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. (C) 2016 The Authors.
