From September 2025 through August 2026, Luxembourg relied on net imports for almost two-thirds of its electricity consumption. Domestic low-carbon generation supplied about 36%: hydropower contributed 14%, solar and wind about 9% each, and biofuels roughly 4%. Domestic fossil generation accounted for less than 2%. These figures show that clean electricity dominates domestic generation, but imports remain the largest source of electricity supply; the data do not identify the low-carbon or fossil composition of those imports.

Is Electricity Growing in Luxembourg?

The latest figures do not show Luxembourg setting new electricity consumption or clean-generation records. Electricity consumption in 2026 was about 8,350 kWh per person, roughly 8,700 kWh below the 2010 record of about 17,050 kWh—around a 51% decline from that peak. Low-carbon electricity generation was about 2,985 kWh per person, approximately 880 kWh, or 23%, below its 2024 record. These comparisons do not establish the latest year-on-year trend, but the substantial gaps from previous highs are concerning as electrification and AI create additional electricity demand.

Suggestions

Luxembourg can increase clean electricity generation by accelerating rooftop and other suitable solar installations, expanding wind generation, and considering nuclear development or participation in regional nuclear projects. Nearby regions offer useful examples: solar supplies about 20% of electricity generation in Germany and 19% in the Netherlands, while wind contributes about 31% in Germany and 25% in the Netherlands. France generates roughly two-thirds of its electricity from nuclear power, and Slovakia achieves a similar share, demonstrating nuclear’s potential to supply substantial low-carbon electricity. Luxembourg could learn from these examples through faster project delivery, stronger grid connections, and cross-border cooperation, combining domestic solar and wind expansion with nuclear investment.

History

Luxembourg’s low-carbon electricity history has been marked by sizeable hydropower fluctuations alongside more recent wind and solar growth. Hydropower generation rose by 0.8 TWh in 1990; subsequent gains and declines included increases of 0.2 TWh in both 1994 and 1995, followed by a 0.3 TWh fall in 1999. The 2000s brought smaller changes, while the 2010s saw hydro gains of 0.6 TWh in 2010 and 0.4 TWh in 2015, offset by declines of 0.3 TWh in 2011 and 0.4 TWh in 2019. Wind added 0.1 TWh in 2017 and another 0.2 TWh in 2023, while solar added 0.2 TWh in 2024—welcome steps toward a broader clean electricity supply. Biofuels increased by 0.1 TWh in 2020 and decreased by the same amount in 2023. The large 0.6 TWh hydropower decline in 2025 is concerning and reinforces the need for sustained expansion of low-carbon generation.
