Green Computing - Trends and Challenges

Abstract

Green computing is the environmentally responsible use of computers and related resources. It is the study of efficient and eco-friendly computing. The rationale behind energy efficient coding is to save power by getting software to make less use of the hardware, rather than continuing to run the same code on hardware that uses less power. The concept of green computing has begun to spread in the past few years, gaining increasing popularity. IT industry is putting efforts in all its sectors to achieve Green Computing. The study emphasis on current trends, challenges and the future trends of Green Computing. The main aim of green computing is to lessen down the use of hazardous materials, maximize energy efficiency and biodegradability or recyclability of out-dated products and factory waste of the computer factory. The major concern of present scenario is to prepare such equipments by which efficient energy can be utilized, to minimize e-waste and use of non toxic materials in preparation of e-equipments. We can implement green computing in computer’s fields as CPU servers and other peripheral devices (mobile devices). It has been seen that computers and other electronics devices are increasing day by day, so the amount of electricity consumed by them is also increasing. In this way the percentage of co2 in the atmosphere is also increasing. The other toxic materials which are used in electronics industry are also harmful for environment. Equipment Recycling, reduction of paper usage, virtualization, cloud computing, power management, Green manufacturing are the major initiatives towards Green computing.
