When excess electricity is present in a system, it can be used to pump water up to a reservoir. Then, when that power is needed, the water is sent through a turbine to generate electricity. <a href="http://www.wired.com/wiredscience/2010/03/compressed-air-plants/" rel="nofollow">The U.S. electric system has 2.5 gigawatts of pumped hydro storage capacity</a>, but most of the good, cheap sites are already occupied, and creating new reservoirs is not environmentally benign." “The nation’s largest energy storage option right now is pumped hydroelectricity.
