World Energy Outlook
The global energy scene is in a state of flux. Understanding the dynamic interplay of energy markets, technology and policy has never been more critical. The IEA flagship publication World Energy Outlook (WEO), widely regarded as the gold standard of energy analysis, provides strategic insight on what today’s policy and investment decisions mean for long-term trends. Based on rigorous modelling across different scenarios, the WEO projections are used by public and private sector stakeholders as a framework for policy-making, planning and investment decisions, and to identify pathways to a sustainable energy future.

World Energy Outlook 2017
The global energy scene is in a state of flux, with large-scale shifts in the global energy system. These include the rapid deployment and deep declines in the costs of major renewable energy technologies; a growing shift towards electricity in energy use across the globe; profound changes in China’s economy and energy policy, moving consumption away from coal; and the continued surge in shale gas and tight oil production in the United States.
These changes provide the backdrop for the World Energy Outlook-2017, which includes a full update of energy demand and supply projections to 2040 based on different scenarios. The projections are accompanied by detailed analyses of their impact on energy industries and investment, as well as implications for energy security and the environment.
The report this year includes a focus on China, which examines how China’s choices could reshape the global outlook for all fuels and technologies. It also has a focus on natural gas, which explores how the rise of shale gas and LNG are changing the global gas market as well as the opportunities and risks for gas in the transition to a cleaner energy system.
The WEO-2017 also introduces a major new scenario – the Sustainable Development Scenario – that outlines an integrated approach to achieving internationally agreed objectives on climate change, air quality and universal access to modern energy.
In addition, the WEO-2017 series includes two special reports, which will be available to download for free from this website:
- The Energy Access Outlook,released in Rome on 19 October, explores the close links between energy and development, assessing today’s global picture for access to modern energy, the strategies and technologies that can enable countries to achieve energy for all by 2030, and the ways in which reliable energy can move communities to meet the UN Sustainable Development Goals.
- The Southeast Asia Energy Outlook, released in Singapore on 24 October, examines the prospects for energy demand and supply in the ten countries of the Association of Southeast Asian Nations (ASEAN), where infrastructure and investment have to keep up with rapid, sustained growth in energy demand. The report covers the particular challenge of providing secure, clean and affordable energy to small island systems and remote settlements.
A full update of energy demand and supply projections to 2040 under different scenarios, and their consequences for energy security, economic prosperity, efficiency, investment, air quality and climate change
Major transformations in the global energy system over the next decades see renewables and natural gas as the big winners in the race to meet energy demand
Each year a series of WEO special reports highlight a specific and timely topic, such as air pollution or the water energy nexus, or focus on a country or region, such as Africa or Mexico
The first WEO was published in 1977, and has been published annually since 1998 - all WEO editions from 1994 onward are available for free download
The World Energy Model is a large-scale simulation model designed to replicate how energy markets function and is the principal tool used to generate detailed projections for the WEO scenarios
