    how do wind generators point to windward when they don't have tail fins?

    I mean the electricity generating wind machines. They don't have a fin to make them point into the wind.

    They have what's called a Yaw drive built into them.

    Yaw drive:
    Upwind turbines face into the wind; the yaw drive is used to keep the rotor facing into the wind as the wind direction changes. Downwind turbines don't require a yaw drive, the wind blows the rotor downwind.
