Geothermal power generation in the world 2010 2014 update report
We have analyzed the major activities carried out for geothermal electricity generation since WGC2010. New data has been taken from WGC2015 Country Update reports, private communications from IGA members and Affiliated Organizations, and we would like to acknowledge all IGA friends for their valuable help. Other updates have been collected from websites of private and public organizations involved in geothermal development. Plants under construction, which are expected to be commissioned in 2015, are included in the installed capacity. An increase of about 1,7 GW in the five year term 2010 2015 has been achieved (about 16% following the rough standard linear trend of approximately 350 MW/year, with an evident increment of the average value of about 200 MW/year in the precedent 2000 2005 period (Bertani, 2005a, 2005b, 2006, 2007, 2010, 2012 and 2013) 1. INTRODUCTION The total installed capacity from worldwide geothermal power plant is given in tables I and II and in figures 1 and 2. For reaching the forecasting of 2020, based on an accurate accounting of all the existing projects at an executive stage, a clear change in the present linear growing trend should be necessary. In table III data from all the countries currently generating geothermal electricity are presented, with the 2010 and the updated at 2015 values of installed capacity and the produced energy per year, the increment since 2010 both in absolute terms and in percentage, and the aforesaid mentioned short term forecasting to year 2020 for the installed capacity. In figure 3 a world map of the year 2015 installed capacity is presented.
