An Economic Approach to Choose the Energy Mix for Small Islands. A Case Study in the Mediterranean Sea

Renewable energies are essential for the clean energy transition needed to achieve the objectives of the European Green Deal and reduce the dependence on fossil fuels and the energy imports. In the recent years, new increasingly stringent laws on polluting emissions and the need to lower production costs promoted greatly the technological progress in the field of renewable energies. However, in various remote areas and small islands the production of energy it is still dominated by the use of fossil fuels. This paper discusses the feasibility of a mixed system of renewable sources (wind, photovoltaic and sea wave energy) to be implemented in the Aeolian Islands, using the minimization of the Levelized Cost of Energy as a criterium.
