In 2024, Belgium's electricity landscape is predominantly low-carbon, accounting for over two-thirds of the total production. The largest contributor to this is nuclear energy, which alone forms slightly more than a third of the country's electricity generation. Wind power significantly contributes as well, making up just over 15%. Solar energy also plays a vital role, representing roughly 10% of electricity generation. In contrast, fossil fuels, primarily gas, provide less than 14% of electricity, indicating a shift towards cleaner energy sources. Although net imports account for about 10.5%, they can be supplied from both low-carbon and fossil sources, depending on regional agreements. Biofuels and hydropower, contributing 3.45% and 3.26% respectively, complete the picture of Belgium's current electricity consumption profile.
To further increase low-carbon electricity generation, Belgium should consider expanding its nuclear, wind, and solar capacities, both of which have proven effective domestically and internationally. Countries like France, where 68% of electricity is generated from nuclear power, demonstrate the potential longevity and reliability of nuclear energy. Similarly, Denmark sets an exemplary standard for wind energy, with 59% of its electricity sourced from wind, which could serve as a model for Belgium to enhance its wind generation capabilities. Solar power also presents a growth opportunity; Belgium might look towards Greece and Chile, where solar contributes approximately 22% to their electricity generation, as guiding examples in scaling up this green energy source.
Looking back at Belgium's electricity history, nuclear power's evolution is notable, with substantial positive gains in output during the mid-1970s and subsequent spurts of growth in the mid-1980s and late 1990s, marking periods of expansion and reliability. However, this trend has been marred by significant declines, particularly in the 2010s, where reductions became alarmingly frequent, culminating in substantial cutbacks in recent years. Such sporadic declines, notably highlighted in 2012, 2014, and 2018, emphasize the need for consistent policy support and investment in nuclear energy, ensuring that it can reliably shoulder the responsibility of serving as a crucial low-carbon energy source. Meanwhile, wind energy has been gaining momentum in the past few years, aligned with the trend towards increasing adoption and scalability to complement nuclear and solar power. As Belgium continues to advance in its electricity generation capabilities, focusing on these sustainable green solutions will be vital for reducing dependence on fossil fuels and mitigating climate change impacts.
