在本文的前半部分(2011年第3期第46页)中,我们分析了目前可替代能源在世界范围的发展形势,其结果并不乐观。所以要解决世界能源需求快速上涨所带来的压力,其途径并不是寻找新的方法来生产更多的能源,加拿大的焦油砂和墨西哥的海湾钻井,都给我们脆弱的生态系统带来了很大压力,因此,我们应当从节能和提高能源使用效率方面入手来减少对能源的需求。实现节能和高效需要转变生活方式 In the first half of this article (Issue 3, 2011, p. 46), we analyzed the current situation of alternative energy sources in the world. The result was not optimistic. So instead of looking for new ways to produce more energy, the pressure from the rapidly rising energy needs of the world will come under pressure. The tar sands in Canada and Gulf drilling in Mexico are all contributing to our fragile ecosystems Therefore, we should start with energy conservation and improve the efficiency of energy use to reduce the demand for energy. To achieve energy-saving and efficient need to change the way of life
