Set your home computer to automatically hibernate/sleep after a short period of inactivity.
Description
Set your computer to automatically hibernate/sleep after a short period of inactivity. When in sleep mode, the display and computer go into a low power consuming mode. The machine keeps the current operating settings, so if you have a file or an application open, it will still be open when you reactivate the computer. This is not the same as using the screensaver; a screensaver requires both the display and computer to continue to work, and consume energy, when you are not actively using the computer.Assumptions We Made
Assumes LCD flat-panel display (most popular now) with 65 Watts at full power versus 3 Watts in sleep mode, sleeping 20 hours per day, being used 4 hours per day, every day of the year. Otherwise, would be left on all the time. Does not include additional savings earned when hard drive spins down and so on. Assumes that once you do this, it will stay in effect for 5 years, since most people replace their computer within 5 years.Impacts
