The energy transition is no longer a theoretical prospect. In Luxembourg, it is becoming the norm, driven by figures that reflect a gradual shift. In three years, more than 80,000 solar panels have been installed, a sign of massive interest in local electricity generation. This trend, supported by government subsidies, is gradually reshaping the country’s energy landscape.
The Klima-Agence, which published its 2025 annual report on Thursday 23 April, claims a pivotal role in this transformation. The agency emphasises the economic dimension of this shift. Reducing dependence on fossil fuels, stabilising costs in the long term, and improving the region’s resilience: the arguments put forward relate as much to strategy as they do to environmental concerns.
On the ground, the growth is clearly evident. In 2025, more than 16,000 interactions were recorded with individuals, businesses and local authorities. This presence reflects a growing demand for support in dealing with increasingly complex technical and financial decisions.
Up to 70% energy savings
The issue goes far beyond solar power alone. Electric mobility, heat pumps and energy-efficient refurbishment are emerging as complementary solutions. A comprehensive refurbishment can reduce a home’s energy consumption by up to 70%, whilst home charging can significantly cut the costs associated with using an electric vehicle.
Against this backdrop, the agency is relying on a new tool to overcome these obstacles. Following on from the subsidy simulator already in place, the Klima-Agence also launched the solar simulator on Thursday 23 April, which allows users to estimate electricity generation, self-consumption levels and the associated financial benefits by entering a few details about their home and energy consumption. The aim is to make a technical project easier to understand and to help speed up decision-making.
For businesses, the transition is also becoming a matter of competitiveness. The ‘Klimapakt fir Betriber’ programme sets out a framework for decarbonisation initiatives aimed at both reducing emissions and optimising energy costs. Electricity sharing and self-consumption of solar power are highlighted as concrete solutions for improving economic performance. The Klima-Agence now plays a central role in this ecosystem. “The Klima-Agence continues to strengthen its role as an advisor, facilitator and supporter serving Luxembourg,” emphasises its director,
