During the past century both the world population and energy consumption have increased substantially. The population has grown four-fold in one hundred years, and now exceeds 6 billion. The energy consumption has grown 9.5 times, from 0.9*109 T.O.E. (tons of oil equivalent) to 8.55*109 T.O.E. The information in Fig. 1 reflects the dynamics of consumption of different energy sources in the world. From 1850 to 1950, the main source of energy has been coal. In 1920, the percentage of coal in the world energy balance reached 74%. In spite of rapid development of the petroleum industry, the percentage of oil has never exceeded 47% (1972). The proven reserves of oil of 142.1*109 tons [1] is sufficient to last 40 years. At present, the percentage of oil and gas in the world energy balance is approximately 65%. The percentage of natural gas in the energy mix is approximately 25%, about the same as coal.
