Depending on the technology used, electricity from renewable energies can be produced significantly cheaper than electricity generated in conventional power plants. This is shown by a study by the Fraunhofer Institute for Solar Energy Systems ISE. Accordingly, electricity from gas turbines and hard coal-fired power plants is the most expensive to produce.

Photovoltaic systems convert solar radiation into electrical energy using solar cells. In a global comparison, Germany was recently one of the leading countries, along with China, the USA and Japan, in the use of photovoltaics to generate electricity.

In Germany, the installed capacity of photovoltaic systems increased continuously. In 2020, photovoltaic systems with an output of around 54 gigawatts were installed in Germany. The electricity generated by this amounted to around 51 terawatt hours of electricity in the same year. The largest capacities for generating solar power are in the south of Germany. Bavaria is currently by far the federal state with the largest capacities, followed by Baden-Württemberg.

▶️ Solar park in Bürstadt on 13 hectares: Conflict between agriculture and the energy transition – Agri-PV as a compromise?
A new 13-hectare solar park in Bürstadt is sparking debates about climate protection and land use. Farmers see their land threatened and fear for crop yields and traditional businesses. Proponents emphasize the importance of renewable energies for the energy transition and regional power supply. Agri-PV is presented as a possible compromise that allows simultaneous agriculture and power generation. Acceptance depends on fair leasing models, community participation, and transparent processes. Economic opportunities for farmers through additional income are in addition to investment and maintenance costs. Ecological aspects such as biodiversity, pollinator protection, and soil quality determine the sustainability balance. Policymakers and planners must create clear guidelines to resolve conflicting objectives legally and socially. Locally led pilot projects and scientific monitoring can demonstrate practical solutions. The Bürstadt case demonstrates the importance of dialogue-oriented solutions for combining climate goals and rural development. [...]
