World Energy Outlook (WEO), the flagship publication by the International Energy Agency (IEA), is updated annually with the latest data, technologies, market trends and government policies. It is the most authoritative global source for energy analysis and projections. Covering the entire energy system, it uses multiple scenarios—ranging from exploratory pathways based on current policies to normative pathways designed to meet energy and emissions goals—to illustrate how different choices, contingencies and policy shifts could shape future outcomes for energy security, access and emissions. The 2025 edition arrives amid major changes in global energy markets and heightened geopolitical tensions, as governments pursue varying strategies to address security, affordability and sustainability. As always, the WEO offers unparalleled insight into the consequences of different energy policy and investment decisions, with a key focus this year on ensuring the security of supply of critical minerals.
