Cumulative global geothermal power capacity in MW Table 39 Geothermal Power Production and Installed Capacity, 2000 Source: Huttrer. Global installed geothermal electric capacity has been steadily growing, with about 3.9 GW in 1980, 4.8 GW in 1985, 5.8 GW in 1990, 6.8 GW in 1995 and almost 8 GW in 2000. The annual growth rate has been around 5%. More recently, Asia and Central and South America have shown particularly strong growth in relative terms. These are also the areas where geothermal power can play a significant role in the energy balance: the share of 6 GEOTHERMAL POWER Production in TWh Installed capacity in MW USA 15.5 2,228 Philippines 9.2 1,909 Mexico 5.7 755 Italy 4.4 785 Japan 3.5 547 Indonesia 4.6 590 New Zealand 2.3 437 Rest of world 4.1 723 Total 49.3 7,974 9000 8000 7000 6000 5000 4000 3000 2000 1000 0 Figure 50 Worldwide Development of Geothermal Electric Power 1904 1914 1942 1950 1960 1970 1975 1980 1985 1990 1995 2000 Sources: Lund and Huttrer. 133
