Why is using natural light during the day good for saving energy?

Answer and explanation

Correct answer: It reduces the electricity needed for artificial lighting

When daylight is sufficient, electric bulbs and other artificial lights can be switched off or used for fewer hours. This reduces the electricity consumed for lighting and lowers avoidable energy demand. Natural light does not itself make a room darker or reduce appliance efficiency; the main saving comes from replacing part of artificial lighting use with available daylight.
