This study examines the correlation and causal relationship between energy carriers' consumption and Iran’s provinces' gross product for the period 1988-2017 using wavelet analysis with panel data and the Dumitrescu-Hurlin causality test. The results of correlation analysis show that the correlation pattern between energy consumption and GDP, in different energy carriers, is different. The correlation between natural gas, gasoline, kerosene, and electricity with GDP is strong at all energy intensity levels. The correlation between furnace oil and GDP is reported to be low and weak for all provinces in the long run. Furthermore, the findings show that in provinces with high energy consumption intensity, consumption of gasoline, fuel oil and total energy have led to GDP in the short run. In high-intensity cases, consumption of kerosene, gas oil, fuel oil and natural gas, in medium intensity all types of energy, and in low intensity, consumption of kerosene, furnace oil and gasoline have led to GDP. In provinces with very low energy consumption, energy carriers' consumption has not led to GDP while in the medium and long term, the feedback hypothesis is proven

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.

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.
