Greener ICT: Feasibility of successful technologies from energy sector

Advances in Information and Communication Technologies (ICT) over the past few years have shown an exponential growth in technology and global presence. Hence, there is a need for solutions to optimize energy consumption in the ICT sector. Such solutions are collectively referred to as Green ICT. New technologies are perennially coming up, and hence a comprehensive research and analysis on the feasibility and effectiveness of the existing measures to control the carbon footprint of these new technologies is quintessential. In this paper, an overview of the existing strategies and policy recommendations is presented, but the principal focus is laid upon the analysis of successful eco-friendly methodologies such as Waste Heat Recovery, Smart Grids etc., that are implemented in the energy sector; and their effectiveness and feasibility in the ICT realm is discussed. Finally a comprehensive overview is presented on the overall best practices and strategies that could help the ICT sector towards technological and economic advancements.
