Editing Distributed generation (section)

==== Flywheels ====

: An advanced [[flywheel energy storage]] (FES) stores the electricity generated from distributed resources in the form of angular [[kinetic energy]] by accelerating a rotor ([[flywheel]]) to a very high speed of about 20,000 to over 50,000 rpm in a vacuum enclosure. Flywheels can respond quickly as they store and feed back electricity into the grid in a matter of seconds.<ref name="ScienceNews">{{Cite journal
