  1. Green Computing April 12, 2011

  2. 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.

  3. Green Computing? “Green computing is the environmentally responsible use of computers and related resources.” Source: http://searchdatacenter.techtarget.com/sDefinition/0,,sid80_gci1246959,00.html

  4. 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

  5. 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

  6. 15%… Worldwide Percentage of money spent on powering your computer dedicated to computing; the rest of the money ($250 billion) is spent on energy wasted in idling. Source: http://planetgreen.discovery.com/go-green/home-electronics/home-electronics-statistics.html

  7. Energy Efficient Computing • When not in use, turn off the juice

  8. Switch Off the Strip

  9. Energy Efficient Computing • Screen savers save no energy and do not save screens

  10. 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

  11. 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

  12. Computer Recycling Video • Recycling video • Things to look out for • Where are they taking your equipment? • What are they doing with your equipment?

  13. Reduce Paper Waste

  14. 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?

  15. 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

  16. 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

  17. 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

  18. 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

  19. 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/

  20. Other Green Computing Practices • Recycling • Recycle batteries, ink cartridges and print toner

  21. 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

  22. It’s Not Just Computers

  23. Green Your Electronics • Tree Hugger Info

  24. Digital Cameras & Rechargeable Batteries http://www.steves-digicams.com/digi_accessories.html

  25. Cell Phones • Never throw a cell phone in the garbage • Recycle it! • You can get money for it. • www.cellforcash.com

  26. Lessen Your Impact • Offset Your Carbon Footprint • Carbonfund.org • Carbonneutral.com • www.ecobusinesslinks.com/carbon_offset_wind_credits_carbon_reduction.htm
