Abstract
The rapid expansion in data centers, due to the
exponential growth of the cloud computing has caused
the sudden increase in energy consumption and its effect
on the environment in terms of the carbon lost. To
reduce the power consumption, it is required to develop
some energy efficient solutions. The Green Computing is
the practice of executing policies and the procedures to
improve efficiency of the computing resources in such a
way as to reduce the energy consumption and
environmental impact of their utilization. Green Cloud
Architecture is rising from these trends leading, not only
to energy efficiency, but also a carbon emission aware
concept. In order to reduce energy consumption, a green
environment needs to be construct[1]
Keywords: Green cloud computing, energy
efficiency, CO2 emission
Introduction
Green means eco-friendly while the cloud is the
representative of the internet service delivery model.
Green computing is also known as green information
technology (green IT).
Green computing introduces eco-friendly and
environmentally responsible usage of computers and
their resources associated with the IT industry and
services. In other words, it involves the designing,
engineering, and usage of computing devices in such a
way that it can reduce any destructiveeffect on the
environmental impact in the IT industry.
Green computing aims to attain economic viability and
improve the way computing devices are used. Green IT
practices involved the development of environment
sustainable production practices, energy-efficient
computers and improved disposal and recycling
procedures.
The five core green computing technologies are: Green
Data Center, Virtualization, Green Cloud Computing,
Power Optimization and Grid Computing.
Objectives
The main objective is to establish a new data centre
which consumes less amount of energy and releases
minimum amount of harmful gases into the environment.
It is possible only when we calculate the amount of
energy exhaust now in the existing system.
The purpose of green cloud computing is to develop the
recyclability or biodegradability of dead products and
factory waste by reducing the use of hazardous materials
and maximizing the energy efficiency during the
product's life span. [6]

Literature survey:
To promote green computing concepts, the following
four approaches are used:
• Green use: Minimizing the electricity
consumption of computers and their peripheral
devices and using them in an eco-friendly
manner
• Green disposal: Reuse of an existing equipment
or appropriately disposing of, or recycling,
unwanted electronic equipment
• Green design: Designing energy-efficient
computers, servers, printers, projectors and
other digital devices
• Green manufacturing: Minimizing waste during
the manufacturing of computers and other
subsystems to reduce the environmental effect
of these task[2]
Impact of Cloud Computing
Data centers are expensive to maintain, and also
unfriendly to the environment. Carbon emission due to
Data Centers worldwide is now more than both
Argentina and the Netherlands emission. High energy
costs and huge carbon footprints are incurred due to the
massive amount of electricity needed to power and cool
the numerous servers hosted in these data centers. [3]
We need green cloud computing solutions that
not only save energy, but also reduces the operational
costs and enrich environment sustainability.[13]
Green cloud computing
Green computing is the study and practice of
environmentally sustainable computing or Information
Technology. The green computing can be achieved by
reducing the overall power consumption. This can be
accomplished by redesigning the infrastructure of
network by reducing the number of servers, switches and
cables or by applying the different power consumption
schemes and patterns.[14]

Core component of Green Cloud Computing
Data Center: Data center is a subdivision of information
and communication technology service provider
organization where this organization can operate most of
the ICT infrastructure that supports to their clients. the
network system devices used in creating data centers are
switches, links and servers.

In the Green Cloud architecture, users submit their Cloud
service requests through a new middleware Green
Broker that manages the selection of the greenest Cloud
provider to serve the user’s request. A green request can
be of three types i.e., software, platform or infrastructure.
The Cloud providers can register their services in the
form of “green offers” to a public directory which is
accessed by Green Broker. The green offers consist of
green services, pricing and time when it should be
accessedfor least carbon emission. Green Broker gets the
current status of energy parameters for using various
Cloud services from Carbon Emission Directory. The
Carbon Emission Directory maintains all the data related
to energy efficiency of Cloud service. This data may
include PUE and cooling efficiency of Cloud datacenter
which is providing the service, the network cost and
carbon emission rate of electricity, Green Broker
calculates the carbon emission of all the Cloud providers
who are offering the requested Cloud service. Then, it
selects the set of services that will result in least carbon
emission and buy these services on behalf users.
The Green Cloud framework is designed to make their
service clean by keeping track of overall energy usage of
serving a user request. It relies on two main components,
Carbon Emission Directory and Green Cloud offers. [3]
Virtualization in Green Cloud Computing
Virtualization means to create a virtual version of a
device or resource, such as a server, storage device,
network or even an operating system where the
framework divides the resource into one or more
execution environments.[10]
Virtualization is the main key factor for Cloud
Computing to attain sustainability from the cost and
energy efficient point of view.[11]
There are two types of virtualization which are widely
used.
a) Server Virtualization: Virtual server allows several
machines to share the same physical server to run instead
of having their own server.
b) Storage Virtualization: Storing data across multiple
servers
Load Balancing
Load Balancing in Cloud Load balancing in clouds is a
mechanism that distributes the excess load evenly across
many servers. This technique is used to achieve user
satisfaction and resource utilization this helps in high
performance improvement.
a) Reducing Energy Consumption: Load balancing
helps in avoiding overheating by balancing the workload
across many servers.[4]
b) Reducing Carbon Emission: As the energy
consumption is reduced by load balancing. So we can
reduce the carbon emission by which we can achieve
green computing.[4]
Key Benefits of Green Computing
The concept of Green cloud computing has come after
the addition ofgreen with the cloud computing. The

green cloud presents a simulation environment for
energy aware cloud computing data centers.
This technology is beneficial as it:
Reduces energy consumption of computing
resources during peak operation.
Saves energy during idle operation.
Uses eco-friendly sources of energy.
Reduces harmful effects of computing
resources.
Reduces computing waste.
Conclusion:
Using green policies reduce carbon emission by almost
20%.Even though green cloud framework implant
various features to make cloud computing much more
green,there are still technological solutions are required
to make it a reality.
