Total Primary Energy Supply in V4

Total primary energy supply per capita is a common, albeit an imperfect measure of energy efficiency in a country. This OECD figure refers to total primary energy supply (TPES) per head of population. The ratio is expressed in tonnes of oil equivalent (toe) per person. TPES consists of primary energy production adjusted for net trade and stock changes. Production of secondary energy (e.g. oil/coal products, electricity from fossil fuels, etc.) is not included since the "energy equivalent" of the primary fuels used to create the secondary products or electric power has already been counted. TPES is expressed in tonnes of oil equivalent (see the IEA sources below for details on how TPES is calculated). The forecasts provided in the table refer to the Reference Scenario of the World Energy Outlook.



This data is not the actual energy intensity of a country, because it does not take the differences in gross domestic product into effect. However, it is a good first measure to have an impression about the size and development of an energy market.
