I was in Lost Vegas a couple years ago and noticed the wind was always blowing, and of course, the sun was out in full force every day. Also noticed no windmills anywhere, and no solar collectors. Also, in Vegas, the billion or trillion lights seemed to shine 24/7. It seemed clear that the giant dam feeding electric to them was providing energy cheap enough that few cared much about wind/sun power even though to me, it might possibly work a bit in the dessert.
Where I live, electric cost lots to produce but the damn sun never shines, and wind is only around when it storms. If I had the sun and wind of Vegas, I'd have both solar and windmills, and not one small part of me is green.
