There is some truth in that. But of course we can collect solar and wind power on crop- and pastureland while still using it for those things. I doubt we will be returning much of either to nature, even though about 1/3 of the US maize crop now goes into vehicle fuel, which demand ought to start to fall off eventually. In principle that land could be returned to nature, but I doubt it will be.
