Will every building in your city one day be powered by a battery? Are batteries the key to our cities' energy future? In this episode, Molly and Jim look at how energy storage could change everything about how we turn on the lights and get around town. And they'll explore how renewable energy might keep our cities running even when the sun doesn't shine and the wind doesn't blow. They talk with John Zahurancik of Fluence Energy and Rushad Nanavatty of Rocky Mountain Institute. They also make an inspiring phone call to Dan Neil, auto columnist for the Wall Street Journal.
