How many windmill rotations does it take to send a rocket to Mars?

I want to live in a pollution free world, where all creatures can breath clean air.

I also want to live in a high-end space civilization, where its possible to travel to other planets in our solar system (e.g. Mars).

I therefore need a lot of clean energy, and I'm researching the best source.

This question is related to wind energy.

Question: How many rotations from an average-size land windmill does it take to produce the energy needed to travel to Mars?

The rocket used for Mars travel would be something like SpaceX's "Big Fucking" Mars Rocket

EDIT

To simplify things a bit: The wind-mill produces the rocket fuel on site (no power lost in transmission and storage). The fuel is liquid oxygen and hydrogen.
