Start by checking the Australian Energy Rating Label, which shows an appliance’s star rating and estimated annual energy use. Compare similar models using the kilowatt-hour figure, not just the number of stars, and consider the appliance’s size because a larger model may use more electricity. Features such as heat-pump technology, efficient wash cycles and good insulation can reduce running costs. Turn appliances off at the wall when practical to avoid standby use, and check the manufacturer’s specifications or speak with an energy retailer if you need help estimating costs.
