energy storage
Saving electricity later
Energy storage is the capture of energy for later use.
Batteries store electrical energy chemically.
Reservoirs store potential energy by holding water at elevation.
Flywheels store kinetic energy through rotation.
The term appears frequently in discussions of renewable power, where storing energy from intermittent sources like wind and solar is a central challenge: Grid-scale energy storage remains expensive.
