How is it possible that every energy transformation increases the entropy of the Universe, even though they don’t all increase the entropy of the system in which they occur?

Question

How is it possible that every energy transformation increases the entropy of the Universe, even though they don’t all increase the entropy of the system in which they occur?

Answer 1

Good question! Remember the change in entropy deals with the system and the environment. So when the system’s entropy decreases, the environment’s entropy increases, and vice versa. The amount of increase is greater than the decrease.
