Geothermal Power Generation - A Game-Changing Breakthrough

Geothermal wells cost a lot to drill and even at temperatures of 150 degrees Celsius, the heat energy recovered from them is only sufficient to produce a modest amount of electricity. High capital costs to drill the well, at relatively low electrical power output, results in pretty expensive electricity when you factor in the upfront cost of drilling the geothermal well. For this reason, geothermal electricity generation has outperformed wind and solar on a cost per megawatt basis,. Only in locations where there's volcanic activity close to the surface.
