This qualitative study investigated the impact of utilizing renewable energy sources in football stadiums. The research focused on experts in sustainable development, stadium managers, and technical engineers involved in the Iranian Football Premier League from 2019 to 2020. Data analysis was conducted using qualitative content analysis methods. Research participants were selected through purposeful and snowball sampling methods, ultimately leading to 12 interviews that reached theoretical saturation. The analysis resulted in 44 open codes, which were further categorized into three key concepts: environmental management, improving the social and cultural situation, and enhancing the economic status. These categories encompassed areas such as reducing environmental risks, managing energy resources and pollution, improving social attitudes and welfare services, urban beautification, reducing organizational costs, promoting the stadium's brand, and generating income. Given global environmental crises and the impact of sports on the environment, it is recommended that government officials, policymakers, and sports managers support the utilization of renewable energy sources like solar and wind energy in football stadiums. These actions are necessary for sustainable development and carbon-free sports.

Today, energy demand has increased as a result of population growth around the world. Due to the limited fossil energy resources and the problems caused by greenhouse gas emissions, it is necessary to pay more attention to renewable energy, because in this way, the goals of sustainable development can be achieved. Therefore, the purpose of this study is to properly evaluate the performance of renewable energy technologies and also to investigate the relationship between renewable energy, carbon dioxide emissions, and sustainable development in Iran and compare it with non-renewable energy. In order to rank renewable energy carriers and identify the best type of them for electricity generation in Iran, a multi-criteria decision model has been used. In this regard, by conducting library studies and collecting the opinions of experts, a set of criteria in the form of four technical, economic, social, and environmental dimensions has been determined. Then, using the VIKOR approach, renewable energies consisting of wind, hydropower, solar, biomass, and geothermal energies are discussed. Findings indicate a high priority of wind energy and solar, hydropower, geothermal and biomass are in the next ranks. The results indicate that the effect of positive momentum on the share of renewable and non-renewable energy on sustainable development in Iran is positive.

Due to the increasing use of storage as one of the effective methods for peak demand management and increasing the reliability of the electricity network, prioritizing the use of storage is necessary. The purpose of this study was to conduct a multi-criteria decision making (MCDM) approach to prioritize selected sub-distributive substations of Tehran for peak shaving, curve leveling, and economic criteria using battery storage. Also, the Shannon entropy weighting method and SAW implementation method were implemented. After prioritizing the posts and identifying the priority posts, we determine the appropriate size of the storage and determine the delay time, and the amount of benefit from delaying the development of the post when using the electrical energy storage. In this study, we used real data obtained from Tehran Regional Electricity and the data used for the 63 to 20 kW substations “EKBATAN”, “AZADI”, “AZARBAIJAN”, “ABOUZAR”, “SINA”, “DEPO”, and “YAKHCHI-ABAD”. The results show that the maximum installed storage capacity calculated for the priority post (i.e. DEPO) is 119.66 MWh and the maximum storage capacity is 18 MW. The most suitable storage size for installing is 120 MWh. Using the storage at the selected post will delay the development of the post for 7 years and the economic benefit is 40% of the investment cost.

The main purpose of this study is to identify and prioritize different gasoline pricing policies in Iran based on sustainable development indicators using the Delphi method and Analytical Hierarchy Process (AHP). To this end, first, various types of gasoline pricing options along with evaluation indicators of these options were extracted separately in economic, social, and environmental terms by the Delphi method based on reviewing studies and interviews with specialists and experts. In this section, four pricing options for gasoline pricing were extracted entitled (i) “Double pricing of gasoline or continuation of the current trend; (ii) “Single rate gasoline price and cash payment of subsidies to cars; (iii) “Proportional pricing for gasoline consumption; (iv) “Single price of gasoline and allocation of quotas to people instead of cars. Then, these options were evaluated and prioritized in terms of economic, social, and environmental indicators in the framework of the AHP method. The results show that pricing commensurate with gasoline consumption or consumption tax (third option) is the best pricing option among the mentioned options. In this option, environmental and economic indicators are of great importance, and the price of gasoline between the quota price and FOB is determined in proportion to the consumption of individuals and sudden price changes do not occur for all consumers and the price of gasoline is completely dependent on the consumption behavior of individuals. Thus high consumption is always faced with higher taxes and allows for a fairer distribution of subsidies and reduced smuggling incentives for this fuel.
