That's only the case because it was the cheapest option available for a while. Oil execs noticed the trend and got cold feet, now a lot of governments are cutting back subsidies for renewables and actively hinder new projects being build. Here in germany we have investors abandoning half build solar parks cause they aren't profitable anymore. At the same time we allow oil companies to bid for gigantic offshore projects just so they can say that they have no interest in actually building it after they won.

With the ozon hole you could see the world working together to fix it despite it beeing somewhat less profitable. With renewables you can see governments actively working against the movement despite it being the best in terms of environment and profits combined.
