In today's world, megacities face numerous challenges, including air pollution, climate change, and dependence on fossil fuel resources, as they serve as primary economic and social centers. These challenges not only impact the quality of life for citizens but also harm environmental sustainability. In this context, the use of renewable energy has been proposed as a sustainable and effective solution to mitigate the negative effects of these issues and achieve sustainable development in urban areas. The metropolitan area of Tehran, in particular, is confronted with environmental challenges, energy supply issues, and air pollution. Therefore, focusing on the use of renewable energy, especially considering the potentials of Tehran as a megacity, is crucial. The aim of this research is to assess the feasibility of utilizing renewable energy resources for sustainable development in the metropolitan area of Tehran based on existing potentials. This study employs an analytical-descriptive method, utilizing library research, document analysis, questionnaires, maps (GIS), and qualitative content analysis. For data analysis, the study applies content analysis, expert questionnaires, the Analytical Hierarchy Process (AHP) for weighting criteria, and the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) for ranking renewable energies. Energy modeling is conducted using the HOMER software. According to the research findings, wind and solar energies were highlighted based on the potential of the metropolitan area of Tehran through feasibility analyses using GIS maps. Additionally, to conduct a more precise analysis, expert questionnaires were used to identify the best renewable energy sources, with solar and wind energy being ranked based on the AHP and TOPSIS methods, respectively, considering the potentials of Tehran. Thus, energy modeling using HOMER was employed to assess the feasibility of renewable energy utilization based on renewable energy usage indicators and energy consumption and production levels. The energy modeling revealed four alternatives, among which the fourth alternative, representing a hybrid system of renewable energies and diesel, was selected. The findings indicate that Tehran, given its renewable energy potentials, holds a very promising position, and the utilization of these energies can lead to energy savings, pollutant reduction, global warming mitigation, economic growth, job creation, and more. Therefore, the adoption of renewable energy in the metropolitan area of Tehran can enhance sustainable development and help achieve sustainable development goals.
