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.
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….
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
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.
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.
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
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.
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
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 : is becoming increasingly popular for
making casings for computers and peripherals.

EXAMPLES OF BAMBOO USAGE :-
Advantages:
Energy saving Environmentally Friend.
 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.

CONCLUSION



Adopting Green Computing Strategies make sense not only from
an ethical, or moral stand-point, but from a commercial standpoint.
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.

ANY QUESTION ?
1)Why screen saver in not effective now a days?
Ans) Now-a-days we generally uses an LCD inspite of CRT monitors.
thus “build in” property of CRT doesn’t exist in LCD, so screen
saver is not effective for energy saving.
2)How Blackle search saves energy?
Ans) Blackle is developed for saving the energy by displaying a black
background and using grayish-white font color for search results.
3)Is green computing is effective for future point of view?
Ans)Yes, because it provides an computing with eco-friendly.
Changing trends of technology day by day shows the big problem
of E- waste. Hence green IT is the best solution.
