The BIGGEST problem with clean energy

It is estimated that there is enough geothermal power potential in the Western US to supply the entire country. A geothermal plant is a fraction of the cost to build compared to nuclear and also a fraction of the physical footprint. Also no deadly waste building up or dangerous radiation to clean up and decommission.
Nuke plants are very expensive to build, take 10 years or so to build, have a very large physical footprint,  and when they go wrong, they go wrong VERY badly. And the carbon footprint of the construction process of a nuke plant is huge even if their operation has a very small footprint.
Geothermal should be looked into more.
Wind, solar and such also need more development
