Do small residential batteries make sense? 23 sept. 202601:05:43
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.

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:

How to build a more flexible, quieter, less obnoxious data center16 sept. 202601:14:47
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

Building a big, abundant, clean grid11 sept. 202602:00:45
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

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!

Is there way more conventional geothermal than we thought? 09 sept. 202601:04:30
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

How to respond to disinformation about clean energy, at scale02 sept. 202601:11:49
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

Disinformation about clean energy is showing up everywhere — online after every blackout, at county commission meetings about siting new projects, in regulatory dockets stuffed with fake comments. GoodPower, which combines a C3 education arm with a C4 advocacy arm, is trying to fight back with a network of thousands of content creators, rapid-response campaigns around storms and grid failures, and an AI tool that detects manufactured public comments. I talk with CEO Leah Qusba about what they've tried, what they've measured, and what actually works.

Chapters:

Could we use Trump's tricks to make good green policy?28 août 202601:08:44
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

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 out26 août 202600:53:24
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

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

Why can't utilities innovate?21 août 202601:11:59
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

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

He helped Uruguay decarbonize. Can he help other countries do the same?19 août 202601:02:13
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

Ramón Méndez Galain helped Uruguay decarbonize its grid (today it’s 98% fossil-free) while keeping the utility public and letting private capital foot the bill. Now he’s trying to export the same playbook across the global South. We talk through how Uruguay pulled it off — the hydro “battery” for wind & solar “baseload,” the cross-party political deal, the market redesign — and what actually transfers to countries without the same advantages. We also discuss why, seven years on, no other country has followed Uruguay’s path.

Can public EV chargers be as reliable as gas stations? 14 août 202601:01:56
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

As the U.S. EV market slows and federal charging support recedes, IONNA, a fast-charging network backed by eight major automakers, is still expanding. On Volts, CEO Seth Cutler makes the case that public charging is entering a new phase focused on reliability and customer experience, but the economics remain difficult, with low utilization and demand charges squeezing margins. With roughly 1,300 bays live and a target of 30,000, IONNA is testing whether a multi-brand network can offer a Tesla-like charging experience while building a sustainable business.

Chapters:

00:00 – Introduction: can public EV charging be as reliable as a gas station?

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

Last year I did a pod on Montana’s surprising burst of bipartisan housing legislation. Turns out Idaho was watching. This year its legislature passed six housing bills of its own (two others failed). Republican state Sen. Ben Toews and Democratic state Rep. Megan Egbert join me to walk through what passed, what didn’t, and what they gave away to get it done — plus the property tax cap that quietly works against all of it, and why duplexes turned out to be the red line.

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

Could the US grid be brought down by Chinese hackers? To find out, I talked with Patrick Miller, who helped write the cybersecurity rules for the bulk power system and became the first person with federal authority to enforce them. We get into what's actually been hacked, why those "rogue devices" in Chinese inverters are less sinister than they sound, and why squirrels still do more damage than hackers.

What should state policymakers do about data centers?05 août 202601:03:26
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

State legislatures are writing data center rules faster than they can verify the demand forecasts underneath them. Fifteen states accounted for 80 percent of data center electricity demand in 2023, a single hyperscale campus can arrive as 15 to 20 percent of a utility's demand, and the transmission to serve it takes five to 15 years to build. On this episode of Volts, David Roberts works through Climate Cabinet's Taming Data Center Turmoil series with Saleem Chapman, who leads the group's electricity affordability policy work, on why Georgia's regulated utility, PJM's capacity market, and ERCOT's competitive market each left ratepayers holding the risk, and what a state can require before it approves a project, while the facility operates, and after the deal is done.

Best of July 202602 août 202600:45:46

Volts published eight conversations in July on subjects with nothing obvious in common: an Arizona utility board election, Minnesota smart meters, land value taxes in Spokane, silicon battery anodes. Yet six of them arrived at the same constraint. What stops energy infrastructure from getting built in the United States is more often written into law than into physics. On this episode, David Roberts pulls one stretch from each July conversation into a single hour, with two Minnesota utility regulators, a Spokane city council member, a Hawaii state senator, a co-founder of a battery materials company, and more.

