I fly around a big portion of the globe...more often than not at night. What really has made me think is looking down at city after city after city burning MILLIONS, nah BILLIONS, of bulbs while the bulk of the populations is asleep.
India as just one example is almost a continuous sea of electric lights from coast to coast.
How much better off would the world be, on any number of levels, if cities went to minimum lighting between 2200 and dawn LT?
It is just BIZARRE how much energy is wasted globally on electricity....the vaste bulk of which is produced by coal fired generators.
