Lower clock rates mean lower energy usage per operation (due to quadratic resistance effects). Even transportation of physical goods sees the same dilemma. However, we know that in real life we have to balance environmental degradation (i.e. everything decaying), expansion potential (it may be better to use more energy per op now as an investment) with the process velocity to achieve our goals.
You can also consider the 2nd law of thermodynamics (implying finite lifetimes of anything): even the Sun itself will one day go extinct… although of course this is more of a science fiction discussion.
