The document discusses green computing, which focuses on the environmentally responsible use of computers and their resources. It outlines the need for green computing due to rising power consumption, heat generation, and toxic disposal from computers, and presents approaches such as green data centers, virtualization, and cloud computing to reduce energy usage. Additionally, it highlights examples like Blackle and the Zonbu computer, along with practical ideas for adopting green computing practices to promote ecological and economic benefits.

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.
