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.

Half a century after the oil crisis in the 1970s, there is still not any agreement among economists when it comes to the type and existence of any relationship between energy consumption and economic growth. In this regard, many studies have been conducted, and many methods have also been adopted to find this relationship, most of which are now proved to be inappropriate and inefficient. Having utilized a new causality approach proposed by Konya (2006), this study investigated the relationship between three energy carriers, natural gas, electricity, oil products, as well as considering the value-added of sixteen main industrial sub-sectors in the period 1995-2017, via the bootstrap panel approach. Comparison to the traditional methods, one of Konya's merits is paying attention to the two categories of heterogeneity of coefficients and cross-sectional correlation, making the estimation of parameters more efficient. The results show that in five sub-sectors of the industry, including “rubber and plastic”, “other non-metallic mineral products”, “manufacture of machines and unclassified equipment”, “machinery generator, electric transmission, and unclassified electrical appliances”, “manufacture of motor vehicles, trailers and semi-trailers” there is a one-way causal relationship from value-added to natural gas consumption. On the other hand, in an industrial sub-sector of “manufacture of chemical products”, this relationship is two-way. Also, there is a lack of causal relationship between electricity consumption and value-added in sixteen industrial sub-sectors. Moreover, a one-way relationship from value-added to the consumption of oil products can be seen only in the industrial sub-sector of “manufacture of other transport equipment”. According to the results of this study, it seems that energy consumption is not dominant in the economic growth of the Iranian economy, and the government can adopt necessary policies regarding energy price liberalization and demand management without worrying about its dire consequences.

The formulation of effective energy efficiency (reducing the energy intensity) policies requires study of the factors affecting energy intensity. The final consumption of energy in the manufacturing sector of Iran has grown significantly in recent years. The purpose of this study was to investigate the factors affecting the energy intensity in the manufacturing industries of Iran, especially the effect of government expenditures and foreign direct investment on the energy intensity in these industries and controlling the spillover effects between provinces using provincial panel data of Iran from 2000 to 2014. Based on Panel (Robust) LM, Wald and LR tests, Spatial Durbin Model (SDM) has been used to investigate the spillover impact effects of energy intensity. According to the results, energy prices, private ownership and government capital expenditures have a negative effect on energy intensity, while export-value added and capital-labor ratios have a positive impact on energy intensity. Foreign direct investment also did not have a significant effect on energy intensity. These results call for greater attention to the adoption of higher production technologies in investment and the role of the government in energy intensity changes. The results indicate possibility of using neighboring enrichment policies to increase energy efficiency.

It is clear that any planning and policy making about economic growth as one of the macroeconomic purpose’s, need to special consideration to the environment and its relationship with production. therefore, in this study, we employ a maximum entropy Bootstrap to assessment the causality between carbon emissions and economic growth more accurate in comparison to conventional hypothesis tests based on asymptotic theory. We employ simulation based inference to investigate the causal relationship between carbon emissions and economic growth in Iran for the 1973–2010 period, both in a bivariate and a multivariate framework by including energy consumption per capita, financial development and openness variables in the model. In bivariate model, Our results indicate that there is uni-directional causality from GDP per capita to carbon emissions per capita while multivariate framework shows no evidence of a causal relation between carbon emissions and growth. Results indicate that there is uni-directional causality from GDP per capita to energy consumption per capita. So we can employ environmental policies without any reduction of economic growth.

Since energy resources are of prime importance and limitation in Iran's economic developments, specifying the quality and quantity of the effective factors in energy requirments are of particular significance. In this research, first the effective factors on energy request as well as the effect of financial development along with GDP are surveyed. Then the population are surveyed in energy consumption along with ARDL technique using with Granger causality in the period of ( 1363-1390). Meanwhile, the long-run relationship among variables were verified using the test group of Pesaran. For more detailed evaluation of the obtained results of this study, the method of "bootstrap" is used to compute the standard deviation, confidence interval, correct bias and the statistical inference. The results show that financial development has a positive and meaningful effect on the electricity consumption. Also it show that there is bi-directional causality between financial development and economic growth. and causality is from financial development to electricity consumption. Electricity consumption is affected by both economic and financial development. According to the results of the study, to achieve economic development, the demand for energy, in addition to financial development should carefully examined.

Industrialization leads to emission of carbon dioxide from extensive use of fossil fuels. This study investigates the dynamic relationship between economic growth, trade freedom, coal consumption and carbon dioxide emission in Iran. An autoregressive distributed lag (ARDL) model is designed to study the short term and long term relationship. After evaluating the model for unit root test, a logistic regression analysis was run on the basic of 1986-2012 data for the economy of Iran. Our findings indicate the existence of a significant correlation between economic growth, trade freedom and coal consumption with carbon dioxide emission. Thus the presence of Environmental Kuznets Curve are confirmed both in the short-run and long-run. Panning for coal consumption reduction can be emphasized as a policy tool for emission reduction.

A large portion of the world energy consumption is provided by fossil fuels, which cause massive emissions of dangerous pollutants into the environment leading to global warming and climate change. What is certain is the world's energy consumption in order to increase economic growth and the resulting greenhouse gas emissions, especially carbon dioxide, the consumption of fossil fuels is a growing trend. Therefore in the present study to examine the causal relationship between CO2 emissions (as an alternative to the destruction of the environment variable) and variables of FDI, per capita energy consumption and GDP in the form of an environmental Kuznets hypothesis in Iran during 1980-2008. To that end, The Toda-Yamamoto method, has been used to examine the causality relationship. The main finding of this study shows that there exists bidirectional causality between CO2 emissions and energy consumption and unidirectional causality running from GDP to CO2 emissions. Given the existence of causal relationships between variables, the hypothesis of environmental Kuznets curve (EKC) in state variables that criterion economic growth CO2 emissions and energy consumption is to be confirmed, but in that case the criterion of economic growth, GDP is confirmed is not.
