Can you elaborate on your question? Do you mean: * are there scenarios where a new wind power installation would be profitable without subsidies today? * are there examples of window power installations becoming profitable without subsidies already? * are there examples of existing wind power installations demonstrating a positive ROI against subsidies that were committed? * hypothetically, how would wind power, as an abstract industry, compare against alternatives if subsidies had never been never committed? * hypothetically, would wind power installations that are now viable without direct subsidies have been possible without industry subsidies in the past? etc These all have different answers/analyses and your question is ambiguous across them. And that's probably why you're not finding the answers you want. Not because those answers are not available, but just because your question is too vague to have one conclusive answer in the first place.
