This week, we're pleased to hand the microphone over to our colleague: Dr. Melissa Lott. 

Melissa is the director of research here at the Columbia Center on Global Energy Policy. And for the last few months, she and her team have been working on a new podcast, called The Big Switch.

It’s a five-part series about how to clean up the energy system -- told in a clear, understandable and fun way. 

We are offering you the first episode of The Big Switch, right now. So I hope you’ll give it a listen and subscribe to the podcast on Apple, Spotify, and any other place you get podcasts.
