Geodata can help in the expansion of renewable energies and thus in the acceleration of the energy transition. The Reiner Lemoine Institute (RLI) is now publishing a comprehensive data package with potential areas for Germany. This helps to find suitable areas for photovoltaic (PV) and wind power plants. For the first time, the data is available for free use under an open license on the online storage service Zenodo. RLI scientists compiled and prepared the geoinformation for the digital application PV and Wind Area Calculator of the think tank Agora Energiewende. The tool was published in October 2021.
