At the same time, it was disturbing to note that proved oil reserves increased by only 1 per cent to cSS gigatonnc. Since 1970, proved oil reserves have been reviewed upwards by about 6 per cent, while annual oil production has increased by 33 per cent. These figures support the findings, published in the World Energy Conference-Conservation Commission Report on Oil Resources, 1985-2020 (August 1977), that the annual rate of growth of world oil reserves is decreasing. World oil production is expected to peak at 4 to 5 gigatonnc a year by 1990, declining to 3.4-4 gigatonnc a year by 2000. Since oil currently meets almost half the world's total energy needs, by any reasonable estimates for world economic growth a serious shortfall in world energy supply can be expected before 2000. Consequently, all recent major reports on the world energy outlook have pointed out that the future balancing of energy supply and demand will require: • Major conservation efforts to reduce the ratio that now exists between the growth of demand for energy and growth of the economy, and • A very extensive changeover to coal and nuclear power. A second publication, the World Energy Conference-Conservation Commission Report on Coal Resources, 1985-2020 (August 1977), states that coal could contribute substantially to future energy supplies and that world coal production is expected to more than double by 2000. However, the World Energy Conference expects that less than one-tenth of the production will be exported by producing countries. In thermal values, this export trade will be equivalent to about one quarter of the world's present oil trade. It would seem, in consequence, that * Giualonne = one thousand million tonnes. coal imports arc unlikely lo become a major source of energy in countries wflh no economic coal reserves of ihcir own. It should be noted llial known coal deposits arc not distributed evenly — collectively, ten countries possess a total of 92 per cent of the world's economic coal reserves. The proportion of primary energy needs met by both natural gas and re- newable energy sources is expected to remain constant during the next few decades. Also in this period no major contribution is expected from alternative energy sources, such as solar, wave and tidal power. As with coal, known uranium deposits are unevenly distributed around the world. On the other hand, a very large amount of energy can be transported in a small volume of nuclear fuel and this feature will facilitate international trade in uranium. Nuclear power is expected lo account for more than one-third of the world's total electricity generation by 2000.
