基于能流图的山东省能源消耗分析

Using Energy Flow Chart to Analyze Energy Consumption in Shandong Province

随着工业化和城市化进程的加快,山东省能源消耗量逐渐增大,2008年山东省能源消耗占全国的11.3%。因此研究山东省能源消耗对促进节能减排有重要的意义。能流图可以直观、形象地展示能源流动情况,在国际上得到广泛的应用。能源统计数据是能源分析的基础,但我国的能源统计体系与国外有较大区别。按国际准则的能源供需体系和有关专家的意见,适当调整了山东省能源平衡表。本文的主要目的是绘制山东省2008年能流图,在此基础上分析山东省能源现状和能源利用效率。得到如下结论:①煤炭是山东的主要能源,占一次能源供应的71.84%;②山东省电力以火电为主,火电占总发电量的99.9%;③山东省2008年能源利用效率约为35.83%;④工业部门能源消耗占终端能源消耗的74.9%。进一步说明能流图不但能够直观、定量地展示能源供应、转换和使用数量的全貌,而且可以揭示各个环节的能源利用效率水平。

Along with the rapid process of industrialization and urbanization,energy consumption in Shandong province increases gradually,which accounted for 11.3% of the total China＇s energy consumption in 2008.Thus it is very necessary to analyze Shandong province energy situation in order to save energy consumption and reduce GHG emission.Energy flow chart,as a useful tool for sorting out and displaying energy statistics data,has been widely used in the world.Energy statistics data is the premise and foundation for analyzing energy situation.However,there exit many differences between China＇s and foreign energy statistical systems.Based on the international criterion of energy balance and some advice given by related experts,this paper properly adjusts Shandong energy balance.And the purpose of this paper is to draft a Shandong energy flow chart for 2008,which is used to study the characteristics of energy production and consumption in Shandong.We find that： ① coal is the main energy in Shandong,which accounted for 71.84% of the total energy supply in 2008;② thermal power accounted for 99.9% of the total electricity supply;③ energy utilization efficiency in Shandong was about 33.23% in 2008;④ in 2008,the industrial sector consumed about 74.9% of final energy.We also find that the energy flow chart is not only an object and quantitative tool for showing a whole picture of energy supply,transformation and end-use data,but also can reveal the energy utilization efficiency.
