Power Moves: The Huge, Weird Batteries of the Future

Burning fossil fuels churned out by Big Oil can power the world 24 hours a day, 365 days a year, sending electricity almost anywhere near-instantaneously. Unfortunately, this very effective (and profitable) source of power is pushing ecosystems, animal species and human civilization closer to catastrophe every day.

Renewable sources such as wind and solar tend not to have these unfortunate side effects. But they aren’t nearly as dependable: breezy sunny days are generally not under our control. With nuclear power in retreat in most countries, these two sources of energy are the center of any hope humanity has to slow global warming. For that to happen, there has to be a way to save some of that power for, well, a rainy day.
