Some Myths and Facts about Power Management
What is Green Computing?
Green computing is the environmentally responsible use of technology.
- Enable power management on your computer.
- Power down the computer and monitor when not in use.
- Consider plugging your computer and peripherals into a power strip with an on/off switch and turn the entire power strip off when not in use.
- Printing Tips
- Think before you print. Do you really need a paper copy? If yes, you can print 2 pages per sheet or multiple slides per page.
- Use recycled paper if possible. The college purchases 30% post-consumer recycled paper.
- Use Print Preview to review your job before printing it.
- Print in black and white whenever possible.
- Print two-sided whenever possible.
- Reuse unnecessary print jobs as scratch paper.
- Advertise events, parties, etc. electronically or with chalk instead of print-outs.

Enable Power management on your computer.
Every day energy is wasted by computers and monitors that are left on when not in use. By simply putting the hard drive and monitor to sleep after a short period of inactivity, huge energy savings can be realized. The computer should wake up with a quick click of the mouse or by pressing a key on the keyboard. In some cases, you will need to press the power button briefly to wake the computer up. Also, be sure to shut down your computer before leaving for the day and over weekends.
Myth: Computers have a shorter life when you turn them on and off frequently.
Fact: Hard disks in PCs older than 10 years did not automatically park their heads when shut off, leading to disk damage from frequent on/off power cycling. Newer PCs are designed to handle over 40,000 on/off cycles.
Myth: Turning your computer off uses more energy than leaving it on.
Fact: The surge of power when a computer is turned off lasts a few seconds and is insignificant compared to the sustained energy used in keeping it on during periods of inactivity.
Myth: As long as the computer is off, it's not using any power.
Fact: As long as they are plugged in, your computer and other electronic devices continue to use electricity – even when they are turned off or in standby mode. A computer uses up to 10 watts when it is turned off but still plugged in.
