3. Green Computing can be described as
the environmentally responsible usage of
computer systems and related resources.

4. Contd…….
It is also known as the study
& practice of manufacturing, using &
disposing of computers, servers &
associated subsystems efficiently &
effectively.

5. ORIGIN
In 1992,the U.S Environmental Protection
Agency launched “Energy Star”,a labeling
programm designed to promote & recognize
energy efficiency in monitors, climate control
equipments and other technologies.
The term GREEN Computing was coined shortly
after energy star programme.

6. Contd…
….
Concurrently, the Swedish organization TCO
Development launched the TCO certification program
to promote low magnetic and electrical emissions
from CRT-based COMPUTER DISPLAYS.
The energy star program was revised in October
2006 to include stricter efficiency requirements for
computer equipment, along with a tiered ranking
system for approved products.

7. 1.The main reason is the growing
of public environmental
awareness.
2.To reduce energy wastage.
3.It helps to save a lot of
money.

8. 4.To reduce power consumption.
5.To reduce impacts on environmental &
human health. The main aim is to reduce
the amount of carbon emissions.

9. 6.To avoid toxicity.
Lead:-can cause damage to the central &
peripheral nervous system.
Mercury:-can cause chronic brain damages.
Cadmium:-accumulate in the human body
specially the kidney.
7.To reduce IT maintenance activities.
8.To reduce the paper & other
consumables used.
9.A corporate social responsibility.
10.A step for need of tomorrows future.

10. E-Waste Definition
• Any discarded electronic or electrical devices or
their parts; also called electronic waste
• Examples: Computers, LCD / CRT screens,
cooling appliances, mobile phones, etc., contain
precious metals, flame retarded plastics, CFC
foams and many other substances.

11. METHODS OF
DISTROYING WASTE
Hazardous Technologies Recycling Technologies
Open Burning
Land filling 1. Detoxication
2. Refining
3. Shredding

12. MercuryLead
Arsenic Polychlorinated
Biphenyls
(PCBs)Toner
Some Hazardous Components of
E-Waste and Effects on Humans

13. •Renal Toxicity
•Anemia
•Colic
•Insomnia
•Seizures
•Coma In Children
•Renal toxicity
•Muscle tumors
•Mental retardation
•Cerebral palsy

14. •Cancer Of Skin
•Lungs
•Liver
•Respiratory Tract
Irritation
•Suppression Of Immune
System
•Damage To The Liver
• Nervous
•Reproductive Systems

16. Disadvantages of Green Computing
• High startup cost
• Not readily available
• Still in Experimental stage
• Not for everyone
• High maintenance cost

17. 1. Buy "Energy Star" labeled monitors,
desktops, laptops, and printers
2. Put laptops in "sleep" mode or
“Hibernate” mode when not in use
Pathways to
green computing

18. 3. Turn OFF computers and other
equipments when not in use
4. E-cycle used computer equipments
5. Buy the new “Smart Strip” power strip
6.Set “Blackle” as your homepage

19. 7. Use LCDs instead of CRTs as they are more
power efficient
- CRT uses 150 Watts
8 hours of usage, 5 days a week=562KWatts
If the computer is left on all the time, without proper power
saver modes, this can leads to 1,600KWatts.
8. Buy Green products

21. E-Waste Management
• Sri Lankan Government has been initiated
e-waste collecting centers.
• Ceylon Waste Management and their
Material Refining Process .
Sri Lankan Approach of Green Compu

22. Companies and Organizations
• Most of Sri Lankan Companies and Organizations
already have took the first step to Green Computing.

23. • Following Standards for minimizing health effects
and environmental effects.
Following Standards

24. Future of Green Computing
“ The plan towards green IT should include new
electronic products and services with optimum
efficiency and all possible options towards
energy savings “
The future of Green Computing will be
full of …
• Virtualization
• Energy Saving
• Eco Friendly Materials
• Recycling
And etc.

25. Virtualization
Virtualization, in simple terms, is moving
physical servers to virtual ones.
What is Virtualization ?
Why is it important?
Few of the most important features of virtualization is that it…
Saves money
Saves energy
Reduce e-waste

26. Technologies used for Virtualization
Microsoft Virtual Server VMware
Future of
Virtualization
VMware’s Virtualization Progress
Did you know ?
50-60% of all servers are now virtualized

27. Natural Cooling Systems
Smart Plug
Solar Systems
Eco-Friendly mobile
chargers
Energy Saving

28. Eco Friendly Materials
Mercury-free backlighting
and arsenic-free glass
in displays
Not using Lead, Chromium Mercury
and other toxic chemicals for
manufacturing computer devices
Using recyclable or digital newspapers

29. Recycling
In future, almost all the computer devices and
items will be able to be recycled
Recyclable PCBs
Recyclable Batteries
Take-back
concept of the
manufactures

30. That’s all about the future
of Green Computing
It’s not easy not being green
So, Let’s Go Green!
