Technologies like solar panels and batteries help us slow down climate change, but they’re not inherently perfect. In this episode of TILclimate (Today I Learned Climate), Suzanne Greene of the MIT Center for Transportation and Logistics and the MIT Environmental Solutions Initiative sits down with host Laur Hesse Fisher to help us navigate how to massively scale up clean tech while making a conscious and dedicated effort to ensure people’s rights, health, and safety.

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?

Why are EVs more popular than hydrogen cars?

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.

Do wind turbines kill birds?

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?

Do wind turbines freeze up in the cold?

Plants take in CO2 from the air to grow—and today’s atmosphere has about 50% more CO2 than it did before we started burning massive amounts of fossil fuels. So, is that great news for plants?
