Fridges and freezers are big power users - they can account for around 14 per cent of your household's annual power bills. But there are a few small adjustments that you can make that will help your fridge run more efficiently, and save you a few dollars too.
For example, fridges need to be set at 3-4°C(1) and freezers at -18°C to keep food fresh. Any lower and you're just paying for wasted power.
Lowering your fridge temperature by a tiny 1°C will quickly add up on your power bill, as well as generating about five per cent more carbon pollution each year.
