3. Green computing:
Green computing, Green ICT as per IFG International
Federation of Green ICT and IFG Standard, green IT, or ICT
sustainability, is the study and practice of environmentally
sustainable computing or IT.
Origin :
In 1992, the U.S. Environmental Protection Agency launched
Energy Star.
4. Green technology
• Green computing, also called green technology
• It is the environmentally responsible use of computers and
related resources.
• 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”.
• Finding innovative ways to use IT in business processes to
deliver sustainability benefits across the enterprise and
beyond.
5. Goals :
They are similar to green chemistry:
• Reduce the use of hazardous materials
• Maximize energy efficiency during the product's lifetime
• Promote the recyclability or biodegradability of defunct
products and factory waste.
6. Government :
Government regulatory authorities also actively work to
promote green computing concepts.
• By 2008, 26 US states established state-wide recycling
programs for obsolete computers and consumer electronics
equipment.
7. Make computing usage more green:
Average computer users can employ the following general tactics to
make their computing usage more green:
• Use the hibernate or sleep mode when away from a computer for
extended periods
• Use flat-screen or LED monitors, instead of conventional cathode ray
tube (CRT) monitors
• Buy energy efficient notebook computers, instead of desktop computers
• Activate the power management features for controlling energy
consumption
• Make proper arrangements for safe electronic waste disposal
• Turn off computers at the end of each day
• Refill printer cartridges, rather than buying new ones
• Instead of purchasing a new computer, try refurbishing an existing
device
8. Green computing concepts :
The following four complementary approaches are employed:
• Green use
• Green disposal
• Green design
• Green manufacturing
9. • We can't live without PCs, so let’s learn how to live with them
in a way that makes them friendlier to the environment. Currently, PC’s
consume far too much electricity and generate too much e-waste to be
considered an Eco-friendly solution by today’s standards.
• With a typical PC taking approximately 110 watts to run, and with well
over 1 billion of them on the planet, it’s easy to understand what the
Silicon Valley Toxics Commission is saying about e-waste is being the
fastest growing part of the waste stream
Desktop Virtualization and
Eco-Friendly Computing
10. Strategies which help in
implementation of green computing
• Replacing Paper Systems with On-line Communication Systems
• Power Management
• Power Supply
• Algorithmic efficiency
• Terminal Servers
11. “Energy is neither created nor
destroyed. It moves from one form
to another.” Here we present 7 pc
concept that are:
Green
Clean
Recyclable
Sustainable steps by researcher
12. • Designed by Cody Stonerock,
• Made from recycled aluminum & biodegradable resins by HP
• PC has been made specially for the low cost desktop market.
• There are no screws or fasteners in this system.
13. • Monitor and other main components of the system can easily be
removed.
• So, as to ship them back to the company for repair or replacement.
• Since none of the components are fixed, users can simply replace a
broken component, which reduces wastes and encourages recycling.
• It is low cost desktop computer.
• Designed to feature fewer components and only offers basic
computing power.
14. It looks like a modern book rack. Though it is actually a PC,
updating it is as easy as replacing books in a shelf! Surprised?
Here, the hard drives, optical drives, PCl drives, graphics cards
and the RAM are all located as ‘books’ on this ‘bookshelf’ PC.
15. Whenever you want to modernize or upgrade a component, simply take
it off the ‘shelf’ and add the new one. The old component is sent back to
the company for recycling. The Igglu, thus, is an improvement over the
previous concept in the fact that, it can be upgraded into an advanced PC
also. The PC has been color coded for ease of replacements. It is also
designed for maximum energy efficiency and resource usage.
16. •US-based product designer has come up with the new concept for a
computing system.
• What you see is the 15-inch OLED screen display and docking space
for a notebook, a smartphone and a tablet PC.
17. Each of these are run by Li ion batteries which get recharged by solar
power. The computing systems come integrated with solar panels and a
1TB hard drive. Like the previous concept, it is built in the modular form
and can be easily upgraded. The solar charging is an added advantage. The
stored content can be transferred by simply docking two storage units
together.
