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 energy to the system correspondingly results in an increase in the speed of th. Main componentsA typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce fricti. .
Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles. .
In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have. [pdf]

Distribution grids are vulnerable to outages that can affect large regions and millions of people and businesses, particularly as a consequence of extreme, destructive weather events. When parts of the grid are equipped with DER, they can continue serving other loads on the same distribution network, meeting. .
Solar DER can be built at different scales—even one small solar panel can provide energy. In fact, about one-third(link is external)of solar energy in the United. .
Another way DER and microgrids can contribute to grid stability is by aiding “black start” processes, which turn power on after it has gone down. During a. According to the Office of Energy Efficiency and Renewable Energy, DERs “are small, modular, energy generation and storage technologies that provide electric capacity or energy”—sources such as solar panels on roofs, batteries, electric vehicles, heat pumps, small wind turbines, and even smart thermostats.
