2. In 1992, the US Environmental Protection
Agency launched Energy Star to promote and
recognize energy efficiency in monitors, climate
control equipment, and other technologies.
Energy Star : International
standard for energy-efficient
electronic equipment.
“Green computing" was coined shortly after
the Energy Star program began.

3. Energy costs and electrical requirements of IT industry
around the world show a continuously growing trend.
For example , ICT industry is responsible for 3% of
the world‘s energy consumption. With the
rate of consumption increasingly by 20%
a year,2030 will be the year when
the world‘s energy consumption will double
because of the ICT industry.
NEED FOR GREEN COMPUTING

4. Green computing: “Future of Computers”
The Green Computing Initiative, stewards of the industry
standards EFGCD ( Eco Friendly Green Computing
Definition).
Eco- Friendly Green Computing is the study and practice
of the design, development, implementation, utilization
and disposal of IT infrastructure efficiently and effectively
with low or zero impact on the environment whilst
reducing operating costs.
It includes implementation of energy-efficient central
processing units (CPUs), Servers and Peripherals as well as
reduced resource consumption and proper disposal of
electronic waste (e-waste).

5. OBJECTIVES OF GREEN COMPUTING:
To gain an understanding why the green computing
is instrumental for the environment.
To identify key issues relevant to green computing
and evaluate different approaches to these
problems.
To make use of computers as energy-efficient and
design algorithms and systems for efficiency-related
computer technologies.

6. Five Steps to Green Computing:
Develop a sustainable green computing plan.
A plan should include recycling policies,
recommendations for disposal of used equipment,
government guidelines and recommendations for
purchasing green computer equipment.
Recycle.
Discard used or unwanted electronic equipment in a
convenient and environmentally responsible manner.

7. Make environmentally sound purchase decisions.
Purchase Electronic Product Environmental Assessment Tool
registered products. EPEAT is a procurement tool promoted by
the nonprofit Green Electronics Council.
Reduce Paper Consumption.
Use e-mail, electronic archiving.
Use the “track changes” feature in electronic documents
Conserve energy.
Power management tactics can save energy and help
protect the environment.

8. Green computing represents a responsible way
to address the issue of global warming. By
adopting green computing practices, business
leaders can contribute positively to
environmental stewardship and protect the
environment while also reducing energy and
paper costs.
Sustaining the Future

9. Some points to remember:
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 unless required.
Purchase LCD‘s monitors which consume less energy than CRT‘s
screen and LCD‘s is also not harmful for the eyes.
Mobile phones are better than computers – green computing. They
have faster processors, more ram, faster wireless Internet
connectivity and larger memories. Mobile Phones consume
very low power.

10. CONCLUSION
Green computing is a mindset that asks how we can
satisfy the growing demand for network computing
without putting such pressure on the environment.
By adopting green computing practices, business leaders
can contribute positively to environmental
stewardship—and protect the environment while
also reducing energy and paper costs.
