| Abstract |
We have analyzed the major activities carried out for geothermal electricity generation since WGC2005. New data has been taken from WGC2010 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 2010, are included in the installed capacity. An increase of about 1.8 GW in the five year term 2005-2010 has been achieved (about 20%), 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 and 2007). |
