The South Australian government estimates that the average household can save around $215 per year by switching off their appliances1 (computers, televisions, washing machines and so on) rather than leaving them on standby.
Speaking of switching off, your household lighting alone generates between 8 and 15% of your energy costs2. So remember to turn off lights when you’re not using them.
If you haven’t replaced all of your old halogen light bulbs with LED bulbs, now’s the time to do so. They’re much cheaper to run and last longer.
When buying new appliances, look for ones with a higher energy efficiency rating. This can save you money in the long term.
You may also want to consider all of the appliances you already have.
A second fridge or freezer may be useful, but it’s worth asking whether you really need it or if it’s just draining money.
