From global to local level in the world, all policy makers and strategic authorities are aware of the superiorities of renewable energy. Hence, there are enormous studies, action/master plans and researches about significance of renewable energy have been conducted to meet growing energy demand with green energy sources in a long term. Renewable energy potential of Turkey provides an advantage due to the climatic conditions. In this study, a nonparametric method and powerful benchmarking tool, Data Envelopment Analysis (DEA) has been utilized in order to analyze the renewable energy efficiencies of the each provinces (81 cities) in Turkey. According to the obtained results, investment decisions should be applied particularly, in inefficient regions to provide overall technical efficiency for future.
