Comprehensive environmental management programs will yield optimal protection when used in choosing electric generation facilities and cooling systems.When considering water resources as part of this holistic approach, power generation accounts for 3.3 percent of freshwater consumption.Among cooling technologies for coal, natural gas and nuclear power plants, “once-through” systems actually consume only 1 percent of the water they withdraw. Wet cooling tower systems at these facilities, on average, consume twice as much water as once-through systems.Power plant cooling systems do not have an adverse impact on aquatic life, according to scientific studies.Compared to other energy sources used for electricity production, nuclear power plants use moderate amounts of water and minimal land per amount of electricity produced.
