1.RAMVBUCapability2.RAMVDriveCharacter3.MVDriveEnergySaving4.IntelligentMotorControl39我国能源面临的问题我国能源面临的问题人均能源资源相对不足,资源质量较差,探明程度低。

人均煤炭探明可采储量仅为世界人均平均值的1/2,石油仅为1/10能源生产消费以煤为主。

原煤在能源消费结构中所占比重为75.6%,给环境保护带来极大压力能源工业技术水平低下,劳动生产率较低。

我国煤炭工业职工总数占世界52%,但煤炭产量占世界总产量21.5%,人均年产煤量仅为世界其他产煤国总计的人均年产煤量的1/5能源资源分布不均,交通运力不足,制约能源工业发展。

能源资源西富东贫,给能源运输带来压力,运力不足造成煤炭积压,制约煤炭工业发展,也造成电力供应不足能源供需形式依然紧张。

能源缺口大,拉闸限电,成品由价格上涨,煤炭供应不足能耗水平高,能源利用率低下。

能源系统的总效率不及发达国家的一半,工业产品单耗比工业发达国家高出30%~90%能源环境问题日趋严重,制约经济社会发展。
