I don't know if it will ever shrink under 10%, and even if we could shrink it we wouldn't want to. Hear me out: Now that lighting is cheaper, we can have more of it at night. By properly lighting parking lots, community streets, and parks we can reduce crime while increasing economic and leisure opportunities in cities. I don't think the 10% figure is too much. Lighting frees up spare time for leisure, study, or even business (safely). If anything, lighting is the ultimate service because it gives people more time to do what we must.
