Geothermal power plants extract energy from hot water deep underground, often using steam to power turbines that in turn, generate electricity. They emit no greenhouse gasses and can operate 24/7, forming a major part of certain counties’ green energy mix, such as Iceland and Kenya . 

There is more energy stored as heat in the Earth’s crust than in all fossil fuels and fissionable materials combined. Theoretically, geothermal power could supply far more than humanity’s total energy needs. However, in 2020, geothermal energy provided only about 0.5% of global electricity generation. This is because traditional geothermal wells are drilled into natural steam reservoirs, which exist in a relatively small number of places around the world. 

Geothermal generation could become a major global energy source, especially thanks to the development and adoption of several emerging technologies that aim to harvest heat from dry rock, often from deeper in the crust than traditional geothermal wells. Yet unwieldy regulation, long permitting processes and a lack of funding currently stand in the way.

If you live somewhere where there are untapped geothermal resources, consider asking your political representatives to invest in and streamline the buildout of geothermal generation.
