SAGE Advice: October 2010 Archives
Setting your power management to activate a screen saver after a period of being idle can be a huge waste of energy--especially if the screen saver runs all night. In most cases, screen savers use more energy than a computer consumes while it's being used. Instead, set your computer to go into sleep or stand-by mode.
If you work in an office on campus, this can save a lot of energy. For an office with 25 computers, you can save $400 per year by using sleep mode instead of a screen saver during the workday. This adds up to 5,000 kilowatt-hours and more than 6,000 pounds of carbon dioxide.
Did you know? Screen savers were originally invented to prevent something called phosphor burn, which "etched" long-standing images into the screen. Phosphor burn is no longer much of a concern with today's monitors, so you can turn the lights out on your virtual aquarium.
