We could therefore achieve huge reductions in CO2 emissions by converting to small, lightweight, battery-powered vehicles running on highly efficient electric motors and charged by a low-carbon energy source such as solar power. Even better, by shifting to electric vehicles, we would be able to use cutting-edge information technology to make them smart – even smart enough to drive themselves using advanced data-processing and positioning systems.
因此，我们可以使用又小又轻、以电池作为能源的汽车，采用高效的电动马达，使用太阳能等低碳能源。更妙的是，使用电动汽车，我们可以用高精尖信息技术使它们智能化，甚至通过高级数据处理技术和定位系统实现自动驾驶。
