The Bulletin magazine I received today had a very good article called "Wasted Energy" by Tim Flannery (page 42). If we replaced our electric hot water services with solar HWS the base load at night would be much smaller he said. He could have added that if we got rid of all the poorly designed outdoor lights it would be even smaller.
I think the best arguments against light pollution are road safety, wasted money and global warming. It is dangerous to have lights shining in your eyes when you are driving, especially on wet nights.
