1 能源紧缺-人类面临的共同挑战能源,是人类赖以生存和发展的重要战略物资。自世界进入工业化时代后,全球能源消费迅速增长。有关资料显示:1770到1900年,在全球工业化的初期阶段,世界人口增长2倍,能源消费总量增长6倍; 1900到1992年,在全球工业成熟阶段,世界人口增长3倍,能源消费总量猛然增长了75倍;全球能源消费的总量:1970年时为83亿吨标煤,到了2003年达到了140亿吨标煤,估计到2020年时全球消费总量将达到200亿吨标煤。
1 Energy Shortage - Common Challenges Faced by Humanity Energy is an important strategic material for human survival and development. Since the world entered the era of industrialization, the global energy consumption increased rapidly. Relevant data show that from 1770 to 1900, at the initial stage of global industrialization, the world’s population doubled and the total energy consumption increased by 6 times. From 1900 to 1992, at a time when global industry matured, the world’s population increased three-fold. Total energy consumption The total amount of global energy consumption was 8.3 billion tons of standard coal in 1970 and reached 14 billion tons of standard coal in 2003. It is estimated that the total global consumption will reach 20 billion tons by 2020 coal.
