Big data, big networks, big infrastructure- An overview of the electricity used by the global digital ecosystem

A study by Digital Power Group

The information economy is a blue-whale economy with its energy uses mostly out of sight.

The ICT ecosystem now approaches 10% of world electricity generation. Or in other energy terms – the zettabyte era already uses about 50% more energy than global aviation. This recent study (August 2013) by Digital Power Group includes interesting facts about the use of electricity by smart phones and tablets.
