Good post, thanks for mentioning it.
There's some interesting discussion about PHEVs there. I remember the discussions about PHEVs being a gateway drug, but I don't remember who was first, if anyone. Lately I've been trying to mull over PHEVs and what role they serve in the here and now. If we make another 2 or 3 generations of PHEVs before we finally substitute in all BEVs, how much more carbon is that (just to make the cars, not to mention burning the fuel)? If it's really just a bridge technology then how far do we use it? I suppose technically there's some possibility that a zero carbon drop-in replacement liquid fuel for combustion engines finally could be made available, or that some of the engines could be manufactured to meet the situation partway, and that could change the questions around PHEVs and whether they can play a role in a post-carbon effort, but does anyone see any real movement toward this?
Well, so much of the BEV deployment pace seems supply-constrained (for the good BEVs that is, the deployment of the less-good BEVs is probably demand constrained, as it shouldbe), even despite the moderate price of gasoline. The supply of the good BEVs appears in part to be constrained by battery supply, and so maybe that all adds up to PHEVs, with their lower kWh requirements, playing a role for awhile longer.
You quoted James Greenberger.I liked this part:
"....We will sell EVs and PHEVs to folks who bought the Prius, no question. But that is not an economically sustainable market, and it's not a politically sustainable market, because if we find ourselves in five years with a PHEV and EV market that is entirely dependent on wealthy consumers and government subsidies, the government subsidies will go away...."
