World Energy Outlook 2025 (October 2025) The IEA’s flagship World Energy Outlook (WEO) is the most authoritative source of global energy analysis and projections. Updated annually to reflect the latest energy data, technology and market trends, and government policies, it explores a range of possible energy futures and their implications for energy security, access and emissions. The WEO covers the whole energy system, using a scenario-based approach to highlight the central choices, consequences and contingencies that lie ahead. It includes exploratory scenarios that flow from different assumptions about existing policies, as well as normative pathways that achieve energy and emissions goals in full. The multi-scenario approach illustrates how the course of the energy system might be affected by changing key variables, including the energy policies adopted by governments around the world. This year’s edition comes amid major shifts in global energy policies and markets, and acute geopolitical strains. Governments are reaching different conclusions about the best ways to tackle concerns about energy security, affordability and sustainability. As always, the World Energy Outlook provides unrivalled insights into the consequences of different energy policy and investment choices. An important theme in this year’s WEO is security of supply of critical minerals. https://idrawater.org/wp-content/uploads/2026/03/IEA-World-Energy-Outlook-2005.pdf
