  • 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

  • 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.

  • 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

  • What’s up with heat-pump water heaters?
    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

    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

  • Do small residential batteries make sense?
    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

    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

    09:28 Fire risk, LFP chemistry, and New York City

    16:02 Why the price went up, and cost per kilowatt hour

    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

  • How energy politics work inside DC
    This is a free preview of a paid episode. To hear more, visit www.volts.wtf

    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

    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

    51:14 – Do the green groups still scare anyone

    55:18 – Permitting reform and the Whitehouse-Capito path

    59:46 – Data centers, animal spirits, and the midterms

    1:06:48 – The revenge PAC, and whether it is working

    1:12:31 – Congress, the courts, and what Democrats could do

    1:18:53 – COP, climate change, and the client he would turn down

  • How to build a more flexible, quieter, less obnoxious data center
    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

    Verrus is building data centers designed to address every objection the public has raised: they use batteries instead of diesel generators, which makes them grid assets that help hold down power prices; they use closed-loop cooling, which uses a tiny fraction of the water; their equipment is quieter; and as a bonus, they squeeze more servers into the same grid connection. Yet both of Verrus’s proposed sites, in Michigan and Oregon, are mired in fierce local opposition. In this episode, CEO Nelson Abramson walks through the engineering — and the politics that the engineering hasn’t quite solved.

    Chapters:

    00:00 – Introduction

    02:43 – Three decades in data centers

    05:05 – What a Verrus data center looks like

  • Is there way more conventional geothermal than we thought?
    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

    Zanskar argues that the US is badly underestimating its conventional geothermal resources — that there are far more undiscovered hydrothermal systems, and that each one can produce far more power, than people think. They think AI can help find those resources, and they have drilled three sites to back it up, including a “blind” discovery in Nevada with no surface signs and no prior exploratory wells. If they're right, terawatts of firm, carbon-free power are reachable with off-the-shelf drilling technology. Co-founders Carl Hoiland and Joel Edwards make the case.

    Chapters:

    00:00 – Introduction

    03:29 – Heat, permeability, and how resources have been found

    04:49 – Why conventional geothermal stalled, and why the estimate is stale

    09:22 – Applying AI to old exploration data

    11:10 – The data Zanskar works with

    13:09 – Models, field testing, and the feedback loop

    15:02 – How much more resource is really out there

    20:22 – Lightning Dock: reviving a written-off field

    22:14 – What has changed in drilling technology

    28:37 – Pumpernickel and the permeability question

    31:08 – Natural permeability vs. enhanced geothermal

    34:21 – Big Blind, the first blind discovery in 30 years

    37:09 – Improving the models to keep getting better

    40:51 – Financing exploration: the development capital facility

    44:38 – The NV Energy PPA and data center demand

    47:42 – The skeptical case and geographic limits