18. The Froot was submitted as an entry by designer Paulina Carlos for
the DELL Regeneration Green Computing Technology Contest. This
concept goes one more notch above all the previous concepts
examined till now.
19. Bio degradable starch-based polymers constitute the ‘main frame’ and
can be recycled along with the electrical components that are part of it.
But here is the unique aspect; the Froot uses high-end laser and
projecting technology to beam a screen on the wall and a keyboard in
front of you! The ‘light’ keyboard acts like a normal keyboard and the
screen can be projected on any material. Need for a separate screen and
keyboard is also eliminated while the ergonomics of the same are not.
20. After we have witnessed the
paper thin computers and paper
light computers, it is the turn to
welcome the paper computer! The
entire computer has been built of
recycled, thick paper. This is the
creation of designer, Je Sung
Park. Thus, the problem of e-
waste in now completely gone!
Recycling the parts also is no
issue, as they can be easily
removed and sent to the company.
You only have the fear of tearing
your laptop!
21. Our final entrant in this list has been inspired by nature and is
extremely nature friendly! The LOOP uses an imaginative ‘usage
concept’ too along with its ‘design concept’. We have come across
the design concept before, where the PC is made modular with
components that you can upgrade.
22. Now, hear the fantastic usage concept; Dell has decided to rent out the components!
Yes! With the upgrades in the PC world arriving almost on a weekly basis, it does not
make sense to make regular purchases. Instead, you can hire the latest components from
the parent company and they take back the old components for recycling and reuse! The
LOOP comes in warm tones and a cool look. No screws go into the assembly and thus it
can be assembled in about 30 seconds flat! It is compact and has a design borrowed
from the cactus leaves. Overall, it is green and will make your neighbors go ‘green’ too!
23. ENERGY USE OF PC
• CPU uses 120 watts of energy
• CRT uses 150 watts of energy
---8hours of usage, 5 days a week= 562Kw.
Energy used comes from
Electrical current to run the CPU, motherboard , memory etc
Monitors
Printers
24. How to save energy while working on
the internet?
• Blackle is the website powered by Google custom search which aims
to save the energy consumed by the pc while working on the internet.
If a computer screen is:
White, it consumes 74W of energy
Black , it consumes 59W of energy.
Thus most of the companies have switched from Google to Blackle.

26. ADVANTAGES OF GREEN COMPUTING
• Reduces the amount of pollutants in the surroundings.
• It reduces the amount of heat produced from the electronic
devices.
• It encourages the use of renewable resources.
• It promotes effective utilization of natural resources.
• It reduces the risk existing in PC’s due to chemicals that cause
nerve damage in humans
27. Why green computing ?
• As we are familiar that plastic is a hazardous material, but the
electronic wastes (E-Waste ) is more hazardous than the plastic.
• The development and fabrication of an electronic device, we use
different kind of materials such as arsenic, antimony, lead , cadmium
etc.
•
• The U.S. generates more than 2 million tons of e-waste annually, and
nearly 90 percent of that ends up in landfills
• Disposal of such materials causes harm to the nature
and environment :THAT’S THE MAIN REASON OF GREEN COMPUTING
ESTABILISHMENT….
28. Disadvantages of green computing
• Green computing could actually be quite costly. The greenest
modern computers today are Mac books which are expensive
enough.
• Green computers may be considerably underpowered.
• Not fascinating for children.
• Rapid technology change
29. Conclusion
Adopting Green Computing Strategies make sense not only from an ethical,
or moral stand-point, but from a commercial stand-point.
There are many business benefits achievable through the implementation of
a green computing strategy such as cost savings, resilience, disaster
recovery, business continuity planning and of course public relations.
Green computing is the utmost requirement to protect environment and save
energy along with operational expenses in today's increasingly
competitive world. Adopting a holistic approach to greening IT is our
responsibility towards creating a more sustainable environment.
