These innovations could dramatically increase the geographic reach of geothermal energy and, in certain locales, help address a critical challenge for renewables: providing baseload or readily dispatchable power. Wind power dwindles when winds are not blowing. Solar power takes the night off. With subterranean resources flowing 24-7, without interlude, geothermal production can take place at all hours and under almost any weather conditions. Geothermal is reliable, efficient, and the heat source itself is free.
