Efficiently means with no waste of time or effort. Work efficiently, run efficiently, more efficiently than before.
It is about the ratio rather than the result, which is the distinction from effectively: doing the wrong thing efficiently is still doing the wrong thing. Engineers use it strictly, as the share of energy that reaches the useful output.
