Drivers of energy consumption variation

Decreasing trend for the primary energy consumption  by 58 Mtoe between 2000 and 2017 essentially due to a lower consumption in the power sector (-54 Mtoe).  
Until 2015, the decreasing primary energy consumption (-81 Mtoe) was also due to 2 combined effect, a reduction in the final energy consumption (-40 Mtoe) and lower consumption in the power sector (-41 Mtoe).
