> the areas that are deep-red and red is where Solar is both economical and environmental positive. Orange, may be environmental positive area. The rest of it is, mis-allocation. That's greatly oversimplified. One of the best places for solar panels is remote areas of Alaska. Being off the national grid, electricity is terribly expensive, and even the low output available at high latitudes is a big positive and worth the up-front costs. Whether solar panels makes sense is a highly variable issue. Rising electric prices while solar panel costs fall makes the area where they are economical expand every year. That said, with the Pacific Northwest having so much hydro power and relatively low population/demand, it might be a while before it's a good investment up there.
