10. • Buy "Energy Star" labeled desktops monitors, laptops,
and printers.

11. • Put laptops in "sleep" mode when not in use.

12. • Turn OFF computers and other equipment when not
in use.

13. • E-cycling is generally practiced to reduce the amount
of electronic components that are discarded when
users purchase new components.

14. • Buy the new "Smart Strip" power strip.
• The Smart Strip actually senses how much power
your computer peripherals use.

15. • Print smart or don’t print at all. Don’t waste papers.
• Use E-Mail services and File sharing technology for
Communication.

16. • Proper use of the system devices like the monitors.
• Instead of using the CRT monitor you can adapt the
LCD.

17. • Electronic Waste:
 Use the campus network where
possible to transfer files.
 Use USB memory sticks instead
of CDs, DVDs, or floppies.
Use re-writable CDs and DVDs.

18. • Green business opportunities provide consumers with
ecologically sound products and services.
• The greenest computer will not miraculously fall
from the sky one day; it’ll be the product of years of
improvements.
