The World Energy Outlook (WEO), published every year by the International Energy Agency (IEA), is the most authoritative global source of energy analysis and projections. It identifies and explores the biggest trends in energy demand and supply, as well as what they mean for energy security, emissions and economic development.
The WEO-2024 Extended Dataset includes more detailed information at regional and country-level for Announced Pledges Scenarios (APS) and Stated Policies (STEPS) (including detailed energy balance, electrical capacity, electricity generation, CO2 emission by region, economic and activity indicators, etc.) across projected years (2030, 2035, 2040, 2045, 2050) as well as historical data (2010, 2015, 2022, 2023).
The aggregate for World and Advanced Economies (ADVECO) also includes the Net Zero Emissions (NZE) Scenario.
The Extended Dataset also includes chapter figures, investment, trade and power sector capacity addition and retirement, fossil fuel prices, refining capacity and runs, power generation technology costs and assumptions and air pollution data.
