this is my point, too
renewables, especially solar, just have gotten very competitive to a point they will gain ground even if not subsidized
and I believe we will see (and in some niches have already seen) this happening for electric cars, too. They are plain simple just better technology which for now is still in the earlier stages.
How much relevance wind will have we have to see, it's less advantages then solar and less easy to deploy. It's pretty good in some very windy northern (i.e. also less solar efficient) places and often iff it's extremely windy it's not extremely sunny and if extremely sunny it's often not extremely windy. This makes them complement each other quite nicely. So I still see a future for it even outside of the more northern regions.
