Green IT: Case studies

In 2008, Murugesan [1] has defined Green computing or Green IT as the study and practice of designing, manufacturing, using, and disposing of computers, servers, and associated subsystems-such as monitors, printers, storage devices, networking and communications systems-efficiently and effectively with minimal or no impact on the environment. Recently, studies are being conducted to indentify the main pollutant components in IT systems. The aim is to try to reduce their pollution factor, maximize their energy efficiency during the product's lifetime and promote their recyclability. You may think that the 3% value on the product is a negligible value, however, Terawatts are being consumed by Information Technology systems: software, hardware and communication. Sooner or later the green computing will be an integral and important part of the wider green association. The goal of this article is to study the influence of the IT system components (hardware, software and some case studies) on the environment and how to use them resourcefully. Some recommendations will also be presented throughout the article.
