Description:
This paper calculates energy efficiency and exergy efficiency of household energy utilization in rural China. Provincial energy efficiencies and exergy efficiencies for space heating sector, cooking sector and hot water sector are calculated and analyzed. Result shows that national energy efficiencies in space heating, cooking and hot water sector are 27.43, 15.32 and 13.11%, respectively. Exergy efficiencies are 1.63, 4.42 and 1.16%, respectively. Energy efficiencies in Xinjiang, Tianjin, Beijing and Shanxi are higher than other provinces because of the wide utilization of coal. In eastern China like Shanghai, Jiangssu, Fujian, the proportion of biomass is quite large which results in a low efficiency. Furthermore, exergy efficiencies in southern China are much higher than those of northern China because of the climate differences.
