Recent studies have shown that the electricity required to power household appliances when they are in a stand-by mode accounts for approximately 5% of total annual residential electricity consumption. Using DOE data from 2004, this means that 64 million MWh of electricity goes to stand-by power, equivalent to the output of 18 typical power stations. A significant contribution to global warming!!
So don't leave that computer in stand-by mode - turn it off when you are not using it.
Your children will be glad you did!
