3. GREEN COMPUTING
Green computing can be defined as environmentally
responsible use of computers and their resources.
Such practice includes designing manufacturing, using
and disposing of computer server s and its subsystems
with no impact on the environment .

4. NEED FOR GREEN COMPUTING
 Today almost all the streams uses computers which
requires large amount of power for its effective
functioning.
The increase in the use of computers also increases power
consumption and generate a greater amount of heat.
There are toxic chemicals used in the manufacturing of
computers , those chemicals cause ill effect on
environment during its disposal.
To decrease these impacts the term green computing
comes into existence.

5. APPROACHES TO reduce power consumption via GREEN
COMPUTING
Green Data Center
Virtualization
Cloud Computing

6. Green Data Center
 A large group of networked computer servers typically
used by organizations for the remote storage,
processing, or distribution of large amounts of data is
called data center.
 A green data center is a data center which has effective
& efficient management .
 The mechanical, electrical and computer systems are
designed for maximum energy efficiency and
minimum environmental impact.

7. Virtualization
 Virtualization is the
creation of a virtual
(rather than actual)
version of something,
such as an operating
system, a server, a
storage device or
network resources.

8.  Telecommuting, e-commuting, e-work, working at
(/from) home (WAH, WFH) are some of the
examples of virtualization.
 Voice over Internet Protocol (VoIP) facilitates
virtualization. It is just the delivery of voice
communications over the Internet or other packet-
switched networks.
 Voice over IP (VoIP) reduces the telephony wiring
infrastructure , thus reduce the use of metallic
waste.

9. Cloud Computing
Cloud computing delivers the computing resources as
a service over the internet.
User can use the cloud services or cloud application
through a web browser or a mobile app while the
software and user’s data is stored on remote data
server.
Cloud computing allows companies to avoid high cost
on infrastructure and maintenance for storage.

11. BlACKLE
Blackle is a search-engine site powered by Google
Search.
The principle behind Blackle is based on the fact that
the display of different colors consumes different
amounts of energy on computer monitors.
When a computer screen is white it consumes 74W.
When the screen is black it consumes only 59W.
If everyone switched from Google to Blackle, mother
earth would save750MW each year.

13. Zonbu Computer
The Zonbu is a new, very energy efficient PC.
The Zonbu consumes just one third of the power
of a typical light bulb.
 The device runs the Linux operating system using
1.2 GHz processor and 512 meg of RAM. It contains
no moving parts, and does even contain a fan.

15. Ideas to adopt green computing
 The computer shouldn’t be left running overnight.
 The brightness level of monitor can be reduced
while working for long time. It saves energy and
increases monitor longevity.
 The monitor should be turned OFF when its not in
use. The best screen saver is no screen saver at all.
 The power management features in your
computers are enabled.

16.  The monitor is bought only of required size . A large
monitor might seem more attractive , but it
consumes more power than the smaller one. A 17-
inch monitor uses 40 percent more energy than a 14-
inch monitor. Also, the higher the resolution, the
more energy it needs.
 Printers consume energy even while they are idling.
So printers should not be turned ON until you are
ready to print.
 The "paperless" methods of communication such as
email and fax-modems should be used.

17.  Copies of email should not be taken unless
necessary.
 The document should be reviewed on the screen
instead of printing it.
 Non-petroleum-based inks can be used. These
printer inks are made from renewable resources;
require fewer hazardous solvents; and in many
cases produce brighter, cleaner colors.

18. Conclusion
 Green computing developments can enable individuals
and businesses to adopt greener lifestyles and work
styles .
 Apart from ecological issues, this is also beneficial on
economic view.
 Going green is very much important to make ourselves,
our surroundings and the planet healthy.
