• Solutions
• Approaches
• Ways to be the Green
• Green Web Surfing
• Conclusion

3. What is
Green IT ?
Developed
Delivered
Used

4. Why
Green IT ?
• Pollution
• Toxicity
• Increased energy usage

5. Pollution
•Manufacturing Techniques
•lead, tin, copper, silicon, carbon,
iron,aluminum
Mercury, Plastics…..
•Disposal of computers and
components (E waste)
•Disposal of these devices constituted
20-50 million tons per year (about 5% of
the total waste of the planet)

6. Energy Use of PCs
• Energy use comes from
– Electrical current to run the
CPU, motherboard, memory
– Running the fan and spinning the
disk(s)
– Monitor (CRTs consume more power
than any other computer component)
– Printers
– Servers
• Energy also required to run the
applications,database etc..
• CPU uses 120 Watts
• CRT uses 150 Watts

7. Energy Use In The Data Centre
• Consume 10 to 100 times more
energy per square foot
than a typical office building
• Used about 45 billion kWh
in 2005
• At current rates, power
requirements could Triple
in 8 years.

8. Solutions
• Reuse: Donate your computer
components to people who may not
have or have lesser quality computers
• Refurbish: Rather than discarding
your computer when the next
generation is released, just get a new
CPU and memory chips – upgrade
rather than replace
• Recycling: If companies can recycle
the plastics and other components,
this can greatly reduce waste and
toxins.

9. 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 or 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

10. Ratings of companies(cont….)
6.7: Samsung - strong position for having a good
chemical policy, but still lack products that are free
from the worst chemicals
its take back system is not yet global and need improvement
6.7: Motorola - some products on the market are free
from the worst chemicals but loses points for not
providing clear timelines for eliminating these
chemicals in all products
score points on reporting the recycling rate
6: Toshiba - good improvement particularly on waste
and take back criteria
moved forward for providing some models without the worst
chemicals and for timelines for complete phase out
5.7: Acer - standing still with improved chemical
policies but no models free of the worst chemicals
needs to improve on take back program
5.3: Apple - top mover with concrete timelines to
eliminate the worst chemicalloses points for not have a
green product on the market and for a weak take back
programs

11. Approaches to GREEN
COMPUTING
•Virtulization: Virtualization is a key strategy to
reduce data center power consumption With
virtualization; one physical server hosts
multiple virtual servers
•Power Management
•Reduce noise
•Reduce cooling requirements
•Reduce operating costs for energy and cooling
•Materials Recycling:This can include finding
another use for the system (i. e. donated to
charity).

12. Way to be the
Green ?
With existing technology…
• Turn off the computer when not
in use, even if just for an hour
• Turn off the monitor when not in
use (as opposed to running a
screen saver)
• Use power saver mode.
• Don’t print unnecessary thing
like mails.
• Use LCDs instead of CRTs as
they are more power efficient

13. Way to be the
Green (cont…)
When purchasing new
equipment…
• Use hardware/software with the
Energy Star label
– Energy Star is a “seal of approval” by
the Energy Star organization of the
government.
• Buying multi-functional
equipment.

14. Green Web Surfing

15. Conclusion
• Manufacturer’s today aim to improve
energy efficiency by creating designs that
minimize power waste and reduce
emissions
• Devices use less and less power while
renewable energy gets more and more
portable and effective.
• New green materials are developed every
year, and many toxic ones are already being
replaced by them.
• The features of a green computer of
tomorrow would be like: efficiency,
manufacturing & materials, recyclability,
service model, self-powering, and other
trends
