From Wikipedia (Bioenergy Village)
A bio-energy village is a regionally-oriented concept for the use of renewable energy sources in rural areas. The system uses biomass from local agriculture and forestry in a biogas powerplant to supply the complete energy demands of a village, as electricity and district heating.
These villages tend to be self-powered and independent from external grids, despite being connected to overland grids for feeding surplus energy. The term “bio-energy village” describes only the energy dependency on fresh biologic material, whereas an “ecovillage” includes more differentiated networks.
Examples of such villages are Jühnde near Göttingen and Mauenheim near Tuttlingen in Germany.
