By 2017, the ultra-connected society will access information in the cloud, mainly from smart phones, tablets and other mobile devices using ultra-broadband technologies. From the Cloud: children will access education through open online courses; people will access healthcare using remote online diagnosis; people will socialize on-line, watching video and listening to music; Companies and organizations will run their businesses. Users will rely on an average of 5 devices per person, with more than 20 billion devices connected. Over time, the digital universe will grow by a factor of 32 in 2020 compared to 2012 and mobile data traffic will grow 13 times.1
By 2017 more than 1.4 zettabytes will pass through the network (a zettabyte is a thousand billion gigabytes), the equivalent of everyone on earth tweeting nonstop for more than 100 years.2
By 2017 more than 5 zettabytes will be stored in the cloud (a zettabyte is a thousand billion gigabytes), the equivalent of storing 10 billion years of music.3
Information Communication Technologies consumed 6% of global energy in 2013, at approximately 108.4 gigawatts.4
As of 2013, devices consumed approximately 39 gigawatts (1GW is the typical capacity of 1 nuclear power plant) , the equivalent of 7 New York Cities.5
As of 2013, world-wide telecommunications networks consumed around 69 gigawatts (1GW is the typical capacity of 1 nuclear power plant) , the equivalent of 12 New York Cities.5
