Jiangsu is one of the provinces in China that have great population density and fast economic development. Therefore it is important to ensure large quantity of stable and high-quality energy supply for its development. With the development of the economy, the demand for energy is increasing very fast while the energy supply is going short. The supply of the local primary energy is only 23% of the demand. The final energy consumption reaches 78 Mtce (1 tce = 7,000,000 kcal), among which the industry and construction account for 78%. Though the total consumption is large, the energy consumption per capita is only 1.13 tce ,the electricity consumption per capita 1017kW, and the household electricity consumption per capita is 138kW. Coal accounts for about 76% of the total energy consumed. This paper discusses utilization ratio of energy and the serious pollution caused by energy consumption. (C) 2002 Elsevier Ltd.
