Basel on its way to the 2000-Watt-Society

Energy demand and renewable potentials need to be synchronized in time and space. Energy has to be provided at the right place at the time of demand and in the quantity needed. This means, that a spatial model of the region has to be elaborated that is based on a geographic information system (GIS) and linked to an expert system (a spreadsheet). The Space Type Energy Model (STEM) developed is such a GIS-based expert system. For the Canton of Basel-City it was applied to model the demand-supply structure for a 2000-Watt- scenario. It was also used to access the capacity of Basel-Stadt to become energetically self- sufficient. In addition, greenhouse gas emissions as well as CO2-reduction potentials were mapped. Finally, investments and savings associated with the introduction of renewable energy options were assessed.
