Myth: Switching off an appliance prevents it from using electricity
Busted: Most appliances continue to draw energy even when they are not in use. Once you’ve finished using an appliance make sure that you switch it off at the wall and pull out the plug.
Myth: Using electricity at night is cheaper
Busted: If your appliances are wired to the most common residential Tariff 11, it is the same flat rate day and night.
Myth: Leaving computers, lights and other appliances switched on uses less energy than switching them off and back on again
Busted: The amount of energy used to switch an appliance on is very small compared to the energy used to keep it running when it’s not needed. As a general rule: switch off a device whenever you aren’t using it.
Myth: You can’t insulate an old home - it’s not cost-effective
Busted: Insulating your property will reduce your need to use heaters and air conditioners, resulting in cheaper energy bills.
Myth: New homes are more efficient
Busted: This is not necessarily true. The energy efficiency of your property is to do with how, and not when, it was built and designed.
How to get the most out of your energy efficient appliances
Using energy-efficient appliances incorrectly may cancel out the savings made from buying a product with a high star rating. For example, a fridge that isn’t properly sealed needs to work a lot harder to keep temperatures cooler – doubling or even tripling your bills.
To get the most out of your energy efficient appliances:
- Maintain them with regular cleaning and checks.
- Switch devices off when they are not in use.
- Consider where your appliances are positioned. A fridge positioned in direct sunlight or close to heat sources such as ovens and dishwashers will use significantly more energy to keep cool.
