That's exactly what the market is doing, right now. The more wind/solar we get, the cheaper and more robust they are. And when they start costing a lot less than coal/nuclear (which is where we are now), then coal and nuclear basically collapse under their own cost - which is what is happening. The fact that gas saw a big cost cut around the same time is just accelerating the inevitable. But getting off carbon will require that wind/solar become significantly cheaper than gas as well as coal/nuclear. Which may be what happens over the next couple of decades.
