Renewable energies are more compatible with the environment and their preparation and production have less pollution. In addition, since there is no end in sight for this type of energy, renewable energies take on a greater share in the world's energy supply system day by day, even in countries with fossil energy. The purpose of this research is to investigate the factors affecting the consumption of renewable energy in OPEC member countries using the panel data approach in the period from 2004 to 2018. In this research, the effects of factors such as good governance index, human capital, intensity of carbon dioxide emission, income (GDP) and crude oil price were investigated. The results of estimating the model using the feasible generalized least squares (FGLS method indicated that the good governance index, human capital, carbon dioxide emission intensity and income (GDP) have a positive and significant effect on the consumption of renewable energy in OPEC member countries, but the price Crude oil has no significant effect on the consumption of this group of energies in the mentioned countries. Factors such as the high cost of establishing renewable industries in OPEC member countries and the dependence of these countries' economies on oil revenues can be considered among the reasons for this result.

Lack of security, political affiliations, formation, and upsurge of environmental problems are the most significant reasons for altering the approach of energy supply sources from fossil fuels to renewable energy sources. This alteration in approach necessitates a growth in the level of financial support and a rise in the technology level in extracting renewable energies. The purpose of this study is to investigate the effect of diverse methods of financing renewable energy projects, such as foreign direct investment, research and development expenses, and financial market development on the amount of renewable energy consumption for 26 developing countries from 2008 to 2019. The results of the Feasible Generalized Least Squares (FGLS) technique show that foreign direct investment and research and development expenditures have a positive and significant effect on the consumption of renewable energy, while the development of financial markets does not have a significant effect on the consumption of renewable energy. Based on the results, since the defined methods of financing do not have an adverse effect on renewable energy consumption, it is recommended that the government, to guarantee the indicators of the nation's welfare, including environmental quality, put the laws covering these financing methods in the main plan and support.

The purpose of this paper is to investigate the effect of investment in the renewable energy on Iran's macroeconomic variables. In this regard, statistical information related to the period 1991-2022 was used. For this purpose, the stochastic dynamic general equilibrium method was used. The information used in this article was collected from the Central Bank of Iran and the Ministry of Energy. The theoretical framework of the present study will be based on investment models, optimization and inter-sectoral balance. In this study, the effects of investment in the field of renewable energy through public and private companies are included in the model. The results obtained from the investment shock in the field of renewable energy indicated that investment in this sector had the greatest impact on the growth of economic added value in the industry, services, agriculture and oil and gas sectors. Also, the obtained results indicate that in order to increase social welfare and achieve economic development, a 4-year investment period with a 50% growth in the field of renewable energy infrastructure in the country is necessary.

In this research, the effect of oil price shock on the return of the Iranian stock market has been evaluated using a new quantile-on-quantile approach. To do this, first, the oil price shock has been calculated using the structural vector Autoregression method, then the effect of the oil price shock on the return of the Iranian stock market has been investigated using the quantile-on-quantile approach. The statistical population consists of the data related to oil variables and the stock price index of the Iranian stock market. The statistical sample includes 200 observations of the monthly data related to the oil variables and the stock price index of the Iranian stock market during the period of 1385: 1 -1401: 12. The results of this research show that the effect of the oil price shock on the Iranian stock market varies across different quantiles of the Iranian stock market returns. A negative oil price shock has a larger effect on stock market returns when the stock market is bullish. Also, in the normal state of the stock market; Positive oil price shock have a large negative effect on stock market returns. Based on these observations, it is concluded that the relationship between oil price and stock market returns can depend on the nature of oil price shocks and the performance of the stock market.

Environmental concerns and global warming have posed a challenge to the continued use of fossil fuels, especially oil. In order to achieve the goal of limiting the temperature increase to below 1.5 degrees Celsius compared to the pre-industrial era, the IPCC has developed scenarios considering the reduction of fossil fuel consumption and the increase in the use of renewable energy. This issue poses a serious threat to economies heavily reliant on oil exports, such as OPEC. To examine the effects of these scenarios, supply and demand functions for oil were estimated using the VECM model. The findings indicate that the oil supply function has a direct relationship with the real oil price, with a long-term coefficient of 0.1391. Additionally, one percent increase in the production of non-OPEC countries will lead to a 0.7323 percent increase in OPEC oil supply. The price elasticity of demand in the long term is estimated to be -0.077. The elasticity of industrial production in advanced and emerging countries is estimated 0.7756 and 0.6241, respectively. Based on the estimated coefficients, the changes in OPEC supply in the most pessimistic IPCC scenario will be 40% reduction in 2030 and 94% reduction in 2050 compared to 2010.

