Developing Sustainable Energy Systems on Croatian Islands

Today, islands represent excellent places for demonstration of new clean technologies and new pathways for sustainable development. Islands in their nature are isolated systems so to organize life on them they usually have all elements of the big system but just operated on a smaller scale. The advantage of the islands is that they have favourable potential of renewable energy sources and they are not so rich in fossil fuels thus a lot of them are 100% dependent of imports. Small islands’ markets and large imports of fuels that cannot be stored locally, due restricted space and capacity of local storages, make fossil fuels even more expensive. Here RES and storage technologies are competitive to fossil fuels even without subsides. Of course that competiveness in the first place depends on RES potential and cost of selected conversion and storage technologies but there are some islands in the world that manage to find financial models that allowed them to reach 100% RES electricity supply and almost 100% of heat supply. Sustainable action plans and development scenarios for dozen of Croatian Islands are described in the paper (Unije, Cres, Losinj, Krk, Hvar, Korčula, Lastovo, Mljet, and Hvar). Evaluation of costs, environmental impact and possible creation of jobs is assessed separately for evaluated scenarios. The work also includes examples of some applied projects.
