Today, a large part of the world uses computers, and even 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 generate that energy.
First, when you shop for your next computer, remember that laptops use less energy than desktop computers. Although they can be energy efficient, even when turned off and the battery fully charged, if you leave them plugged in, they continue to draw power. You must unplug the power supply/charger from the wall (or turn it off with a switchable power strip). This will remove another “phantom power” charge from your electricity bill.
This is also true for desktop computers and monitors. They continue to consume “phantom power” even when turned off. Put them on a switchable power strip with surge protection and turn off the system when you’re away from your desk for an extended period; 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 power management features on your computers and monitors and turn off screen savers, or select a “blank screen” for your screen saver. They then use power only when you are using them and “go to sleep” and use less power when idle for several minutes. Also, if you are going to be away from your computer for several hours, and at the end of the day, use the hard shutdown procedure for your computer (not “sleep” or “hibernation” mode). Then, use your switchable power strip to turn off your computer, monitor, speakers, and other external devices so they don’t draw up “phantom power” that costs you money while you sleep.
The important thing is to always think about energy use when buying and using your computer. You’ll save a huge amount of energy, lower your energy bills, and reduce the resources needed to generate that energy. Even if you create the power with your own wind and solar generators, if you use less for your computing, you’ll have more for other things.
