Water for Power Plant Cooling | Union of Concerned Scientists

In the western US, wetrecirculating systems are predominant. Drycooling systems use air instead of water to cool the steam exiting a turbine. Drycooled systems use no water and can decrease total power plant water consumption by more than 90 percent. [2] The tradeoffs to these water savings are higher costs and lower efficiencies.
