For a variety of reasons, the single biggest energy conservation move that you can make is to put a cover on the pool or spa.

A solar blanket goes one step farther, collecting heat from the sun, which lessens that reliance on fossil-fuel burning heaters. In addition, the cover will save on the amount of chemicals and water that need to be added.  Our 12-mil blankets are loaded with thermal bubbles that retain heat at night and even on cool cloudy days and they are available in blue and clear.
