Worldwide geothermal data were comprehensively collected for reporting at the World Geothermal Congress 2010, held on 25-29 April 2010, in Bali, Indonesia (Bertani, 2010; Lund 2010). In 2011 and 2012, these 2010 data were carefully assessed, with the global results published by Bertani (2012) and Lund et al. (2011). Twenty-four countries were producing electricity from geothermal resources, with a total geothermal installed capacity exceeding 11,079.3 MWe, with electricity generation of 67,954.3 GWh, based on 2010 data (Bertani, 2012), updated with 2011 GIA Country Member data (Figure ES2, Table ES1). In 2011, the 9 GIA Member Countries having geothermal generation contributed about 63% of the global installed geothermal capacity, and 61% of the total geothermal power generated.
During the period 1950 to 1970 the worldwide geothermal installed capacity growth rate was quite small, then began to accelerate following the energy crisis of the early 1970s, increasing by a factor of >6.5 between 1970 and 1985. Between 1985 and 2005, the worldwide geothermal installed capacity increased by a factor of about 2.3, at a very uniform rate of ~210 MWe/yr (Figure ES2). However, between 2005 and 2011, the rate of increase grew significantly, with a linear trend of about 352 MWe/yr to the end of 2011; more than 1.7 times the rate of the previous 5 year period. The capacity increase in GIA Member Countries was: 2011 (6,975.3 MWe) – 2005 (5,449 MWe) = 1,526.3 MWe, or about 28% (4.7%/yr). Table ES1 presents the 2011 data for GIA Member Countries and 2010 data for the other 15 countries with geothermal power generation (Bertani, 2012). Table ES2 illustrates the growth in installed capacity (1950-2011) and generation (1995-2011), with 2006, 2007, 2008, 2009 and 2011 representing minimum estimates.
