GIS tools for renewable energy modelling

In contrast to conventional energy modeling made on a national basis, we consider energy use and supply per unit of land area. This is particularly suited for dealing with dispersed energy resources such as renewable energy, and by making the match of demand with supply on this basis in a geographical information system (GIS), we are able to directly identify any mismatch entailing needs for energy trade and establishment of energy exchange facilities (power grids, gas distribution lines, etc.). The model is being applied to several global energy scenarios and constitutes a quite general tool for system modeling, assessment and planning.
