Another thing to remember is that as long as any appliance is plugged in (even when the switch is off) there is a certain amount of electricity trickling through. This can add up to quite a dollar amount over a year. So all small appliances, washing machines etc should be unplugged when not in use. TV's are the worst offenders, and don't forget plasmas can be a bit of a fire hazard if insufficient gap between the wall and the unit and if dust builds up. Stay safe everyone.
