Control Measures

Instead of discharging heated water into lakes and streams, power plants and factories can pass the heated water through cooling towers or cooling ponds, where evaporation cools the water before it is discharged.

Alternatively, power plants can be designed or refitted to be more efficient and to produce less waste heat in the first place.

Cogeneration - process through which, the excess heat energy from generating electricity can be used in another manufacturing process that needs such energy. Where homes or other buildings are located near industrial plants, waste hot water can be used for heating—an arrangement often found in Scandinavian towns and cities, and proposed for use in China.

To prevent thermal pollution due to devegetation, the prescription is simple: do not devegetate and leave strips of trees and vegetation along streams and shorelines.

All efforts to control erosion also have the effect of keeping water clearer and, thus, cooler.
