Thermal solar isn't going to get cheaper over time.
Give me one example of something that isn't computer or consumer electronics based that has gotten cheaper over the years?
That plant is all material and labor cost which are not going to go down in price.
A 2 billion dollar power plant that is only able to produce power some of the day, until a cloud passes over is an unbelievable waste of money.
Decommissioning costs are not a problem so long as they are built into a nuclear plants financial design. Wind farms have decommissioning costs build into them so you don't end up like western California where there are some 5000 abandoned wind turbines.
All the wind farms I have been to have a decommissioning escrow.
Decommissioning costs for wind turbines may not even be an issue so long as the land owner agrees to renew the lease. GE wind turbines may be able to be economically repaired indefinitely and the less durable mitsus may be gutted and have new equipment installed on top of the monopole.
