World Energy Resources

The World Energy Council, in the interest of ensuring a sustainable energy future for all, has been conducting the World Energy Resources study (former Survey of Energy Resources) since 1933.  The World Energy Resources report covers 12 major fossil fuel and renewable sources, with national assessment for all of the WEC’s member countries.  For over 80 years this highly regarded publication has been a reference tool for governments, industry, investors, IGOs, NGOs and academia.

This statistical report presents values for reserves and production of various resources at the global level. The World Energy Resources project team and its working groups collect and analyse data on specific resources and reserves. In addition to resource data the report also assesses current and emerging technologies, to provide a solid basis for energy policy and decision-making.

“The WEC is the only global organisation that gathers such a wide range of data covering finite resources, such as coal and gas, as well as nuclear and renewable sources, including geothermal, hydro and wind energy.”

The report aims to provide a comprehensive knowledge foundation for all policy and strategic decisions, including the answers to some of the energy sector’s most pressing questions:

  • When will the world run out of oil?
  • What is the status and potential benefit of shale gas, biomass, wind, solar and other renewable and fossil energy resources?
  • What are the issues impacting smart grids, energy-water linkages, carbon capture and sequestration, clean coal technologies, fourth-generation nuclear, or e-mobility?
  • What is the energy return on energy invested?

The World Energy Resources study group engages leading experts in reviewing resource data and other information and collects data from industry, government and academia across all regions. Individual members of the study group meet regularly to discuss trends in energy resource exploration and development.

The 2010  report is available to read online or download (11.75 MB).
