Your physics is weak and engineering unstable.
I know how well PV is doing. I don't think we need to put all of our eggs into one basket.
May the best tech win. In the early 1900s, electric vehicles were more common than gas powered cars. Gas took over because the tech was better at the time. That calculation may have shifted in cars, the jury is still out. The jury is back for power generation; solar and wind are better. To finish killing fossil fueled power we still need to generate electricity at night when the wind isn't blowing and this could be a viable option. That's why they built the molten sodium prototype.
Longer term, a former NASA engineer has put forward a plan to ring Yellowstone with geothermal power plants and generate electricity while reducing the threat of eruption. That's a plan worth doing, whatever it costs...
