Energy Saving Tips: - Home Office Equipment

Tips
  • Consider purchasing energy-efficient computer systems and monitors when you are replacing them. Make sure you enable your computer's energy-saving features.
  • Some newer computers and other electronic equipment have a "sleep" or "stand-by" mode that allows them to start immediately when you turn them on. However, that means they are constantly drawing a small amount of energy. When possible, you should switch this option off.
  • Be sure to at least shut off the computer screen, as 60% of the power used by a computer is used by the monitor! (The other 40% is used to keep your hard drive spinning and to power electronics.
  • Put your home entertainment systems on a power bar and turn off the bar when you are not using them. (Components without memories, clocks and timers, of course.)
  • Unplug infrequently used TVs, as all continue to draw power even when turned off.
  • When you are ready to replace a piece of electronic equipment, seriously consider purchasing an Energy Star® model. Energy Star® equipment are between 15 percent to 40 percent more efficient than older models, and will save you energy for years to come.
