You can start your own dark sky efforts around your house. Ya know those "coach lights" around your house? They waste energy, because if you can see the glare of the bulb, you are sending light out, not down where you want it. It doesn't even make your property safer, since the glare actually makes it harder to see what's going on in the shadows. Think driving at night when the jerk coming the other way has the brights on.

You can get dark sky fixtures at Lowe's and Home Depot. A full cutoff fixture not only is more efficient, but it is also better in terms of doing what you want the light to do and improving safety as well. You will also make your own night sky more accessible as well.
