Lörrach on the way to climate neutrality: 1900 solar systems active!
Lörrach is aiming for climate neutrality by 2040 and operates over 1,900 photovoltaic systems to promote renewable energies.
Lörrach on the way to climate neutrality: 1900 solar systems active!
A lot is happening in the city of Lörrach when it comes to climate protection. Over 1,900 photovoltaic systems are already in operation, and the goal is clear: the city should become climate neutral by 2040. Schwarzwälder Bote reports from a total of 1933 Photovoltaic systems installed at the end of 2024 with an impressive gross output of 19,960 kWp. What is particularly exciting is the fact that most of the systems can be found on house roofs.
A look at current developments shows that the city also operates its own PV systems, the total capacity of which is around 239 kWp. The city marketing has done a great job here - from the museum depot in Brombach to the gymnasium of the Fridolinschule and the Hebelgymnasium, where the newest facility has been running since January 2025.
Advances in solar energy
The city administration is pursuing a model of roof leasing to external investors. This helps with the planning, construction and operation of the PV systems. Most of the electricity generated is used directly in the respective building. The possibility of installing PV is always examined for new buildings and roof renovations. There are currently several projects on the agenda - including the planned Haagen daycare center and roofs at the Tumringen elementary school and the Schlossberghalle. The cemetery company is also planning a PV system with storage for the crematorium.
It is important to the municipal utilities to check the PV suitability of the waterworks at Grütt, while small PV systems at four retention basins are also being considered by the company's own wastewater operation. However, there are also challenges: Some buildings are not suitable for PV installations due to monument protection, shading or static reasons. Mayor Monika Neuhöfer-Avdić therefore emphasizes the systematic examination of all new construction and renovation measures for potential for photovoltaics.
Climate neutrality in the automotive industry
But skill in climate protection is not only demonstrated in Lörrach. The automotive industry has also set out and is pursuing ambitious climate neutrality goals. The BMW Group, for example, relies on a holistic approach that covers the entire life cycle of a vehicle. According to Sustainable Switzerland, the BMW Group aims to reduce CO₂ emissions in its value chain by 40% by 2030 compared to 2019 - which corresponds to around 200 million tonnes of CO₂.
An important element here is the electrification of the vehicle range. Electric vehicles emit almost no CO₂ during operation, and CO₂ emissions can be further reduced by using electricity from renewable sources. Initiatives to reduce CO₂ take place at various locations. One example is the partial electrification of delivery traffic in Regensburg, where up to 94 tons of CO₂ were saved per year.
The progress is also supported by innovative projects, such as testing wind turbines without visible moving parts at BMW locations. A technology is used here that generates clean electricity through a vacuum effect. These measures are just the beginning of the long road to a sustainable future.
