Pathways to Water-Smart Power
This chapter looks at some of the steps underway for reducing the large amounts of water used by thermoelectric generating plants to produce most of the world’s electricity. Thermoelectric plants use coal, natural gas or nuclear power to generate power. These plants require large amounts of freshwater for producing steam in the boiler, for cooling and condensing the steam after it has been used to power turbines to generate electricity, and for scrubbing flue gas to remove and collect potential air pollutants.
