Here&#x27;s an excellent podcast that goes in depth on the potential of enhanced geothermal of the same sort described above. Essentially they drill two holes and then frack the rock between them. This makes it possible to setup geothermal in many more places. <a href="https:&#x2F;&#x2F;api.substack.com&#x2F;feed&#x2F;podcast&#x2F;74977669&#x2F;bb712d64d007e4241c8b169493b6776b.mp3" rel="nofollow noreferrer">https:&#x2F;&#x2F;api.substack.com&#x2F;feed&#x2F;podcast&#x2F;74977669&#x2F;bb712d64d007e...</a>

For reference:<p>3.5MW is a single largish wind turbine.<p>PV solar is ~200W&#x2F;m2, so 17,500 square meters of solar panels.<p>A single nuclear reactor is commonly &gt;1GW (1,000MW).

Geothermal wells often cool down and become ineffectual with time.<p>A starting temperature of just 180C doesn&#x27;t sound very promising either. Normally the higher the temperature the more energy you can extract and the faster you can extract it with a given amount of water&#x2F;turbines&#x2F;pipes.
