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.

Among energy carriers, the role of oil is more remarkable in economic development of developed and developing countries. But the fluctuations in oil price, existence of constant challenges between suppliers and demanders, the beginning of descending trend of production and promoting the energy security in its consuming countries have caused besides oil, its substitutes find specific importance. Development and extraction of unconventional resources on one hand have made changes in reservoirs ranking in different areas of the world and has weakened the dependency of consuming countries and on the other hand, it has affected the changing trend of oil price. In this respect, the present study investigates the causal relationship between oil price and supplying unconventional oil and gas during time period of 2000-2015. Two techniques named Granger technique and Toda and Yamamoto technique have been used to investigate the causal relationship. The results of the research show that in all studying period (2000-2015) the unconventional supply is the strong and direct cause for oil price and the indirect and weak price are introduced as the causes of unconventional supply. Also, based on the results, the strong impact of financial markets on the supply of unconventional resources and oil prices has been achieved. On the other hands the results show that unconventional supply will affect the supply of OPEC in the long term (2000-2015). Therefore, this achievement for OPEC countries, as well as Iran, can be used as a result of a strategic change in production policy.

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.
