Measuring the Rebound Effects of Energy Carriers Consumption in Iranian Economic Sectors Using Input-Output Approach

Improving energy efficiency as one of the most important tools for managing energy demand leads to a phenomenon called Rebound Effect, which causes the energy savings achieved by improving energy efficiency not equal to the expected level. In this study, with employing Input-Output approach and the structural decomposition analysis, we quantify the changes of electricity, natural gas and oil products consumption according to the final demand variations and technological progress in terms of changes in energy efficiency and intermediate demand during the period of 2001-2011. After examination of the economic sectors in which they experience improving energy efficiency, the rebound effect of the energy consumption for each energy carriers has been measured. The results of this study show that electricity, natural gas and oil products from 24 economic sectors in 11, 4, and 20 economic sectors have experienced improvements in energy efficiency due to technological advances. "Construction of basic metals", "Electricity" and "Manufacturing of non-metallic mineral products" have the highest reduction in energy consumption associated with these carriers respectively, and the "postal and support services" 62.83%, "Construction of coke and products from oil refining and nuclear fuel" with 147.72%, "Construction of chemical and chemical products" with 86.33%  have the highest efficiency in electricity consumption, Natural gas and oil products. Considering inter-sectional and intra-intermediate interchanges, the rebound effects is increased in all sectors.
