A large portion of the world today uses computers, and, though they consume only a small amount of power compared to a clothes dryer, they still consume power. Using them wisely and energy efficiently saves you money on your energy bills, and reduces the resources needed to create that power.
First, when you buy your next computer, remember that laptop computers use less energy than desktop computers. Energy efficient though they may be, even when switched off and the battery fully charged, if you leave them plugged in, they continue to draw power. You should unplug the power supply/charger from the wall (or turn it off with a switchable power strip). This will take another “phantom power” load off your electric bill.
This is also true of desktop computers and monitors. They continue to draw “phantom power” even when turned off. Put them on a switchable power strip with surge protection and turn the system off when you are away from your desk for an extended period — you will save money.
Many people believe that screen savers on laptops and computer monitors save energy. Unfortunately, it just doesn’t work that way. When the screen saver takes over, the monitor is still on and consuming its full rated power. Turn on the Power Management features in your computers and monitors and deactivate the screen savers, or select a “blank screen” for your screen saver. They then use energy only when you are using them and “go to sleep” and consume less power when they are inactive for several minutes. In addition, if you will be away from your computer for several hours, and at the end of the day, use the full shut down procedure for your computer (not “sleep” or “hibernate” mode). Then use your switchable power strip to turn off power to the computer, monitor, speakers, and other external devices so they do not consume “phantom power” that costs you money while you are sleeping.
The important thing is always think about energy use when you purchase and use your computer. You will save a great deal of power, lower your energy bills, and reduce the resources needed to create that power. Even if you create the power with your own wind and solar generators, if you use less for your computing, you will have more for other things.
