Abstract

The decision-making process regarding the choice of alternative energy is multidimensional, made up of a number of aspects at different levels—economic, technical, environmental, and social. In this respect multicriteria analysis appears to be the most appropriate tool to understand all the different perspectives involved and to support those concerned with the decision making process by creating a set of relationships between the various alternatives. The main aim of this paper is to make a preliminary assessment regarding the feasibility of installing some wind energy turbines in a site on the island of Salina (Aeolian islands—Italy). Thus, a multicriteria method will be applied in order to support the selection and evaluation of one or more of the solutions proposed. Having analysed the local environmental conditions and its energy profile, four wind turbine configurations were postulated as options. These options were then appraised by comparison against a family of criteria and calculations were performed using a multicriteria algorithm to rank the solutions, from the best to worst. The option at the top of the ranking refers to the installation of a plant of 150kW and this emerged as the right compromise between the costs of realization, local energy requirements and the need to conserve the area and the environment especially in view of the high/medium-bracket tourism business on the island. The sensitivity analysis performed subsequently backed up the findings. As this work demonstrates, multicriteria analysis can provide a valid tool to aid decision making for achieving targets relating to more sustainable green energy.
