Study of Green IT: Present to Future

The exponential growth in users of computer over the years has impacted environment drastically. A primary concern of this paper is to study the transformation of computer state from grey to green. Green IT is basically referred to Green computing . this study shows how the emerging green technology reduces the negative impact of computing on the environment. The goal of green computing is simple: reduction in the use of harmful materials, maximizes energy efficiency, and promotes recyclability. The idea is to ensure the least human impact on the environment. 'Green Computing 'has moved research into energy-saving techniques from home computers to enterprise systems' Client and Server machines. Saving energy or reduction of carbon footprints is one of the aspects of Green Computing. The research in the direction of Green Computing is more than just saving energy and reducing carbon foot prints. This study provides a brief account of Green Computing. Here, the concept of green computing and its core ideals in detail, including what it is, why it's needed and some ideas for the future has been discussed.
