How We Use the Sun

The video explains how life on Earth utilizes the sun's entropy rather than its energy. It clarifies common misconceptions about solar energy, emphasizing that the Earth does not retain energy from the sun, as it would lead to overheating. Instead, the Earth receives low entropy energy and releases high entropy energy, primarily in the form of infrared radiation. This process involves photon dynamics, where fewer high-energy photons from the sun are converted into many low-energy photons. The interaction between the sun and the cold background sky facilitates this energy cycle, which is crucial for plant life and, subsequently, all life on Earth.
