Thanks.
I guess the last paragraph says it all:

This certainly begs the question of what the point is, anyway. If everything past HEV looks like it’s coming out a wash, why should we change our habits and through all this money at PHEV and FCV production? The answer is simple, though not always apparent. When the energy burden is shifted from each individual automobile (with numbers in the millions) to a much smaller number of power plants, government regulations and new technologies will be much easier to apply. Try to imagine changing every car on the road to a HEV, and then imagine making a law saying that the grid must be 20% renewable in 10 years. It will be much easier, especially on the average citizen, to have a large change take place in a much more concerted, and less individual manner.

A couple things worth adding: Since the fuels needed to make electricity are abundant, and oil is not, moving to electric vehicles helps ensure our future stability with regard to oil resources. Since electric power can be made without fossil fuels, we need not be concerned with the pollution IF we are willing to make the move. Also, electric vehicles have far fewer moving parts and require less maintenance, resulting in even less waste.
