The global energy challenges by Joachim SCHLEICH
Joachim SCHLEICH is Professor in Energy Economics, at Grenoble Ecole de Management.
At an overarching level, what is the key challenge for the energy system? Joachim addresses here this question through three points:
-
Energy demand and supply,
-
Social challenges of the energy system,
-
Transformation towards a sustainable energy system.

Since our last editions, the projections of energy demands have been updated to take into account the latest changes. Here is an updated chart of projected changes in energy demand between 2017 and 2040 based on the data from IEA (2018): World Energy Outlook. 
The electricity mix has also evolved. Below are two charts from IEA Global Energy & CO2 Status Report showing the energy generation by source and the distribution between the different sources.
