projected total energy demand. The gap between total energy demand (which reaches about 2.5 x 1012 gigajoules per year in 2100) and fossil fuel demand corresponds to the use of nuclear, terrestrial solar, and hydroelectric sources. Figure 7 shows GNP per capita, in thousands of 1975 US $, versus time in years, starting from 2000, for each of the nine regions, together with the world average GNP per capita. The abbreviations on the horizontal axis refer back to the aggregates of countries in the section on Energy and GNP. The numbers on the bar graph refer to per capita GNP values of the appropriate group of nations for the year 2100. Well into the twenty-first century, the Middle East seems to have the largest per capita GNP, while South and East Asia has the lowest value of about US$ 11,000 per capita; world average (referred to as TOT) is about US$ 29,000 per capita. The disparity between the wealthiest and poorest groups of nations reduces from a factor of 39 to a factor of 12 between now and the next century.
