The choice of cooling system used in a coal plant affects not only its water requirements but also the efficiency of the power plant as a whole. According to estimates by the US Environmental Protection Agency (EPA), coal plants that use dry cooling produce about seven percent less power than those that use wet-recirculating systems.
