• Since the First Earth day that took place in
1970, our awareness about environmental
issues has increased many folds. Some of
them are:
• Global Warming resulting in heat waves,Global Warming resulting in heat waves,
droughts, rise in global temperature and more.droughts, rise in global temperature and more.

5. Defining Green ComputingDefining Green Computing
• Initiative taken in the direction of
computing resources which produce waste
energy that is adding to global warming is
Green computing also known as Green IT.
It is about::
• Using computer resources inUsing computer resources in
environmentally friendly wayenvironmentally friendly way
• Recycling digital devicesRecycling digital devices
• Reducing use of hazardous materialsReducing use of hazardous materials

6. Need for Green ComputingNeed for Green Computing
• An average PC wastes half the energy it
consumes which not only results in
additional electricity bill but the wasted
electricity contributes to global warming.
• Just by using the power management
feature of a PC or laptop and buying
energy efficient systems, impact of
computers on the environment can be
reduced.

7. Need for Green ComputingNeed for Green Computing
Some green computing practices are as
follows:
•Power-down CPU, monitor and all
peripherals after use.
•Energy-intensive peripherals like laser
printers can be powered as per need.
•LCD and LED monitors can be used.
•Using notebook computers.

8. Need for Green ComputingNeed for Green Computing
• Disposal of e-waste according to federal,
state and local regulations.
• Employ alternative energy sources for
computing workstations, servers, networks
and data centers.
• Reducing carbon footprints.
• Making use of technology wisely.
• Evaluating systems and technology before
adopting it.

9. Importance of Green ComputingImportance of Green Computing
• Business organizations are waking and
also making an effort in the direction of
green computing.
• There are energy smart desktops from
DELL like OptiPlex 755 Energy Smart MT,
OptiPlex 755 Energy Smart USFF, DELL
Precision 490 and many more.
• It encourages the use of environmental
friendly products in an efficient way.

11. Path towards GreenPath towards Green
• Green computing is somewhat related to
other movements like reducing the use of
environmentally hazardous materials like
CFCs, using recyclable materials,
minimizing use of non-biodegradable
components, and encouraging use of
sustainable resources.
• Green computing basically takes into
account economic viability, social
responsibility and environmental impacts.
11Green Computing: An Environmental Necessity

12. Path towards GreenPath towards Green
• Following Green IT regulations like EPEAT,
Energy Star 4.0 standard, RoHS Directive,
and W.E.E.E. Law.
• Industry association for Green Computing:
Uptime Institute Inc., Climate Savers
Computing Initiative and Green Grid.
• Green Data Centre Initiative like energy
conservation and virtualization.
• Adopting eco-friendly practices like
refurbishing and recycling.

13. Issues and ChallengesIssues and Challenges
• In the last ten years, computer-related
energy consumption has increased five-
fold.
• The recent computing efforts that are
coming up like pervasive computing, nano
computing, quantum computing,
ubiquitous computing and many more
should keep the requirements of green
computing in mind and develop there
environmental friendly products.

Green Computing: An Environmental Necessity

14. Issues and ChallengesIssues and Challenges
• Efforts should be made to have products
which utilize the enormous energy
available in the form of waste energy, solar
energy, nuclear energy and many more
forms of energy.
• Education institutions can make students
aware about Green Computing through
seminars and programs.
