2. Introduction
 Green Computing is “ Where organizations adopt
a policy of ensuring that the setup and operations
of Information Technology produces the minimal
carbon footprint” .
 Green computing is the term used to denote
efficient use of resources in computing , it is also
known as Green IT .
 Green computing is the study which emphasizes
on the operation of computers and its peripherals
in order to minimize the carbon footprint. Green
computing had given the perspective to think in
the direction that technology is not only meant for
accomplishment of our tasks but also making

3. NECESSITY OF GREEN
COMPUTING
 Reduce energy consumption of computing
resources during peak operation
 Save energy during idle operation
 Use eco-friendly sources of energy
 Reduce harmful effects of computing resources
 Reduce computing wastes

4. Eco Friendly Approach
 Electronics giants are about to roll out eco-friendly
range of computers (like desktops and
laptops) that aim at reducing the e-waste in the
environment.
 Energy-intensive manufacturing of computer
parts can be minimized by making manufacturing
process more energy efficient.
 Power-sucking displays can be replaced with
green light displays made of OLEDs, or organic
light-emitting diodes
 Landfills can be controlled by making best use of
the device by upgrading and repairing in time with
a need to make such processes (i.e., up
gradation and repairing) easier and cheaper

5. Eco Friendly Approach
 Use of toxic materials like lead can be replaced
by silver and copper making recycling of
computers (which is expensive and time
consuming at present) more effective by recycling
computer parts separately with an option of reuse
or resale.
 By replacing petroleum-filled plastic with bio
plastics—plant-based polymers— which require
less oil and energy to produce in comparison to
traditional plastics with a challenge to keep these
bio plastic computers cool .

6. CHALLENGES IN GREEN
COMPUTING
 Equipment power density / Power and cooling
capacities.
 Increase in energy requirements for Data Centers
and growing energy cost.
 Control on increasing requirements of heat
removing equipment, which increases because of
increase in total power consumption by IT
equipment’s.
 Equipment Life cycle management – Cradle to
Grave.
 Disposal of Electronic Wastes.

7. FUTURE OF GREEN
COMPUTING
 Recyclable paper laptop :
One of the most environmentally
friendly computers that you can think of purchasing
is the Recyclable Paper Laptop. This concept
laptop is crafted from papers that have been
recycled or pulp materials that are essentially
packed in layers.
 IMEC laptop :
This unique laptop can be easily
powered using just two solar cells and encourages
people to understand the importance of solar
energy or alternative energy.

8. FUTURE OF GREEN
COMPUTING
 Life book Leaf multipurpose laptop :
The idea of designing
such a concept based laptop came to designers
Carl Burdick and Laura Karnath who were
competing for the “Fujitsu Design Award - A life with
future computing”. Some of the other exciting
features of the gadget include OLED touch screen
that spreads out easily and can be conveniently
folded as a laptop. Its exterior is carved out of
polycarbonate, which is optically sensitive material
and shatterproof as well.

9. FUTURE OF GREEN
COMPUTING
 LOOP-Ecofriendly desktop computer :
Better known as the
LOOP, you will have to place an order for this
system online so that it can be delivered to your
home directly.
 EVO PC Concept :
The EVO PC that is made from
materials that are sustainable as well helps a great
deal when it comes to reducing carbon footprint in
comparison to the traditional computers.

10. FUTURE OF GREEN
COMPUTING
 Compaq EOS sustainable desktop :
This gadget incorporates
very few components and offers basic computing
power only. None of the components in this system
are fixed, which makes it easy for the consumers to
replace any broken component with ease and
thereby reduce e-waste and promote recycling.
 Igglu modular PC concept :
This system incorporates color
coded and hot swappable modules for optical
drives, hard drive, graphic cards, RAMS and PCI
drives. Users can easily replace these modules and
send them back to the company for recycling.

11. FUTURE OF GREEN
COMPUTING
 'Bento' solar-powered concept :
The credit for designing
this solar powered system goes to Rene Lee, an
American product designer. This system is
essentially a combination of notebook, Smart
phone and tablet computer that are all packed in a
single system.
 Solar Laptop Concept :
The solar laptop concept is the
brainchild of designer Nikola Knezevic and is
perfect for safeguarding the environment as well as
minimizing your electric bill. The top half portion of
the laptop is attached to a solar panel that is
capable of extracting the maximum amount of sun.s
rays when it is folded out.

12. Carbon free computing
 It has been estimated that the concentration of
CO2 is increasing day to day very quickly. The
other gases which affect the greenhouse are
methane (CH4), nitrous oxide (NO2) and
fluorocarbons (CCl4). These gases are able to
increase the temperature of the earth, which
causes to lead the drought and floods and rising
the sea level. These also affect the life on earth.
In 1997 Kyoto in USA tried to reduce the emission
of CO2 from electronic devices and other
devices. These devices are manufactured in such
way that they take less energy.

13. CONCLUSION
 Technology is not a passive observer, but it is an active
contributor in achieving the goals of Green Computing. IT
industry is putting efforts in all its sectors to achieve Green
computing. Equipment recycling, reduction of paper usage,
virtualization, cloud computing, power management, Green
manufacturing are the key initiatives towards Green
computing.
 Current challenges to achieve Green Computing are
enormous and the impact is on computing performance.
Efforts of Governments and Non-Government
Organizations (NGOs) are also appreciate-able.
 Government regulations are pushing Vendors to act
green; behave green; do green; go green; think green; use
green and no doubt to reduce energy consumptions as
well. All these efforts are still in limited areas and currently
efforts are mainly to reduce energy consumption, e-Waste
but the future of Green Computing will be depending on
efficiency and Green products. Future work in Green
Computing discipline will also rely on research work in
academics since this is an emerging discipline and there is
much more need to be done. There is need for more
