Energy storage, less common renewable resources make up 4 percent of US power capacity

Hydroelectric pumped storage, batteries, flywheels, and renewable fuels other than hydro, wind, and solar accounted for four percent of the electricity generating capacity in the United States in 2016, according to the U.S. Energy Information Administration (EIA). Hydroelectric pumped storage plants tend to be the oldest facilities among this group. At the end of 2016, there were 23 gigawatts (GW) of capacity in operation, 88 percent of which was in operation before 1990. The largest hydroelectric pumped storage plant in the United States, at slightly over 3 GW, is located in Virginia’s Bath County.
