It is surprisingly simple to make changes that help you take charge of your power bill.

An average Australian family can make changes that add up to hundreds of dollars a year in savings. For example:

• Hot water is often the biggest energy user in your house. Washing clothes in cold water can save you around $115 per year.
• Appliances are responsible for as much as a third of your energy bill. Get rid of the second fridge and save yourself around $140 per year.
• Switch your electric clothes dryer off and use the clothesline. Wind and sun can save you around $63 per year.
• Standby power is the invisible enemy. Switch gaming consoles off at the wall and save around $150 per year.
