Review on Green computing to save environment and power management

Computers are used everywhere in human life hence computer consumes more electricity.Toxic, carbon dioxide produce by computer material. But use of computer is necessary in human life. Existence of Green Computing to overcome negative effect of computer to environment.Green computer solves  the problem of power consumption of computer system. It also provides technique to minimize pollution by computer material. Moreover, thousands of computing devices are manufactured every day and the same amount of old computers is being thrown away loading up the e-wastes. So it is highly important to manage these computing devices in such a way that they last longer and even if they are disposed of, they shouldn’t cause much harm to the nature. Green computing can take many forms in itself. Green technology focuses on reducing the environmental impact of industrial processes and innovative technologies caused by Earths growing population It has taken upon itself the goal to provide society’s needs in ways that do not damage or reduce natural resources. It is mainly used to protect environment, optimize energy consumption and keeps Green environment. The main goal of green computing is that increasing energy efficiency and reducing the use of harmful materials. Green computing ultimately focuses on ways in reducing overall environmental impacts. It require the integration of Green computing Practices such as recycling, electronic waste removal power consumption, virtualization, improving cooling technology, and optimization of the requirements. The major power consumption components are processors and the main memory in the servers.This paper gives idea of saving energy & environment which helps to save money
