Why is geothermal energy not being used everywhere?

Answer 1

There's really only one reason why geothermal energy isn't used everywhere: not everywhere on the planet has some measure of geological activity, which is required for the potential of geothermal energy to exist.

Underground reservoirs of water are heated by geological activity, such as earthquakes and volcanoes. This water turns to steam and expands. It is the force this steam can exert through its own natural convection that geothermal activity taps into to generate energy.

Therefore, geothermal couldn't be done in areas that aren't geologically active, such as the Sahara Desert.

Answer 2

Geothermal energy is not being used everywhere because it is location-specific, requiring access to hot rock formations or geothermal reservoirs which may not be present in all areas. Additionally, the upfront costs of geothermal energy development can be high, making it less attractive compared to other more readily available energy sources in some regions. Finally, the technology for harnessing geothermal energy is still evolving, requiring more research and development to make it more widely accessible.
