i think one thing the author is missing is that power is much easier and cheaper to transport than either food or water. the best places to grow food are not always near people and a lot of unused land has reasons for its state. installing solar power to create production in the desert is vastly cheaper then pumping water there, and then transporting the food back to populated areas. i can think of about 50 other inputs the author failed to include, i don't think it's as simple as comparing square footage efficiency.
