Green computing is the practice of using computing resources efficiently. In the article Harnessing Green IT; Principles and Practices, San Murugesan defines the field of green computing as "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 ao no impact on the environment. "The goals are to reduce the use of hazardous materials, maximize energy efficiency during the product’s lifetime, and promote recycl- ability or biodegradability of defunct products and factory waste. Green computing is the environmentally responsible use of
computers and related resources. Such practice include the implementation of energy - efficient central proccessing units, servers, peripherals as well as reduced resource consumption and proper disposal of electronic waste. One of the earliest initiatives toward green computing in the United States was the voluntary labeling program known as Energy Star. It was conceived by the Environmental Protection Agency (EPA) in 1992 to promote efficiency in hardware of all kinds. The energy star label became a common sight especially in laptops and displays. Similar programs have been adopted in Europe an Asia. As 21st century belongs to computers, gizmos and electronic items, energy issues will get a serious ring in the coming days as the public debate on carbon emissions, global warning and and elimate
change gets hotter. If is estimated that out of 5250 million per year spent on powering computers worldwide only about 15% of that power is spent computing the rest is wasted idling. Thus energy saved on computer hardware and computing will equate tones of carbon emissions saved per year.Taking into consideration the popular use of information technology industry, it has to lead a revolation of sorts by turning green in a manner no industry has ever done before. Opportunities lie in green technology like never before in history and organizations are seeing it as a way to create new profit centers while trying to help the environmental cause. As computers play an everlarger role in our lives, energy demands, costs and waste are escalating dramatically, Consider the following from the Climate Sav-
