In recent decades, due to the increase in the urban population and the unbridled growth of urbanization, many efforts have been made to create livable cities by emphasizing the place of renewable energy in the sustainable transportation sector. Using clean, renewable, and sustainable energy resources is needed to improve social, economic, and environmental health, leading to economic development and productivity. This research tries to clarify the importance of using renewable energy in the transportation sector. In this regard, the main goal of this research is to identify effective indicators and sustainable solutions with an emphasis on the use of renewable energy in the urban transportation sector. Also, in this research, an attempt has been made to answer the questions raised by carefully examining the existing studies based on the scoping review method. The findings show that the extracted influential indicators can be categorized into environmental, economic, and social indicators, which have a significant impact on the use of renewable energy in the transportation sector. Paying attention to this index can increase the amount of use of renewable energy and the amount of desirability of the effective use of urban transportation. Finally, suggestions for strengthening sustainable development in urban transportation systems with an emphasis on the use of renewable energy have been presented.

The trend of the fourth industrial revolution in the field of energy, like other sectors, indicates that the path of production, development and approaches to energy use in the world is changing every day. This change can be seen in the growth of new energy production in developed countries by renewable energy. Owing to the global energy crisis all around the world and the exhaustible non-renewable energy resources, as well as increasing the pollution and green supply chain due to the indiscriminate use of fossil fuels, the need to use sustainable energy, especially In the industrial sector, which accounts for 40% of energy consumption in our country, has been paid attention to. The present study developed and prioritized green supply chain strategies with uncertainty over time under fuzzy conditions in Mobarakeh Steel Company. First, the internal strengths, weaknesses, opportunities, and threats were identified based on theoretical foundations and experts’ opinion. Then, the green supply chain strategies of Mobarakeh Steel Company were developed using the SWOT method. Fuzzy ANP method was used for weighing the dimensions of sustainability while the TOPSIS and TODIM methods were used for weighing the strategies. The results indicated that among the indicators of sustainability, "social" indicator had the first rank, "environmental" indicator had the second rank, and "economic" indicator had the third rank. In addition, SO strategies had the first rank, ST strategies had the second rank, WO strategies had the third rank, WT strategies had the fourth rank.

During the last decade, serious issues such as energy demand, depletion of fossil fuels and their environmental impacts draw attention towards renewable energy sources. In addition, the energy supply chain of Iran is deeply reliant upon fossil fuels. Further obstacles such as electricity blackouts in the hot season and future energy security require us to address these issues. For this reason, the growing consensus is to dominate a sustainable energy system on the grounds of energy, especially renewable energies, with low emission and pollution. The mean annual solar radiation in Iran is 2200 kWh/m2 which is greater than the worldwide average, due to locating on the world's Sun Belt. The total installed capacity of solar energy in Iran is not significant, however, it is growing annually. .Moreover, the Persian Gulf coasts, could provide the possibility of using the tidal energy of the ocean as well as the Caspian Sea coast which are suitable sites for thermal energy. Currently, 550 MW of renewable energy is being built in Iran and the installed capacity of renewable energy has reached 575 MW. Renewable energy has also led to the employment of 47,321 people directly and indirectly in the country. The installed capacity of Iran’s wind power is about 259 MW (45% of total renewable energies installed capacity), which is mostly located in Manjil and Roodbar. The biogas energy in Iran is mainly produced from domestic and industrial sewage/waste, animal waste, and agricultural product waste.
