[摘要]：Since the start of economic reform in 1979, Jiangsu Province has become one of the most developed regions in China. To ensure adequate energy supply and sustainable development of economy and environment, it is necessary to analyze Jiangsu Province's energy balance. The energy flow chart is taken as a useful tool for sorting out and displaying energy statistics data. The purpose of this paper is to draft the Jiangsu Province's energy flow chart for 2009, which is used to study the characteristics of energy production and consumption in Jiangsu Province. We find that: (1) In 2009, energy imported from other regions accounted for 96.1% of the total primary energy supply. However, its energy supply mainly came from coal. (2) Jiangsu thermal power and heating efficiencies in 2009 were higher than those of Guangdong and China in 2007. However, its coal processing and petroleum refineries efficiencies in 2009 were lower than those of Guangdong and China in 2007. (3) Electricity supply in Jiangsu Province mainly depended on thermal power, which accounted for 88.97% of the total electricity supply. However, 96.36% fuel for thermal power was coal. (4) The share of final energy consumption of the secondary industrial sector was 81.28% in 2009. (C) 2011 Elsevier Ltd. All rights reserved. |
