Compare the Energy Rating label’s star rating and estimated annual energy use, rather than relying on stars alone. Check appliances with a similar size or capacity, because a larger model may use more electricity even if it has more stars. You can estimate running costs by multiplying the label’s annual kilowatt-hours by your electricity rate, then consider the purchase price, features, standby use and expected lifespan. For current label information and comparison tools, check the Australian Government’s Energy Rating website.
