In 2025, Belgium's electricity consumption showcases a significant contribution from low-carbon sources, with more than 60% of its electricity generated from clean energy. Nuclear power stands out, contributing almost a third to the electricity mix, cementing its role as a key player in the country's low-carbon strategy. Wind and solar energy also play substantial roles, accounting for nearly 16% and over 13% respectively, signaling a strong commitment to sustainable energy sources. Gas, a fossil fuel, makes up a little over 16%, showing that while there is still reliance on fossil fuels, Belgium is progressing towards a greener future. Net imports form almost 12% of the electricity supply, highlighting Belgium's interconnectedness with its neighbors. Additionally, smaller contributions come from biofuels and hydropower.

Is Electricity Growing in Belgium?
The trends in electricity consumption reveal a worrying decline in Belgium. The current average consumption, at 6614 kWh per person, is noticeably reduced by nearly 2500 kWh compared to the 2006 peak. This decline is mirrored in low-carbon generation, which fell from the record-high levels of 2021, decreasing by about 1900 kWh per person. The decrease is concerning given the growing global need for increased electricity to support electrification and technological innovations. To keep pace with future demands, Belgium must prioritize the ramp-up of low-carbon electricity generation.
Suggestions
To boost low-carbon electricity, Belgium should consider expanding its existing nuclear, wind, and solar infrastructure. Regions like France and Slovakia, with high percentages of nuclear generation, serve as examples of maximizing nuclear power. Meanwhile, countries like Denmark and states like Iowa showcase the potential of wind energy. Additionally, regions such as Nevada and California demonstrate successful solar energy strategies. By adopting strategies from these regions, Belgium can enhance its green electricity output, ensuring that it meets future demands sustainably and effectively combats climate change and air pollution associated with fossil fuels.
History
The history of low-carbon electricity in Belgium shows significant fluctuations in nuclear power generation. The late 20th century, specifically between the mid-1970s and 1990s, witnessed consistent growth in nuclear energy, with substantial increments in several years. However, the early 2010s marked a period of significant reductions in nuclear generation, raising concerns about the country's commitment to maintaining a clean-energy trajectory. More recently, variable growth with sharp increases in some years and declines in others underscores the necessity for a stable and sustained approach to nuclear energy, alongside a ramp-up in wind energy as seen in 2023. Belgium must aim for consistent expansion rather than periodic fluctuations to ensure a steady supply of low-carbon electricity.
