The land argument against solar is economically foolish. In most places, the value off land is a tiny fraction of the cost of the solar installation. We have lots and lots of land, far more than is needed to power global industrial society with solar energy, and that land is very cheap.
If the cost of land ever did become a global constraint on solar energy, it would be because the other parts of solar had become incredibly cheap. At that point, solar would already have consigned all other energy sources to oblivion.
The value produced per hectare per year from a PV field is much greater than many other current uses of land, such as raising lifestock, growing grain, or commercial forestry. If solar is deemed impractical because of land usage, so should those other uses.
