Water is fundamental to burning coal for power as it is heated into steam and used to turn the turbines that generate electricity. Water is withdrawn to support the electricity production cycle and consumed through evaporation. How much is withdrawn (overall) and how much is consumed depends on the cooling technology in a coal-based power plant.
