Study On The Transition Of Household Energy Consumption To Clean And Low Carbonization

China’s residential energy consumption has become the second largest energy consumption area next to industry.In recent years,more and more attention has been paid to the empirical research on residential energy consumption and the discussion on energy conservation policies.In this thesis,micro and macro research methods were combined to carry out the structural analysis and sustainability research of Wuhan residents’energy consumption.The research results can provide reference for promoting the clean and low-carbon energy consumption transformation work of this city.Based on the detailed field investigation,this thesis firstly applies a quantitative analysis to the residents’energy consumption,then through direct and indirect energy consumption decomposition,residents coal burning pollutants estimates,the future energy consumption scenario forecast of residential construction sector and residential traffic sector by LEAP,structural decomposition of the IPAT model for the intrinsic role of social factors in environmental greenhouse gas emissions and so on,the influences of residents’energy consumption with the respect to economy,environment and society are analyzed in comprehensive sustainability.The main research results of this thesis are as follows.The per capita energy consumption of community residents and rural residents in Wuhan is 0.178 tons of standard coal per year and 0.197tons of standard coal per year respectively,while the total direct energy consumption is about 1.6 million tons of standard coal.The indirect energy consumption of the residential sector was about 14.63 million tons of standard coal for urban residents and about 3.07 million tons for rural residents.Indirect energy consumption is far greater than its direct energy consumption.In the analysis of carbon emissions and the corresponding harmful gases,it is found that the direct carbon emissions and indirect carbon emissions of the residential sector are about 558.3 thousand tons and 4.43million tons;Pollutants produced by the combustion of scattered coal are about 512.38 tons of SO₂,714.60 tons of NO_x and 1948.74 tons of particulate matter emission.By scenario analysis,the energy consumption of residential buildings and residential transportation sectors in Wuhan in the future is predicted.It is found that,compared with the baseline scenario,the maximum energy saving potential of residential construction sector under low-carbon scenario can reach 1.39 million tons of standard coal,and that of residerntial transportation sector can reach 3.07 million tons of standard coal.The main adjustment factors include:to increase the proportion of energy-saving renovation of existing buildings,to promote the use of energy-saving electrical appliances and to strictly control the energy consumption per unit area of new buildings;To control the growth rate of private cars,strengthen public transportation,reduce the energy consumption of transportation equipment and improve the proportion of electronic transportation equipment,etc.According to the IPAT model and the Kaya identity,this thesis decomposed the LEAP model simulation results,and found that among the factors such as population,affluence and technology,the main promoting effects of greenhouse gas emissions are population effect and economic effect,while the main inhibiting effects are energy intensity effect and carbon intensity effect.The economic effect and energy intensity effect are the most significant.Under the low-carbon scenario,greenhouse gas emissions will be promoted and reduced by50.9 million tons of CO₂ equivelent and 47.5 million tons of CO₂ equivalent,respectively.
