This video is about how we don’t just need energy to power our lives, we need *low entropy* energy! This is also known as “free energy”, and one way of thinking about entropy is as the lack of free energy. The sun provides us with useful, low entropy, energy in the form of photons of visible light, which are then absorbed and converted into plants, sugar, complex molecules, etc, before being radiated back into space as heat, which has much higher entropy.
