There is no doubt that swimming pools are big energy consumers. North American pool owners / operators spend billions of dollars annually to heat the nation's pools. Much of this energy is often wasted and can be saved with proper management.
Covering your pool when it's not in use is the single most effective way of reducing energy loss. Other ways include minimal use of water features and a reduction in the disturbance caused by misdirected jets.
The use of water features or excessive turbulence on the water surface from misdirected return jets greatly increases evaporation, and thus energy loss.
