3. Do you Know ???
Computers have a negative impact to our
environment

4. Cause pollutions
• and computer monitors are responsible
for the unnecessary production of millions of
tons of greenhouse gases every year.
Pollution
4

5. E-Waste
Technology
creates large
amounts of
waste, and used
computers and
electronics get
thrown out
when they break
or become
outdated. 5

6. Produce green house gases
6

7. • Greenhouse gasses are gasses in the
atmosphere that trap and reflect heat and
radiation back to the planet's surface.
• Green gasses are contributing to globe
warming.

8. Cause pollutions

9. Cause pollutions
• Air, water, heat and noise pollution can all be
caused by producing and using technology

10. Waste
• Manufacturing technology creates large
amounts of waste, and used computers and
electronics get thrown out when they break or
become outdated.

11. Produce green house gases

12. So, how can prevent this!!!
Using green computing can prevent
this…
• Cause pollutions
• Produce waste
• Produce green house gases

13. What is Green computing
• Designing, manufacturing, using and disposing
of computers, servers and associated sub
systems efficiently an effectively with minimal
or no impact on the environment.

14. Paths to
Green computing
Green use
Green Disposal
Green design
Green Manufacture

15. Things we can do…
1. Buy energy efficient computers
2. Buy hardware appropriate for the job
For example a 19’’ monitor use 40% more power
than a 17’’ monitor.

16. Things we can do…
3. Replace CRT monitor with an LCD monitor.
LCD monitors can use one-half to two thirds the
energy of a CRT monitor, Flat screen monitors
also result in less eye-strain

17. Things we can do…
4. Turn off computer when it will not be using
for several hours.

18. Thing we can do…
5. Print smarter
Use the electronic print preview to avoid wasted
paper.
Print double sides.
Print draft copies when appropriate.
these use less ink and are still readable.

19. Things we can do…
6. Enable power management features on
computer
Setting the hibernation or sleep modes to place
the computer on low power after a given period
of inactivity

20. Things we can do…
7. Recycle old computers
When no longer are able to find a use for
computer, consider to recycle PC properly.

21. Things we can do…
8. Virtualization
Process of running two or more logical computer
systems on one set of physical hardware.

22. Things we can do…
9. Energy Efficient Coding
Energy efficient coding could reduce the energy
consumption by 25% to 30%.
Improving computational efficiency so that data
is processed as quickly as possible and the
processor can go into lower power idle state.

23. Green Web Surfing

24. • Search-engine site powered by Google Search.
• White consumes 74W whereas black it consumes
only 59W.

25. Zonbu Computer
• New & energy efficient PC.
• Runs the Linux OS using
1.2GH processor & 512MH
of RAM.
• Consumes one third of the
power of a typical light bulb.

26. FIT-PC
• Size of a paperback
& Silent, run
WindowsXP or Linux.
• Draws only 5 Watts
than PC.

27. Sunray Thin Client
• Consume less
electricity than
conventional
desktops.
• Consumes 4 to 8
watts of power.

28. ASUS Eee PC
• Is one example of an
ultraportable.
• Small Size
• Compact Screen
• Low Cost
• Fairly low-power CPU
• Uses flash memory for storage

29. Top Green IT Companies
1. HP
Programs to reduce GHG and Toxic wastes in
their products and supply chains.
2. Dell
Carbon Neutral, Headquarters
uses 100% Renewable
energy, computer products
use 25% less power (by 2010).

30. Top green IT Companies
3. Intel
focus is on increasing speed while
reducing energy usage in their products.
4. IBM
Has had formal Environmental policies since
1971, and requires all employees to have
environmental awareness training.

31. Top Green IT Companies
5. Toshiba (5.3)
Good score on toxics elimination.
6. Apple (5.1)
Continues to improve with best score on toxic
chemical elimination and e-waste criteria.
7. Sony (5.1)
better energy totals.

32. Top Green IT Companies
8. Acer (4.5)
Acer is lobbying for stronger chemical
legislation.
9. Lenovo (2.5)
Penalty point for indefinite phase out of toxics.
10. Microsoft (2.4)
Fails to support strong chemicals legislation.

33. Conclusion
• Green computing is the scientific study of efficient and effective designing,
manufacturing, using, disposing, and recycling of computers.
• The greenest computer will not amazingly fall from the sky one day, it’ll be the
product of the years of improvements. The features of a green computer of
tomorrow would be like
1. efficiency
2. manufacturing and materials
3. recyclability
4. service model
5. self-powering
6. other trends

34. • Adopting green computing strategies make sense not only from an
ethical or moral stand-point , but from a commercial stand-point.
• There are many business benefits achievable through the
implementation of a green computing strategy such as cost savings,
disaster recovery and course public relations.
• Green computing is the great requirement to protect environment
and save energy along with operational expenses in today’s
increasingly competitive world.
