Mills Require Water For Coal

A simple model to help understand water use at power plants

These plants require large quantities of water, primarily for cooling [2] [3], andreport from the US Department of Energy [7] identified a total of 347 coal-fired power plants (from an analysis set of 580 plants) as vulnerable to water demand and/or water supply concerns.
