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?

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?

People all around the world write into our team with questions about climate change. So this season, we’re working with scientists and experts at MIT and beyond, to answer those questions in language we can all understand.

The United States has a goal to power the country with 100% clean electricity by 2035. Unfortunately, our energy regulations are not set up to make this much change this quickly. Energy economist John Parsons of MIT joins the show to explain how much clean energy infrastructure we need to build, the obstacles to building it, and reform ideas to transform our energy system on the timeline our climate goals demand.
