Yeah, I hear analyses like that where fossil fuel costs are jacked up, but its not real because the users don't actually pay all the imagined pollution costs.  Makes for a nice story but it falls under the heading of fantasy.  We could simply to decide to lower our standard of living through increased energy costs and go mostly renewable where hydro or alternative 24/7 source is employed along with the wind and solar.  But the solar is cheaper story just ain't gonna cut it until it really is.
