Put your home entertainment system on a power bar and turn off the bar when you are not using the components (those without clocks and timers, of course). The same can be done for your computer and related components.
Unplug battery chargers as soon as the device is fully charged or when the charger is not being used. A battery charger continues to draw power even when the device it is charging has been removed.

Shut off your computer screen.
More than half of the power used
by a computer is used by the monitor!
Activate the power management features of your ENERGY STAR qualified computer and monitor. Letting the equipment "sleep" will do wonders for your electricity bills.
Did you know? Computers, televisions and other home electronics use electricity when they are not in use. This is known as "standby power" loss.
In an average household, the combined energy consumption of home electronics (when turned off) is equivalent to that of a large refrigerator.
