A New Model for Subdividing End-Use Energy Consumption Based on Household Characteristics and Climate

The rapidly growing household energy consumption has put huge pressure on coping with global warming and the low-carbon transition of cities in China. Household energy consumption was obstruction to achieve sustainable energy development. This paper establishes a new subdivide model based on the household characteristics, economic level of residents and climate conditions, and its will effectively subdivide household energy use into five end-uses: Cooking/hot water, heating, cooling, lighting, and power. The calculation results reveal that the energy consumption of end-use and its provincial differences in urban areas of China. For the country as a whole, (1) Five end-uses energy consumption has maintained a consistent increase over the past decade, and the share of cooking/hot water has expanded significantly; (2) Heating and Cooking/hot water dominate household end-use energy consumption, accounting for over 70% of the total. From the provincial, (3) End-use energy consumption of urban households varies widely by province, cooling energy consumption is concentrated in southern urban China. (4) Where climatic conditions are an important factor in the difference between heating and cooling energy consumption; The difference in cooking/hot water and power energy consumption results from the number of households. This paper provides a basis for accounting for household end-use energy consumption, which will contribute to a cleaner transformation in energy consumption structure.
