Is the potential of geothermal energy starting to turn into growth?
 |
The GEA’s newest report on global growth is an admirable effort on putting on a happy face -- but its numbers tell another story.
The association reports, for instance, that in 2010 geothermal energy generated “twice the amount of electricity as solar energy did worldwide.” The world’s installed grid-connected PV capacity went from 7.4 gigawatts at the end of 2009, to 16.8 gigawatts at the end of 2010, to 29.7 gigawatts of grid-connected PV at the end of 2011.
