World Energy Outlook 2026

The IEA’s flagship World Energy Outlook (WEO) is the world’s most authoritative source of global energy analysis and projections. Updated each year to reflect all the latest energy data, technology and market trends, and government policies – it explores a range of possible energy futures and considers their implications for energy security, emissions and economic development.

Against the backdrop of the ongoing energy crisis stemming from the conflict in the Middle East, the WEO-2026 will contain multiple scenarios to help decision-makers assess the mid- to long-term implications of choices being made today.
