Water use requirements for solar power plants depend on the technology and climate conditions at the site. In general, all solar power technologies use a modest amount of water (approximately 20 gallons per megawatt hour, or gal/MWh ) for cleaning solar collection and reflection surfaces like mirrors, heliostats, and photovoltaic (PV) panels.
Solar power plants, whether concentrating solar power (CSP) or photovoltaic systems (PV), offer pollution-free electricity generation with impacts on local water sources that are comparable to and often less than traditional fossil fuel generation.
First, solar isn't the most water-efficient form of energy generation, according to those 2012 figures. Wind handily beats out even solar PV at less than a gallon per megawatt hour. And second, the most widely used and generally reliable form of renewable energy we use is absolutely the worst in terms of water wastage.
Coal-fired power plants use up 1,100 gallons of water for each megawatt-hour of power produced. (A megawatt-hour is about what a typical California household would consume in six or seven weeks.) Nuclear and natural-gas-fired power plants use water 800 and 300 gallons for the same amount of power, respectively.
