The conversation here seems a bit binary. Maybe I missed a few posts. The whole solar thing is not realized until cooperatives de-grid in favor of their own local grids, along with an arbitrage sharing model. That has the potential to to manage all power needs (including electrical cars). It's a scaling issue sort of in between entirely centralized and rugged individualism.

Of course the tech for this is a real threat for utilities, so it wouldn't surprise me if they would go to any length to stop such and effort. Same could be said for any deflationary tech like micro reactors.
