JAUE2022-097: Sensitivity Analysis of the Characteristics on Urban Household Kitchen/Hot Water Energy Consumption in China

Abstract

China is in a stage of rapid urbanization; household energy consumption and carbon emissions are facing huge growth pressure. The level of household energy consumption reflects the living status and quality of life of residents to a certain extent. With the increasingly rich material and cultural life of urban household, resideants' demand for energy consumption will further increase. Kitchen/hot water is one of the most important activities in family life, and the total energy consumption continues to increase. Based on the data of energy consumption in urban areas, a numerical calculation model of end-use energy consumption was established to analyze the spatial distribution differences and characteristics of kitchen energy consumption in urban households in 30 provinces. The results show that "gas + electricity" is the main energy consumption mode of kitchen/hot water in all provinces. In Guangdong, Sichuan, Henan, Jiangsu and Zhejiang, the total kitchen energy consumption exceeds 950PJ, accounting for 40% of the national total. In addition, we tried to use Pearson correlation coefficient to discuss the influencing factors of kitchen/hot water energy consumption and found that the total urban population and the number of households have a significant positive correlation with the energy consumption of kitchen/hot water
