Facebook has plans to build a running plant in Sweden 60 miles from the Arctic Circle. The plant will be running off hydroelectric power from a near by river that produces twice as much power as the Hoover Dam does. It will also have 14 backup diesel power generators.
The whole reason to build so far north is that the Arctic temperatures will help keep the servers cool and prevent them from melting down and crashing. This new European location is also going to create faster Facebook speeds throughout Europe. The project is expected to cost around 760 million dollars and will hopefully be completed by 2014.
