Put your kitchen on an energy diet

There are a few ways that you can save when it comes to the kitchen but the biggest energy consumer is your fridge so it’s important to get the right one. On average, 13% of Victorian household energy costs are spent on running refrigeration. Most households have at least one, and they run for 24 hours a day, 7 days a week, that’s a lot of energy! 

If you think you have a power-hungry fridge, consider replacing it with an energy efficient one – it will save you money in the long run and be great for the environment too.

How to boost the energy efficiency of your Fridge and Freezer

  • When shopping for a fridge, go for one with at least a 2.5 star energy efficiency rating. Visit the Energy Rating website to search and compare the energy efficiency of different fridges.
  • If you’re after a chest freezer, look for ones with a 3 star energy efficiency rating, every extra star will reduce your running costs by around 20%
  • Look for a fridge with an alarm: yes its annoying, but at least it will make you shut the door!
  • Make sure fridges and freezers are located in a cool, well-ventilated space with a gap of at least 5 cm for ventilation and heat dispersion.
  • Set the temperature of the fresh food compartment to 3 to 5 degrees Celsius. The magic number for your freezer compartment is -15 to – 18 degrees Celsius.
  • Avoid overcrowding your fridge, this can interfere with the circulation of cold air and possibly cause the doors to not shut properly.
  • Keep any coils at the back of the fridge or freezer free of as the dust will act as a warm fussy insulator making your fridge work harder than it needs to.
  • Defrost your freezer 2 or 3 times a year to keep it running efficiently.


Dishwashers are star-rated for both energy and water efficiency. With every extra star, you could save 30% on running costs, so look for models that have the most stars are use the least water.

  • If your dishwasher has an energy-saving cycle, try to use it whenever possible and try not to pre-rinse dishes before putting them in the dishwasher.
  • If your dishes aren’t coming out clean, it could mean your dishwasher needs a service or is over stacked.
  • Always wait to wash a full load, because most dishwashers use the same amount of water whether it’s completely full or not.

Other useful tips in the kitchen

  • To minimise the amount of cooking time, cut your food into smaller portions and use a lid. It will save energy and you’ll have dinner on the table quicker!
  • Take your meals out of the freezer the night before so you don’t need to use the microwave to defrost them.
  • Use a pan or pot that is of suitable size for the burner, using a small pot on a large burner can waste a lot of unwanted energy.
  • When you are using the oven, keep the door closed. Every time you open it not only are you letting the heat out, you are wasting energy and making the cooking time longer.
