Street lights are essential in today’s culture. They promote human safety by illuminating the nighttime routes, which prevents accidents. Humans can also feel more secure because most of us are terrified of the dark. Indeed, street lighting has grown to be an essential component of cities all over the world. Street lights are a vital part of every contemporary society, but they are also a huge source of energy waste, carbon emissions, and light pollution. However, reducing the street lights, especially when no one is around, is definitely achievable and advantageous. Turning off the street lights completely will save energy, reduce carbon footprint, and stop light pollution.
