Contrary to the popular belief, screensavers are not energy savers. In fact, computers use more energy to run a screensaver than they do just sitting idle with the monitor turned on.
By using sleep mode instead of a screensaver, you could save $10 to $30 per year. If you were prone to leaving your computer on all night with the screensaveer, your annual energy cost savings could total more than $100.
Go green by conserving energy & turn your computer monitor’s to sleep mode.
