Energy consumption

  • Energy consumption decreased compared to 2005


    The gross domestic energy consumption amounted to 1,508 petajoules (PJ) in 2018. This concerns primary energy consumption without international aviation and shipping. Gross domestic energy consumption decreased by 2.9% in 2018 compared to 2017. Between 2005 (the reference year of the European Climate and Energy Package) and 2018, energy consumption went down by 9%

    The final energy consumption (all energy supplied to end users) increased slightly in 2018 compared to 2017. Compared to 2005, final energy consumption decreased by 2.4%.


  • Households consumed 16% less in 2018 compared to 2005

    Energy consumption in the transformation sector (mainly power plants and refineries) fell by 18% in 2018 compared to 2017 and by 31% compared to 2005. Consumption in the electricity sector in particular was 28% lower in 2018 than in 2017 due to a lower use of nuclear heat from the overhauls of Doel's nuclear power plants.

    Non-energetic consumption in industry (as raw material, solvent or lubricant) increased by 2.8% in 2018, as compared to 2017. Energetic consumption in industry increased by 1%. The chemical sector remains the largest industrial sector in terms of energy consumption, the second largest consumer of energy is the iron and steel industry.

    In the residential and service sectors (where the outdoor climate plays an important role), energy consumption remained more of less the same in 2018 compared to 2017. Compared to 2005, energy consumption in the residential sector has fallen by 16%.

    In the agricultural sector, energy consumption increased by 2.6% compared to 2017. Compared to 2005, it fell by 8%.

    The transport sector's energy consumption rose slightly by 0.5% compared to 2017. Compared to 2005, however, it rose by 5.8%.



Flemish Energy Agency (VEA): Flemish Energy Balance 


Primary energy consumption: the amount of energy that a geographical entity needs in order to be able to meet the demand for energy during the observed period. The primary energy consumption is equal to the sum of the primary energy production and the net import of energy. 


Gross domestic energy consumption: primary energy consumption minus bunkers used for international shipping and aviation. 


Final energy consumption: gross domestic energy consumption minus the energy consumed in the transformation sector (power plants, refineries and coke ovens). In other words, the amount of energy ultimately supplied to the final consumers of energy (industry, residential, services, agriculture and transport).

Petajoule (PJ): 1015 joule. Joule is the unit of energy.
