Collectively, the electric stack (batteries, motors, chips, power electronics) has gotten about 99% cheaper since 1990. It is quietly remaking every machine that turns electricity into motion, heat, or work. Problem is, China makes most of it. Sam D’Amico, co-author of “The Electric Slide” and founder of Impulse Labs, is betting the US can still claim a piece of that stack. He’s starting with a battery-powered induction cooktop. We talk about why domestic manufacturing matters, what America would actually have to build to compete, and how Silicon Valley’s founder world really thinks about climate change, geoengineering included.

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

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.

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

What’s up with the new federal permitting reform bill? Oct 09, 2026

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

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

What’s up with heat-pump water heaters? Sep 30, 2026

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.

Chapters:

00:00 – Introduction

03:06 – Why water heaters

06:34 – How gas, resistance, and heat pump water heaters work

09:33 – Size and slow recovery: predictive heating and party mode

15:31 – Installation and vertical integration

22:19 – Cutting electric resistance backup

20:31 – What Reservoir builds and what it sources

23:41 – Tankless gas, virtual capacity, and the booster heater

27:11 – Recirculation, freeze protection, leak detection, and Legionella

32:03 – What it costs and what it saves

36:01 – Placement: small rooms, basements, and cold climates

42:37 – Noise and durability

48:19 – Demand response and virtual power plants

53:22 – A. O. Smith’s CO2 split system and Reservoir’s moat

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.

Chapters:

00:00 Introduction

02:26 Lessons from Powerwall and Span

05:33 What Pila is and how it works

07:14 How long a fridge runs on one battery

19:55 Who is actually buying Pila

23:00 Financing models and free batteries

27:04 Do the bill savings add up?

32:05 Why utilities want small batteries in VPPs

36:58 Pilots with Holy Cross Energy and Brooklyn SolarWorks

41:09 Solar pairing and the Pila mesh network

47:14 Camping batteries and built-in storage

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.

Chapters:

00:00 – Introduction

03:46 – What a DC media strategist actually does

09:50 – Republicans, Trump, and a narrow House majority

15:29 – Why tax cuts beat energy in the OBBBA fight

18:54 – Competing with China on AI without the electric stack

21:15 – Paying $4 billion to hand back offshore wind leases

28:07 – Red-state wind and the orders keeping coal plants open

32:52 – Clean energy trade groups and the building trades

38:41 – Gas as a bridge, and what longer term means

44:55 – Whether a half-gas trade group can serve clean energy

48:43 – A coherent clean vision against an incoherent coalition
