All land doesn't receive the same quality or quantity of sunlight.



That is the 3.0 insolation I chose. It’s reasonably representative of areas of northern hemisphere cities. The United States average by population is probably between 4 and 5 according to this map, but winter is lower and you have to plan for that.

Northern Europeans are going to want to have some power lines to the south. Chile might be the new aluminum refining capital of the world. Africa would be energy rich.


I sometimes wonder if some of the resistance to a solar-powered world stems from their discomfort with the implied economic shift of heavy industry to brown-skinned countries.


So choose land that is poor for food production and good for electricity production, then find a way to transport the energy (one good advantage of gas/coal/oil is transportability with current infrastructure).
