World primary energy production is the world-wide production of primary energy from fossil, nuclear and renewable sources. Primary means: extracted or captured directly from natural sources.

Energy sources are usually classified as

  • fossil, using coal, lignite, petroleum and natural gas,
  • nuclear, using uranium,
  • renewable, using hydro power, biomass, wind and solar energy, among others.

The table lists the top 16 countries producing about 70% of the total of all more than 190 countries. These 16 with the 28 countries of the EU produce 78%. The amounts are given in million tonnes of oil equivalent per year (Mtoe/a, 1 Mtoe = 11.63 TWh). The data are of 2012.[1]

Primary energy assesment.[2]

  • Fossil: based on net calorific value.
  • Nuclear: heat produced by nuclear reactions, 3 times the electric energy, based on 33% efficiency of nuclear plants.
  • Renewable: biomass based on net calorific value. Electric energy produced by hydro power, wind turbines and solar panels.[3] Geothermal heat used in power plants is set at 10 times the electric energy, assuming 10% efficiency.

52% of world energy production is petroleum and natural gas. Kuwait, Norway and Qatar export more than 80% of oil and gas, Saudi Arabia and Arab Emirates more than 70%.
