How Many Batteries Will It Take?

To survive the climate crisis, we need to electrify everything: our cars, of course, but also our appliances, homes, mass transit, entire neighborhoods and cities. Everything. 

That’s no small task. So to better understand why electrifying everything matters, and how we’re going to do it, we look at the aftermath of a natural disaster and talk to one man who used batteries to save lives. Then we spend a little time with an entrepreneur whose vision for an electric future includes turning every building into a Tesla (sort of). And we talk to U.S. Energy Secretary Jennifer Granholm on how we can seize this moment.
