Actually the places where wind is the strongest, (New Mexico, parts of West Texas, and everything directly above that in middle America) there is significant land space and not much else. Population density is all less than 10 people per sq mile and large chunks 0 people per sq mile. The people who own the ranches there absolutely love wind because it’s an additional revenue stream and the local towns are being reinvigorated due to additional revenue from the energy companies and more jobs. We need around 25% from Wind and 3% of America where there’s really not much else not even farms works out well.

For solar, the best place in North America is the Mojave Desert which also has wide open space and no population.
