One thing that helped my electricity bill was changing over my old hot water service to a heat pump system..
These Chromagen systems are not cheap, but it my State they are free!!..Provided for by the State Government..
If you live in SA..definitely worth looking into..Other States may have a similar deal..
Wow, that sounds like a fantastic deal for South Australians @Prof. Many thanks for sharing.
