UNH IT Power Management

Green Computing at UNH

UNH is a nationally-recognized leader in sustainability and energy conservation. In May 2008, UNH President Mark Huddleston issued a memorandum to the University community, asking for students, faculty and staff to assist in helping to reduce our collective energy costs by 5% (per year). UNH IT is committed to helping President Huddleston achieve this goal by educating students on the matter. The following information will help UNH reduce costs and save energy in regards to computer usage.

You can help save energy by...
Enabling Your Computer’s Power Management Feature
This simple step will help you save both the battery life on your computer, and energy costs for the University. If all 6000 students living in residence halls activated power management the annual savings would be the same as taking 294 cars off the road.

Here’s how to enable the Power Management feature on your computer:

Windows 8
  1. Select the WIN and X keys together.
  2. Select Power Options.
  3. Select Power saver.
  4. Close the Power Saver window.
 
Windows 7
  1. Select Start.
  2. Go to the Control Panel.
  3. Click on Power Options.
  4. Choose Power Saver.
  5. Close the Power Saver window.

Windows Vista

1. Select Start.
2. Go to the Control Panel.
3. Control Panel has two view options:
        >For Theme View, click on ‘System and Maintenance,’ and then choose  Power Options.
        >For Classic View, click on Power Options.
4. Choose either the Balance or Power Saver setting.
 
Windows XP
1. Select Start, then Settings, Control Panel and Display.
2.Select the Screen Saver tab.
3.Select Power under the ‘Monitor Power/Energy Star’ section.
4. Choose Turn Off Monitor after 20 minutes.
6. Choose Apply.
 
Macintosh OS X
1.Select System Preference’ from the dock.
2.Select ‘Energy Saver.
3. Under the Sleep tab, enable your computer, display or hard drive to go into Sleep mode after a period of inactivity.
 
Additional Info
Sleep Is Good
By adjusting the Power Management feature in the Windows Control Panel and ‘Energy Saver’ Preference pane on a Mac you can:
1) Set your screen to go to sleep after 5 minutes.
2) Set your computer to go to sleep after 15 minutes.
3) Disable Screen Savers - these save no power, and are no longer necessary to
prevent screen damage.
 
Off Is Better
Though sleeping electronics consume far less power, turning them off is drastically more efficient.
1) Turn off your computer monitor when you leave.
2) Schedule your computer to turn on and off based on your use schedule (no,
this does not affect its life-span).
 
Unplugged is Best
The very best way to save power is to use a power strip to cut power to electronics that are off at night or on weekends, as they still drain power in this state. This also helps protect your electronics from power surges.
 
More Energy Saving Tips

• Don’t use screen savers. Screen savers and slideshows use a huge amount of
energy. Consider powering down your monitor instead (when not in use).
 
• Power down computer peripherals when not in use. These include
computer speakers, external hard drives, scanners, and printers.
 
• Don’t print unless necessary. Reading text on screen can be less pleasing to
the eye, but consider this as an alternative to printing documents out for review unless necessary.
 
• Turn your computer off when not in use. According to the Department of
Energy, a computer left continuously running will emit 2161 pounds of CO2 a year and will cost $45 to power at $.0372/kWh.
Computer Purchasing Tips
• Buy a laptop. Notebook computers use 80% less energy than desktops.
 
• Buy an LCD Flat-screen. LCD flat screen computer monitors use 30% less
energy than standard CRT monitors and take up a lot less room.
 
Buy an EnergyStar® recommended computer. An Energystar® compliant
computer uses 70% less electricity than units without power management features. The UNH Computer Store sells a number of Energystar® compliant models.
 
Computer Disposal
UNH students can dispose of their unwanted personal computers (towers, monitors, printers, mice, and keyboards) with Environmental Health and Safety. Call 862-4041 for more information.
