Wind generators still are getting more efficient - partly because they are still improving, especially in the generator part, but mostly because they are becoming larger and the wind gets stronger the higher you are above ground. And yes, we will need to build more of them, many more. We don't need 10x of the required capacity, but more than the required capacity and then put the excess energy into storage. And of course it always will be a mix of wind and solar.
