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.

In this episode, I talk with GM Energy executive Aseem Kapur about General Motors’ move into bidirectional EV charging and home energy management. We dig into the practicalities of turning hundreds of thousands of EVs into mobile backup generators, how to navigate a patchwork of 4,000 different utilities, and what it takes to get everyday consumers to see their cars as grid assets.

The UK has just released its seventh carbon budget, recommitting to the aggressive climate targets suggested by its nonpartisan Climate Change Committee. Can the Labour government actually hit those targets while keeping energy prices for the British people under control, even amidst a newly hostile political landscape? In this episode, I talk with the UK’s new climate minister, Katie White, about those challenges and more.

The North American Electric Reliability Corporation has issued a historic warning about AI data centers. I chat with energy experts Colin McCormick and Doug Bryan about the unique electrical engineering challenges of giant computational loads that can abruptly drop hundreds of megawatts of power in the blink of an eye. We dive into the upcoming regulatory battle between hyperscalers and operators, the sudden rush for firm gas generation, and how software updates and battery storage could eventually make data centers a tool for grid stability instead of a liability.

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.
