@zazzoo The article talks about land use as well. Of course, that usually means building single family houses but it also discusses using land that performs poorly as farm land (in which case, they would probably get less than 25,000 miles of ethanol).

You can do both. For example running sheep under solar panels helps both improve the soil and gives you improved wool yeild.
Crops grown under solar panels can give better yeilds as moisture in the soil doesn't dry out as much in the shade
