We need safe and efficient ways to store renewably generated energy to use when the wind stops blowing, when clouds form in the sky, and when demand for electricity jumps higher than normal. . Wind and solar energy are now cheaper than power generated from fossil fuels, but they require specific weather conditions. Batteries are at the core of the recent growth in energy storage and battery prices are dropping. .
