Is this satire?

The US has very little desert in the Sahara or Saudi Arabia style of nothing but sand and rocks. Most desert areas in the US are covered in cactus, brush, and grasses.

One acre can produce 250 - 300 kwhrs of electricity, enough for 10 houses. 22 million acres would mean it could produce enough power for every home in the US.

Where do you think that power should be coming from to stop the cactus, brush and grasses from getting more shade?

Mostly nuclear fission and hopefully fusion in the future, but one does have to worry about heating up the earth directly with these methods in the very long term. Using solar and wind only does prevent that problem.

No. One example of many: https://www.nps.gov/jotr/learn/nature/cryptocrusts.htm
