1994年美国的水能资源开发率已达到可开发利用的80%多,此时美国的水能资源已基本上开发完了,没有继续开发的资源了
这是什么逻辑?80% = 基本完了 = 没有了?看看人家美国人自己怎么说的:
Although there are substantial undeveloped resources in the United States, hydropower's share of the nation's generation is predicted to decline through 2020 to about 6% from about 10% today. The decline is due to environmental issues, regulatory complexity, and energy economics. Energy analysts expect almost no new hydropower capacity to be added through 2020.

我觉得中国大搞水电是不得已的事情,是经济发展的需要。热电、水电、核电,只要有电就好,有电才有钱,环境问题要讲,但是次要的。小平同志说:“发展才是硬道理。”环保人士讲些夸张的话,水电人士没必要气得变成牛二。
