According to the U.S. Geological Survey, electric generation accounts for 3.3 percent of freshwater consumption, about the same percentage as the industrial sector (3.4 percent) and raising livestock (3.2 percent). The residential sector consumes 6.7 percent of freshwater, while the commercial and mining sectors consume the least, at 1.3 percent and 0.8 percent, respectively. The largest consumption of freshwater is for irrigation, at 81.3 percent.
To put residential and electric power water consumption in perspective, a typical nuclear power plant supplies 740,000 homes with all of the electricity they use while consuming 13 gallons of water per day per household in a once-through cooling system and 23 gallons per day per household in a wet cooling tower system. By comparison, the average U.S. household of three people consumes about 94 gallons of water per day.
