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.

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.

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.

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.

Volts published seven conversations in September, which is a lot for anyone to listen to. We’ve rounded up the highlights into less than an hour. Enjoy!

Heat pump water heaters use a fraction of the energy of conventional electric resistance heaters — which use more electricity in a year than an EV — but they're only 2 percent of the market, mainly because they tend to cost more, be slow and loud, and require a plumber and an electrician. Reservoir is a Boston company trying to fix all that, with a smarter, quieter machine and its own plumbers. I talk with CEO Luke Winston-Almanzar about how it works, what it costs, and its potential role in demand response programs.

Home batteries like the Tesla Powerwall are nice, but what about people who can’t afford them, or renters who aren’t allowed to install them, or people who just don’t want the hassle of dealing with a permit and an electrician? A company called Pila is selling small (1.6 kWh) batteries that simply plug into a normal electrical socket. They can serve as backup for a refrigerator or other appliance in the event of a blackout, but they can also “mesh” with one another to form a network, pair with rooftop solar, or participate in VPP programs. CEO Cole Ashman explains the value proposition.

1:00:10 Clean energy as invisible infrastructure

Back in 2011, I wrote that fossil fuel interests had a much better media game than clean energy. My example was Frank Maisano, a media relations guy for coal utilities and the natural gas industry. Thirty years on, he’s still at it — still writing his newsletter, still connecting reporters to sources, still better at it than anyone on the clean side (sigh). So I’m finally talking to him about it: clean energy trade groups nobody in Washington fears, Trump’s daft efforts to kill renewables, the PAC picking off dirty-energy Republicans, permitting and data center fights, and the climate denial shop he worked for in the ‘90s. Spoiler: he regrets nothing.
