yes, but the average town has about ten times as much street lighting that
is on ALL NIGHT as the homeowners bulbs contribute.

Street lighting could be much better designed. They should be made to point
downwards, both to save energy and to make the sky darker. Remember, though,
that those sodium lights are much more efficient that even fluorescent
lighting (they give out twice the light) and there is probably less than one
street light for every house, even given all the non-residential roads.
