This episode of “Climate Sense” is about electricity—the stuff that comes out of the outlet in your wall. Electricity is the future, but many of us don’t think about it beyond the wall plug. In this episode, Samantha Gross explains that electricity is central to transforming our energy system. The costs of wind and solar electricity have plummeted in recent years, making them no longer cool and expensive, but now cool and cheap, in many cases cheaper than the fossil fuel electricity they replace. And electricity is a clean, quiet, and very efficient method for using energy in everything from homes to transportation to industry.
