## World Energy Outlook 2025 The **World Energy Outlook 2025 (WEO 2025)** is the flagship publication of the International Energy Agency (IEA) and is widely regarded as one of the most authoritative references on global energy trends. It provides in‑depth analysis of current market dynamics and long‑term projections, helping governments, companies and experts make informed decisions about the future energy system. ## Purpose and scope WEO 2025 examines how global energy demand, supply, investment and emissions may evolve under different policy and technology scenarios. It looks at fossil fuels, renewables, electricity, efficiency, and emerging low‑carbon solutions, assessing how they interact with economic growth, energy security and climate objectives. The report is updated each year so that its projections reflect the latest data, policy announcements and technological progress. ## Role for policy and business Policymakers use insights from WEO 2025 to design or adjust national energy and climate strategies, evaluate risks, and identify cost‑effective pathways for reducing greenhouse‑gas emissions. Businesses and investors rely on the report’s scenarios to understand potential future demand for various fuels and technologies, assess transition risks, and spot opportunities in clean energy markets. ## Authority and methodology The publication is considered highly influential because it combines detailed sectoral modelling with a transparent scenario framework, drawing on extensive data and consultation with member and partner countries. Its scenarios are not predictions, but structured “what‑if” pathways that illustrate how different policy choices and technological developments can shape the energy system over time. *** > “The IEA’s flagship World Energy Outlook (WEO) is the most authoritative source of global energy analysis and projections.” *** ### Author’s summary WEO 2025 is a yearly IEA report that maps possible futures for global energy, guiding policy and investment choices across fossil and clean technologies while linking energy trends to climate and security goals.
