Introduction to "Green Computing"

The planet we live in has settled many facilities of living for us. These facilities work in special conditions and need specific prerequisite to continue their tasks. Otherwise there are many factors would stop our environment from working properly. One of the results of improper function of environment is global warming. Global warming leads nature to destruction. One way to prevent global warming is implementing green computing. Wikipedia defines green computing as this: "Green computing or green IT, refers to environmentally sustainable computing or IT." This definition means preventing computers to damage environment or use computing to improve the situation of nature for any organisms, especially humans.

San Murugesan defined green computing field in the article "Harnessing Green IT: Principles and Practices" as this: "the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems—such as monitors, printers, storage devices, and networking and communications systems — efficiently and effectively with minimal or no impact on the environment." This goal can affect different aspects of computing and IT. These aspects can be involved of making hardware which use less electricity or new software that control the amount of light which are turned on in a big office. One of the important issues in green computing is recycling any devices or equipment which using in IT or computing. E.g. Parts which used in computers or laptops or recycling used papers and use recycled papers.

Alongside of many different ways for reducing the usage of electricity by computers, there are many efficient ways for reducing the human usage of electricity in daily life. As Patrick Kurp said in his article, "In recent years, Microsoft and other companies have built data centers in central Washington to take advantage of the hydroelectric power produced by two dams in the region. The Microsoft facility, which consumes up to
