Energy balances

Energy commodities (fuels) are mainly bought for their heat-raising properties. They can also be converted into different products (derived fuels). Therefore it is useful to present the energy supply and energy consumption in energy units (terajoules or tons of oil equivalent). The format adopted is termed the energy balance.

The energy balance allows to see the relative importance of the different fuels in their contribution to the economy. The energy balance is also the starting point for the construction of various indicators as well as analyses of energy efficiency.
