| As the source of economic development,energy is the lifeblood of the national economy.The sustainable development of energy is of vital importance to the long-term sustainable development of China’s economy.The issue of sustainable development of energy and its diversity has always been a hot topic for government and scholars.topic.With the rapid development of China’s economy,the acceleration of urbanization and the gradual increase of economic volume,China’s demand for energy is also growing.China’s consumption of traditional fossil energy is still high.However,traditional fossil energy is not renewable in the short term.The consumption of these energy sources will lead to environmental pollution,climate change and a sharp decline in reserves,while large-scale development and utilization will be new.The problem of energy to replace traditional fossil energy and huge technical obstacles further reduces the ability of energy sustainable development.The superposition of these factors makes how to enhance the sustainable development of energy has become an important strategy at the national level.Exploring the development of more new energy and renewable energy has become an important measure to promote sustainable energy development.These measures make China’s energy system more diverse in energy types,and energy differences are more obvious.Energy options account for the total energy.The proportion of consumption is more reasonable.The diversity of energy systems can make energy supply more stable,reduce the risk of disruption or supply instability in the operation of energy systems,reduce the negative impact of energy consumption on the environment,and improve the stability and sustainability of economic and social development.Promote the sustainable development of the energy system as a whole.First of all,this paper introduces the connotation of energy diversity and energy sustainable development in this paper,puts forward the measurement methods of energy diversity and energy sustainable development,and analyzes the mechanism of energy diversity on energy sustainable development.Panel data clustering analysis was conducted for each energy option consumption of 35 representative countries and regions from 2000 to 2017,and the energy consumption patterns of different countries and regions were obtained.Then,the MDA analysis model framework of China’s energy diversity model based on the concept of sustainable development isconstructed.Based on this,a comprehensive evaluation model of China’s energy sustainable development based on entropy weight method and multi-objective diversity analysis method is established.China’s 2000-2017 energy statistics quantify China’s energy diversity index and energy sustainability level,and obtain energy system diversity and energy system sustainable development levels.Using the methods of situation analysis and quantitative evaluation to analyze the different levels of sustainable energy development indicators and diversity indicators under different value orientations,obtain the comprehensive level of sustainable development of China’s energy system under different conditions,and adopt sustainable energy development in China.The comprehensive level is compared to obtain an appropriate reduction in the proportion of coal and oil consumption in total energy consumption,appropriately increase the proportion of natural gas consumption in total energy consumption and significantly increase the consumption of electricity and other clean renewable energy in total energy.The proportion of consumption can raise the conclusion of the comprehensive level of sustainable development of China’s energy system.Finally,based on the conclusions of this paper,we propose targeted policies for China’s energy diversity model. |
