Nuclear Power uses more Water than Coal for the same energy produced. A 2009 World Economic Forum paper provides the following figures: "A megawatt-hour (MWh) of electricity from coal uses 20 to 270 litres of water at the coal mining stage and an additional 1,200 to 2,000 litres when the energy in the coal is converted to electricity, totalling 1,220 to 2,270 litres of water consumed per MWh. In comparison, nuclear energy uses 170 to 570 litres of water per MWh during the mining of uranium and production of the reactor fuel and an additional 2,700 litres per MWh as the energy from nuclear fission is converted to electricity, for a total of 2,870 to 3,270 litres of water consumed per MWh."
