Look for appliances with a high Energy Rating label, but compare the star rating and estimated annual energy use for the model size you need. Efficient options can include heat-pump hot-water systems and dryers, induction cooktops, inverter air conditioners and fridges with strong ratings. Choosing the right capacity, using eco settings and maintaining filters can also reduce electricity use. Check the Australian Government’s Energy Rating website for current labels and compare purchase prices with likely running costs before deciding.
