I said a fifth or a tenth of the land in the US used for ethanol production. NOT a fifth or a tenth of our deserts. More like 1%.

And my point is we can install solar on land that has no other use. Like land contaminated by industrial waste, etc.

1% of all deserts is only correct if you are talking about only today's electricity use. Even moderate growth and actually solving energy, not just the electricity subset drives these percentages much higher. To get US centric again, NREL published an optimistic 2016 report suggesting that the maximum rooftop solar capability could ever meet is 40% of electricity. That's 15% of today's energy use in an electricity heavy country.

U.S. electricity usage has been flat for the past 10 years[0] despite a cumulative GDP growth of 34% over the same period. I'm not saying the same trend will continue to hold, but you are overestimating future electricity usage growth.

Ah. My misunderstanding.
