Unfortunately this pattern in the most energy exporters has not been observed; therefore these countries generally have low energy efficiency. This disquisition is up to answer this question: Have the raise in the price of oil had a meaningful effect on Iran`s energy intensity? To do so, yearbook data from 1980 till 2008 has been used. The results of this scrutiny show that the raise in price of oil has made government improve their technical systems and establish a logical economy and a more rational method in management of energy consumption.
