World Energy Model

Part of World Energy Outlook

In this report

Since 1993, the IEA has provided medium to long-term energy projections using the World Energy Model (WEM) – a large-scale simulation model designed to replicate how energy markets function. The WEM is the principal tool used to generate detailed sector-by-sector and region-by-region projections for the WEO scenarios. Download the WEM Methodology document for an in depth description of the overall approach and features of the model.
