Green Computing

Green computing refers to the practice and procedures of using computing resources in an environment friendly way while maintaining overall computing performance. Global warming is the continuing rise in the average temperature of the Earth’s climate system due to a range of factors. Scientific understanding of the various causes of global warming has been increasing since the last decade. Climate change and associated impacts vary from region to region across the globe. Nowadays, weather behaviour is becoming extremely unpredictable throughout the globe. United Nations Framework Convention on Climate Change (UNFCCC) is working relentlessly to achieve its objective of preventing dangerous anthropogenic (humaninduced) climate change. Owing to global warming, various regulations and laws related to environmental norms forces manufacturers of I.T equipments to meet various energy requirements. Green computing is a well balanced and sustainable approach towards the achievement of a greener, healthier and safer environment without compromising technological needs of the current and future generations. This paper is a survey of several important literature related to the field of green computing that emphasises the importance of green computing for sustainable development.
