Saving Green, One PC at a Time

Loew-Brenn Computer Lab

Most people do not think of their PCs as a large problem for the environment. Add all of the personal computers, servers, monitors, printers, and peripherals together and it is easy to see that the technologies of the last 20 years are a major factor in the amount of energy we consume each year. Luckily these devices come prepackaged with many energy saving techniques. Now we just need to know where to look to make sure we are taking advantage of these quick simple fixes.

Here are a few things you can do to make sure you are running an efficient low power computer.

1. Enable monitors and hard drives to turn off after 15 minutes.
2. Check to make sure the system will enter stand-by mode after 30 minutes of inactivity.
3. With newer LCD monitors, turn off the screen saver and allow your monitor to shut off after 15 minutes. Also, dimming the brightness uses less power.
4. Energy Star computers are much cheaper to run. Upgrade old PC systems to newer compliant systems.
5. Unplug printers, speakers, scanners, and cameras when they are not in use.
6. Laptops use less power than full desktop PCs, utilize the smaller laptop as much as possible.
7. Check programs and utilities to make sure they are not preventing your computer from entering into stand-by mode.

  1. Now I am telling you an LCD monitor uses about one-third the power of a CRT display with the same screen area, according to monitor vendor ViewSonic. Visit ViewSonic’s LCD vs CRT page for more on the benefits of LCDs over CRTs. You’ll also save energy by switching from a desktop PC to a laptop, and from a laser printer to an inkjet. A typical laptop uses about one-quarter the power of a similarly equipped desktop.
