Overview

Due to data quality issues, comparisons are made with 2005 data, rather than 2000 data.

In 2021, the final energy consumption in Belgium was 32.2 Mtoe, 4.9% lower than its 2005 level (33.9 Mtoe). Industry, the largest consumption sector in Belgium, and the residential sector recorded respectively a 0.4 and 1.0 percentage points decrease in their share of total final energy consumption since 2005, reaching 29.9% and 25.8% in 2021. Over the same period, the transport sector increased its share in the Belgian total final energy consumption by 0.7 percentage points to 26.7% and the services sector maintained its share at 13.8%.

Energy efficiency for final consumers improved by an average of 1.3% per year from 2005 to 2021 or 18.3% over the period. This improvement was mainly driven by the industrial sector (27.1% over the period) and the residential sector (23.7% over the period). In transport, energy efficiency improvements have been steady, with an average of 0.4% per year since 2005.

Belgium is a federal state, in which energy efficiency is a competence of the three Regions (Flanders, Wallonia and Brussels-Capital), with supporting measures from the federal government. Within the framework of Art. 4 of the Energy Efficiency Directive (EED) recast (directive (EU) 2023/1791), Belgium has set an indicative energy efficiency target: a primary energy consumption of 36.5 Mtoe in 2030, corresponding to a final energy consumption of 29.9 Mtoe.

Buildings

In 2021, the average consumption per dwelling (with climatic corrections) was 19.3 MWh (1.7 toe). This is a decrease of 20.9% compared to 2005, where the average consumption per dwelling was 24.4 MWh (2.1 toe), an improvement of 0.3 MWh per year on average. The 2020 increase is at least partially attributable to the lockdowns linked to the COVID-19 pandemic. 

Overall residential energy consumption decreased by 6.2% from 2005 to 2021 (an average of 0.4% per year) despite an increase in the number of households and dwellings. The decrease mainly concerns fossil fuels (oil and coal), while consumption of renewables increased by over 300%.

Globally, the final energy consumption of residential buildings was 0.6 Mtoe (6.6 TWh) lower in 2021 than in 2005. Two main factors contributed to increased energy consumption over the period – more dwellings (1.3 Mtoe), and "others" (0.5 Mtoe), which could include various drivers such as the fact that there are more appliances per dwelling or that habits have changed (more intensive use of some appliances for instance). However, energy savings (-2.4 Mtoe) more than offset the effect of the drivers of consumption growth and explain the observed decrease in global energy consumption.

While the energy consumption per employee in the services sector dropped by 23.6% since 2005 (likely driven by a decrease in consumption for space heating), electricity consumption remained quite stable until 2009, before declining slowly until 2019 and more sharply thereafter. This could be explained by the diffusion of IT and electrical appliances in offices, which eventually reached a saturation point and was then offset by increased efficiency. The lockdowns linked to the COVID-19 pandemic and the subsequent generalization of teleworking probably contributed to reducing both consumptions from 2020 on.

The regions have, each for their own territory, mainly implemented the EU Energy Performance of Buildings (EPB) directive, and promoted further energy efficiency through grants, audit schemes, awareness raising, etc. In Brussels, a special effort has also been made to develop exemplary buildings with virtually zero consumption and high environmental quality.

Transport

In Belgium, road transport remains the main driver of energy consumption in domestic transport. Cars represented 49.5% of the total consumption in the sector in 2021, while trucks and light vehicles represented 43.8% (vs 54.6% and 36.7% respectively in 2005). Over the same period, there was a slight decrease in the share of buses (- 0.5%), rail (- 0.2%) and water transport (- 1.2%).

Due mainly to the lockdowns linked to the COVID-19 pandemic, passenger traffic decreased by 12.2% between 2005 and 2021. This decrease was mainly observed in bus traffic (- 47.0%), which saw its share in overall passenger traffic decrease from 13.5% to 8.1%. Car traffic also decreased (- 5.9%), but its share increased (84.9% in 2021 v. 79.2% in 2005). Train traffic decreased (- 15.7%), as well as its share (7.0% in 2021 v. 7.3% in 2005). Between 2005 and 2019, the overall passenger traffic had increased by an average of 0.2% per year (2.8% over the period). Rail traffic and car traffic had increased by 30.5% and 4.5% respectively, while bus traffic had decreased by 21.9%.

Freight traffic increased significantly between 2005 and 2021 (average of 0.6% per year or 9.8% over the period). This increase was mainly observed in road transport (17.1%), while rail transport decreased over the same period (- 16.7%).

Between 2005 and 2021, energy savings (- 0.5 Mtoe) and the decrease in activity (- 0.4 Mtoe) resulting from the COVID-19 pandemic hardly compensated for the consumption increase induced by a modal shift (0.4 Mtoe) and other factors (0.3 Mtoe), such as a decrease in load factors for the freight transport. The modal shift is much higher than previously (0.2 Mtoe between 2005 and 2019 or 0.1 Mtoe between 2005 and 2018).

Each of the three regions has implemented a diversity of measures, covering mobility, infrastructure, promotion of modal shifts and alternative vehicles, as well as unit consumption of vehicles.

Industry

The energy consumption of industry decreased by 6.2% to 9.7 Mtoe between 2005 and 2021. In 2021, the main consumption sectors were chemicals (33.9%), non-metallic minerals (14.1%) and steel (10.2%). The evolution of the consumption in these sectors is however dramatically different, with respectively + 9.1%, - 9.0% and - 39.9% compared to 2005.

Despite the economic crisis of 2007 and the COVID-19 pandemic, industrial activity in Belgium rose overall since 2005. Energy consumption decreased from 2002, but rose again in 2010 and remained relatively stable afterward. Between 2005 and 2021, energy savings (- 4.0 Mtoe) more than compensated for the rise in all the other drivers of the energy consumption variation, and especially in activity (3.3 Mtoe). As can be seen on figure 2, the energy efficiency improvements in the industrial sector accelerated from 2019 on.

In Belgium, the energy efficiency policy in industry focuses on voluntary agreements between the regional governments (of Flanders and Wallonia) and industry. The ways of setting the targets and monitoring the results differ between the regions and have changed over time.
