Green Computing:Techniques and Challenges in Creating a Friendly Computing Environments in Developing Economies

The adoption of ICT’s has currently realised advancements in technologies such as faster internet connectivity has changed the way we live, work, learn and play , it is affecting our environment in several ways. Today use of ICT has enabled and created many opportunities for employment round the globe, as the computer literacy becomes a prerequisite condition for sustenance in almost every sector. Besides this, ICT has impacted both positively and negatively on our environment. To grow awareness about environmental impact of computing, green technology is gaining increasing importance. Green ICT as a concept has been popularized to achieve energy efficiency and minimize consumption of energy by e-equipment. Climate change is one of the main environmental concerns being addressed globally; our environment has been changing thus posted more worrying because it is impossible to predict exactly how it will develop and what the consequences will be. Globally and even developed nations have been using various approaches to manage our environment. Green Computing is among the key techniques being implemented. The approaches required to achieve green computing as a technique includes both efficient hardware implementations and improving software methodologies of the various researchers. This paper aims to present green computing techniques and challenges, their impact on environment and creating a friendly computing environments in developing nations. The paper concludes by providing future directions of research.
