For starters, the manufacturing process that produces electric cars – especially their batteries – requires an enormous amount of energy, most of it generated with fossil fuels. A life-cycle analysis shows that almost half of an electric car’s entire CO2 emissions result from its production, more than double the emissions resulting from the production of a gasoline-powered car.
首先，制造电动汽车的生产过程——特别是电池的生产过程——需要大量能量，其中大部分来自化石燃料。生命周期分析表明，电动汽车的二氧化碳排放总量中有近一半产生于生产过程，是汽油动力汽车生产过程排放量的两倍多。