The current study has studied the threshold effects of energy consumption structure and GDP per capita variables on carbon emissions from 2002 to 2019 for 37 selected countries (with middle to high-income levels) using the non-linear approach of Panel Smooth Transition Regression Models. For this purpose, two separate models have been estimated by considering energy consumption structure transfer and GDP per capita variables. The results indicate a non-linear relationship between the studied variables in both models. The estimation results of both models show that GDP per capita (in the threshold state of energy consumption structure) and energy consumption structure (in the threshold state of GDP per capita) positively affect carbon emissions. Also, urbanization and trade openness have a positive effect on carbon emissions in both models. Thus, the results show that increasing efficiency in energy consumption and GDP per capita structure can significantly reduce carbon emissions. These findings point to the importance of optimizing energy policies and the crucial role of changes in the economic structure in managing greenhouse gas emissions.

Forecasting electricity demand is one of the most important issues of the electrical energy system. Considering the structural changes in electricity demand and the stylized facts of electricity consumption in different sectors of demand, forecasting the amount of electricity demand will clarify the prospects of changes in the Iran's electric energy system in the medium and long term. By using new approaches, this prediction will have higher reliability. In this research, using the state-space approach and combining it with Markov regime switching, the main sources of uncertainties were included in the model. By using the data of electric energy feed-in the system to supply electricity demand and the average real price of electricity and temperature and the number of customers in the ten-year period of 2013-2022, the parameters of the model were estimated based on the state-space approach and Markov regime switching. State-space approach in the form of time-varying parameters and Markov switching approach in the form of variance fluctuations were included in the model. The results showed that the model based on this integrated approach gives a more accurate prediction than the classical model of electricity demand. The standard error of the estimated equations is reduced to 0.1 (in the competing model, the standard error of the corresponding equation is 0.03, and in the integrated approach, it is 0.002 for peak and 0.004 off-peak periods). The sensitivity of electricity demand to the real price of electricity and temperature changes is decreasing and the demand for marginal costumer is increasing.

The need for development is increasing and the demand for energy is rising. The construction of new power plants has become necessary to meet this growing demand. To protect the environment and conserve finite fossil fuels, renewable energy sources are crucial to the transition to green energy production. Examining the impact of energy production on the environment is crucial, and not just in terms of financial, economic and geographical factors. The aim of this study is to understand the contribution of renewable and non-renewable power plants to the total emissions generated over a one-year operating period. The RETscreen analysis software was used to estimate the emission coefficient and a cost-benefit analysis method was used to evaluate the environmental impact. The value of each ton of carbon dioxide and the discount rate for environmental effects are key factors in estimating the emission coefficient of the different energy systems. Renewable energy systems have an emission coefficient of zero, while gas turbine systems, two-way gas engines, two-way biogas engines and coal-fired steam turbines have emission coefficients of 700, 747, 45 and 1,509 billion rials, respectively.

Energy is a fundamental input in production, and its availability and use are essential for the social, economic, and technological advancement of a nation. Energy consumption and greenhouse gas emissions have been increasing along with rising production, primarily sourced from non-renewable resources. The increase in production and economic development has led to higher greenhouse gas emissions, resulting in climate change, which poses a new challenge for countries. Energy efficiency is the most beneficial way to reduce greenhouse gases and control energy supply. In this regard, one of the responsibilities of governments is to find tools to minimize the national economy's energy efficiency gap by increasing energy efficiency within the economy.For this purpose, in this study, we used the Shephard energy distance function to define the energy efficiency index and the stochastic frontier analysis technique to estimate the energy efficiency gap in selected oil and gas producing countries from 1990 to 2022. We examined some factors influencing the energy efficiency gap and observed that the energy efficiency gap increased from 6% to 29% during the years under review. Additionally, foreign direct investment and total factor productivity have a negative impact, while urbanization has a positive impact on the energy efficiency gap.

One of the goals of the green economy is to reduce the negative environmental effects caused by the use of natural resources in developing economies. Investigating the separation of economic growth from fossil fuels is a key task that has been addressed in few studies. Therefore, the main purpose of this research is to investigate the effect of economic freedom on the process of separating economic growth from fossil fuels. In this study, the method of estimating the model is based on panel data, which is in the period (2000-2020) and for "developing countries (Iran, Brazil, India and China) and developed countries (America, England, Germany and France)" has been done. The estimated models are presented in the form of multivariate linear regression models according to the research hypotheses. Based on the obtained results, the first hypothesis according to the results of the fixed effects model and the generalized least squares method, the economic freedom variable had a positive and significant relationship with the dependent variable (economic growth rate). Therefore, for both groups of Countries at the 95% confidence level, economic freedom had a positive and significant effect on the process of separating economic growth from fossil fuels.

