night falls, energy rises

A friend complained to me one day about our “cheap energy”, saying that we don’t pay anywhere near the true cost of our power. So we squander it. Every night, when the sun goes down, lights go on all around the world, but no place beams brighter than the largest cities and richest populations. Check out this view from space to see what the earth looks like at night. It makes me wonder how we would spend our energy if it was limited, if we truly saw it as a precious resource, if we were rationed to a certain amount per day. I suspect that beaming light out into space would not be our first priority.
