Save a buck: Switch off the computer
Does not compute: It's easy to remember to turn off a light when it's not in use, but how often do you switch off your computer when you're not surfing the Web or reading e-mail? Computers, especially older computers, can run at up to 250 watts. Would you leave two 100-watt bulbs burning most of the day?
Sleep it off: You can significantly cut that to 1 to 6 watts by going to your computer's system preferences and setting your computer to "sleep" when it goes unused for 5 or 10 minutes. Climatesaverscomputing.org says you can save up to $60 a year by using your power management settings. Using a screen saver doesn't count. When a screen saver is running, so is the computer.
The surge is working: Better yet, buy a surge protector power strip, plug in your computer, printer and other peripherals and turn them all off with the flick of a switch (Although you'll want to shut down your computer before hitting the strip's switch.) Even when turned off, computers and printers still draw a small amount of current, which can add up over time.
Old nerds' tale: Oh, and you're not saving wear and tear on your computer by leaving it on. That misconception is as outdated as MS-DOS.
