Quizplus · Accepted Answer

This is due to the principle of energy conservation. The Earth absorbs some of the energy from the Sun, which is used for various purposes such as photosynthesis and heating the planet. However, eventually all of this energy is radiated back out into space, either as visible light or infrared radiation. This means that the total amount of energy in the Earth-Sun system remains constant over time.
