چکیده:
The purpose of this study is to investigate the role of oil, natural gas and coal consumption in Iran’s economic growth during the periods from 1980 to 2012. The stationary analysis is performed by using ADF and Phillips-Perron unit root test and Auto-Regressive Distributed Lag (ARDL) approach was used to test for co-integration between the variables. The findings show that the variables are cointegrated; it means there is a long-run equilibrium relationship between the consumption of energy and economic growth. Accordingly the consumption of natural gas and coal was concluded to have positive and significant effect on economic growth, while the consumption of petroleum shows no significant effect on economic growth.

3. Literature Review Behnameh (2011) investigated the causal relationship between coal consumption and economic growth in Iran.
On the other words, there was neither a long-run nor a short-run relationship between these two variables namely; the increase in coal consumption had no effect on economic growth.
They concluded that there is a long run relationship between these variables so, the natural gas consumption, capital, export and labor force have a positive effect on economic growth.
(2014) used the Granger causality and the co-integration tests to examine the relationship between the consumption of crude oil and economic growth in Latin America.
4. Model Specification The following model is specified to analyze the empirical results and study the relationship between economic growth and its effective factors including oil consumption, natural gas consumption and coal consumption, according to the previous studies, particularly those by Bildirici and Bakirtas (2013).
The results derived from both tests show that none of the variables are of order I(2) and economic growth, oil consumption, natural gas consumption and coal consumption variables become stationary after first differencing.
The role of oil, natural gas and coal consumption in economic growth of Iran has been discussed in this study.
Our findings are consistent with those of Yoo (2006), Apergis and Payne (2009), Cheng and Lai (1997), Li and Leung (2012), Yuan et al.
