This deserves a close look. The paper uses the amount of energy needed to power our personal transportation needs if it is served by a fleet of electric vehicles. Both battery storage and fuel cells (hydrogen storage) are evaluated. Using this as a basis it is fairly easy to figure out the totals for other purposes.
This graphic shows what it would look like if we grouped all the land use into one space. It is helpful to think how things like roads, building etc would appear if they too were all clumped into one spot.

The bottom line is that with both solar and wind, land use is not a problem.
