Iran is ranked first in the world in terms of natural gas storage.Natural gas consumption in Iran has always been growing and there has been no effort to save from Iranian households. Per capita energy consumption in Iran is three times the global average and 13 times that of Japan. In this study, we tried to determine the main factors that affect resedential gas consumption.
