"Energy Policy, International Journal of vehicle Design, Foreign Affairs, Harvard Business Review, Population and Development Review, Contemporary Economic Policy all look as though they have peer review"
All of Lovin's articles are Policy Papers, not scientific or technical papers. All his publications are geared towards politics. He does not now and has never written any technical papers (that I'm aware of) which is why his assertions about "Don't worry, it's reasonable to build this super-grid" are not reasurring. There is no reason to believe he has any detailed knowledge of how the grid works beyond a laymans idea of "it distributes energy". Hand-wavium is not serious research. He did not present a serious model of how it would work. Even basic questions about actual peak/average/minimum power generation using readily available data goes unanalyzed. Power distribution? What's that?
It's not that properly disributing renewable power can't work or is a bad idea but how difficult it would be to achieve near 100% effectiveness is a hard question he's not seriously trying to answer. A little storage and little backup power goes a loooong way to making the design a lot easier. His desire to upfront declare such things unnaceptable smacks of fanatacism not practical problem solving.
