Abstract :

Shortage of energy sources - especially fossil fuels, which is our main sources of energy, made many researchers consider the issue of improving energy efficiency and decreasing energy intensity in different industries in recent years.      In this paper, energy use in Tehran Cement Industry Group has been decomposed into three levels of structural, output and net energy intensity changes, during 1996-2006 by using special fourfold method for analyzing the intensity of energy use. Results show AVE_PDM1 model is the best model for having minimum residues and showed that structural changes has the least effect on the changes in energy uses, while output and net energy intensity changes affect the changes in energy uses most.      We can conclude that although effective measures have been taken in decreasing energy intensity and as a result increasing efficiency in Tehran Cement Industry Group, they have failed in different periods due to the inflexibility of production function.
