Speak to your energy retailer and consider these energy saving tips

• Ask your retailer to undertake an energy audit of your home, this can usually be done over the phone, and can help to identify ways to save energy.
• Hot water, heating and air-conditioning can be a large part of your energy bill. Set your hot water thermostat to 60ºC. In summer, set your air-conditioning to between 23ºC and 26ºC and in winter your heating to between 18ºC and 21ºC. Remember to turn your heating and cooling off overnight.
• Close your curtains at night.
• Turn off lights when you leave a room.
• Don’t leave appliances on standby – turn them off at the switch.

In addition to making your home more energy efficient, you might also consider renewable energy investment in Australia, such as installing solar panels or joining a green energy plan
