A Study of Energy- saving Behavior in Major Iranian Industries

The present study aims at investigating into the Devisia Decomposition Methods as applied to the three energy carriers including electricity; natural gas; oil derivatives and total energy consumption in major Iranian industries in general. It also seeks to analyze the production and structural factors and pure intensity factor in the changes in the ultimate energy consumption from 1979 to 2001. The findings of the study show that production effect in explaining the changes of electricity consumption, pure intensity effect in explaining changes in natural gas consumption as well as production effect and pure intensity in explaining the changes in the consumption of energy carriers of oil and the whole energy use played the dominant role respectively both before and after 1989. Structural effects were shown, in all the four cases mentioned above, to have a share, though a slight one, in explaining the energy consumption behavior. Moreover, as to the consumption of the carriers and that of the whole of energy in Iranian major industries, the findings indicate that structural changes have led to the reduction,however small of the consumption of energy.
