New hybrid automobiles, pioneered by Toyota, use both gasoline and electric power to boost gasoline efficiency by approximately two-fold. A massive changeover to more fuel-efficient vehicles would make a big difference, especially as the numbers of vehicles on the road soars in China, India, and other developing countries.
技术的进步可以让我们从这一桎梏中摆脱出来，但前提是我们必须未雨绸缪。有两种技术看起来最有前途。第一种是通过使用更高燃料效率的汽车来节省能源。由丰田率先推出的混合动力汽车，能使用汽油和电能，从而将汽油的使用效率提高了近两倍。向有更高燃油效率的车辆的大规模转变会使局面大为改观。特别是在中国、印度等汽车数量大的发展中国家。
