The authorities should focus not only on producing renewable energy, but also on improving the energy efficiency of existing systems. As it stands, China’s economy is about three times as energy-intensive as America’s (a country that is not particularly energy-efficient itself).
尽管如此，中国应该加大行动力度。当局的重点不但应该包括生产可再生能源，还应该包括改进现有体系的能源效率。目前，中国经济的能源密集程度大约是美国的三倍（而美国本身的能源效率并不十分出色）。
