What if there was a way to continue using fossil fuels for energy without emitting CO2 into the atmosphere? To prepare for a new listener question about carbon capture, we're re-airing this season two episode.

Is hydrogen fuel a climate solution? That depends on how you produce it.

Just 20 years ago, hydrogen cars and battery electric cars were pretty evenly matched as clean alternatives to gas-powered vehicles. But today, batteries are way ahead: the big car companies are rapidly electrifying their lineups, while only a few hydrogen cars are available. What happened?

Hydrogen gas acts like a fossil fuel, but with no carbon emissions. Is it the silver bullet we’ve been waiting for? To prepare for some new listener questions about hydrogen energy, we're re-airing this season four episode in which Prof. Svetlana Ikonnikova of the Technical University of Munich explains how hydrogen works and its potential in the energy transition.

MIT Professor Michael Howland returns to the podcast to answer a listener's question about the risks of wind energy to birds—and explain how wind turbines compare to coal plants, power lines, office towers, housecats, and other threats to birdlife in the modern world.

You might have heard how wind turbines failed in Texas during a terrible cold front in 2021. Does this mean we can’t rely on this clean, renewable source of energy when the weather turns extreme?
