Turn off your screen saver. Did you know the EPA has estimated that using a computer's "sleep mode" reduces its energy consumption by 60 to 70 percent and, on a large scale, ultimately could save enough electricity each year to power Vermont, New Hampshire, and Maine, cut electric bills by $2 billion, and reduce carbon dioxide emissions by the equivalent of five million cars? A screen saver that displays moving images causes your monitor to consume as much electricity as it does in active use. A blank screen saver is only slightly better but that reduces energy consumption by a small amount.
The best screen saver is also the best energy saver: turn off your monitor when you're not using it. The next best idea is to use your computer's power management feature to automatically shut the monitor down when it is not in use. Despite the rumors, leaving your computer on overnight is in fact less efficient that shutting it down and booting it up the next day. Turning off your computer will decrease the amount of energy it uses, reduces its mechanical stress, prolong its life. |
