Look for appliances with a high star rating on Australia’s Energy Rating Label, but also compare their annual energy-use figure because larger models can use more electricity. Choose a size that suits your household, and consider the purchase price alongside expected running costs over the appliance’s life. Features such as efficient wash cycles, heat-pump technology and good insulation may reduce energy use, depending on the product. Check the official energy rating calculator and ask the retailer for current product information before buying.
