Wind just doesn't stop blowing across the world all at once. When one place is in the doldrums, another is likely windy. With a sufficiently connected grid, a large deployment of wind turbines can smooth out production in ways smaller, regionally focused deployments cannot. I posit that a global distribution of wind power is _more_ available than a regional one, not less, as your comment seems to imply.
