Light has enabled many scientific innovations and technological advancements. New light sources like solar panels, LEDs, and future technologies like Li-Fi could provide sustainable energy and internet access. However, light pollution from uncontrolled outdoor lighting is a growing problem. Solutions include using more efficient lighting, motion sensors, and government policies to reduce wasted and unnecessary light emissions.
