Freshwater is used to produce power at

About 77 percent of the freshwater used in the United States in 2005 came from surface-water sources. The other 23 percent came from groundwater. For 2005, most of the fresh surface-water withdrawals, 41 percent, was used in the thermoelectric-power industry to cool electricity-generating equipment.The United States produces a lot of electrical power, and water is important in that production. In 1995, there were about 2,690,000 billion watthours (gigawatt hours) of power produced by thermoelectric power plants (those plants that burn oil, gas, and coal, use geothermal energy, or use nuclear energy).

I hope this helps, Have a great day.
