I think areas have a set wind speed that may or may not change and is impossible to detect without hooking it up to a windmill... meaning your zone isn't windy enough and you better get working on some water wheels =P

Wind speed is enough to make 40 power on every other windmill I have. And water wheels would do me no good. I got nothing to power them with.

It could be that you have a heavier load on it (in terms of things you are trying to drive), than you are actually providing in power. This will cause nothing to move.

Nope. Had three windmills, trying to power a device that needed 38 power or so. None of them was producing any power at all.
