About the hybrids, I personally think the same than Carlos Tavares, president of PSA, who said to the French government that hybrids are only a temporary solution because two motors systems is one too many for cost reasons, when batteries will become cheaper.
A BEV that meets essentially all of your needs in terms of range has to have a battery ten times the size (give or take) of a PHEV that runs on electricity for 80-90% of your travel.
No matter how good batteries get, ten times will always be ten times - the expense, the environmental impact, the weight, the charging time.
Think about ICE cars - at least in the US, people want tons of power that they rarely use - you can get a car with 300 hp, but most of the time you're not using 30 hp.
It is never going to be optimal to have a battery enough for all your travel any more than an ICE for the maximum performance you might want.
The rational transportation device of the future has a small battery, a small ICE, and a big electric motor.
But the point I am going to keep making until I hear a good counterargument is that this is independent of foreseeable technology advances in batteries. It doesn't matter how you get your kWh or what it costs, it's not good for anyone or anything to utilize ten times the amount.
And assuming that BEVs are not the most environmental vehicles on the market doesn't mean that a gas guzzler truck is better.
My gut reaction (or prejudice, but I like mine better than yours) is that currently hybrids, plug-in or not, have the lowest total CO2 emissions. But we should all remember how often people claimed that cars like the Prius were worse for the environment and surely in this era of them being taxicabs, you have to retreat on that.
The simplest rule of thumb is, in my opinion, whether something is cheaper, unsubsidized. There may be externalities, but if you are unbiased, you cannot use special pleading to say thing A has externalities as if thing B doesn't (unless or until you have specific justification).
I'm also really sick of hearing that the Leaf or whatever is coal powered. I live in one of the largest states in the US, and virtually none of the electricity comes from coal. And everywhere, coal power is in a major decline due to market forces.
Just be honest.
