Abstract— while searching for information about cloud computing over the internet, I came across a computing keyword that is
Green Computing. After so much of research on this term I myself tried to have the clear vision about it. This paper will help the
researchers and administrators to have a clear understanding of Green Computing. In this modern era of globalization,
computers play a vital role in every field, so the needs of computers increased day by day and, to full fill this need, a large
amount of electricity required for manufacturing of computers functional units, such as CPU, memory, monitors and peripheral
devices etc. By this a large amount of carbon content consumes in the atmosphere. These carbon contents directly or indirectly
impact us and responsible for hazards on the earth. However, the growing demand of Cloud infrastructure has drastically
increased the energy consumption of data centres, which has become a critical issue. High energy consumption not only
translates to high operational cost, which reduces the profit margin of Cloud providers, but also leads to high carbon emissions
which is not environmentally friendly. There are many technique used by intelligent people to overcome this problem, one of that
technique is Green computing. Green Computing takes responsibility of eco-friendly use of computer and their resources. In
order to design such solutions, deep analysis of Cloud is required with respect to their power efficiency. Mainly, IT industries are
responsible for 3% of the world’s energy consumption with an increase of 20% per year. The main goal of Green computing is to
increase the efficiency of the IT products during its lifecycle and endorse the recycling of useless goods and factory waste. This
paper introduces some energy efficient techniques of green computing and their use in future.

1 INTRODUCTION

HIS Cloud computing is a style of computing in which
dynamically scalable and often virtualized resources are
provided as a service over the Internet. A number of advantages of cloud computing for the enterprise have been recognized. Among these are improved TCO, reduced infrastructure costs, improved business agility, converting fixed costs to
variable costs, and of course, with respect to power, acquiring
IT services which can be scaled as needed, even on a temporary basis to deal with peaks in IT requirements, and which do
not impose power capacity constraints. Although enterprises
have been hesitant thus far to adopt cloud computing broadly
as a source of IT services, there are cases where cloud
computing might be advantageous, without raising the typical concerns about security, reliability, meeting SLAs, and other issues raised by cloud computing which have not yet been
fully resolved. Suggests that there are four cases where the
cloud should be considered by CIOs, namely, for: (1) new initiatives where budgets are very constricted; (2) business
processes which have widely varying or unpredictable load
patterns; (3) services provided by non-core systems which
are commoditized; and (4) systems where infrastructure management and operations costs are high.
A study by environmental campaign group Global Action
Plan into Green Cloud Computing found that IT infrastructure
accounts for 10% of the UK's annual energy consumption. This
results in the same amount of CO2 emissions given off by airplanes. We should be committed to reducing CO2 footprint
and by innovating the organizations with Green Cloud Computing we can play a considerable role in lessening the impact
of your computing on the environment. Green Computing is
the emerging technology which is responsible for the manufacturing and use of computer devices by consuming less
carbon.
The increasing availability of high-speed Internet and corporate IP connections is enabling the delivery of new networkbased services. While Internet-based mail services have been
operating for many years, service offerings have recently expanded to include network-based storage and network-based
computing. These new services are being offered both to corporate and individual end users. Services of this type have
been generically called cloud computing [services]. The cloud
computing service model involves the provision, by a service
provider, of large pools of high performance computing resources and high-capacity storage devices that are shared
among end users as required. There are many cloud service
models, but generally, end users subscribing to the service
have their data hosted by the service, and have computing
resources allocated on demand from the pool. The service
provider’s offering may also extend to the software applications required by the end user. To be successful, the cloud service model also requires a high-speed network to provide
connection between the end user and the service provider’s
infrastructure. Cloud computing potentially offers an overall
financial benefit, in that end users share a large, centrally managed pool of storage and computing resources, rather than
owning and managing their own systems. Often using existing
data Centre’s as a basis, cloud service providers invest in the
necessary infrastructure and management. Many computers
are produced from many hazardous materials like cadmium,
mercury and other toxic substances. While disposing the com-

