Funding research and development (R&D) in renewable energies is intended to generate new technologies and applications and contribute to renewable energies being used in the long term on a large scale and at low costs. This means that R&D has major influence on the long-term assessment of the economic efficiency of renewable energies in a system comparison. At the same time, however, R&D in the field of renewable energies is closely linked to noticeable distributional effects (burdens and relief). These are determined and presented differentiated by actor group.
On a federal level, several ministries provide R&D funding for renewable energies. These include the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU), the Federal Ministry of Education and Research (BMBF), the Federal Ministry of Economics and Technology (BMWi) and the Federal Ministry for Food, Agriculture and Consumer Protection (BMELV). A distinction must be made between project funding and institutional funding. The distributional effects are to be investigated in detail, particularly for the area of project funding by the BMU.
