去年秋季,联合国教科文组织曾在津巴布韦首都哈拉雷召开国际能源大会,汇集全世界各国代表共同商讨人类面临的一个重要问题——能源资源的日趋短缺与地球人口不断增加之间的矛盾。从而提出一个新的课题:以可再生能源替代传统的矿物能源。于是,一个崭新的概念——“阳光经济”出现了。 世界上耗能最大的美国,最近宣称将于2010年以前在50万幢建筑屋顶上安置强大的光电池发电系统,以大大减少建筑物对传统能源的依赖。虽然美国拥有丰富的矿物能源资源,但美国人并不肆意开采,他们要
Last fall, UNESCO held an international energy conference in Harare, the capital city of Zimbabwe, to bring together representatives from all over the world to discuss an important issue facing mankind - the contradiction between the increasing shortage of energy resources and the increasing population of the Earth. Therefore, a new topic is proposed: Replacing traditional mineral energy with renewable energy. As a result, a new concept, “Sunshine Economy,” emerged. The United States, which has the largest energy consumption in the world, recently announced that it will install a powerful photovoltaic power generation system on the roofs of 500,000 buildings by 2010 to significantly reduce the building’s dependence on traditional energy sources. Although the United States has abundant mineral energy resources, Americans do not want to exploit it. They want to