puters, it will lead to pollution and affect the environment to
great extent. The impact of the toxic waste that is produced by
us through throwing our old computers and peripherals lead
to land pollution .This is the big challenge, how to minimize
the power consumption and thereby reducing the carbon content in the atmosphere. The goal of green computing is to reduce the use of hazardous materials, maximize energy efficiency during the product’s lifetime, and promote recycle ability. Green Computing is the name attached to this movement,
which represents an environmentally responsible way to reduce power and environmental e-waste. Many IT manufactures and vendors are continuously investigating in designing
energy efficient computing devices, reducing the use of dangerous materials and encouraging the recyclability of digital
devices and paper. Its practice came in to being in 1992, when
the Environmental Protection Agency (EPA) launched the
Energy Star Program. EPA a voluntary labelling program
that is designed to promote and recognize energy efficiency in
monitors, climate control equipment and other technologies.
Green technology comprises of the study of advanced materials to be used in everyday life and the study of new generation techniques. The main topic of concern in green technology
is to reduce the environmental impact of industrial processes
along with the growth in population resulting in innovative
technologies. Basically, the efficient use of computers and
computing is what green computing is all about. The triple
bottom line is what is important when it comes to anything
green and the same goes for green computing. This considers
social responsibility, economic viability and the impact on the
environment. The huge amount of computing manufactured
worldwide has a direct impact on environment issues, and
scientists are conducting numerous studies in order to reduce
the negative impact of computing technology on our natural
resources. A central point of research is testing and applying
alternative non-hazardous materials in the products’ manufacturing process. The idea is to make computers from beginning
to end a green product.
Green computing is the environmentally responsible and eco-friendly use of computers and
their resources. In broader terms, it is also defined as the study
of designing, manufacturing/engineering, using and disposing of computing devices in a way that reduces their environmental impact.
Many IT manufacturers and vendors are
continuously investing in designing energy efficient computing devices, reducing the use of dangerous materials and encouraging the recyclability of digital devices and paper. Green
computing is also known as green information technology
(green IT).
Green computing, or green IT, aims to attain economic viability and improve the way computing devices are used. Green IT
practices include the development of environmentally sustainable production practices, energy efficient computers and
improved disposal and recycling procedures. The term ‘Green
Computing’ is the study and practices of designing IT equipment and their safe disposal efficiently and effectively with
negligible or no impact on the environment. It has two factors
“Green-IT” means well organized IT and “IT-for Green”
means use of IT in an efficient way. First and most conclusive
research on computing shows that Carbon Dioxide (Co2) and
other emissions are causing global climate and environmental
112
damage. Thus go green is the first and foremost need of modern age that can decrease the overall energy consumption of
computation, storage and communications. The 5 core green
computing technologies advocated by GCI are Green Data
Centre, Virtualization, Cloud Computing, Power Optimization
and Grid Computing. Company like Via Technology offer
green PC‘s that are affordable, non- toxic and ultra-low wattage. It takes responsibility of their outdated products by offering a PC recycling service. Green computing can also develop solutions that offer benefits by "aligning all IT processes
and practices with the core principles of sustainability, which
are to reduce, reuse, and recycle; and finding innovative ways
to use IT in business processes to deliver sustainability benefits across the enterprise and beyond".
The goals of green computing are quite similar to green chemistry which are to reduce the use of hazardous materials,
maximize energy efficiency during the product's lifetime, and
promote the recyclability or biodegradability of nonoperational products and factory waste.
This technology is beneficial as it:- a) Reduce energy consumption of computing resources during peak operation. b)
Save energy during idle operation. c) Use eco-friendly sources
of energy. d) Reduce harmful effects of computing resources.
e) Reduce computing wastes.
2 NEED OF GREEN CLOUD COMPUTING
IJSER
Use of computer system and IT services had made one’s life
easier and more comfortable. It increases the processing speed
and power consumption also. This large amount of power
consumption increases the emission of greenhouse gases and
increases the pollution as well. Energy consumption is also
increasing due to, leaving the system on even when they are
not being used. Along with this a large amount of energy
wasted in IT, because data centers needed lots of power and
matching cooling capacity, when it is not available then it
causes environmental pollution. Green computing deals with
the concept of reducing energy consumption, recycling eliminate hazardous elements but it also deals with reduce in the
business travel sharing the resources (cloud computing) and
optimization. Insufficient power and cooling capacities can
also results in loss of energy. This all become responsible for
the polluted environment. It also observed that most of the
data centers used old technologies based system and they
don’t have sufficient cooling capacities. This all leads us towards the polluted environment. The environment pollution
could be because of the defects in Manufacturing techniques,
packaging, disposal of computers and components. There are
toxic chemicals used in the manufacturing of computers and
components which can enter the food chain and water. It is
observed from one source, “Information Technology energy
demand is growing Twelve times faster than the overall demand for energy” and Data centers emits 150 metric tons of
CO2 per year, and the volume is increasing rapidly[xc]. In
order to create standards and regulations various organizations have been formed. Some of these organizations are:
1.The Green Grid is a global pool of IT companies and professionals looking for improve energy efficiency in various data
centers around the globe. Board members of the Green Grid

