Connected media devices energy consumption levels in France in 2018 and 2030

For the 2030 forecast, the source adds the following information:
"- The variation in the time spent on smartphones and computers is obtained by the increase in the time spent watching films and accessing the Internet.
- For televisions, the variation in IT infrastructure, usage time and energy efficiency only for the use of individuals was measured. Usage for advertisements was assumed to be constant, and anticipated energy efficiency was applied to it.
-The growth of networks and data centers was assumed to be half of that of video, knowing that it is this use that would ultimately generate half of the traffic.
-Energy efficiency is taken from the Négawatt study.
- For Internet boxes, in the absence of data, the source has assumed their constant consumption, knowing that, the standby mechanisms should largely compensate for unforeseen increases."