Chapters:

Silicon anodes for batteries unlock greater energy density and faster charging times31 juil. 202600:45:50
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

Materials in lithium-ion battery cathodes have continuously evolved since the 1990s, but anodes have stubbornly remained graphite. Now, finally, there’s some innovation on that side: silicon anodes, which engineers have struggled to master for a decade, are finally coming into wide commercialization. They enable up to five times the energy density of graphite anodes, charge many times faster, and are poised to revolutionize the battery market. In this episode, I talk with Rick Costantino, co-founder and CTO of Group14, which is selling a silicon-carbon composite material for anodes. They’re already selling to dozens of large battery manufacturers and expect silicon anodes to completely take over the market by 2030.

Should we feel good about the trajectory of clean energy post-Trump? 29 juil. 202601:27:50
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 Inflation Reduction Act (IRA) established substantial tax credits for wind and solar power. Trump’s One Big Beautiful Bill Act (OBBBA) eliminated those tax credits. How much damage did that do to the overall trajectory of clean energy in the post-Trump world? A new research commentary argues that the damage was less than many had feared and that the road forward for clean energy is less about restoring those credits than about easing the permitting and interconnection constraints inhibiting renewable energy. Today I talk with author Lily Bermel about the modeling her commentary is based on and the somewhat controversial conclusions she draws from it.

The US is terrible at building public transit. Here's how to get better.22 juil. 202601:07:41

America once led the world in building transit and now leads the world in what transit costs, roughly three times the international average per mile, measured not against authoritarian megaprojects but against Italy, Spain, and Japan. On this episode of Volts, David Roberts talks with Will Poff-Webster of the Institute for Progress, who put together the new Transit Abundance Playbook, and Stephanie Pollack, former head of the Massachusetts Department of Transportation and former acting administrator of the Federal Highway Administration. Their argument is that the costs are a policy choice: federal funding rules teach transit agencies to plan on a napkin and do the real work years later, to hire the lowest bidder over the one they know will deliver, and to defer to anyone holding a veto, while highways operate under looser versions of the same rules. As Pollack puts it, "if you hate transit, you should spend less on it." A surface transportation reauthorization bill is coming, and two of the playbook's proposals have already reached the House version.

Making sense of the data center backlash20 juil. 202601:00:38
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

Data center opposition has gone from nonexistent to organized in about two years, roughly 120 moratoriums across 38 states, and it does not track proximity: Gallup finds 70% of Americans oppose a data center near them, while only 8% of opponents live near one. On this episode of Volts, David Roberts joins Energy Empire hosts Jigar Shah and Jamie Nolan, along with Arnab Pal of Deploy Action, for a crossover conversation, and his argument is that everyone is solving the wrong problem. The hyperscalers could buy their way to consent for a rounding error, batteries in basements, solar on roofs, funded schools, lower bills, and they refuse, which David reads as a symptom of low social trust that no amount of better modeling touches. “This is not a technocratic problem that you can just solve with a few switches,” he says. Thirty-six governors go to the ballot this fall having to answer for it.

Spreading the good news about electrification15 juil. 202601:03:05

Most of the energy decisions that touch daily life in America get made in state legislatures, and the people making them are increasingly new to the job. In smaller states, a freshly elected lawmaker gets a pad of paper, no staff, and about 150 lobbyists at the door, then votes on billion-dollar energy budgets in a landscape where the technology changes faster than anyone can track. On this episode of Volts, David Roberts talks with Hawaii state Senator Chris Lee, co-founder of the Electric Innovation Initiative, a bipartisan network betting that education moves electrification faster than mandates: put lawmakers in front of working technology, connect them across state lines, and let affordability carry the argument where climate framing will not. As Lee puts it, "nine times out of ten, people just don't know what they don't know."

Want less sprawl and more urban infill? Try a land value tax!10 juil. 202601:09:56
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

Property taxes are two taxes stapled together: one on the land, one on whatever gets built on it. Put up an apartment building and the bill goes up. Pave the lot for parking and it stays low. It discourages building and rewards land speculation. The answer? Tax the buildings less and the land more. The idea of a “land value tax” goes back 150 years, but implementing it today involves navigating tricky constitutional issues. In this episode, I talk with Greg Miller of the Center for Land economics about the rationale for such taxes, and with Kitty Klitzke, a Spokane, Washington council member, about the difficulties of putting it in practice in a real city.

