Use ceiling fans

Are you making the best use of your ceiling fans? Compared to other available cooling options ceiling fans are one of the cheapest ways you can keep cool in summer so try to use them instead of air conditioners when you can.

A ceiling fan on high uses around 70 watts. That costs about 1.2c for each hour you run it and if you have the fan running at a lower speed then it will cost even less.

An average split system air conditioner on cooling cycle uses around 1000W (or more!), that costs about 18c for each hour you run; it may not seem like much but if you have more than one split system running and they are being used to cool the house for extended periods of time it all adds up. Compared to running costs for a ceiling fan that's 15 times more expensive!
