Answer 1

The blades are perpendicular to the wind. The wind hits all the blades, but all of that contact causes rotation in the same direction.

Think of how a fan works, with all the blades rotating to push air forward. And then run the process backward, with the air moving the blades. Exactly the same process, just reversed.

Edit: spelling.
