That is a great point, and I do think that large scale transmission (closer to a global grid) and energy storage advancements are possible, but so far have suffered from a chick/egg problems. But even so I think there's a legit place for spot generation from whatever origin (probably methane powered turbines) in a balanced energy roadmap.

There is also demand side management, where you power a system on and of based on the availablity of energy. Cooling Houses are an example of that.
