World Energy Outlook

The gold standard of energy analysis

About the WEO

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.

The first WEO was published in 1977 and it has been an annual publication since 1998. The detailed projections are generated by the World Energy Model, a large-scale simulation tool, developed at the IEA over a period of more than 20 years that is designed to replicate how energy markets function. It covers the whole energy system, allowing for a range of analytical perspectives from global aggregates to elements of detail, such as the prospects for a particular technology or the outlook for end-user prices in a specific country or region.

There is no single story about the future of global energy and no long-term IEA forecast for the energy sector. The WEO uses a scenario-based approach to highlight the key choices, consequences and contingencies that lie ahead, and to illustrate how the course of the energy system might be affected by changing some of the key variables, chief among them the energy policies adopted by governments around the world.

This year’s exceptional circumstances require an exceptional approach. The usual long-term modelling horizons are kept but the focus for the World Energy Outlook 2020, to be released on 13 October, is firmly on the next 10 years, exploring in detail the impacts of the Covid-19 pandemic on the energy sector, and the near-term actions that could accelerate clean energy transitions.

The analysis targets the key uncertainties facing the energy sector in relation to the duration of the pandemic and its implications, while mapping out the choices that would pave the way towards a sustainable recovery.

The strategic insights from the WEO-2020 are based on detailed modelling of different potential pathways out of the crisis, covering all regions, fuels and technologies and using the latest data on energy markets, policies and costs.

World Energy Outlook 2019

The World Energy Outlook series is a leading source of strategic insight on the future of energy and energy-related emissions, providing detailed scenarios that map out the consequences of different energy policy and investment choices. This year's edition updates the outlooks for all fuels, technologies and regions, based on the latest market data, policy initiatives and cost trends.
