"Consequently, there is a risk that policy formation for climate-change mitigation will be based more on considerations of publicity and popular opinion than on evidence of effectiveness, impacts, or feasibility."
.
"In neither case is evidence from system simulation provided for how this might occur."
.
"The Mason and colleagues’ studies reinforce the notion that integration of variable renewable energy sources into existing grids can be cost-effective up to penetrations of around 20%, after which integration costs escalate rapidly"
.
"Our review of the 100%-renewable-scenario literature raises substantial concerns. The widespread assumptions of deep cuts in primary energy consumption defy historical experience, are generally inconsistent with realistic projections, and would likely raise problems for developing countries in meeting goals of poverty alleviation"

Great. So a 100% rebuildable source replacement for all energy isn't feasible on a stricly functional assessment even assuming a cornucopian availability of hardware and area to implement it on. But after all of that, There was no investigation whatsoever of the actual physical requirements of resources or the costs involved with the roll out to even try. Which is obviously a much bigger consideration when you see the scale of land use, let alone the mining refining, manufacturing, and installation of all of this 1/4 of a country sized hardware. And then the continued maintenance.
.
This is where such studies as Without The Hot Air and Roadmap To Nowhere help us see the scale of our dilemma. So that we might wake from this green trance and try to consider what we CAN do as the end of oil approaches.
