Pike Research forecasts global geothermal power capacity could more than double by 2020; US to lead world in geothermal power capacity through 2020

Escalating investment in geothermal power could result in a 134% increase in global geothermal capacity between 2010 and 2020, from 10.7 gigawatts (GW) to 25.1 GW, under a high-growth forecast scenario, according to a report by Pike Research. Under a more conservative business-as-usual forecast scenario, Pike estimates that geothermal power... Read more →
