Many newer power plants have cooling systems that reuse

Recirculating systems can consist of a cooling tower or a cooling pond with both using ambient air to draw energy out of the cooling water that was used to condense the steam. At a cooling tower, the process of lowering the cooling water temperature produces the plumes of evaporation often associated with power plants.
