Computers and Monitors
Your computer and monitor are energy vampires that use power even when they are turned off. At 400 watts per hour, each desktop computer in your house is costing 4 cents an hour to run.
To save energy, plug desktops, monitors and laptops into a power strip that you can turn off when the machines are not in use. Laptops are more energy efficient than desktops, but leaving them plugged in will drain energy even when you’re not using them.
