  1. Purchase the most energy efficient electronic devices, check energy label of the machines and buy Energy Star certified electronics. Generally the most modern appliances are more energy efficient. You can compare products at energyrating.gov.au website.
  2. Prefer laptop when buying computer because it uses much less energy than desktop.
  3. If you are not using your computer or laptop then shut it down.
  4. Use passive cooling in your computer whenever it is possible.
  5. Use power management settings on your computer and if you don’t use your computer’s full computational capacity, and set the power management settings to low.
  6. Use standby mode and screen saver of your computer if you do not use it for more than some minutes. Standby power is a key source of hidden energy costs that could amount to 10 per cent of your electricity bill, so when not in use turn appliances off at the wall.
  7. In case of televisions and monitors replace your old CRT models to flat screens. Flat televisions save money and save energy on electronicsconsume much less electricity than of older models.
  8. Switching off appliances that are on standby and turning off anything that doesn’t need to be on.
  9. Switch to green power that you can purchase on behalf of your electricity supplier. Green power is government accredited clean energy originated from renewable energy sources like wind, sun, water and waste. Accredited green power reduces greenhouse gas emissions and is purchased on behalf of your electricity supplier.
  10. Unplug or turn off the power switches during the night while you are sleeping – excepting that one which is used at your refrigerator and fridge.
  11. Unplug mobile phone chargers when not in use.
  12. When washing your clothes, wash at 30° or 40°. Nearly 85% of energy used for laundry comes from heating the water. It is enough to wash average and not too dirty clothes at 30°. Wash only full loads of laundry.
  13. Electrical retailers sell new fridges, freezers and fridge freezers with an energy efficiency rating label (A-G). Choose an A++ or A+ rated appliance to get the most energy efficient. Do not place fridges and freezers close to cookers.
  14. Don’t keep your refrigerator or freezer too cold. To check temperature is at the recommended level you can use a fridge thermometer. Regularly defrost refrigerators and freezers. If these tend to frost up quickly, than check the door seal.
  15. Do not leave doors or lids open longer than necessary and make sure your refrigerator door seals are airtight. Keep the cold air in and do not let it escape. If you can’t trap a piece of paper in the door, the seal probably needs replacing.
  16. Keep the back of your fridge/freezer dust free because it helps to improve energy efficiency.
  17. Never overfill a fridge to ensure the cold air can circulate freely. Between your refrigerator and the walls leave enough space in order to air can easily circulate around the refrigerator.


When you save energy on electronics and your electronic devices, you can also reduce your carbon footprint at the same time.
