Decision making in energy planning. Application of the Electre Method at regional level for the diffusion of renewable energy technology

The authors show an application of the multicriteria decision-making methodology used toassess an action plan for the diffusion of renewable energy technologies at regional scale. Thismethodological tool gives the decision-maker considerable help in the selection of the mostsuitable innovative technologies in the energy sector, according to preliminary fixed objectives.In this paper, a case study is carried out for the island of Sardinia. This region presents, onone hand, a high potential for energy resources exploitation, but on the other hand, it representsa specific case among other Italian regions, because of its socio-economic status and history.Three decision scenarios have been supposed, each one representing a coherent set ofactions, on the basis of which strategies of diffusion are developed.
