Final energy consumption covers energy supplied to the final consumer for all energy uses. Final energy consumption means that no useful energy source is left, unlike the use for conversion, which yields useful energy sources.
Final energy consumption is defined as the use of energy for the generation of heat, light or power. Non-energetic final consumption is the use of energy sources for making products which do not carry energy. The energy used for the production process is stored in the product.
Instances of final energy consumption are the combustion of natural gas in boilers, household electricity consumption and the consumption of motor fuels for transport. Instances of non-final energy consumption are the use of petroleum as raw material for the manufacture of plastics or natural gas for artificial fertilizers.
