Cheap and abundant electricity from renewable sources makes northern Scandinavia an attractive place to house power hungry data centers, analysts say. Pictured is the Porjus hydropower plant in Lulea River (Lule Älv), which helps power some the area's data centers. courtesy of Vattenfall
Facebook was once scolded by Greenpeace for obtaining 53% of its electricity from coal sources. It has since stated its intention to go green.
Other companies to set up shop in northern Scandinavia include Google, UK-based data-storage specialist firm Hydro66, and Bitcoin-mining group KnCMiner. courtesy jonathan nackstrand

However, not everyone is convinced that data can be most effectively stored in this part of the world. Some analysts point to data protection laws that require certain types of sensitive information, like medical records, to be stored within particular jurisdictions. courtesy of verneglobal
Big financial institutions, meanwhile, require servers to be located close to trading operations in order to take advantage of split second change of market prices. courtesy of verne global
