Meaning earth-based solar? Because I thought that in principle
space-based solar power could be increased to demand for millennia and
still remain an infinitesimal fraction of the total solar energetic
output... :-///

For earth-based solar, on the contrary, I wonder how many square
meters would we be talking of in a 50 years-time, taking also into
account the energy necessary for manufacturing, deployment,
maintenance and safe disposal of the solar units.
