Environmental concerns: water use issues & cooling methods

There are many ways to cool a power station. The three main approaches are:

  • Direct - where water is pumped through the station and discharged back to the environment.
  • Evaporative - where large parabolic cooling towers are used and the water recirculated. Some make-up water must be added to allow for evaporative losses and limit concentrations of salts.
  • Dry - where water is recirculated with negligible loss, rather like a car radiator.
