There is no single story about the future of global energy and no long-term IEA forecast for the energy sector. It covers the whole energy system, allowing for a range of analytical perspectives from global aggregates to local details, such as the prospects for a particular technology or the outlook for end-user prices in a specific country or region. The first WEO was published in 1977 and it has been an annual publication since 1998, with the 2022 edition intended as a handbook for this year’s COP27 climate summit in Sharm El-Sheikh, Egypt.This year’s detailed projections are generated by the IEA’s Global Energy and Climate (GEC) Model, a large-scale simulation tool, developed at the IEA, which builds on over 20 years of modelling experience and is designed to replicate how energy markets function and reflect the latest developments of energy technology. Published every year based on objective data and dispassionate analysis, The World Energy Outlook (WEO) provides critical analysis and insights on trends in energy demand and supply, and what they mean for energy security, environmental protection and economic development.
