A Study On The Household Energy Consumption And Energy Saving And Emission Reduction Effect In Gansu

China’s energy resource reserve has long been dominant by coal. Hence, coal has been a major component in the energy structure in China. However, but household energy consumption structure presents a different development trend. The household energy consumption evolution trend was analyzed in the article from the three dimensions including national, Gansu Province and urban-rural contrast. In addition, the natural factors and socio-economic factors of household energy consumption evolution was studied through using energy statistical data from1980to2010. Moreover, the model of energy saving and emission reduction was simulated by vsing the IPAT mode based on energy consumption prediction in the next20years in Gansu. Finally, countermeasures and suggestions was put forward for the development of energy consumption in Gansu ProvinceConclusions drawn from the study are as follows:Firstly, the proportion of household energy consumption over total energy consumption at national level decreased from18.4%to11.0%during the period of1980to2009, but the total household energy consumption and per capita consumption showed an upward trend during the same period. The energy consumption structure was characterized by an increase in the proportion of clean energy, a rapid decline in the proportion of coal, diversified by new and renewable energy, and co-existence of different energy development.Secondly, the terminal household’s living energy consumption at the provincial level increased gradually year by year, and kept the same change trend as the national total household energy consumption, but the growth rate was much higher than it is at the national level. The national total household energy consumption increased by0.9times from1985to2009, while an increase of5.09times in Gansu Province. Urban area used more commercial energy at both national and the provincial level, including coal, gas, oil, natural gas, electricity and heat, while non-commercial energy was only solar. It indicated that about70%of rural household energy was biomass energy, and that the kinds of commercial energy consumption in rural household comprise only coal, oil and electricity, but non-commercial energy played an important role in family life of rural residents.The development trend of household energy was affected by many factors in Gansu Province. The energy consumption structure has correlation with household’s income. Urbanization and population contributed highly to household energy consumption structures and their correlation coefficients are0.819and0.558, respectively.The Environmental Constraints Model was one of the most suitable models for economy-energy-environment coordinated development in Gansu Province. According to the analysis results by using the ECM Model, the total carbon emissions in Gansu showed a continuous growth trend, but the growth rate was very small. Compared with the Business And Usual model, the ECM Model could save energy about3099.9×104tce, reduce carbon emission about2509.8×104t, and achieve emission reduction targets by40%-45%. The optimization of energy structure is mainly reflected in energy intensity and change trend of total carbon emissions.New energy must be developed in order to achieve a low-carbon economy from the perspective of optimization of energy structure, but the current technology, cost and investment system limited the industrialization and intensified development of new energy. In addition, progress and development of energy technology in the short term have a significant impact on wind power, solar energy, biogas industry and clean use of high-carbon energy.
