Facebook , Ebay, Google and big data companies going green


According to http://www.datacenterknowledge.com/archives/2011/04/16/facebook-installs-solar-panels-at-new-data-center/   Facebook has built a 100 kW solar panel array, which will produce 204,000 kilowatt hours of solar power per year, next to its data center.  Greenpeace plans to launch a report at  http://event.gigaom.com/greennet/ event called “How Dirty Is Your Data?” which it explains as examining the “energy choices of Facebook and its IT peers.” At Green:Net Google and Yahoo will discuss their green data center plans.

For those electrical and electronics students here is some more interesting GK in your area of study.

Acccording to a MIT study in 2009  16,000 servers used by eBay are thought to use 60,000 MWh per year. Forty thousand servers used by Akamai are thought to use 170,000 MWh per year. For those that forget physics class, 1 megawatt (MW) is 1,000 kilowatts (kW). More details of this and other subject matters please click the following link.
