Skeptics of the green energy movement have always asked: What do you do when there’s no sun for the solar panels and no breeze to stir the blades of the windmill, but you still need power? Batteries can store excess energy created when the conditions are favorable to be used for precisely those times —

In a scene from the PBS docuseries “NOVA: Chasing Carbon Zero,” Chef Chris Galarza removes an ice cold frying pan from a freezer and places it on an induction burner.

Soft-spoken Ray Daly, the founding owner of Ray’s Reusables, is on a zero-waste mission. But her approach is more supportive sherpa than zealous missionary.
