Solar energy is made during the day, but energy demand is highest when the sun sets. In order for intermittent energy sources, like wind and solar, to help in these peak periods, we need a way to store energy.

In this episode, we look at energy storage, understanding how we will store energy for a renewable energy future and what ducks have to do with it. We speak to battery researcher Eric Kazayk about how battery storage fits into this picture, from grid scale storage to electric vehicles.
