摘要
以替代石油产品、解决汽车用能为分析基点,对"建设燃煤电站、发展电动汽车"方式相对于"以煤制油产品替代传统燃油汽车的石油产品消费"方式在能源综合利用效率和汽车动力能源生产环节(燃煤发电或煤制油)的水资源消耗需求情况,进行了粗略的分析比较。结果显示"燃煤发电+电动汽车"在2个方面均具有明显的优势,尤其是采用空冷机组的情况下,"燃煤发电+电动汽车"方式的水资源节约效果显著。
With a view to replace the petroleum products and solve the problem of energy supply for electric vehicles, this paper made a rough comparative analysis on two development modes： one is constructing coal-fired thermal power plants and developing electric vehicles, and the other is substituting coal liquefaction products for petroleum products for conventional oil-fueled vehicles. Based on this, a brief comparison is made between the two modes in the aspects of overall efficiency of energy utilization and water consumption in the process of vehicle power source production. The result shows that the ＂coal-fired-generation-plus-electric-vehicles＂ mode is much more superior in both aspects, and that its water saving effect is especially prominent in the case of air-cooling units.
