Cloud computing currently serves massive data loads across public and private clouds. However this poses a huge demand for energy support. The current system is mainly centered on coal and non-renewable energy based sources. A transition must be made towards green data centers which depend on renewable energy sources. According to the International Data Corporation, in 2010 for every $1 spent on hardware, 50 cents are spent on power and cooling. The authors expect that by 2013 for every $1 spent on hardware, $1 will be spent on power and cooling. This naturally prompts stakeholders of Fortune 500 companies to push towards a Green IT transition. GreenCloud based datacenters, in the long term are not only financially rewarding but also environmentally friendly.
