Building wind and solar farms is an important part of building a new green grid, but a calm night stops their energy generation cold. It’s just as important to research and build green energy storage — and to that at scale requires federal intervention as soon as possible, suggests a new report from MIT.

“The Future of Energy Storage” is part of a series looking at the transition of power sources in America, and this one is particularly relevant given the momentum currently enjoyed by the solar and wind industries. Too much renewable energy sounds like a good problem to have, but if it can’t be relied on as a city or region’s main or only source of electricity, they’re going to feel the need to hedge their bets with a coal plant or something like it.
