Geothermal generation is accomplished by which method?

Geothermal generation uses the Earth’s internal heat to make steam that drives turbines. Engineers access underground reservoirs of hot rock or hot water by drilling wells; near the surface, that heat can appear as natural geysers or hot springs, or it can be brought up by pumping hot water and then converted to steam. That steam powers the turbines to generate electricity. This is different from burning fossil fuels, which would create steam from combustion, and from wind or tidal power, which rely on moving air or water, not underground heat. So the method described—using the Earth’s heat to produce steam near the surface—is the correct approach.
