From October 2025 through September 2026, Luxembourg relied on net imports for about 61% of its electricity consumption. Domestic low-carbon generation supplied roughly 37%, while fossil generation accounted for less than 2%. Hydropower contributed 15%, solar almost 10%, wind about 9%, and biofuels around 4%. Imports therefore supplied more than half of the electricity consumed, but the data do not identify their generation sources, so they cannot be classified here as either low-carbon or fossil electricity.

Is Electricity Growing in Luxembourg?

The latest figures do not show Luxembourg reaching new electricity highs. Electricity consumption in 2026 was about 8,300 kWh per person, roughly 8,700 kWh below the 2010 record of around 17,000 kWh—almost a halving. Low-carbon electricity generation stood at about 3,100 kWh per person, around 750 kWh, or 19%, below its 2024 peak. These comparisons show a substantial retreat from previous records, although they do not establish the latest year-on-year trend. The decline in clean electricity generation is concerning as electrification and growing digital demand call for more low-carbon electricity.

Suggestions

Luxembourg can increase clean electricity generation by accelerating solar deployment on rooftops, commercial buildings and suitable developed land, while expanding wind generation where appropriate. Nearby Germany offers a relevant example, generating about 20% of its electricity from solar and 31% from wind; the Netherlands generates a quarter from wind. Hungary also demonstrates solar’s potential, with a share of about 23%. Nuclear should be part of Luxembourg’s long-term planning, including consideration of domestic generation and participation in regional nuclear projects. Neighbouring France generates about two-thirds of its electricity from nuclear, while Slovakia achieves a similar share, illustrating how nuclear can provide a strong foundation for a low-carbon electricity system. Regional partnerships could strengthen clean electricity supply, while domestic solar, wind and potentially nuclear would increase Luxembourg’s own generation.

History

Luxembourg’s recorded low-carbon electricity history has been dominated by hydropower fluctuations, followed more recently by gains in wind and solar. Hydro generation rose by 0.8 TWh in 1990, then experienced several smaller increases and declines throughout the 1990s. Modest gains in 2000 and 2002 preceded a 0.1 TWh decline in 2009. The 2010s brought hydro increases of 0.6 TWh in 2010 and 0.4 TWh in 2015, but declines of 0.3 TWh in 2011 and 0.4 TWh in 2019; wind added 0.1 TWh in 2017. In the 2020s, hydro and biofuels each gained 0.1 TWh in 2020, wind added 0.2 TWh in 2023, and solar added 0.2 TWh in 2024, while biofuels fell by 0.1 TWh in 2023. The 0.6 TWh hydro decline in 2025 was a substantial setback, reinforcing the importance of sustained expansion across clean electricity sources.
