-Turn off your appliances at the power-point. Remember, if there is still a little red light on then power is being used. Have you thought about remote switching so you have no need to reach behind your TV?
-Use your dishwasher on a shorter cycle and let your dishes air dry.
-Replace your lights with something more energy efficient. We are always excited when customers decide to make the switch to LEDs.
-Turn off your lights. This is obvious for when you’re not in the room, but consider if you need them when you are in the room too. Could you open the curtains instead? Have you thought about LED skylights? They are solar powered during the day but with the option of mains power at night. What about sensors or installing timers in the bathroom and toilet.
-Change thermostat settings so that your air conditioner isn't set quite as cool and your hot water isn't set quite as hot.
-Don't use appliances when it's not necessary. Turn off the second fridge between parties and don't run the washing machine until you have a full load. If you do need to keep a second fridge running try to locate it somewhere cool rather than the stinking hot back shed.
-Get rid of your kids. Ok this ones a joke but gosh they're energy wasters! If my wife and I got a dollar for every time we said "turn off the lights..." we'd have enough money to stop worrying about the electricity bill ;)
Happy summer Canberra!
