CLOUD IS GETTING GREEN
ABSTRACT: Cloud computing is revealing as a critical
information communication
technology to heavily affect our daily life in
the future. but usage of
cloud computing, either private or public, can usher to uneconomical energy
consumption in data processing, storage and communication. Hence, green cloud
computing solutions aim not only to save energy but also reduce operational
costs and carbon footprints on the environment.
Green computing is the environmentally sustainable to use of computers
and related resources like - monitors, printer, storage devices, networking and
communication systems - efficiently and effectively with minimal or no impact
on the environment. Its goals are to
reduce the use of hazardous materials, maximize energy efficiency during the
product's lifetime, and promote the recyclability or biodegradability of
defunct products and factory waste. Computers today not only used in offices
but also at homes. As the number of computers is increasing day by day, so is
the amount of electricity consumed by them which in turn is increasing the
carbon content in atmosphere. This problem has been realized by people and
measures are being taken which help in minimizing the power usage of computers.
Therefore , this can be called as Green Computing. We use Green Computing as it-
reduced energy usage from green computing techniques translates into lower
carbon dioxide emissions, stemming from a reduction in the fossil fuel used in
power plants and transportation, Conserving resources means less energy is
required to produce, use, and dispose of products ,Saving energy and resources
saves money .also includes changing government policy to encourage recycling
and lowering energy use by individuals and businesses.

INTRODUCTION:
Most developing countries face
financial, geographical, infrastructure, and power curbs that have largely
forbid development of reliable
communications networks,data centers,
and local ICT-related activity—all of which could be contributing to
socio-economic growth and development. This situation is particularly
unfortunate since appearing economies stand to gain a great deal from the
benefits associated with telecommunications and related ICT advances
that make distance outdated.
Why Computing Green
Today almost all areas like IT, medicine,
transportation, agriculture uses machines which indirectly requires large
amount of power and money for its effective working. We have great machines and
equipments to attaining our chore, great gadgets with princely looks and
features make our lives more impressive and smooth. Green computing whose goals
are to reduce the use of hazardous materials, maximize energy efficiency during
the product's lifetime, and promote the recyclability or biodegradability of
defunct products and factory waste.
. Tackle towords the Green Computing
Data centers, which have been criticized for their
extraordinarily high energy demand, are a primary focus for proponents of green
computing. Data centers can potentially improve their energy and space efficiency
through techniques such as storage consolidation and virtualization. Many
organizations are starting to eliminate underutilized servers, which results in
lower energy usage. The U.S. federal government has set a minimum 10% reduction
target for data center energy usage by 2011. With the aid of a self-styled
ultraefficient evaporative cooling technology, Google Inc. has been able to
reduce its energy consumption to 50% of that of the industry average.
Enactment of green Computing:
Blackle: Blackle
saves energy because the screen is predominantly balck. “Image displayed is
primarily a function of the user’s color settings and destop graphics, as well
as the color and the size of open application windows; a given monitor requires
more power to display a white ( or light) screen than a black (or dark) screen.
In
January 2007 a blog post titled Black Google would save 750 Megawatt-hours a
Year proposed the theory that a black version of the Google search engine would
save a fair bit of energy due to the popularity of the search engine.
In
2014 the majority of monitor sales are LED backlit LCD’s which do not light up
the parts of the screen that are black. Some older CCFL LCD monitors worked by
wastefully backlighting the entire screen. Since 2005 manufacturers have moved
away from CCFL’s
We
believe that there is value in the concept because even if the energy savings
are small,they all add up. Secondly we feel that seeing Blackle every time we
load our web browser reminds us that we need to keep taking small steps to save
energy.
The idea behind
Blackle is that computer monitors
can be made to use less energy by showing much darker colors. Blackle is based
on a study which tested a variety of CRT
and LCD monitors. There is
dispute over whether there really are any energy saving effects, especially for
users of LCD screens, where there is a constant backlight
This concept was
first brought to the attention of Heap Media by a blog post, which estimated that Google
could save 750 megawatt hours a year by utilizing it for CRT screens.The homepage of Blackle provides
a count of the number of watt hours claimed to have been saved by enabling this
concept.
CONCLUSION:
By simply improving the efficiency of
equipment, Cloud computing cannot be asserted to be Green. What is important is
to make its usage more carbon efficient both from user and provider‟s panorama.
Cloud Providers need to lessen the electricity demand of Clouds and take major
steps in using renewable energy sources rather than just looking for cost
minimization.
