The unprecedented increase in energy demand due to population growth and developmental needs has intensified the necessity for constructing new power plants to meet this demand. This study aims to examine the environmental impacts of renewable and non-renewable power plants from the perspective of greenhouse gas emissions. The RETScreen software has been employed to calculate emission factors, and a cost-benefit analysis approach has been used to evaluate environmental impacts. Estimates reveal that renewable power plants such as wind and solar plants have zero emissions, whereas non-renewable power plants emit significant amounts of carbon dioxide.This study calculates the emission factors of power plants per megawatt-hour of electricity generation. According to the data, coal-fired power plants have the highest emission factor, equivalent to 1.0734 tons of carbon dioxide per megawatt-hour, whereas this factor is zero for renewable energy-based power plants. Furthermore, an analysis of environmental costs indicates that non-renewable power plants incur substantial costs. For instance, the annual environmental cost of operating a coal-fired power plant is estimated at 1,509 billion IRR.This research provides guidance to energy policymakers, emphasizing that selecting renewable technologies not only helps reduce greenhouse gas emissions but also eliminates environmental costs. Adopting supportive policies for the utilization of clean energy can pave the way for a sustainable future in energy production while minimizing the adverse environmental impacts of non-renewable power plants.

The country's oil industry, as the most important source of foreign exchange earnings and the largest energy sector in the country, has high potential for realizing resistance economy policies. Selling crude oil through the stock exchange can be considered one of the ways to reduce the effects of sanctions. This method of selling crude oil has many advantages. However, the supply of crude oil on the energy stock exchange has been unsuccessful in practice. The present study has a qualitative approach and, using the content analysis method, has attempted to identify the causes of the failure of the supply of crude oil on the energy stock exchange and also to provide solutions for the successful supply of crude oil on the energy stock exchange. Then, the identified solutions have been prioritized using the Friedman nonparametric test.Among the most important solutions presented in this research are: creating a variety of trading instruments, active energy diplomacy, structural reforms in the energy exchange, establishing an oil consortium, collaborating with the Shanghai Stock Exchange, and creating a barter settlement room. This study shows that if the obstacles to the supply of crude oil in the energy exchange are removed and attention is paid to the proposed solutions, there is hope for the successful supply of crude oil in the energy exchange.

Energy is a input in the production sector and used in the distribution and consumption of many goods and services, which should be used optimally. One of the indicators showing the optimal use of energy input is the EII. Obviously, the lower the EI, it means that less energy has been used for each unit of production of goods and services. Several factors can be mentioned that affect EI, of which innovation is one of the key ones. Purpose of this article is to investigate the influence of several factors on EI in selected countries of the MENA region during the period of 2010-2020. The panel data model for 13 selected MENA countries have been used. The results show that the influence of control variables including "government consumption expenditure", "energy price" and "trade openness" on EI is negative and significant. The findings of the first model indicate a negative and significant effect of the OII on EI, and the estimation results of the second and third models also indicate a negative and significant effect of the innovation sub-indices (ICT and financial access) on the energy intensity of the selected countries in the period. is under investigation. Considering the findings of the research, it is recommended that the economic policy makers pay special attention to the category of innovation and place their investments and policies with more focus in this area, because according to the findings of the research, innovation is an effective factor in reducing energy intensity

Several studies indicate that economic conditions impact energy intensity. Business cycles, a core element of macroeconomics, are crucial in this regard. This study focuses on exploring the asymmetric influence of business cycles on energy intensity in Iran from 1972 to 2020. To examine the relationships between variables, Nonlinear Autoregressive Distributed Lag (NARDL) analysis was employed. The model reveals that in the short term, a negative business cycle impact initially decreases energy intensity until a certain point, after which it increases till a specific threshold before showing a long-term positive trend. Conversely, both short and long-term positive business cycle impacts have a negative effect on energy intensity. Moreover, the study demonstrates that short and long-term coefficients associated with the logarithmic OPEC oil price variable are positive, while the industrial structure index logarithm shows a 0.12% decrease and a 0.04% increase in short and long-term energy intensity, respectively. The Wald's test outcomes indicate an asymmetric impact of positive and negative business cycle impulses on energy intensity in the long run, whereas the short-term effect appears to be symmetrical. Understanding business cycles can aid policymakers in making informed decisions regarding energy industry development, effectively curbing excessive energy intensity growth

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, carbon dioxide emission intensity, 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 Crude oil price Does not have a 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.

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 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
