The Tesla charges in 4 hours (mine for only 100K+) and there's really no comparison between CO2 emissions for electric cars vs gas ones. The biggest problem with the plug-ins is their battery life and the infrastructure issue. That said, what electric company wouldn't want more demand? I am confident that although the grid might not be built to withstand half our cars being plug-in, that kind of demand would find a solution in the market.
The hybrid, to me, is a half-assed solution. I can easily make due with one gas-powered car and one electric, but there are no mass-produced electrics out there.
