For 60 years, the BP Statistical Review of World Energy has provided high-quality, objective and globally consistent data on world energy markets. The Review is one of the most widely respected and authoritative publications in the field of energy economics, used for reference by the media, academia, world governments and energy companies. A new edition is published every June.

BP Statistical Review of World Energy June 2011

Methodology

The following methodological changes have been made to this year’s Review:

  • Fuels used as inputs for conversion technologies (gas-to-liquids, coal-to-liquids, and coal-to-gas) are counted as production for the source fuel and the outputs are counted as consumption for the converted fuel.
  • A new table has been added to the Review for consumption of commercial electricity produced from renewable sources. Electricity from renewable sources is converted to tonnes of oil equivalent following the same methodology used for nuclear and hydroelectricity, and is included in the primary energy consumption calculation. • A new table has been added for biofuels production. Biofuels consumption continues to be included in oil consumption data (see footnotes to oil consumption table).
