Understand Your Energy Usage

Understanding how your energy is used in your home is a key factor in determining the best ways to reduce your power bill.
Below is a breakdown of the energy usage for an average home in Australia1.
According to yourhome.gov.au, household appliances account for around 33% of energy consumption in an average Australian household, with heating and cooling systems accounting for approximately 40% of the total energy use.

There are several approaches you can take towards reducing your energy consumption, and a multi-faceted approach across several areas to maximise energy efficiency is recommended. Follow our tips below to assist you in lowering your energy consumption.

Heating and Cooling

By isolating rooms in your home which are heated or cooled you can reduce the energy requirements of your system. Switching your system off when you leave the house and installing quality ceiling insulation are also highly effective, while reducing the times you have the system running by wearing warmer clothes or not cooling below 23 degrees can also go a long way to keeping your costs down.


Many appliances can still use a considerable amount of energy while in standby mode. If you do not require the device operating, particularly during peak demand times, you are much better off switching appliances off at the wall. Your refrigerator is one of the most expensive devices in your home, so ensuring the seals are functional and having the temperature set between 3-5 degrees and freezers set to -15 can help reduce the energy load. It's important to consider the energy ratings of your appliances when purchasing, as better energy ratings will save you money in the long run. Washing your clothes in cold water and hanging them to dry outside rather than using the dryer will also save you dollars.

Hot Water

Minimising shower times can have significant impacts on your energy bill, as the more water that remains in an electric hot water system over the day, the less time the system is required to heat at night. Restricting yourself to 3-4 minute showers and installing a 3-star rated shower head could contribute to your home energy saving plan.


Outdated incandescent and halogen light globes use a considerable amount more energy than newer technology LED lights, as well as having a much shorter life span. Replace your old lights with energy efficient light globes and ensure you switch off lights when not in use. A small flick of the switch could help you save energy and money.
