It does not have to be 'economically practical' in the usual sense.
If the entire US defence budget for one year was diverted to solar PV it
could generate sufficient electricity for the whole of the US. Clearly this
is technologically impractal, but does illustrate a point. If it requires
hundreds of billions of dollars annually of military spending to maintain
security of oil supply the notion of what is 'economical' goes out of the
window because oil is getting a vast hidden subsidy.
