Energy storage is changing the way electricity grids operate. Under traditional electricity systems, energy must be used as it is made, requiring generators to manage their output in real-time to match demand. Energy storage is changing that dynamic, allowing electricity to be saved until it is needed most. Learn more about the future of energy ...
