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.

The purpose of this research is to investigate different levels of country risk and its role in the relationship between renewable energy consumption and economic growth in Iran, during the period (1997-2021). In terms of purpose, this research is of applied type and in terms of causal-analytical method, and the method of collecting information is of documentary-library type. After calculating the threshold value of each variable, we analyzed the effect of renewable energy consumption on economic growth using the threshold distance of different country risks. The results indicate the non-linear effect of renewable energy consumption on economic growth under different risks in the country. This research is one of the first studies in Iran that analyzed the relationship between renewable energy consumption and economic growth based on a risk-based approach. According to the regression model described in the current research, this research provides suggestions for developing a suitable strategic plan with the aim of specifying short-term and long-term goals, and future vision, as a road map for those involved.

The increasing population and rising demand for water and energy supply, along with the exacerbation of environmental pollution effects on natural and human resources, demonstrate the vital need for a cohesive movement toward the water, energy, and environment Nexus (WEEN). Since the electricity generation industry has a significant share in water and fuel consumption and CO2 emissions in Iran, in this study, the application of a combined renewable system in the Zarand Steam Power Plant was evaluated based on the Nexus approach. Solar system designing and carbon balance evaluation during plant lifetime was conducted via PVSyst software in 2021. Also, an environmental model of ReCipe was applied to evaluate the effect of carbon reduction on the ecosystem. The results have shown that replacement of at least 1% of the nominal capacity of the fossil power plant with renewable sources, will significantly prevent 1249/46 t CO2 emission annually in this power plant which is equivalent to 362/160 m3 fossil resources storage and 373/73 TOE.year-1 energy savings. Also, the results showed that in addition to protecting valuable natural resources, the combined cycle will lead to a significant reduction in water demand equivalent to 3660 m3 having the capacity of supplying underground water resources. Considering the benefits of saving water and energy resources and reducing carbon emissions, from the NEXUS approach, in addition to managing energy supply through replacing resources and using water and heat recovery technologies, applying energy demand management policies based on energy efficiency and its environmental effects is suggested..

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 importance of economic relations and environmental potential issues, the relationship between economic growth and environmental degradation is a very important issue. Therefore, understanding the relationship between GDP growth, consumption and extraction of fossil fuels, use of renewable energy, and emissions in the Iranian economy are very important for sustainable development. In this study, we try to investigate how emissions (as the main cause of pollution) are affected by per capita income growth, innovation, renewable energy consumption, and extraction from non-renewable energy resources in a model with four equations (for Iran in period 1979 to 2019). By reviewing the wide range of studies, the framework developed in this paper has not been investigated in domestic or international studies. On the other hand, in this research, for estimating nonlinear simultaneous equations, the multi-objective optimization method and its application for estimating simultaneous equations in econometrics have been developed. (This method can be a way to estimate nonlinear simultaneous equations in future studies). The results showed innovation activities have not been able to have a significant effect on reducing pollution emissions for the Iranian economy. Also, we found out the consumption of renewable energy has not had a significant effect on reducing pollution emissions. Also, the existence of the Kuznets environmental hypothesis was confirmed and Iran is in the upward part of this curve.

Energy has always played a very important role in human life and is one of the factors that can make economic growth possible. Today, many countries are struggling to invest in new technologies by using renewable energy sources such as solar energy, wind energy, or water energy as their needed sources of energy, which, as compared to fossil fuels, generate lower environmental pollution. The purpose of this study was to evaluate the economic growth of the selected countries of the MENA region from renewable energy sources using the Panel Vector Autoregressive Model in the period of 1990-2015. The results of the study showed that the variable of the total energy produced from renewable sources has the largest share in explaining the changes in the economic growth of the countries under study and its explanatory value reaches 56% in the long run. Given the significant impact of renewable energy consumption on economic growth, suitable policies for renewable energy are needed to achieve a high level of production and social welfare. In this regard, granting financial incentives, establishing a fund for renewable energy by the government, and creating conditions for developing the renewable energy industry in the country could be solutions

The paper investigates the effects of oil price fluctuations on the installed capacity of wind energy in developing countries in comparison with the impact of economies of scale and technical learning. To this end, we used rolling regression analysis and data from 2003 to 2015 to calculate annual technical learning rates. Using the panel data regression and autoregressive model based on panel data we analyzed the effect of oil price fluctuations on wind energy installed capacity as the most advanced renewable energy in developing countries. The results show that oil price changes in the long run have a positive but limited impact on the development of renewable energy in developing countries. Oil price shocks, although in the short term and driven by the incentive of developing countries to transfer higher-tech technologies to renewable energy can not in the long term alone, guarantee the development of renewable energy in these countries

The main objectives of the present study were evaluation of the economic, welfare and environmental effects of applying Feed-in tariff policy in the Iranian Economy. In this regard, the E3 type of hybrid recursive dynamic model was studied. Therefore, the model is used for the period of 1390-1404, to evaluate the effects of FIT policy under two different scenarios, similar and different guaranteed purchase price, in order to achieve 10% share for renewable energy in total electricity production in 1404. The result shows that in in both cases, pollution and its social cost reduction has been mainly caused because of the reduction in the sectorial GDP. Therefore, a definitive statement about the selection of a proper policy depends on the environmental purposes of the country.

