Energy-efficient appliances use less electricity to provide the same service as comparable models, which can reduce household running costs and emissions. In Australia, compare the Energy Rating Label’s star rating and estimated annual energy use, but also consider the appliance’s size, purchase price and how often you will use it. A larger appliance with more stars may still use more electricity overall than a smaller, less highly rated model. Check current models and running-cost estimates before buying, and follow the manufacturer’s instructions for efficient use.
