Energy Storage, Less Widespread Renewables Provide Four Percent of U.S. Capacity
The U.S. Energy Information Administration has estimated energy storage and renewable fuels other than hydro, wind and solar together provide four percent of electric capacity in the United States.
As of the end of last year, 195 utility-scale geothermal units were in operation, totaling 3.7 GW. The largest cluster of these are the Geysers complex in Northern California, which has a capacity of 943 MW.
Wood and wood waste biomass makes up the largest share of biomass at 10.2 GW of capacity. Municipal solid waste, landfill gas and other waste biomass have capacities of 2.2 GW, 2.12 GW and 0.8 GW respectively.
California leads the nation in hydroelectric pumped storage, geothermal, landfill gas and battery capacity, while Florida leads in municipal solid waste. Virginia’s Bath County is the site of a 3 GW hydreoelectric pumped storage plant, which is the largest in the nation.
