We are using four resources like Speed Breaker, Wind Mill, Solar Energy, and Piezo Plate. Energies are generated from all of them and stored in DC BAttery. Two sensors are used in which first Sensor is placed near the solar panel which detects day time or night time. When roads are free then alternate street lights turn on. Second sensor detect the presence of vehicles on the roads then all street lights are turned on.
Each street light can have its own photo voltaic panel, independent of other street lights. Alternately, a number of panels can be installed as a central power source on a separate location and supply power to a number of street lights.
