But you are forgetting the huge amount of subsidized R&D (via universities) and subsidized investment costs that has already been spent. Without that, it is very hard to believe that the wind power industry would have bootstrapped itself.

The same can of course be said for the nuclear industry. Without massive R&D spending and cheap capital costs, nuclear energy would never have been viable. Today, wind and solar is beating both nuclear and coal, which is great. But perhaps The Market shouldn't get all the credit.
