The energy itself is free.
Obviously the windmill is not, and from what I've seen the payback period is about 10 years for these things.
Actually the interesting thing about the energy in windmill is that these actually *remove energy from the environment*, essentially contributing to "global cooling". Of course that is undone when the energy is used (to heat a home or light a lightbulb, etc.) but they do have a net-zero effect on global warming.
