Green Computing April 12, 2011
Fact or Fiction? • Using a screen saver saves my monitor and/or energy. • Turning my computer off and on reduces the life of the hard drive. • I can use blank sides of paper to print on for a draft copy.

How Much Energy Does Your Computer System Use? Laser printer - 100 watts or more when printing; much less if idling in a “sleep mode” Ink jet printers use as little as 12 watts while printing and 5 watts while idling • 65 - 250 watts of electrical power • 150 watts for CRT vs. 50 watts for an LCD display • Laptop - 15 to 45 watts http://ecenter.colorado.edu/energy/projects/green_computing.html http://www.wisegeek.com/how-much-electricity-does-a-computer-use.htm
How Much Can You Save? • Having a computer on 40 hours per week instead of all the time, uses $40 less annually in energy costs. • Assumes 85 watts computer and $0.083/kWh • http://www.energystar.gov/index.cfm?c=power_mgt.pr_power_mgt_users • http://michaelbluejay.com/electricity/howmuch.html

Energy Efficient Computing • When not in use, turn off the juice
Energy Efficient Computing • Screen savers save no energy and do not save screens
Energy Efficient Computing • Screen savers save no energy but Power Schemes do In Windows 7, search for “Choose Power Plan” and “Edit Power Plan” http://www.energystar.gov/index.cfm?c=power_mgt.pr_power_mgt_users
Old Computers • Repurpose, Reuse or Donate • Recycle • There may be a charge • Special days during the year • Households vs. companies • Sample: Best Buy • Websites • Michigan’s Electronic Waste Takeback Program • Example company: GEEP
Computer Recycling Video • Recycling video • Things to look out for • Where are they taking your equipment? • What are they doing with your equipment?
Before You Print… • Do you really need to print? • Did you proofread your document? • Did you print preview to ensure proper formatting? • Do you need all the pages of the document printed?
Reduce Paper Waste • Print as little as possible • Don’t printout emails • Try to email documents instead of faxing • Smaller font sizes and margins on large documents can save a good deal of paper • Try circulating items instead of copying • Use double-sided printing and copying • Reuse paper only printed on once
Reduce Paper Waste • Use Review features within Microsoft Word such as Track Changes, Comments, and Ink—no need to print to edit documents • Be careful where you print • Copy the minimum that you need • Teach students these lessons • Accept work electronically
Other Waste Reducing Steps • Don’t print in color if you don’t need to • Make laser prints over inkjet prints • Make multiple copies on copiers • Use 100% post consumer recycled paper
Don’t Make Photocopies Don’t Make Photocopies • Scan it • You can store it digitally • It’s already digital? • Email it • Don’t want people to change it? • Turn it into a PDF
Going Paperless for Earth Day • Pledge to refrain from using any paper or accepting any work on paper this Earth Day http://teachpaperless.blogspot.com/
Other Green Computing Practices • Recycling • Recycle batteries, ink cartridges and print toner
Before You Buy • Can you upgrade instead? • Buy only “Energy Star” computers, monitors and printers • Buy laptops not desktops • Buy ink jet printers, not laser printers for home use http://www.greenpeace.org/international/campaigns/toxics/electronics/how-the-companies-line-up
