V. Daniil, Investigation of renewable energy sourses use, to the non connected island of Astypalaia, Diploma thesis, 112 pages, March 2018.
Most of the Aegean islands are not connected to the electricity network of the mainland. The production of electric energy relies on local oil fuel plants, which have high cost due to import of oil, compared to the import and distribution cost in the mainland. Apart from the high cost, it has to be taken into consideration the environmental pollution from the oil fuel use, because during the last years serious efforts have been made for the reduction of oil fuels in energy production. For this study the selected area is the remote island of Astypalaia, which is part of Dodecanese and has population of 1.334 inhabitants. The purpose is to investigate all the renewable energy resources, which can be used in the island for electric energy production like wind, solar, hydropower, biomass, marine and geothermal energy, in order to be examined in which percentage can be used in the energy mix. Special emphasis has been given to biomass and specifically in the use of agricultural residues for energy production, but also in the cultivation of energy crops. Finally, some cases were examined where combined renewable resources were used to cover percentage of the energy demand, aiming at the decrease of oil fuel use in electric energy production.
