main scenario assumptions
To develop a global energy scenario requires a model that reflects the significant structural differences between different countries’ energy supply systems. The International Energy Agency breakdown of ten world regions, as used in the ongoing series of World Energy Outlook reports, has been chosen because the IEA also provides the most comprehensive global energy statistics. In line with WEO 2011, this new edition maintains the ten region approach.
The countries in each of the world regions are listed in Figure 4.1.