include AMD, EMC, Intel, APC, HP, Microsoft, Dell, IBM, and
Oracle. 2. The U.S. Environmental Agency is a government
agency that was created to protect human health and to safeguard the natural environment. These organizations were
formed to reduce the green gas emission and other pollutants
caused by the inefficient use of energy; and Make it easy for
consumers to from the view of a user in an organization.
There are lots of fundamental steps that can be taken to significantly decrease the power consumption and impact on environment.
i) Energy Consumption: According to environmental protection agency around 30% to 40% of computers are kept ON
during the weekends and even after office hours and around
90% of these computers remain idle. If we develop any application in green computing environment it will use optimal
physical resources.
ii) E-waste recycling: Many developed countries are stronger
in technology hence a huge amount of computer systems and
related products are discarded every day. These products are
sold out to other developing countries. In this way recycling
of electronic products are achieved. Along with this, recycling
of materials used in construction of computer hardware such
as tin, silicon, iron, aluminum etc. and electronic items such as
audio visual components, mobile phones and other handheld
electronic devices contribute a lot in reducing energy efficiency. Recycling of computing equipment such as lead and mercury enables to replace equipment that otherwise would have
been manufactured. The reuse of such equipment allow saving
energy and reducing impact on environment, which can be
due to electronic wastes [2].
iii) Virtualization: With virtualization, a system administrator
could combine several physical systems into virtual machines
on one single server to run multiple operating systems and
make it more powerful. Energy-efficiency can be achieved
with less physical equipment plugged in, which reduces power and consume less electricity. Several commercial companies
and open-source projects now offer software packages to enable a transition to virtual computing.
It is the fact that virtualization alone doesn't maximize energy
and resource efficiencies. So, combined with the right skills
and operational and architectural standards, automation minimizes the need of physical infrastructure which in turn maximizes the energy and resource efficiencies from server virtualization.
iv) Cloud as a Green computing: Businesses are rapidly moving from traditional system to cloud based system because of
its faster scale-up/scale-down capacity, pay-per-use and
access to cloud-based services without buying and managing
on-premises infrastructure. The pay-per-use facility of cloud
infrastructure provides energy and resource efficiencies simultaneously and promote users to consume only those resources
which are required. An IT organization can achieve energyefficiency and sustainability goals by moving the load from
ordinary servers to cloud servers. But unfortunately IT industries are acquiring the 70 percent of their electricity from
greenhouse gas-emitting fossil fuels, like coal and leaving a
significant amount of carbon footprint. If cloud providers
want to make their services as a green, they must invest in
renewable energy sources. This can be achieved by generating
113
power from renewable sources of energy, like wind, solar.
When the screen is black it consumes only 59W.Based on this
theory if everyone switched from Google to Blackle, mother
earth would save750MW each year. This was a really good
implementation of Green Computing.

5 RECENT IMPLEMENTATIONS OF GREEN COMPUTING
i. Blackle: Blackle is a search-engine site powered by Google
Search. Blackle came into being based on the concept that when a
computer screen is white, presenting an empty word or the
Google home, and your computer consumes 74W. When the
screen is black it consumes only 59W.Based on this theory if
everyone switched from Google to Blackle, mother earth would
save750MW each year. This was a really good implementation of
Green Computing. The principle behind Blackle is based on the
fact that the display of different colors consumes different
amounts of energy on computer monitors.

