1. WASHING MACHINE
Choose a front-loader on your next buy - it uses up to 50 per cent less energy than top-loaders and 40 per cent less water.

Air-dry clothes instead of using an electric clothes dryer.

2. KETTLE
Boil water only when needed. Use a thermos flask to store hot water instead of an electric airpot and save $300 a year.

3. KITCHEN SINK
Wash dishes in a plugged sink and don't leave the tap running.

4. REFRIGERATOR
Choose a four-tick model over a one-tick model and save about $100 a year.

Buy the smallest model that meets your family's needs - larger models generally use more energy.
