In the information age the important concern for human beings is related to environment protection. The need of the hour also implicates that every items and subjects we used in betterment of our life has some good or bad consequences on the environment. Computers could not be excluded from such category. After a long use of computers when the time comes for disposal we just throw it away which do nothing good to environment except as a non biodegradable waste. These non degradable wastes add to the woe of climate changes. Here we need green computing which is environment friendly. Green computing is all about the efficient use of computers and computing. The whole concept is to make computers friendlier to the environment, economy and society. Earlier computers are made considering the economic viability to the buyer. But in green computing manufacturers must consider the social responsibility and the impact of the environment apart from the economic viability before create computers. This way a computer could be disposable or recycled after it is used for a specific time period. The concept is to convert the use, creation and end of computers more eco friendly from beginning to end. Another aspect of green computing is how we use it which determines the amount of energy we spend on it. Many a time we leave the monitor or computer without turning it off. The result is we end up in using extra energy which we could save if turn it off when it is not in use.

For green computing the need is to create efficient systems those will implement all factors which would be environment friendly. It could be achieved if the hardware’s life is extended, its maintenance cost reduced and recycling of the waste computer easier than earlier. This will have little impact on the environment in a negative way which is the basic goal of the green computing. As a result of global warming and consumer awareness PC manufacturers giving importance to this aspect of computer manufacture. These eco-friendly computers would use less electricity and are made of recycled steel, aluminum or plastic. The screen and key boards could also be made of such recycled substances. The emission of any hazardous gas could then be stopped by using such eco-friendly computers which also looks like a fashionable. The making of green PCs would be a vital step towards tackling the climate change.