DEGRADATION, POLLUTION, AND ENERGY USAGE.
7. USE NETWORK PRINTER IN A BUSINESS ORGANIZATION TO SAVE
THE PAPER AND ENERGY. BY USING ENERGY STAR QUALIFIED
PRODUCTS HELP A LOT IN ENERGY CONSERVATION.
8. INSTEAD OF USING REGULAR MONITORS ORGANIC LED SHOULD
BE USED.
9. DONATION OF OLD COMPUTERS AND OTHER PERIPHERALS
REDUCES THE RATE OF GENERATION OF E-WASTE WHICH
INTERNS REDUCES ENVIRONMENTAL POLLUTION.
10. USE OF COMPUTERS GREATLY REDUCES THE USE OF PAPERS,
BECAUSE A HUGE AMOUNT OF DATA CAN BE STORED IN HARD
DISK OF COMPUTERS AND AVOIDS THE PLACING RECORD ON
PAPERS.
11 .TO HAVE THE RECORD STORED IN COMPUTERS IN THE FORM OF
PAPERS, PRINTERS CAN BE USED BUT TO REDUCE THE PAPER
WASTE, WE SHOULD THINK 3 TO 4 TIMES BEFORE USING
PRINTERS.
12 .DUE TO RAPID DEVELOPMENT IN IT, THE GAMES WHICH WERE
STORED IN A DISK ARE NOW AVAILABLE ON INTERNET, WHICH
REDUCES THE PROBLEM OF USING DISKS AND BOXES THAT WERE
REQUIRED A LOT OF RESOURCES.
ii. Fit-PC: a tiny PC that draws only 5w: Fit-PC is the size of a
paperback and absolutely silent, yet fit enough to run Windows
XP or Linux. Fit-PC is designed to fit where a standard PC is too
bulky, noisy and power hungry. If you ever wished for a PC to be
compact, quiet and green then fit- PC is the perfect fit for you.
Fit-PC draws only5 Watts, consuming in a day less power than a
traditional PC consumes in 1 hour. You can leave fit-PC to work
24/7 without making a dent in your electric bill.
iii. 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 a1.2
gigahertz processor and 512 Meg of RAM. It also contains no
moving parts, and does even contain a fan. You can get one for as
little as US$99, but it does require you to sign up for a two-year
subscription.
iv. Sunray thin client: Sun Microsystems is reporting increased
customer interest in its Sun Ray, a thin desktop client, as electricity prices climb, according to Subodh Bapat, vice president and
chief engineer in the Eco Responsibility office at Sun. Thin
clients like the Sun Ray consume far less electricity than conventional desktops, he said. A Sun Ray on a desktop consumes 4 to 8
watts of power, because most of the heavy computation is performed by a server. Sun says Sunrays are particularly well suited
for cost-sensitive environments such as call centers, education,
healthcare, service providers, and finance. PCs have more powerful processors as well as hard drives, something thin clients don't
have. Thus, traditional PCs invariably consume a substantially

ISSN 2229-5518
larger amount of power. In the United States, desktops need to
consume 50 watts or less in idle mode to qualify for new stringent Energy Star certification.
v. The Asus Eee PC and other ultra-portables: The "ultraportable"
class of personal computers is characterized by a small size, fairly low power CPU, compact screen, low cost and innovations
such as using flash memory for storage rather than hard drives
with spinning platters. These factors combine to enable them to
run more efficiently and use less power than a standard form factor laptop. The Asus Eee PC is one example of an ultraportable. It
is the size of a paperback, weighs less than a kilogram, has builtin Wi-Fi and uses flash memory instead of a hard drive. It runs
Linux too
6 CONCLUSION
In this paper it is analyzed that the main motive of Green
Computing is the low amount of power consumption to
save time and money. There some IT industries those are
working on this concept. In this paper we have also focused on some technologies and techniques to make the
Green Computing successful. So Green Computing is the
emerging technology which is more over like aid and
need to sustain the eco-friendly environment.
To make the computer society completely green, one
should do the following things. When computer components are not in our use then the components must be donated to those people who may not have those components. Instead of discarding computers, upgrade their
parts in order to make them new. As some components
used to build the motherboard of computer are very expensive and toxic then recycling of these components is a
better option. Different wallpapers consumes a large
amount of energy so instead of setting different wallpapers, set Blackle as home page. Because blackle is a website powered by google custom search whose screen is
predominantly black and fonts are of gray color. This arrangement consumes very less energy. So, Go green is a
concept which is used in few organizations but if everyone use its components then it could be beneficial for everyone. The benefits of green computing are clear. As the
number of PCs approaches 2 Billion by 2015, the potential
savings related to energy use, CO2 emissions and e-waste
are undeniable. Hence proper implementation of Green
computing will be helping hand in terms to save energy
and remove the pollution.
