A Survey of Green Computing

Green computing is the study and practice of using computing resources efficiently. Green Computing is one of the hottest subjects these days for people in industry, academia and even for businesses. The major benefits of using Green Computing (including energy-aware, and power-aware) is not perfectly clear in terms of monetary cost, performance, and the amount of pollutants such as carbon footprint. This paper mainly discusses why we need green computing and approaches to green Computing. This paper also discusses some of the recent implementations of green computing. The main aim of this paper is to reduce the use of hazardous materials, maximize energy efficiency during the product's lifetime, and promote recyclability or biodegradability of defunct products and factory waste. The plan towards green IT should include new electronic products and services with optimum efficiency.
