Green Computing

This century is the century of IT revolution, advanced computers, and other electronic items. Due to rapid technological advancements, excessive dependence and tremendous use of electronic items carbon emission, global warming, climate change and saving our environment and ecology have become hot issues. Public as well as private sectors and societies have a new important agenda of tackling environment issues and adopting environment-friendly practices in the sector of computing as well. To reduce computer's environmental problems and to create a sustainable environment, we need to move towards Green Computing. Green Computing or Green IT benefits the environment by improving energy efficiency, lowering green house gas emissions using less harmful materials and encouraging reuse and recycling of the various components of electronic waste. The goal of green computing is to lower down the use of hazardous materials, maximize energy efficiency and popularize biodegradability or recyclability of out-dated products and factory waste. This paper focuses on the ideas and design on green computing, green computing practices and the negative impact on the environment.
