Ways to reduce your energy bill now that won't cost a thing

Ready to start saving? Targeting the following areas of energy use will help you start reducing energy around your home.

Minimise hot water use

Hot water is potentially the single biggest source of energy use in your home. Wash clothes in cold water and only wash full loads. Run the dishwasher only when it's full and scrape plates first; then cold water rinse if they need it. Fit a low-flow showerhead (a cost that will pay for itself in no time) and take shorter showers.

Control your heating and cooling costs

Once your hot water usage is under control, heating and cooling are usually the next biggest energy guzzlers around your home.

In winter, set your heating thermostats between 18 and 20°C. In summer, set your cooling thermostats between 25 and 27°C. Every extra degree increases your heating and cooling energy use by between 5 and 10%. Close internal doors and only heat or cool the rooms you are using.

Stop heat leaking out of windows

Up to 40% of the heat in your home could be leaking out your windows. In winter, open curtains to let the sun in and close curtains before it gets dark to keep the heat in—especially while your heater is on. In summer, close curtains during the hottest part of the day. At night you can open curtains and windows to let warm air out and cool breezes in.

Use appliances wisely

Appliances could be responsible for as much as 33% of your energy bill.

To keep costs down, turn off additional fridges and freezers when not needed and think about getting rid of these permanently. Use lids on pots while cooking and fill the kettle and pots with only as much water as you need. Dry clothes on the line not in a dryer—it's free!

If you have a pool, reduce the filter’s running time to the safe minimum set out in the manual.

Turn everything off at the wall

Standby power can account for more than 10% of your household electricity use.

Any items with a little light on or clock are using power, and your mobile phone charger is drawing power even when your phone is not plugged into it. Turning off appliances like these at the wall when you're not using them is a very easy way to save energy.
