In an April 2011 report entitled “How Dirty is your Data?” the non-profit Greenpeace examined energy sources for the 10 largest IT companies involved in cloud computing, finding Apple, Facebook and IBM especially guilty of getting significant amounts of power from coal-fired power plants. (Facebook had come under fire earlier this year when reporters uncovered that the company planned to buy electricity for its brand new eco-friendly data center in Prineville, Oregon—one of the greenest such facilities ever designed and constructed—from a utility that derives most of its power from coal.) Yahoo, Amazon.com and Microsoft scored best in use of renewable alternative energy sources for cloud services.
In the long run, analysts think that the widespread shift to cloud computing will be a great boon to the environment. A report released in September 2011 by Pike Research, “Cloud Computing Energy Efficiency,” predicts that because of the shift to cloud computing and increasing efficiencies, data center power consumption will decrease by 31 percent between 2010 and 2020.
