These cost comparisons don't take into account reliability. Power is almost useless if it's not reliable. A large part of your monthly bill goes towards reliablility and transport of power, not just the power itself.
A 100% wind or solar grid would require an equal amount of backup gas or coal power in order to provide reliability which essentially doubles these cost estimates. Even now most wind and solar is considered a novelty to most grid operators because you can't take it into account for long term planning. In some cases (like Denmark or Quebec) there exists ample alternatives available for when the wind stops blowing but most jurisdictions don't have this.
Considering how smart people in Silicon Valley are the level of ignorance around renewable energy and the'why don't we all use solar panels' mindset is crazy.
