Green IT: How Individuals Can Reduce Energy Costs & Protect the
Envionment
John Thompson, PhDBuffalo State College
Why Use Power Management?•Save money.
▫Gartner, Inc. - well-managed 2,500-PC organization uses 43% less power per year than unmanaged one - saving $43,300/year
▫DOE – save $50/computer/year
•U.S. federal government has almost 7 million civilian employees – do the math.

Power Management
• Turn off computers & printers if not in use▫ Search on “PC shutdown software” for solutions
▫ E.g., BigFix Power Management, Faronics Power Save & NightWatchman
• Use low power "sleep" mode ▫ Can still download & install updates & perform
maintenance tasks
▫ Wake on LAN (WoL) Dr. John Thompson

When not in use,
turn off the juice.
Power Management
•Reduce time before entering sleep mode
•Disable screen saver
•Replace CRT monitor with an LCD monitor

Power Management• Turn off components at end of day
▫ Prevent “vampire power" or “phantom load”
• Connect system to a power strip & turn off strip after shutting down components
• Plug laptop’s AC adapter into power strip
• Use a smart power strip

Why Worry About Printing?•Federal employees print 30 pages each work
day•92% of employees print more than they need•Workers discard 35%of the paper they print
out ▫Federal government spends nearly $1.3
billion annually on employee printing▫So federal government spends $440.4
million each year on unnecessary printing

More Printing Savings• Use print preview and “shrink to fit”
• Only print the selection you need
• Switch to draft mode to increase printing speed
• Duplex printing (both sides)
• Use http://www.greenpdf.com/

Inkjet Printers•Use 80-90% less energy than laser printers
Example: HP 4V laser printer Printer power consumption
HP 4V – 28-110 watts standby, 380 watts printing HP 4315 Officejet All-in-One – 18 watts maximum

Other Suggestions•Purchase green – Design RFPs & purchasing
practices favoring/requiring energy-efficient (Energy Star & Electronic Product Environmental Assessment Tool - EPEAT) technology▫Federal agencies required to purchase at least
95% of EPEAT registered products in all relevant electronic product categories
• Join ENERGY STAR Low Carbon IT Campaign•Participate in Power IT Down Day in 2010

More Suggestions •Change your subscriptions to online – not
paper – use SnagIt or SnipIt type programs to grab/save info
•Optimize computer performance•Decrease screen brightness•Change from XP to Vista…to Windows 7?•Use laptops instead of desktops• Install energy monitoring software – e.g.,
Edison•Have a professional energy assessment

Online
• Increase use of the Internet and your Web site▫Put information on Web pages, wikis & blogs
instead of making paper copies
•Online courses consume nearly 90% less energy & produce 85% fewer CO2 emissions – 2005 report▫Use less paper than traditional classroom ▫Assign online texts or Internet sites▫Use course management systems
Dr. John Thompson

Online
•Use desktop Web conferencing to reduce trips ▫Ex. - WiZiQ, Dimdim, WebEx, Elluminate
•Outsource organization’s e-mail (e.g., Google Gmail) to the “cloud”
•Telecommute or use VPN connection
•Online subscriptions instead of printDr. John Thompson
