They already are less expensive in areas that have the specific resource. For example, in windy parts of the world, wind is the least expensive. In sunny parts, solar is the least expensive. This is without subsidies.
With specific subsidies, the area where they are less expensive is even larger.
Of course, fossil fuels receive considerable direct and indirect subsidies, further complicating answering the question "what's least cost?"
