In 2025, Luxembourg's electricity consumption is heavily reliant on imports, which account for more than 70% of its supply. This means that almost three-quarters of its electricity demand is met by external sources. Low-carbon energy plays a significant role in the domestic electricity mix, contributing over a quarter of Luxembourg’s electricity, with wind power making up nearly 10%, solar power almost 9%, biofuels around 7%, and hydropower about 1.5%. Fossil energy, mainly gas, is minimal, contributing just over 1%, reflecting a positive trend towards cleaner energy sources.

Is Electricity Growing in Luxembourg?
Electricity consumption is on a downward trend in Luxembourg, which is concerning given the global need for more energy to support electrification and technological growth. In 2025, the per capita consumption stands at 7041 kWh, significantly lower by 10007 kWh than the peak in 2010. Alarming is also the decrease in per capita low-carbon electricity generation, which dropped from 3846 kWh in 2024 to 1877 kWh in 2025. This sizeable reduction underscores the urgent necessity for Luxembourg to enhance its investment in clean energy to meet future energy needs sustainably.
Suggestions
To boost low-carbon electricity, Luxembourg could draw inspiration from regions that successfully utilize solar and nuclear energy. France is a leading example with 70% of its electricity sourced from nuclear energy, and Nevada is notable for its 33% contribution from solar. By embracing similar strategies, Luxembourg can reduce its dependency on imports and fossil fuels while simultaneously addressing climate change and pollution. A strategic focus on expanding nuclear and solar capacity would align with Luxembourg’s commitment to a sustainable future and better prepare it for increasing electricity demands.
History
Historically, the development of low-carbon electricity in Luxembourg saw various changes, particularly with hydropower. In the early 1990s, hydropower witnessed minor fluctuations, with notable increases in 1990 and 1994, followed by several modest reductions. A significant drop occurred in 1999, yet a resurgence came in 2010 with a sizeable increase. The 2010s featured mixed trends, but the significant decline in hydropower in 2025 by 1.3 TWh indicates a persistent volatility. Newer low-carbon sources like wind and solar started to emerge more prominently from 2017 onwards, with wind increasing in 2023 and solar contributing in 2024. Despite these positive advancements, the substantial decrease in hydro electricity must serve as a catalyst for investing in more stable clean energy sources like nuclear or solar to ensure a resilient and sustainable electricity future for Luxembourg.
