Found a geothermal potential map of the US.[1] Utah is in a different basin, but Colorado has a nice big hot spot. It's not a fully renewable resource. It's possible to pull out too much heat too and deplete the resource.
The entire geothermal heating of the planet is only 50 terawatts, which seems big, but it's spread over 500 million square kilometers. Or 100KW/km^2, which is not much. Solar is orders of magnitude larger. [1] https://www.britannica.com/science/geothermal-energy |
