    How energy politics work inside DC

    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

    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

    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
    07:39 – The medium voltage power plane
    12:13 – UPS batteries vs. the big LFP battery
    17:27 – Priority aware capping and provisioned utility capacity
    22:31 – Why not buy the pieces off the shelf?
    25:42 – Duration: what happens when four hours runs out
    34:28 – Diesel backup and what customers ask for
    37:15 – How flexible is compute, really?
    42:37 – Noise, fans, and the sound studies
    48:42 – Water use and the 12 million gallon question
    52:19 – Industrial land and by-right zoning
    56:07 – Public opposition, recall petitions, and community benefits
    1:00:07 – Oregon, Salem, and the moratorium
    1:03:56 – Ride-through, NERC, and losing the moat
    1:07:11 – What V2 looks like

    Building a big, abundant, clean grid

    Jane Flegal has worked inside philanthropy at the Hewlett Foundation, industrial emissions policy at the Biden White House, and carbon-removal market development at Frontier; she's now a senior fellow at the Searchlight Institute, writing some of the smartest climate policy analysis around. We cover a lot of ground: industrial policy versus market approaches, what the IRA got right and wrong, philanthropy's proper role, data centers and the case for an infrastructure fund, and behind-the-meter gas, among other things. This is a long one, and spicy!
    Chapters:
    00:00 – Introduction
    03:11 – Flegal's thesis: building a clean grid fast enough to power growth
    06:29 – Why she rejects degrowth
    09:27 – The Roosevelt essay: climate as more than a market failure
    13:30 – Why clean energy underuses its political muscle
    15:24 – Industrial policy and the green spiral theory of change
    20:40 – Was IRA the right approach?
    22:12 – Lily Bermel's paper and the fight over what survived
    23:21 – What she would have done differently under IRA
    30:11 – Philanthropy, Silicon Valley, and what government is for
    33:29 – The epistemic crisis inside environmental NGOs
    39:09 – The abundance movement and what each faction misses
    44:16 – What establishment Democrats get wrong on climate
    46:06 – Why issue polling misleads
    50:34 – Republicans and the Cold War analogy
    52:47 – Data centers and the American Grid Infrastructure Fund
    59:13 – Affordability politics and who pays for the grid
    1:08:14 – Emissions, behind-the-meter gas, and flexible load
    1:13:57 – The clean firm debate: storage plus transmission?
    1:20:14 – Capacity markets, ERCOT, and the case for planning
    1:24:32 – Utility incentives, public power, and affordability fixes
    1:35:55 – Permitting reform and the land footprint asymmetry
    1:41:05 – NEPA reform and the political window

    Is there way more conventional geothermal than we thought?

    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
    54:20 – Policy dependence and public lands
    58:11 – What's next for Zanskar
