Iran with considerable amount of oil and gas resources is one of the exporters of primary energy. However, during the past th ree decades, due to the ongoing process of social and economical developments, revising the present strategy of utilizing energy resources in the country is largely met through imports. Iran is potentially one of the best regions for utilization of most alternative sources of renewable energies. The aim of this study is to propose a Fuzzy multi-criteria decision-making approach (FMCDM) in order to evaluate 4 alternative renewable energies (solar, geothermal, hydropower and wind energies) in Yazd province in Iran. Two FMCDM methods are proposed for this problem: Fuzzy Analytic Hierarchy Process (FAHP) is applied to determine the relative weights of the evaluation criteria and the extension of the Fuzzy TOPSIS is applied to rank the alternatives. Results indicate that solar energy is the most appropriate renewable energy source for the studied area.
