Compare appliances using the Australian Energy Rating Label, looking at both the star rating and the estimated annual energy use in kilowatt-hours. A higher star rating can indicate better efficiency, but a larger appliance may still use more electricity than a smaller model, so compare similar sizes and features. Check the purchase price against likely running costs, and look for features such as efficient wash cycles and low standby power use. Your actual costs will depend on usage and electricity rates, so check the manufacturer’s specifications and your retailer’s tariff.
