That's NOT taking into account if you have power saving options turned on. Putting your computer in sleep or standby can save you almost the same amount!

Want to save more money? Unplug each device you're not using. A medium sized television (even the new LCDs) suck down as much as 5 watts per hour even when they're turned off. Almost all electronics built in the last 10 years use power even when they're turned off. The computer uses about 5 -10 watts / hour even when it's off, the cell phone charger uses almost the same amount of electricity when it's not charging your phone, as when you're charging a fully drained cell phone battery. And since you mentioned the computer, the printer is a HUGE energy hog, especially laser printers. Lately (thankfully) printers have had their auto power saving features enabled by default. Imagine your workplace though... Most companies turn off the power saving features on their printers because it can cause backups at the printer(s), so all night the printers are left on and suck down power (as much or more than a 100 watt light bulb!!!) Multiply that by the number of printers in your office and you'll find that a small office at night can use more electricity than your home's air conditioner at noon on a hot July day!
