• Buy the smallest refrigerator model that meets your needs. Generally, larger models consume more energy.
  • Consider the necessity for additional features such as automatic icemakers and through-the-door dispensers, as they increase energy use.
  • Choose a refrigerator model by using the tick rating system on the energy label. A 1-tick refrigerator may cost you about $75 more a year* in electricity bills compared to a 3-tick model. The more ticks, the more energy efficient the model is.
  • Allow some space around the refrigerator (e.g. 5cm or as recommended by the manufacturer) to improve air circulation to cool the compressor and condensing coils naturally.

*Based on electricity tariff of $0.27 per kWh, assuming a 400-litre refrigerator.

  • Adjust the thermostat in the refrigerator to the recommended setting. Overcooling your refrigerator wastes electricity.
  • Allow hot food to cool before storing it in the refrigerator.
  • Do not overload the refrigerator to ensure that cold air can circulate freely. Too many food items may reduce air circulation and thus the cooling rate. Consider using food storage containers to minimise clutter.
  • Cover liquids and wrap food items that are stored in the refrigerator. Uncovered liquids and food items releases moisture. As internal moisture levels rise, the compressor is required to work harder, resulting in unnecessary energy wastage.
  • Do not leave refrigerator door open. Decide what you want before opening the refrigerator door and closing it.
  • Make sure that the refrigerator door shuts tightly. Test this by closing the door over a piece of paper so it is half in and half out of the refrigerator. If you can pull the paper out easily, the hinge may need adjustment or the seal may need replacing.
  • Switch off the refrigerator when it is being cleaned to save electricity.
Other Green Tips
  • Allocate one area of the fridge for leftover food and do a quick inventory of the fridge 2 to 3 times a week to ensure that food is not pushed to the back and left to spoil.
Fun Facts
  • While energy efficient models may have higher purchase prices than less efficient ones, they tend to have lower life cycle costs due to their lower electricity consumption over their lifespan.
