Empowering IT with Green Computing

In the existing state of Information Technology one cannot imagine of endurance without computers. The computers are used in such a way so as to help in sustaining the environment. The great amounts of energy consumed by large-scale computing and network systems, such as data centers and supercomputers, have been a major source of concern in a society increasingly reliant on information technology. The experts in the field have thought about how they can combat the continuing saga in battling the problem of scarcity and energy consumption by computing resources. This movement led to the development of “Green IT” and “Green computing”. “Green IT” refers to all IT measures that help in reducing energy either at hardware level, software level or at the service level. IT architect are moving towards new technologies and network system such as Virtualization, Grid Computing, MIMO System, Cognitive Radio and Power Management Techniques to achieve their goal of Green IT. This chapter incorporates the facts that how these new technologies helps in empowering IT.