Nowadays, greenhouse gas emissions and consumption of fossil fuels has led to environmental problems such as global warming which result in using low carbon energy sources and renewable energy as a potential substitute for fossil fuels and nonrenewable energy. This study is going to investigate Environmental Kuznets curve (EKC) for 11 elected OPEC countries, from 1980 to 2013 by using nonlinear quadratic model. The consumption of renewable and nonrenewable energy are considered together in this model which has been carried out by PMG (Pooled Mean Group). According to the outcomes of the research the Environmental Kuznets curve hypothesis is confirmed in these selected countries and studied period. The coefficient of nonrenewable energy consumption is statistically significant at the 0.01 significance level. Its estimated coefficient is 0.67 and states a 1% increase in nonrenewable energy consumption which leads to CO2 emission rise by 0.67%. It indicates that overusing of nonrenewable energy and fossil fuels increases environmental and air pollution. Also, the coefficient of renewable energy consumption is -0.005 that it is not statistically significant.

Development of renewable energy would help to achieve the goals of economic, social and ecological development which are considered as the most important factors in achieving sustainable development in each country. This article examines the impact of real economic growth per capita on the country's clean energy deals during the period 1967-2012 in Iran. To this end, the pattern Auto Regressive Distributed Lag (ARDL) and Co-Integration method are employed to determine the presence of short and long-term relations among the variables. The results show that the speed of adjustment is relatively high error correction model and the model is able to adjust the 61% of short-term imbalance error, to achieve long-run equilibrium. According to the corresponding estimations, the relationship between real economic growth per capita and renewable energy consumption, combustible renewable and waste consumption and electrical energy consumption in both short-term and long-term is negative. Also Long-term results have showed a significant negative relationship between electrical energy consumption, renewable energy consumption combustible renewable and waste consumption and real economic growth per capita. So, in long- term, increasing one percent consumption of the mentioned variables, cause to decrease the real economic growth per capita to 0.71, 0.72 and 0.79 respectively.

Environmental tax and subsidy are two key instruments used in many countries to prevent environmental degradation and to achieve sustainable development. Using game theoretic approach, this paper develops and calibrates a model to determine optimum indirect environmental tax for Iran. More specifically, in the first stage the government sets green taxes and subsides, and in the second stage, the final goods and energy producing firms take these rates and choose their inputs. This dynamic game is solved by backward induction. Prior to our calibration, the production functions for fossil energy, renewable energy - as an intermediate goods - and final goods are estimated. The model is calibrated by using the Iranian data for the period 2015. The results indicate that the optimum green tax rate on fossil energy producing firm and final goods firm are 18 and 9 percent, respectively. These results have important policy implications for policymakers and social planners in Iran.

The main purpose of this paper is to determine the amount of subsidy required to promote the share of renewable energy in total electricity production. To do so, different scenarios have been studied by a hybrid approach of Computable General Equilibrium model. The results have been created by entering the details of technology-specific information for electricity generation into this model. The result of codification and calibration of the model shows that in the case of applying same subsidy to achieve 10 present shares of renewable energies in total electricity production, there is a need for 851 percent subsidy rate. Although in this case the wind energy is the only activated resource and the solar and biogas sections have not succeeded in achieving any rise in production rate. The other scenario was based on the unequal subsidy, proportional to disadvantage of different renewable energy. The result shows that, to achieve a balance growth of 4 percent energy productions from renewable sources, the rate of subsidy for wind energy should be 887 present. This rate for solar is 1776 present and for biogas is 1585 present. So, in the first scenario, the proper tariff for purchase of electricity from renewable energy is 4100 Rials per kWh. This tariff in the second scenario is 4260, 8520 and 7600 Rials per kWh respectively.

The impact of information & communication technology (ICT) on people's lives can be study in different aspects. From economic and environmental perspective, the outcomes of the efficiency and productivity activities, has an important role because the improvement of efficiency provides a basis for reducing energy consumption .This Paper examines the impact of information & communication technology (ICT) on petroleum products in transportation Sector of the selected OECD & OPEC countries for the period 2000-2010 , and for this purpose ,dynamic panel modes are used. The results show that ICT has different rules in the samples. In the selected OECD countries, more use of information and communication technology can increase the intensity of consumption of petroleum products of the transportation sector, while in the selected OPEC countries more use of ICT can reduce the intensity of consumption of petroleum products of the transportation sector and ICT has the potential for reduction of energy intensity in the transportation sector of these countries that have high energy intensity.

With regard to the ever-increasing need for energy in current societies to satisfy various requirements, scientists and researchers from different countries, such as Iran, have a basic approach in their agenda to achieve renewable energies. The scientists believe that with regard to the limited fossil fuels and their environmental pollutions, renewable and clean energies can be the first alternative to generate energy. Our country, Iran, has numerous capabilities in the field of generating new and renewable energies. This fact emphasizes the need for an optimum model to develop the use of renewable energies. In line with this objective the costfunction is chosenas the objective function. Given the potential and limits ofrenewable energy (resources Limited), Consumptionof electricpowerin each of16regions (apply Limited) confidencelimits of renewable energy (technical limitations), the model was designed and with use Robust optimization model was solved in LINGO software.The optimum of using renewable energies suggests the 36.71% generation of small hydropower energy, 18.22% wind energy, 17.19% biomass energy, 13.43% geothermal energy, 12.53% tidal energy, and 1% solar energy.
