Total primary energy supply (TPES) is the total amount of primary energy that a country has at their disposal. This includes imported energy, exported energy (subtracted off) and energy extracted from natural resources. Usually TPES is thought of as being the sum of all primary energy sources, but some end use energy must be taken into consideration. This comes from the fact that TPES includes both imports and exports. The net amount of electricity traded (imports - exports) and the net secondary fuels (for example amount of gasoline imported - amount of gasoline exported) become part of the TPES.
In contrast to the total primary energy supply, countries have a total final consumption of energy, which focuses on the end use energy.
