HELP CONSERVE THE UO!
REDUCE GLOBAL WARMING, CONSERVE ENERGY AND SAVE $$$

As you know, computers are one the largest individual energy use items on campus.  The amount of computers utilized on campus is growing and taking it's toll on our campus energy consumption, not only in the amount but also how we manage our computer use.

With rising energy costs and demand on campus, I am writing you to enlist your assistance in helping the University of Oregon reduce it's energy use by making adjustments to how we manage our computer use.

A computer left on continuously, will emit 2161 pounds of CO2 in a year and cost ~$50/year to power at our current rate of $.038/KWh.  Utilizing power management features and shutting off equipment at night and on the weekends could save the University of Oregon over $300,000/year in energy costs (based on 12,000 units, a conservative estimate for computer use on campus).

By implementing easy to use power management tools (described through link below) and taking the time to shut off your work station computer at night and on the weekends , we can continue to work together to reduce our campus energy use.

Please take a minute to read the Green Computing Guide for more specific information on reducing the impact of campus computer use. Additionally, please share this within your departments and assist me in getting the word out on this important issue.


SHUT IT OFF AND TRULY SAVE ELECTRICITY
Below you will find information on setting your computer to a sleep mode or minimized energy use mode. Truly even with sleeper modes, the computer and monitor are still using electricity. Shutting of the monitor when leaving the room for short periods of time and shutting down the computer at the end of the work day, is the absolute best method for saving energy.

Energy Saving Tips for PC's

Creating a “Green” Machine:

Turn On Power Management Features :
The UO encourages all computer users to enable their Power Management Features.

•Windows 95– Select Start, Settings, Control Panel, and Display. Select the Screen Saver tab. Choose a predominantly black screen saver and set it to wait 5 minutes. Click the Low-Power Standby box and set for 10 minutes. Click the Shut Off Monitor box and set for 20 minutes. Click Ok or Apply.

•Windows 98/ME/2000/XP– Select Start, Settings, Control Panel, and Display. Select the Screen Saver tab. Choose a predominantly black screen saver and set it to wait for 5 minutes. Click on Settings to reach the power management settings. Click the Shut Off Monitor box and set for 10 minutes. Click Ok or Apply.

•Windows NT– does not support Energy Star, so you cannot activate the low -power settings through the Control Panel. You still can select a dark desktop background and screen saver. Energy Star still can be activated through the computer's set-up
program, which varies among computer models. Contact your computer support staff if you need assistance.

•Macintosh– Select System Preferences from the dock (OSX) or click the Apple and select Control Panels (OS9). Select Energy Saver. Under the Sleep tab you can enable your computer, display, and hard drive to go to sleep mode after a period of activity.

Check with other operating systems to see what power saving features are available on your computer.

Recycle the Information:
In knowing the facts about Green Computing, please encourage fellow students, friends and co-workers to “think green” when using computer equipment. With everyone's increased cooperation we can reduce costs at the University of Oregon and at home, while at the same time, conserving our valuable natural resources.

Common Computer Myths :
Myth: It is bad to turn off the computer.
Truth: Computers are now designed to handle 40,000 on/off cycles. This is considerably more cycles than the average user will initiate in the computer's 5-7 year life span. Turning your computer off helps reduce heat stress and wear on the system.

Myth: Turning your computer off uses more energy than leaving it on.
Truth: The surge of power used by a CPU to boot up is far less than the energy used by the unit when left on for over 3 minutes.

Myth: Screen savers save energy.
Truth: Screen savers were originally designed to help protect the life span of monochrome monitors which are now technologically obsolete. Most screen savers do not save energy unless they actually turn off the screen or, in the case of laptops, turn off the back light.

Myth: Network connections are lost when a PC goes into low-power/sleep mode.
Truth: Newer computers are designed to sleep on networks to prevent loss of data or connection. CPU's with Wake on LAN (WOL) technology built-in to network cards can be left in sleep mode overnight to wake-up and receive data packets sent to the unit.

Campus E-Waste Recycling: Contact Sheree Johnson to recycle E Waste: shereej@uoregon.edu
Do you have old and unused electronics stored away?  University of Oregon now recycles:
· CPUs, Monitors, and Printers
· Floppy Disks and Compact Discs
· Toner Cartridges and Ink Jets
· Cell Phones, Palm Pilots (PDA's)
· 2-Way Radios/Beepers/Pagers
· Audio and Video Tapes
· Batteries and Accessories
Recycle items in depositories outside dining halls, via campus mail, or by direct pick-up.

OTHER THINGS TO DO WHILE COMPUTING TO SAVE RESOURCES
1. Reduce paper use, set all printers to double side mode, print on both sides of paper
2. Used paper makes great scratch paper and paper that can be used as draft copies or non-essential documents
3. Extend margins for printing on top, bottom and both sides, this can be done through page formatting
4. And...be conservative on printing as it can waste paper and printers utilize electricity and ink that can have a big impact on the energy and resource bill from your offices
5. Think before printing and utilize email and electronic bulletin boards to post information as much as possible

Computing the Savings :
A computer left continuously running will emit 2161 pounds of CO2 in a year and cost $45 a year to power at $0.0372 per kWh. (a major cause of global warming).

Turning a computer off at night so it runs only 8 hours a day computes to a reduction of 810 kWh per year, or a 67% yearly savings.

By turning off computer units at night, University of Oregon can save 9,720,000 kWh per year. This amounts to $360,000 per year saved (for 12,000 units at $0.0372 per kWh).

Energy Star Investment:
Energy Star® is an important and automated means for realizing significant power savings. An Energy Star compliant computer in sleep mode uses 70% less electricity than units without power management features.

A Standby setting (available only in Windows 95) can drop power over 90 percent from maximum. Screen recovery occurs within 1-4 seconds by hitting a key or pushing a mouse. The Suspend setting can drop power almost completely, although screen recovery can take up to 10 seconds.
