•  Data use is expected to grow by as much as 44 times, amounting to some 35.2ZB (zettabytes -- a billion terabytes) globally

•  Sensors, social media feeds, photos, video and cellphone GPS signals account for 2.5 quintillion bytes of data per day

•  More than 50% global population lives in cities and this number is forecast to rise to 69% by 2050

•  The number of city residents is expected to grow from 3.5 billion to 5 billion in the next 20 years

•  ‘Internet of Things’ Age is approaching: 25 billion devices connected to the Internet by 2015 and 50 billion by 2020

•  Access to public data is estimated to be worth €27 billion in the EU •  ICT-enabled energy efficiency could translate into over €600 billion

worth of cost savings for the public and private sector

•  From a rigid analog system to a smart, dynamic, digital and automated energy delivery system

•  How much excess energy will be available, when to sell it and whether the grid can transmit it?

•  When and where equipment downtime and power failures are most likely to occur?

•  Which customers are most likely to feed energy back to the grid, and under what circumstances?

•  Which customers are most likely to respond to energy conservation and demand reduction incentives?

•  How to manage the commitment of larger, traditional plants in a scenario where peaks from distributed generation are becoming relevant?
