Compare the Australian Energy Rating label when buying appliances, checking both the star rating and estimated annual electricity use, as a larger appliance may use more energy despite having more stars. Choose the right size for your household and use eco settings, full loads and cold-water cycles where suitable. Clean filters, avoid unnecessary clothes-dryer use and switch appliances off at the wall to reduce standby consumption. When replacing major equipment, a qualified installer can explain efficient options such as heat-pump hot-water systems, while your retailer can help you understand how usage times affect your plan.
