September 14, I sat down with Leah Stokes in front of a live audience at Seattle’s Town Hall to talk about her new book, The Carbon Wave. It’s an insider account of how the Inflation Reduction Act got made, braided with the story of the high-risk twin pregnancy she went through while helping to make it. We get into why electrification is the heart of decarbonization, the enduring mystery of what’s going on in Joe Manchin’s head, what it means to trade your carbon footprint for a carbon wave, and how much of the IRA survives. It was followed by questions from the audience. Chapters: 00:00 – Welcome and housekeeping 03:05 – The twins, the NICU, and writing the book 08:51 – Carbon footprint vs. carbon wave 13:39 – Sam Ricketts and 100% clean electricity 18:13 – Why electricity is the core of the solution 23:28 – Utilities and the politics of change 26:18 – Tech companies and data centers 29:11 – Inside the Manchin negotiations 33:57 – Why Manchin got to yes 38:46 – Trump, setbacks, and where things stand 42:55 – Clean energy politics and the global shift 46:25 – Audience Q&A: the transmission gridlock 48:59 – Institutions, speed, and structural reform 53:27 – If Democrats win the House, what next 55:43 – Permitting reform 59:06 – State utilities, coal, and getting involved
