Keep it cold, but not icy

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.

• check temperature with an appliance thermometer
• set the thermostat or fridge temperature to suit both load and contents
• keep items at least 50mm away from the coils at the back of the fridge⁽²⁾
• install your fridge or freezer in a cool spot out of the sun and away from the oven
• keep door seals clean and check the door closes properly
• don't open the door too often or leave it open long – warm air will get in
• turn off, empty and clean or use the holiday mode if you're going away
• defrost regularly or when ice is more than five millimeters thick
• do not overload, leave room inside for cool air to circulate

Setting your fridge temperature at the right level and making sure that it is operating efficiently can shave about $30 off your power bill and lower your household carbon pollution by 100kg (or 2,000 black balloons) a year. Just imagine the huge environmental savings if everyone in your street did the same thing!
