The U.S. electricity system is undergoing the biggest change in its 130-year history. The scale of electricity generation is rapidly shrinking, from coal and nuclear power plants that can power a million homes to solar and wind power plants that power a few to a few hundred nearby homes. Electricity demand has leveled off, so that every unit of new wind and solar power produced for the grid displaces a unit of fossil fuel energy. Batteries and electric vehicles provide new tools for distributed energy storage.
