Energy-saving servers: Data storage 2.0

Whether it's sending the grandparents a few pictures of the kids, streaming a movie or music, or surfing the Internet for hours, the volume of data our society generates is increasing all the time. But this comes at a price, since storing data consumes huge amounts of energy. Assuming that data volumes continue to grow in future, the related energy consumption will also increase by several orders of magnitude. For example, it is predicted that energy consumption in the IT sector will rise to ten petawatt-hours, or ten trillion kilowatt-hours, by 2030. This would be equivalent to around half of the electricity produced worldwide.
