Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding. .
A typical system consists of a flywheel supported by connected to a . The flywheel and. .

Grid energy storage is a collection of methods used for energy storage on a large scale within an electrical power grid. .
Energy storage is the capture of produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an .
MillsThe classic application before the was the control of waterways to drive. .
Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in or and their multiples, it may be given in number of hours of electricity production at power plant .
In the 20th century grid, electrical power was largely generated by burning fossil fuel. When less power was required, less fuel was burned. , a mechanical energy. .
OutlineThe following list includes a variety of types of energy storage:• Fossil fuel storage• .
The (IESDB), is a free-access database of energy storage. .
The economics of energy storage strictly depends on the reserve service requested, and several uncertainty factors affect the profitability of energy.
