10 Summer Energy Saving Tips to Lower Your Electricity Bill in Australia
Published February 12, 2026
As the Australian summer becomes warmer, it is common for the temperature in your home to be the most comfortable, thereby increasing the need for energy usage. However, it is possible to achieve the desired comfort while at the same time lowering the energy usage. The tips provided in the article are simple, practical, and suitable for use by many households.
1. Optimise Your Air Conditioner Settings
Keep the room cool by setting the air conditioner between 23°C and 26°C. Also, make sure the doors are closed if you want the cool air to stay inside the room you are using. Lastly, do not forget to turn off the air conditioner before leaving home.
2. Maximise Natural Ventilation
You can make the most of the cold mornings and evenings by switching off your air conditioning and opening your windows. This is a completely natural way of keeping things at a cool temperature, so it is certainly worth considering.
3. Use the Economy Setting
Most modern air conditioners have, as a feature, an economy mode or eco mode. Using this mode reduces electricity consumption by regulating how active the compressor is while keeping your space cool.
4. Harness Solar Energy to Maximum Potential
If you have solar panels, it would be a good idea to schedule the most energy-intensive activities, such as cooling your home or operating appliances, during the day. This way, you can maximize your use of solar energy. Another approach to reducing the need for energy later in the evening is afternoon precooling of your home.
5. Seal Draughts for Better Insulation
Gaps around the bottom of doors and the periphery of openable windows can allow warm air to infiltrate your home and put pressure on the cooling system to work harder. Putting in draught seals or weather strips is an uncomplicated, pretty inexpensive thing to do that would also reduce energy consumption by further improving the insulation.
6. Adjust Your Fridge and Freezer Settings
Set your refrigerator at 3°C–5°C and your freezer at -15°C to conserve energy. If you have a second refrigerator that is not in use, then switch it off as it will be wasting energy.
7. Consider Reverse-Cycle Air Conditioning
One of the most energy-efficient air conditioning systems is the reverse cycle air conditioning system, which can both cool and heat. It is recommended to clean the air filters to ensure their effectiveness.
8. Upgrade to Energy-Efficient Lighting
Replace old light bulbs with newer ones, for example, LED bulbs, which are more efficient and last longer. Remember to turn off lights in rooms you don’t use to help reduce consumption.
9. Try turning off the Appliances
Although the appliances are turned off with the help of unplugging, they still need some power. Try switching off the device or make use of the power board to turn off all the devices.
10. Maintain Your Cooling Systems
To keep your air conditioner running efficiently, clean or change filters frequently. You might want to get a professional to service it to make sure it works optimally by using as little energy as possible.To keep your air conditioner running efficiently, clean or change filters frequently.

Cut in your energy consumption this summer are beneficial to the environment. But apart from that, such reductions would also help alleviate the load from the electrical grid, especially during peak demand. Small changes like sealing draughts or using your air conditioner’s eco mode can make a big difference in cutting your energy consumption.