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.

The purpose of this study is to investigate the price elasticity of household and non-household electricity demand across 31 provinces of Iran from 2011 to 2021. Due to the skewness of the dependent variable, the panel quantile regression method was chosen. The results show that the price elasticity of household electricity demand ranges of -0.069 to -0.115. The price elasticity demand of non-household ranges from -0.021 to -0.043. It reveals that price elasticities are less than one for both groups. According to the results, electricity is an inelastic good in Iran. Also, the elasticity of electricity demand is higher for households than for non-household. Moreover, the results show that an increas in the price of natural gas, which is the closest substitute for electricity, has had a negligible impact on the electricity demand of the household and non-household sectors. Among other model results, we can mention the incredible influence of demand habits on household and non-household electricity demand.

Pricing gasoline and optimal allocation of resources have always been topics of interest for governments and experts. The increasing jump in the exchange rate has created a significant difference between the nominal and real prices of gasoline. Therefore, in the present study, a solution is proposed to narrow the existing gap by introducing a floating tax proportional to gasoline consumption, and its effect on household income distribution is examined. On the other hand, the regressive feature is a weakness of the consumption tax system that leads to undesirable effects on income distribution by imposing a higher tax burden on vulnerable classes. Therefore, the proposed scenario in this study is similar to the current pricing system and is in the form of two-tiered rates (quota-based and non-quota-based rates). The quota-based section is exempt from taxes and is similar to the past procedure, while the non-quota-based gasoline price is calculated based on individuals' consumption, considering a 5% tax for each liter of consumption exceeding the monthly quota. If the consumption increases, instead of receiving more subsidies, the higher expenses will accompany the consumer. In this regard, by using an almost ideal demand system model, the effects of implementing the proposed scenario on inequality and income distribution among urban households were studied, and categorized into four gasoline consumption groups (less than 60 liters, 60 to 80 liters, 80 to 120 liters, and more than 120 liters) during the years 2017-2020, considering some demographic variables such as household size, gender, age, marital status, employment, education, and household head's ownership of housing. Price and income elasticities were extracted, and the compensatory variation (CV) index of changes was calculated. Assuming the implementation of the proposed scenario and the constancy of prices for all commodity groups except gasoline, the household expenditure data was simulated, and inequality was calculated using the Gini coefficient. The results show that if the above-mentioned scenario is implemented by the government, assuming the constancy of prices for other commodity groups, a relative improvement in the Gini coefficient is obtained, indicating a reduction in inequality.

Energy subsidies encompass explicit subsidies and implicit subsidies (opportunity costs), both of which significantly influence economic agents' decision-making, as described in the theoretical literature. Iran faces several pressing issues, including escalating energy consumption, inadequate price signaling to address consumption patterns, increasing greenhouse gas emissions, and prevailing distributional challenges related to energy subsidies. Consequently, reforming energy carrier subsidies in Iran becomes an imperative task. However, numerous obstacles hinder the effective implementation of this policy, presenting substantial challenges. This study employs a comparative approach that incorporates expert opinions and utilizes the Fuzzy Analytical Hierarchy Process (FAHP) method with a holistic perspective to evaluate and rank the barriers to energy subsidy reform. The identified barriers are categorized into three groups based on specific criteria: 1) political and social barriers, 2) economic barriers, and 3) institutional and governance barriers. Subsequently, thirteen sub-criteria have been established, considering Iran's economic conditions. The research findings highlight the significance of economic barriers, accounting for 53% weight, followed by political and social barriers with 26%, and institutional and governance barriers with 21%. Notably, among the economic barriers, the high dependency of energy industries on the country's exports and the government's concerns about potential damage to foreign exchange revenues, particularly under sanctions, emerge as crucial factors. Regarding political and social barriers, the prevalent mindset of entitlement among citizens regarding energy subsidies proves noteworthy. Additionally, the lack of a cohesive and reliable database for implementing energy subsidy reform policies assumes utmost importance among institutional and governance barriers. Based on these results, it is imperative for the government to undertake measures encompassing formulation, implementation, and evaluation in all dimensions of energy subsidy reform

