As We Generate More Electricity From Sun and Wind, Where Do We Store It?

The big thing holding us back from wholesale use of renewable energy is a reliable long-term storage mechanism. But scientists are working hard to develop a battery that can make the most of solar- and wind-generated energy. This ClimateWire article describes a few of the promising technologies under consideration for storing electricity collected by solar panels and wind turbines for use at any time. Aluminum air batteries, anyone?
