Disable screen saver. Don’t print unless necessary and you are ready Use LCDs instead of CRTs as they are more power efficient Slide 16: Use hardware/software with the Energy Star label Energy Star is a “seal of approval” by the Energy Star organization of the government (the EPA) Slide 17: Set low power “sleep” mode - can still download and perform other routines There are two basic options for putting your laptop to sleep when you're not actively using it, but don't want to completely shut it down—Standby or Hibernate. Standby : Standby Standby is energy conserving, because your entire computer switches to a low-power state. Devices, such as the monitor and hard disks, turn off and your computer uses less power HIBERNATE : HIBERNATE Hibernate mode writes an image of what you're currently working on to a special file on your hard drive, and then shuts your computer almost completely off E-MAIL : E-MAIL Use e-mail to reduce paper work. Add: *Please consider the environment : Do you really need to print this e-mail? Put entire message in subject line(“eom”). On-Line : On-Line Increase use of Internet and your Website. Place information on Web pages, wikis, blogs instead of making paper copies. Online courses consume nearly 90% less energy and produce 85% fewer CO2 emissions Slide 24: Printing Savings One More Solution: Recycling : One More Solution: Recycling If companies can recycle the plastics and other components, this can greatly reduce waste and toxins Developed countries now have facilities for recycling e-waste How Do the Companies Rate? : How Do the Companies Rate? 8: Nokia - regained its top position for eliminating the worst chemicals from many products still needs to report on its recycling rate percentage 7.3: Dell - still among the top but loses points for not having models free of the worst chemicals strong support for global take back 7.3: Lenovo - dropping down the rank for not having a clear global take back program still missing out on products free of the worst chemicals on the market 7: Sony Ericsson - among the top with clear timeline to have products free of the worst chemicals by 2008 need better chemicals take back reporting program FINAL QUESTION : FINAL QUESTION When do you need to start walking the talk on green computing? A. As soon as u get back to work B. Tomorrow C. Next Monday D. Today E. Not sure When do you need to start walking the talk on green computing? A. As soon as u get back to work B. Tomorrow C. Next Monday D. Today E.