The current study deals with the effect of GDP, urban population and non-renewable energy consumption on carbon dioxide emissions in OPEC member countries. To show the details of his findings, in this study, using the panel data method, the effect of GDP, increase in urban population and non-renewable energy consumption on carbon dioxide emissions for 13 OPEC member countries in the period of time, 1990 to 2019, was reviewed. The results show that GDP, urban population increase, and consumption of non-renewable fuels have a positive and significant effect on carbon dioxide emissions. The general findings indicate that following the increase in gross domestic production and the industrialization of countries, we will also witness the growth of the urban population. Environmental pollution is mainly aggravated by rapid urbanization and industrialization, as well as economic growth and non-renewable energies in OPEC member countries, which are mainly developing countries, and have destructive effects on the environment. This study recommends that sustainable urbanization and economic growth should be promoted using green finance and clean energy sources. Also, the need to change energy consumption patterns from fossil fuels and move towards renewable energy sources should be supported among OPEC member countries

The equality implications of tariff design for household gas and electricity, two essential substitutes, present a significant concern for policymakers. In this study, we examine this issue using a sample of household income quartiles across various social groups, exploring the diverse effects of changes in electricity and gas prices. The findings reveal that an increase in gas prices exerts a more pronounced impact on low-income groups compared to an equivalent increase in electricity prices. Our partial analysis indicates that gas exhibits less elasticity, likely attributed to the absence of a suitable substitute in the event of a price increase for this commodity. This observation underscores the lack of energy diversity that is rooted in the critical role of gas appliances in cooking and heating. This phenomenon poses a potential threat to the energy security of Iranian households.

The main purpose of this study is to investigate the effect of economic and social factors on the emission of carbon dioxide, which has been used as a measure of environmental pollution in Iran for the period of 1352-1397. In order to measure the economic and social factors affecting environmental pollution, it is necessary to study the short-term and long-term relationship between fuel oil consumption, urbanization, economic growth, and carbon dioxide emissions in Iran. For this purpose, the autoregression model with extended distribution intervals (ARDL) was used. The results show that the error correction coefficient obtained in this model shows that in each period, 33% of the short-term failure error can be made to achieve a long-term comparison. According to the estimate, the increase in fuel oil consumption, urbanization, and economic growth have a positive effect on carbon dioxide emissions both in the short term and in the long term. Also, the long-term results indicate that with an increase of one percent of gross domestic production, fuel oil consumption and urban population increase carbon dioxide emissions by 0.849, 0.166, and 1.566 percent, respectively. Therefore, the first step to reduce carbon dioxide emissions in the country is to pay attention to the amount of fuel oil consumption, hence policies can be made to use alternative energies such as renewable energies to reduce carbon dioxide emissions.

The main goal of this research is to design a composite economic-energy-environmental performance index (3EPI) for Iran's economy by generalizing the methodology of Khramov and Lee (2013) as well as evaluating the effect of variables on the composite performance index during the period from 1991 to 2021 using a time-varying parameters model (TVP). The 3EPI index is calculated in a weighted and unweighted form, and the trend is separated from the cyclic with the Hodrick-Prescott filter. The findings show that the long-term trend of the 3EPI index is in the range between 35 and 60 percent, which is significantly different from the base number of the index (i.e. 100 percent). The chronicle of the index shows that the worst performance is related to the implementation period of the structural adjustment policy (1994 and 1995), the first round of economic sanctions (2012), and the intensification of economic sanctions in the latest round of sanctions (2019). The best performance is related to the two periods of the relative stability of macroeconomic variables and the period of implementation of the JCPOA agreement. The results of the application of the TVP model show that, from 2011 to 2021, the variable of the budget deficit to GDP ratio had the most significant negative impact on Iran’s 3EPI performance index

Oil and natural gas production is not uniformly and homogeneously distributed across all provinces of Iran, whereas a major part of oil and gas incomes is consumed in provinces that do not have any significant role in oil and gas production. Therefore, any disruption in the production of oil and gas might expose the GDP growth of all provinces at risk. In this paper, the multiregional input-output table is calculated for the year 2015. Then, the hypothetical extraction method introduced by Dietzenbacher and Lahr (2013) is employed for estimating the effect of partial and complete extraction of oil and gas production in Khuzestan and other oil-oriented regions on the value-added of 71 economic activities in each of the regions. The findings reveal that firstly, following the extraction of oil and gas production in Khuzestan, the value added of this region reduces about %32 , while the extraction of the corresponding sector in other oil-related regions will mitigate this region’s value added by %14. Secondly, the relative reduction in the value added of economic sectors and each sector’s contribution of value-added reduction in each region depend on the economic structure of the interested region. The highest share of the total value-added reduction in each region belongs to the service sector in Tehran and agriculture in other non-oil regions. It seems that diversifying energy resources as well as supplying regions, enhancing fuel consumption efficiency, and renovating the transportation system are the most important policies to have more resilience.

