There are plans for all 50 states [1]. The science still exists, despite being behind a paywall. You'll find much more description of this paper on Ars Technica [2], but I think that the paper has addressed your concerns. Also, Stanford building a natural gas plant has nothing to do with research which is a blueprint for action over the next 40 years, so it's a distraction from your main points.
