Fridge and freezer.

  • Fridges can account for 7% of your household's total energy use^.
  • Avoid setting the temperature of your fridge or freezer too low.
  • Figure out what you need from the fridge before you open the door and let 30% of the cool air out.
  • A fridge operates most efficiently when it's at least three quarters full, so keep yours full but not overcrowded. Use water containers or bags of ice to fill empty space.
  • A freezer uses more electricity when there’s ice build-up, so defrost it regularly to help save energy. If ice builds up again quickly, check your door seals.
  • Keep the condenser coils at the bottom or back of your fridge clear of dust so air can circulate freely. It can otherwise make the motor work harder and use more power.
  • Regularly clean and check the seals on your fridge door to make sure they're tight. If you can close the door on a $5 note and remove it without any friction, you might need to replace the seals.
  • Always look at the Energy Rating label when you purchase a new fridge or freezer. The more stars, the less electricity it’ll use.

  • Unless you have a small electric hot water unit, run your dishwasher on hot water so it doesn’t use extra electricity to heat the cold water itself.
  • Wait until the dishwasher is fully loaded before you switch it on.
  • Use the economy cycle on your dishwasher with the lowest temperature and the shortest time when you can.
  • Avoid running your dishwasher during the hottest parts of the day so your air conditioner won’t have to work as hard to reduce the added heat and humidity.
  • Always look at the Energy Rating label when you purchase a new dishwasher. The more stars, the less electricity it’ll use.


  • Use a microwave instead of a traditional electric oven whenever you can and use less energy.
  • Stir or turn food regularly to reduce cooking time.
  • Always look at the Energy Rating label when you purchase a new microwave. The more stars, the more you could save on your electricity usage.


  • Limit how many times you open your oven door and stop heat from escaping.
  • Let frozen food defrost in the fridge overnight to avoid using the microwave.
  • Make sure frozen food is completely thawed out to save cooking time and energy.
  • Use a lid when you’re boiling water in a pot to save energy and cook food faster.
  • Don't preheat the oven for longer than you need to.
  • Slow-cooked dishes don’t need a preheated oven, plus you can turn the oven off 15 minutes before you take them out.
  • To get the most out of your oven or range-hood, use it to capacity by cooking everything at the same time if you can.
  • Use flat bottom pans with tight-fitting lids that match the size of your cooker’s burners to cut down on heat  loss.
  • Try to cook on your BBQ or in your microwave during summer to keep your kitchen cool.