Following a stunning clean energy victory over right-wing donors on an obscure Arizona utility board, organizers are setting their sights on a much bigger prize: the state’s powerful utility commission. I chat with Charlie Fisher and Ning Mosberger-Tang about how they used disciplined messaging to overcome massive opposition spending and historically abysmal voter turnout. We discuss whether this localized ground game can scale to a massive statewide electorate and help build a durable, nationwide clean energy political machine.

You might have noticed that it’s kind of hot out there. And it’s only going to get worse: global demand for cooling is projected to triple by 2050. Finding a way to cool spaces and people without frying the planet is a crucial climate challenge. I’m joined by RMI’s Ankit Kalanki to unpack the hidden world of AC refrigerants and testing standards, the crucial distinction between lowering temperatures and dehumidifying, new AC technologies on the horizon, and the building and urban design changes that can take some of the pressure off.

Why is the latest fossil fuel crisis pushing the world toward rapid electrification instead of a drilling boom? To find out, I chat with Tim Sahay and Kate Mackenzie, hosts of the Polycrisis newsletter and podcast, about the concept of “polycrisis” and the global rise of manufacturing-heavy electrostates. We examine the massive global diffusion of cheap electrotech and discuss why American climate wonks need to look past domestic policy and start paying attention to international macroeconomics.

In the US, clean energy tends to get bogged down in red tape, but there’s one category that you can install immediately, with no one’s permission, because it plugs right into your wall outlet. This week, I chat with James McGinniss of David Energy about plug-in DERs — specifically, small batteries that commercial tenants can install without permits or landlord sign-offs. We explore the economics behind these micro-projects, look at how they aggregate into virtual power plants, and break down why this hyper-local approach could eventually outcompete massive utility infrastructure.

Conventional punditry loves the narrative that woolly-headed progressive standards over-burdened federal climate spending and slowed everything to a crawl. In this episode, I talk with Betony Jones about her time designing labor policies at the DOE and what she learned from interviewing dozens of companies that received federal funding. We explore the difference between bad rules and weak administrative capacity, how the DOE successfully streamlined century-old Davis-Bacon compliance, and why creating high-quality jobs is essential for global competitiveness.

As affluent homeowners defect to heat pumps, the massive costs of maintaining America’s aging gas pipelines are being concentrated onto a shrinking base of customers who can afford it least. To understand how to prevent an impending utility death spiral, I talk with the Building Decarbonization Coalition’s Kristin George Bagdanov and Panama Bartholomy. We discuss the legal limits of a utility’s “obligation to serve,” the potential for gas companies to transition into geothermal thermal energy networks, and why the US has suddenly become the global leader in heat pump sales.

Are data centers and electrification going to break the US power grid, or are they the secret to making it cheaper for everyone? In this episode, I talk with Pier LaFarge of Sparkfund about Minnesota’s landmark decision to let Xcel Energy deploy batteries directly into local distribution networks. We look past the politics and map out how a battery-saturated system can socialize the benefits of load growth, ushering in an era of boringly reliable, low-cost energy by 2030.

Most people think that coordinating the behavior of thousands of distributed energy resources requires some kind of third-party middleman, like an aggregator managing a VPP. My guest today, veteran research scientist Bruce Nordman, believes there’s a better way: dynamic, time- and location-specific retail prices, communicated directly to consumer devices, which would cut out the middleman and leave more value with customers.

Why do climate funders prefer cutting checks for electric vehicles over fighting for dense, transit-oriented housing? I talk to Ben Holland, who recently interviewed major climate foundations about their anti-urbanism bias, and returning guest Caroline Spears, who is working to pass climate-friendly housing policy at the state level. We discuss why obsessing over easily quantifiable emissions reductions is blinding the movement to massive, tractable wins, and why ignoring zoning reform is no longer an option for serious climate advocates.

Using more of the grid we’ve already built01 avr. 202601:05:20

The US power grid runs at about 50% capacity on average — built for its worst day, underutilized every other day. As demand surges from data centers and electrification, utilities are racing to build more infrastructure. But Ian Magruder, who heads the new industry-backed Utilize Coalition, argues there's a cheaper, faster path: better use what we've already built — it will enable faster growth and bring down ratepayer bills, potentially by billions.
