This oil shock won't be like the others
This is a free preview of a paid episode. To hear more, visit www.volts.wtfWhy 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.

Are plug-in DERs going to spark a grid revolution?
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/subscribeIn 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.

Giving clean electricity a political voice of its own
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/subscribeWhy is clean electrification, the most exciting, dynamic, hopeful sector of the US economy, still such a 98-pound weakling in DC backroom fights? In this episode, I talk with investor and entrepreneur Steve McBee about Amped, his new effort to boost the industry’s political influence and give it a little swagger — by telling a more compelling story, getting better information to lawmakers, and pulling hundreds of billions of dollars in stranded capital off the sidelines.

A limited defense of Biden's everything-bagel industrial policy
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/subscribeConventional 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.

How to phase out residential gas equitably
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/subscribeAs 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.

Sooner than you think, electricity is going to be cheap, abundant, and boring
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/subscribeAre 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.

Telling the story of the grid
This is a free preview of a paid episode. To hear more, visit www.volts.wtfBen Eidelson and Anay Shah run the Stepchange podcast, which recently put out a magisterial four-hour (!) episode on the history of the US electricity grid. I talk with them about some of the colorful characters and stories involved, the big fights and broad lessons learned, and how the history echoes in today’s political and technological struggles.

Electrifying industrial steam with heat pumps
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/subscribeBoiling water to make steam for industrial processes consumes an enormous amount energy around the globe, yet it has proven remarkably resistant to electrification. In this episode, I talk with Addison Stark of AtmosZero about why replacing the standard fossil-gas boiler requires an entirely new approach to industrial heat pumps. We discuss the engineering behind his high-temperature system, the challenges of scaling up, and the growing imperative to get free of global LNG markets.
