Appliances

Turn off electrical appliances (computers, TVs, DVD players) overnight and when not in use.
When purchasing new appliances buy a high star rated model to save energy and water. The more stars the more savings! Find out more about energy ratings.
If you have time-based billing, use dishwashers, washing machines or dryers during off peak times to save money (after 10pm and before 7am).
Wait until you can wash with full loads rather than washing small loads frequently.
Dry your washing on the clothes line rather than using a drier as often as possible.
Program the computer to have a blank screen when idle as screensavers will not reduce energy use.
