Use low wattage street light bulbs. Check out what they did with the Don Valley Parkway in Toronto. They used a different kind of light bulb that produced better light at a fraction of the cost. All public lighting should be reviewed. Every second or third lamp should be unscrewed until the deficit is brought under control. There are many many places where lights are on all night for no reason. At a minimum adjust the auto-turn off of lights a half hour early and turn them on a half hour later. How many millions would that save?
