Energy consumption in domestic sector was analysed for a selective north-eastern part of Thailand. 303 families in the region were randomly sampled. They are scattered and cover 14 provinces. All of them were classified into 2 groups namely municipal areas and rural areas. The 150 municipal families and 153 rural families were interviewed. The data were then analysed to determined energy consumption characteristics. The results showed that averaged energy consumption per year-family (ECFavg.) were 17,092.26 MJ/year-family and 16,462.21 MJ/year-family for the municipal and rural areas respectively. For municipal area, 51% of electrical energy, 12% of LPG and 37% of renewable energy were found while families in rural areas consumed 49% of electricity, 1% of LPG and 50% of renewable sources. The data were also plotted to determine the relation between average energy consumption per family (ECFavg.-n) and the number of family member (n). It was found that average energy consumption was in forms of power functions: ECFavg.-n=13,393n0.273 (R2=0.97) and ECFavg.-n=11,625n0.2702 (R2=0.97) for municipal and rural areas respectively. Moreover, energy use per person was found to decrease when number of members in the family was increased.
