Energy crisis, global warming & IT industry: Can the IT professionals make it better some day? A review

Global Warming (¹GW) and Energy Crisis (²EC) have forced the researchers at teaching institutes, organizations, industry, research laboratories and other academia to study and minimize the power requirements of digital and electronic devices especially the huge amount of computers in the global village. Internet Data Centers (³IDC) are growing to large scale in Information & Communication Technology (⁴ICT) industry especially with the development of Cloud Computing (⁵CC) platform and their operation cost is of utmost importance to the energy suppliers. With the rise of new computing era i.e. Green computing there is a need to reduce the power consumption in IDC, Information Technology (⁶IT) equipments, processing of information and communication media that will result in lower Green House Gas (⁷GHG) emission. This research work will study Green Computing and will result in solutions to reduce the energy consumed by IT world. The paper also tries to summarize new research directions for new researchers in this field.
