What happens if we don't turn of the lights?

If we don't turn off the lights, it leads to unnecessary energy consumption, which can contribute to higher electricity bills and increased environmental impact due to greater fossil fuel use for power generation. Leaving lights on can also shorten the lifespan of the bulbs, requiring more frequent replacements. Additionally, it may contribute to light pollution, which can disrupt local ecosystems and affect human health by interfering with natural circadian rhythms.