Corruption and political risk are important factors affecting the economies that can affect various aspects of people's lives. On the other hand, one of the important economic indicators that shows the intensity of energy consumption, and in other words, the amount of energy consumption in each country, is the energy intensity. Energy intensity is a crucial indicator by which we can understand the trend of changing energy efficiency in different years. Given the importance of this issue, the present study examines the effect of corruption and political risk along with other factors on the energy intensity of selected countries in the Mena region, including Iran, Bahrain, Egypt, Iraq, Jordan, Kuwait, Lebanon, Qatar, Saudi Arabia, and UAE using by a panel data model for 2003 to 2019. The results show that corruption, political risk, and factors such as good governance, foreign investment, and human development are important. Therefore, improving education and awareness by reducing corruption and political risk can lead to better implementation of energy efficiency programs.

In recent years, the share of renewables in the global energy basket has increased significantly. This will have geopolitical consequences, especially for a country like Iran, whose economy is largely dependent on fossil fuel revenues. By examining the transition process of the global and regional economy towards renewable and clean energy, this article tries to outline Iran's position in the energy transition perspective. The main question is: how will Iran position itself in the global energy transition outlook to 2050? Through scenario planning, the authors identified four possible scenarios, including "meeting sustainable development and transition to green gold", "gradual and independent transition to sustainable development and green gold", "development based on black gold" and "development locked with black gold". They cover a wide range of possible futures. By knowing these scenarios and comparing their desirability, policymakers will be able to properly assess the costs and opportunities of the transition to clean energy in different situations.s

This paper focuses on the analysis of the petrochemical products manufacturing value chain and the presentation of petrochemical products' optimal manufacturing pattern in petrochemical industries affiliates of pension funds. The case study in this research is JAM and MASJIDSOLEYMAN Petrochemical companies. Period of this research is 5 years. In this case study, the determiner faces paradoxical objectives simultaneously. The fuzzy multi-objective linear programming (FMOLP) method has been used based on the α-cut of fuzzy parameters in this research. The goal of this research is to extract the amount of products that have maximized profit and value-added and minimized risk simultaneously which face technological, market, financial, budget, legal, and national interest-related limitations. This method is often interested in the proper POSs that have finite tradeoffs between objective functions. One numerical sample has been used to show the possibility of using the said method in multi-objective optimizing issues for the production of propylene. Because of the efficiency and satisfaction of the obtained new solutions for this method, this method undoubtedly can be useful to solve the FMOLP problems. A decrease in the production of ethylene and light polyethylene and an increase in propylene and butadiene production is the most important policy recommendation of this research.

Managing energy consumption in smart buildings has become an increasingly important challenge. Efficient energy management can have a positive impact on both micro and macroeconomics. Moreover, it is essential to ensure that the comfort of smart building residents is maintained at an acceptable level. Optimization algorithms can be used to achieve user convenience while minimizing energy consumption. In this study, we propose an optimization approach that utilizes an agent-based architecture. This architecture comprises intelligent agents that communicate with each other via message exchange in a network structure consisting of three layers: (1) The switch layer monitors user preferences and comfort levels. (2) The coordination layer includes a coordinating agent that determines the optimal timing for electrical appliances to minimize electricity consumption costs and maximize user comfort. (3) The execution layer contains performer agents. Our focus in this research is on the coordination layer with the aim of reducing energy consumption costs and peak average rates, while increasing user comfort to the highest possible level. However, this optimization problem is highly complex due to the large number of electrical devices and their capabilities. To address this, we propose a hybrid method based on genetic and bat algorithms. We evaluated its performance based on objective functions and compared it with recent research on SmartHome and CU-Bems datasets. Our results demonstrate an improvement in performance

The purpose of this study is to compare the economic efficiency of Iran's petroleum contracts, buyback contracts, and production-sharing contracts. This study also determined the optimum path for production and drilling operations in the Yadavaran oil field which has special importance because it is a joint field with Iraq. It was estimated using real field data and the SQP algorithm by MATLAB software. First, the objective function, the constraints of each contract model, and the cost function are defined and expressed based on field data. For the objective function, the oil price is determined based on the reference price scenario and based on the forecast of the US Energy Information Administration (EIA). Cao et al (2009) 's cost function model is also modified by using historical field data (first development phase data) to be applied to the study field. The results show that the most efficient oil contract is the Iran petroleum contract, with a low floor for capital costs and no limit to the number of drilled wells. it was proved that the buyback contract with the ceiling of capital costs incompatible with the recovery coefficient has recorded the lowest efficiency. Also, the Iran petroleum contract can be a good alternative to the buyback contract, because it can well solve the problems of the buyback contract, especially for joint oil fields where the priority of the objective function of the maximum cumulative production over the objective function of the maximum present value of the total profit is more desirable.
