(d) International Targets/Recommended Standards: None.
(e) Linkages to Other Indicators: This indicator is closely linked with other
economic indicators, such as energy use per unit of gross domestic product (GDP),
energy prices, energy intensities and energy net imports; with environmental
indicators such as GHG emissions, air quality and waste generation; and with social
indicators such as household energy use for each income group.
METHODOLOGICAL DESCRIPTION
(a) Underlying Definitions and Concepts: Total primary energy supply (TPES) and
total final consumption (TFC) are key aggregates in the energy balances.
TPES comprises production of primary energy — for example, coal, crude oil, natural
gas, nuclear, hydro and other non-combustible and combustible renewables — plus
imports, less exports of all energy carriers, less international marine bunkers and
finally corrected for net changes in energy stocks. Production refers to the first stage
of production. International trade of energy commodities is based on the general trade
system; that is, all goods entering and leaving the national boundaries of a country are
recorded as imports and exports, respectively. In general, data on stocks refer to
changes in stocks of producers, importers and/or industrial consumers at the
beginning and the end of the year.
TFC refers to the sum of consumption by the different end-use sectors and thus
excludes energy consumed, or losses incurred, in the conversion, transformation and
distribution of the various energy carriers.
(b) Measuring Methods: This indicator is calculated as the ratio of the total annual
use of energy to the mid-year population. The following entries are to be specified for
the numerator of the indicator: total primary energy supply, total final consumption
and total final electricity consumption.
