Advanced RenewIslands method with quantitative mapping of islands' needs and resources

RenewIslands is a method that is used for energy planning of the islands. The method creates several alternative scenarios of energy planning with respect to island needs and resources. Although it provides general directions in which islands should plan their energy infrastructure, RenewIslands scenarios and results are based on qualitative data. Because of this, the proposed alternative scenarios cannot be considered with sufficient accuracy. This paper's aim is to propose a new way of assessing island needs and resources and therefore proposing an advanced RenewIslands method. New quantitative indexed indicators are created with indexation method presented in this paper for determining islands need for electric energy, heat, cold, water, waste and wastewater treatment as well as islands local energy resources, energy infrastructure and water resources. Mathematical calculations of indicators are presented in this paper. The necessary data for indicator calculation was obtained from available Sustainable Energy Action Plans, Strategy Plans, Reports from utility companies, Waste Management Plans and other relevant documents and research. Precisely calculated indicators of islands' resources and needs enable much more accurate estimation of optimal energy flows integration. Developed indicators are applied to 11 islands in the Adriatic Sea and normalized based on the Min – Max method. The normalized indicators are summarized in composite RenewIslands index RIS, ranked and compared to the average score. Indicators are also compared with the qualitative results of resources and needs mapping of islands Mljet, Vis, Lošinj, Krk, Lastovo, Korčula and Unije. The comparison shows that there is a significant difference between the indexed results and the results obtained by qualitative assessment. Developed indicators clearly show which islands have the best resources and greatest needs for implementing advanced technology and therefore show which islands have the best opportunities and greatest need for creating self – sufficient sustainable environment.
