Reduce the pool pump running time
Pool pumps can be the biggest power user in the home as the pump runs all year round.
In winter when the weather is much cooler and pool usage drops swimming pools generally need less filtering to keep them clear. Each hour per day you reduce the running time of the pump will save you around $50 per year (depending on what capacity pump you have)
Alice Solar City recommends you talk to your local pool shop for further advice.
