'Green Screens' Campaign: Saving Energy with Screensavers and ENERGY STAR ®
Screensavers can increase electricity usage:
Screensavers are fun, but did you know that running a screen saver can cause your computer to use more electricity? Estimates are that over One Billion Dollars may be wasted annually in the United States alone.
This can result in:
Higher electricity bills - for the computer itself.
Higher electricity bills - for additional air conditioning needed to cool the room, due to higher heat output of the computer.
More fossil fuels being burned with more pollution and greenhouse gas emissions, in order to generate the electricity.
More wear and tear on your computer hard drive.
Have your cake and eat it too?
It's possible to enjoy your screensaver AND save energy, by using the built-in energy-saving features of your computer.
How? By setting the screensaver to come on after a certain delay,
and then, after a second, longer delay, having the display or the entire computer "sleep."
This prevents your screensaver and monitor from staying on 24 hours a day.
Research suggests that if your computer is inactive for more than 30-60 minutes, there is a good chance that no one is there to enjoy the screensaver, so you might as well have the monitor or computer turn off to save power.
