据科学家估计,半个世纪以后,公元2030年,世界人口将比现有的40多亿翻一番,达到80亿左右,对能源的需求将相应增加3～4倍,即从现在相当于80亿吨煤增加到240亿至350亿吨。这样尖锐的矛盾有没有办法解决? 设在奥地利的国际应用系统分析研究所的一份研究报告回答说:“可以办到”,但必须“作出艰苦的努力和付出很高的代价”,各国政府要赶紧作出决定,实现“能源转换”。这是17个国家的140位科学家,花了7年时间的研究得出的结论。报告认为,满足人类能源需要的最大障碍不在于它的资源,而在 According to scientists’ estimation, half a century later, by 2030, the world’s population will double from the current more than 4 billion to about 8 billion, and the demand for energy will be increased by a factor of 3 to 4 times, from the current equivalent of 80 Billion tons of coal increased from 24 to 35 billion tons. Can such a sharp contradiction be solved? A research report from the Austrian Institute of Applied Systems Analysis replied: “It is possible to do that, but it must” make painstaking efforts and pay a high price “. Governments We must quickly make a decision to achieve ”energy conversion." This is the 140 scientists in 17 countries, spent seven years of research concluded. The report argues that the biggest obstacle to meeting the human energy needs is not its resources but
