Power Down Computers
According to Energy Star, turning off 1,000 computer monitors will save 200,000 kWh per year. Setting your computer to sleep mode reduces energy consumption by at least 87%. To further reduce your computer’s energy consumption, turn it off when not in use; enable the Power Management feature; and don’t use a screen saver.
EPA recommends setting computers to enter system standby or hibernate after 30 to 60 minutes of inactivity. You can save up to $75 or more per computer by activating system standby or hibernate features. To save even more, set monitors to enter sleep mode after 5 minutes of inactivity; the lower the setting, the more energy is saved.
