3. DEFINITION - WHAT DOES GREEN COMPUTING
MEAN?
 Green computing practices came in 1992, when the
Environmental Protection Agency (EPA) launched the Energy
Star program.
 Green computing is also known as green information
technology (green IT).
 Green IT :-Green computing is the environmentally
responsible and eco-friendly use of computers and their
resources.

4. 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 RESON OF GREEN
COMPUTING ESTABILISHMENT

5. ROADS TO GREEN COMPUTING :
 Green use: Minimizing the electricity consumption.
 Green disposal: Re-making an existing computer or
recycling, unwanted electronic equipments.
 Green design: Designing energy-efficient computers, and
other digital devices.
 Green manufacturing: Minimizing waste during the
manufacturing of computers and other subsystems to reduce
the environmental impact of these activities

6. GENERAL TACTICS TO MAKE COMPUTING USAGE MORE
GREEN:
 Turn off computers at the end of each day.
 Use power saver mode.
 Use liquid-crystal-display (LCD) monitors rather than cathode-ray-
tube (CRT) monitors.
 Don’t print unless necessary .
 Dispose of e-waste according to federal, state and local regulations.
 Instead of purchasing a new computer, try refurbishing an existing
device.
 Use hardware software with a energy star label.

7. STRATEGIES WHICH HELP IN IMPLEMENTATION
OF GREEN COMPUTING
 Replacing Paper Systems with On-line Communication
Systems.
 Power Management .
 Power supply.
 Algorithmic efficiency.
 Terminal Servers.
 Storage.
 Operating system issues.
 Materials recycling.

8. GREEN DISPOSAL
 Reuse:- donate your computer components to people who may not
have or have lesser quality computers.
 Refurbish: rather than discarding your computer upgrade it.
change its some of the parts in order to make it new.
 Recycle

9. HOW TO SAVE ENERGY WHILE WORKING ON
THE INTERNET:
 Blackle is the website powered by Google custom search and
created by Heap Media, which aims to save energy by displaying a
black background and using grayish-white font color for search
results.
 Blackle saves energy because the screen is predominantly black.
 Set blackle as your homepage.

10. ENERGY USE OF PC
 CPU uses 120 watts
 CRT uses 150 watts
-8 hr of usage,5 days a week =562 K watts.
 Energy use comes from:-
 Electrical current to run the CPU, motherboard, memory.
 Monitors
 printers

11. GREEN MANUFACTURING
 Recyclable plastics : computers are constructed from
non-recyclable plastics ,i.e. Recyclable polycarbonates
resin.
 Volume reduction : remove hazardous portion of waste
from non hazardous portion.
 Bamboo:It is becoming increasingly popular for making
casings for computers and peripherals.

12. EXAMPLES OF BAMBOO USAGE :-

13. Advantages:
 Energy saving Environmentally.
 Save more money per year.
 Green computing techniques will actually translate into a
much lower carbon dioxide emission
Disadvantages:
 High start up cost.
 Still in experimental stages.

15. 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 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.
