从2002年起,中国就一直闹“电荒”。2003年和2004年春夏,“电荒”越来越严重了。 “电荒”的根源是“煤荒”,即发电用的煤(专业上称电煤)短缺。已有的燃煤发电机组出力不足,加之经济整体对电的需求大增,一少一多就形成了电荒。 我国目前发电机装机容量3.85亿千瓦,2003年全年发电量为1.9107万亿千瓦小时(1千瓦小时=1度电)。其中火力发电占74％,水力发电占16％,核电占5％,其他能源的电力占5％,火力发电,主要就是指燃煤电站。
Since 2002, China has been making “electricity shortages.” In the spring and summer of 2003 and 2004, the “electricity shortage” became more and more serious. The root cause of the “electricity shortage” is the “coal shortage”, which is the shortage of coal used for power generation (professional electric coal). The existing coal-fired generating units have insufficient output, and the overall demand for electricity from the economy has greatly increased. China’s current installed capacity of power generators is 385 million kilowatts, and the total annual power generation in 2003 was 1.9107 trillion kilowatt-hours (1 kWh = 1 kWh). Among them, thermal power generation accounted for 74%, hydropower generation accounted for 16%, nuclear power accounted for 5%, and other energy sources accounted for 5%. Thermal power generation mainly refers to coal-fired power stations.
