The payback period has been dropping over time and is now under a year, in some cases well under a year. This depends on many things including where it is placed, size of the tower and time of year.

Wind can compete favorably with solar on price when you have the right conditions, which are both starting to beat traditional sources of power. It is hitting the point where you would select either wind or solar for price, when ignoring the desire for stable output. One current issue for wind power is what to do with the waste. The blades erode over time and need to be replaced, but mostly consists of fiberglass. It's not a huge problem, but each advancement in technology brings a new set of problems to be dealt with. Still, I'd rather deal with fiberglass than nuclear waste.
