quote: Regarding water, it's a non-issue. Even in expensive areas, it's $50 per thousand cubic feet of treated water. A thermoelectric plant will evaporate 0.5 gallons of water per kWh, so that works out to $0.003/kWh. The real figure will be much less for untreated water. Interestingly, the water evaporated from the reservoir behind hydroelectric dams is over 10x greater per kWh. Source: http://www.nrel.gov/docs/fy04osti/33905.pdf
