Overview
Why have your computer running if you’re not using it? This easy trick can save a significant amount of electricity because much of the power used to run your computer goes toward lighting the screen.

Tips & Tricks
Use sleep-mode instead of a screen-saver. Screen savers that display moving images on your screen still require power to keep the screen lit, whereas the screen is off in sleep mode.

Set you computer for five-minute sleep mode. On Apple computers, you can find the screen settings under “System Preferences > Energy Saver.” On Windows, go to “Turn off computer” and then select either “Stand By” or “Hibernate.”
