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 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.

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.
