人类一百多万年进化发展的过程,就是一部不断向自然索取更多能源的历 史。按现在的开采水平估计,世界上的煤、油、天燃气资源在几十年内逐渐枯 竭,并带来严重的环境污染问题,从而造成冰雪消融,冰川退缩,全球气候变 暖。能源短缺和环境保护是21世纪经济发展和能源领域最重要的课题。 纵观人类利用能源的历史,可以清楚地看到,每一种新能源的发现和利用, 都把人类支配自然的能力提高到一新的水平。走进新世纪,能源科学技术将会 有怎样的突破? The evolution of mankind over a million years is a history of constantly seeking more energy from nature. According to the current exploitation level, the world’s coal, oil and natural gas resources are gradually depleted within a few decades and bring about serious environmental pollution problems, resulting in ice melting, glacial retreat, and global warming. Energy shortages and environmental protection are the most important issues in the economic development and energy sectors in the 21st century. Looking at the history of human use of energy, we can clearly see that the discovery and utilization of each new energy source all take mankind’s ability to dominate nature to a new level. Into the new century, energy science and technology will have what kind of breakthrough?
