TECHNICAL POTENTIALS OF A BIOENERGY PRODUCTION IN A BUNDESLAND IN THE FEDERAL-REPUBLIC-OF-GERMANY

The objective of this paper is to analyze the technical potentials of an energy production from biomass. Thus, for every community in Baden-Wurttemberg, a state in the south-west of the Federal Republic of Germany, the corresponding energy potentials of this renewable sources of energy are calculated. The investigation is divided into two parts. In both parts the methodological approach to determine the technical potentials is presented first. Part one deals with the energy potentials of residues from forestry and farming. This shows that in Baden-Wurttemberg an energy potential exists of about 13,745 TJ/a from residual wood, of approximately 3610 TJ/a from energetic usable straw and of about 13,690 TJ/a from biogas. In part two the direct production of energy carriers on agricultural land is analysed. Hence an energy potential could produce between 10,370 and 25,858 TJ/a from plants for using as a solid energy carrier and between 8772 and 17,673 TJ/a from plants to be converted into plant oil or alcohol. The results are evaluated on a high spatial resolution and analysed taking the local differences into account. Finally, the calculated potentials are discussed with respect to the energy demand in the current energy system.
