5. Green IT
The study and practice of using computing
resources in an efficient, effective and
economic way.

6. An Important Fact

7. An Important Fact
(By David Tebbutt,Martin Atherton, and Tony Lock)
…of Global CO2
Emissions

8. • Datacentres produce 0.3% of world’s CO2
• If designated as a country, datacentres would be 76th on
co2 emission list
• Datacentres also consume 0.8% of the world’s electricity

9. GREEN IS EVERYWHERE
68% Of Executives foresee increased
government regulation on
environment
77% Of Companies anticipate
spending more on Environmental
Programs.
80% of all data centers report
capacity issues
83% Of Largest Retailers are
involved in Green Practices.

10. Actual Amount of Energy
Used

11. Problems
 Rising energy prices are increasingly impacting
on the cost of doing business
 Government imposed levies on carbon
production will impact all businesses with
businesses increasingly judged according to
their environmental credentials, by legislators,
customers and shareholders.

12. Approaches to Green IT
 Virtualization
 Power management
 Material recycling
 Telecommuting

13.  A study by McKinsey found that among
observed 458 servers at 4 datacentres 32%
were running at or below 3% peak utilization
 Virtualization helps reduce server counts by as
much as 65%

14. Virtualisation
 The process of running two or more logical
computer systems on one set of hardware.

15. Contd…
 Virtualization helps a company / enterprise
lower power and cooling consumption, by
reducing the number of machines and servers
it needs
 Virtualization platforms can run across
hundreds of interconnected physical
computers and storage devices, to create an
entire virtual infrastructure

16. Power Management
 Power Supply
 Storage
 Display

17. Material Recycling
 HR233, the U.S. National Computer Recycling
Act
 e-Waste handling

19. Telecommuting
 Teleconferencing and telepresence technology
 Web meetings and webinars, where people can
share content and interact with each other
through their webcams and PC screens.
 Working at home

21. Green Data Center
 Repository for the storage, management, and
dissemination of data
 Mechanical, lighting, electrical and computer
systems designed for maximum energy
efficiency and minimum environmental impact

22. Green Data Center

23. Implementation of GDC
 The construction and operation of a green data
center includes advanced technologies and
strategies
 Here are some examples:
 Minimizing the footprints of the buildings
 Use of low-emission building materials, carpets and
paints
 Sustainable landscaping
 Waste recycling
 Installation of catalytic converters on backup
generators
 Use of alternative energy technologies – eg.
photovoltaics

24. Advantages of GDC
 Can be expensive up front, but long-term cost
savings can be realized on operations and
maintenance
 Offers employees a healthy, comfortable work
environment
 Green facilities enhance relations with local
communities
 Easier to comply with regulations, if imposed
 Elimination of utility shortfall

25. Green IT trends in India
 Seriously concerned about being environmentally-savvy
 But few companies are ready to walk the talk
 Only 27.2% of Indian businesses have implemented
power-saving technologies like hot aisle or cold aisle
containment
 77% IT companies here feel power shortage in India will
soon affect them
 Companies planning to spend on energy-efficient servers
(for 54% of surveyed Indian businesses) and server
virtualization (41%)

26. Green data center design at
Wipro Infotech
 New ‘Tier-III’ data center at Greater Noida with
replicable green data center model
 Extensive planning before selecting data centre
solution
 Power and cooling identified as the primary areas
for green technology deployment
 Reduce electrical losses
 Optimize cooling
 60-70% times company recover cost within 4 yrs

27. Recommendations

28. Online
Dr. John Thompson – Blueprint for Green Computing eSeminar
 Increase use of the Internet and your Web site
 Place information on Web pages, wikis and blogs
instead of making paper copies
 Online courses consume nearly 90% less
energy & produce 85% fewer CO2 emissions –
2005 report
 Uses less paper than traditional classroom
 Ex. - Online course evals instead of paper
 Assign online texts or Internet sites
 Use course management systems
 Ex. - Blackboard, ANGEL

29. Final Recommendations
 Pick all the low hanging fruit
 Small changes make big difference
 Conduct energy assessment
 Set baseline…& measure, measure, measure
 Strive to achieve TBL – triple bottom line
 Economic
 Environmental
 Social
Save $$ while helping
protect the environment and
doing what’s right for society.
