Sustainable Combination of Bifacial Solar Modules, Wind Energy and Biomass While Simultaneously Utilizing Agricultural Land and Increasing Biodiversity.


The project "sustainable combination of bifacial solar modules, wind energy and biomass while simultaneously utizilizing agricultural land and increasing biodiversity", abbreviated as BiWiBi addresses various social challenges simultaneously:

  • The development of market-based business models for renewable energy
  • The competition between energy and food production for land
  • And the extinction of species, especially pollinators

A new concept of land use in rural areas is created by a joint use and an energetic management of flower strips.


Project description

The aim of this publicly funded, one year project is to collect and answer interdisciplinary questions relating to the overall concept. For this reason, the project partners are pooling together their expertise.


Fraunhofer IMW Leipzig is researching the economic viability and possible business models. The DBFZ German Biomass Research Center is investigating agricultural use, the Saxony-Anhalt Cultural Landscape Foundation is researching the ecological aspects while the Helmholtz Centre for Environmental Research UFZ the acceptance skeptics.

Next2Sun and Terrawatt Planungsgesellschaft support the project as associated partners with their expertise for solar and wind power plants. The Krauscha estate in Lusatia advises the project with practical know-how from ecological agriculture.
