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.

    Even as he has torn down climate policy, Donald Trump has normalized the use of more powerful & aggressive tools of economic statecraft, like equity stakes in private companies, new federal authorities, and sovereign wealth funds. The Roosevelt Institute recently issued a collection of 17 essays exploring how a future administration could use the tools Trump has assembled for decarbonization. I talk with Todd Tucker, editor of and contributor to the volume, about these new industrial planning tools.

  • Making data centers flexible so they can serve the grid rather than stress it out

    Typically, AI data centers are large, inflexible loads that the grid has to build around, which is one reason utilities take so long to connect them. Emerald AI has designed a “digital brain” that can ramp down, move, or delay computing jobs in a data center on demand, making a data center a flexible asset to the grid. I talk with CEO Varun Sivaram about how the software works, what flexibility costs the compute, why it beats just installing batteries, whether utilities can enforce it, and what it would mean for clean energy.

    Chapters:

    00:00 – Introduction

    03:05 – Temporal, spatial, and resource flexibility

    06:26 – What Emerald Conductor touches on site

    08:35 – Who decides which workloads can flex

    10:55 – Who is liable when a job slows down

    13:45 – Who actually signs the contract

    14:49 – Larger and faster grid connections

    18:02 – Enforcing the flexibility promise

    19:05 – What broke in the demos, from bad nodes to slow telemetry

    26:41 – What flexing costs the compute jobs

    29:21 – Why not just use batteries, and the demand merit order

    35:44 – Training, inference, and substation-scale data centers

    40:23 – PJM, ERCOT, and legal enforceability

    44:50 – Renewables, gas, and consumer bills

  • Why can't utilities innovate?
    2026/08/21

    When it comes to innovative new grid technologies, every utility wants to be the third in line to try them. None of them want to be the first to take risks and iron out new processes. That's one reason grid-enhancing technologies, better software, and smarter internal procedures stay stuck in pilot purgatory, even as the industry faces the biggest buildout since rural electrification. PG&E's Quinn Nakayama and Microsoft's Hanna Grene discuss what's actually blocking utility innovation — and Quinn offers a novel proposal for paying someone to go first.

    Chapters:

    00:00 – Introduction

    03:44 – Why grid-enhancing technologies stall in the US

    07:54 – Selling grid software into utilities: what goes wrong

    11:08 – From a pipes-and-wires company to a technology company

    12:38 – Pilot program hell and the last 30 percent

    15:04 – Innovation as a bolt-on, and the three muscles

    17:47 – The digital spine, data quality, and smart meters

    23:56 – Org chart versus work chart

    25:09 – Strategy, structure, people, process, technology

    29:24 – Build, buy, and the ecosystem skill set

    36:15 – Data leakage, shadow AI, and paying twice

    41:12 – Why utility product cycles run five to seven years

    46:27 – Human in the loop, and EPRI's SAFERai.power

    49:06 – Advanced market commitments and the kingmaker problem

    53:22 – EPIC, and whether software counts as infrastructure

    01:00:05 – The CapEx incentive problem and final advice

    1:04:34 – Digital Infrastructure as Capital Spend

    1:06:53 – Final Advice
