Assuming the same capacity growth rate through 2030, the global geothermal capacity installed by 
then could be about 25,000 MWe. Additional capacity can be expected to come from the current front 
runners (USA, Mexico, New Zealand, Japan, and Iceland), as well as from some European countries 
(e.g., Italy, Greece, Balkan countries), Turkey and its eastern neighbors, and several Middle Eastern 
countries, such as Yemen. Australia and some South Pacific island states also may be able to utilize 
their hydrothermal resources for power generation.
Looking to 2050, significant additions in installed capacity also can be expected in the following 
countries and regions:
