Greenpeace released a report April 17 that looked at how “green” the cloud computing operations were for 14 major players in the industry. According to Greenpeace, some cloud data centers use as much electricity as 180,000 homes would use. Here’s a look at how the tech titans, such as Apple, Facebook and Amazon, stacked up against one another.
Facebook received a "D" in energy transparency, a "B" in energy efficiency and a "C" in renewables and advocacy. Facebook has taken steps to make its cloud computing operation more green. In October 2011, the social networking behemoth announced its new data center in Sweden. Facebook chose the European country partly because the company would have "access to renewable energy from hydropower facilities," the Associated Press reported.Alan Berner/AP
