Someone pointed me at an excellent interactive UK light pollution map the other day, apparently done as an overlay on Google Earth. It’s quite shocking to think that all those bright areas represent wasted fuel, wasted energy and, especially in the current economic climate, wasted money.
I am lucky in that having spent a good fifteen years living in several of the red areas of the map I now live in one that doesn’t even show up on the map, although there appears to be someone a mile or so across the valley who’s doing his level best to change that.
