第10题
The crucial question at the beginning of the 1990's is whether the trend that began in the 1970's will prove to be temporary or permanent. Is the era of cheap energy really over, or will a combination of new resources, new technology and changing geopolitics bring it back? One key determinant of the answer is the staggering scale of energy demand brought forth by 100 years of population growth and industrial demand.
Except for the huge pool of oil underlying the Middle East, the cheapest oil and gas are already gone. Even if a few more giant oil fields are discovered, they will make little difference against consumption on today's scale. Oil and gas will have to come increasingly, for most countries, from deeper in the earth and from imports whose reliability and afford-ability cannot be guaranteed.
