In principle, I would say that higher execution speed equals more
grenn-ness. Less time spent dissipating heat means less energy
consumed.


So the question actually is the same as ever: how to we make code
run fast?


- How do we squeeze more meaning into fewer/faster instructions?
- How do we make code so small that it fits in caches?
- How do we organize code execution in such a way that cache
    stalls are minimized? (Locality)
