Could Pure Electrics Emit More Than Hybrids?
11/15/2012

A battery electric vehicle (shown as 'BEV240') could be responsible for more social damage in the form of emissions than a plug-in hybrid, largely as a result of battery size.   (Source: Carnegie Mellon University)

I doubt this will change anything in the short term, Cabe. There's no window right now for making changes to policy. What it will mean in the future is anyone's guess. Regarding the Prius: Toyota has a plug-in called the Prius PHV and it has a relatively small, 4.4-kWh battery.

Agreed, Rob. I think the key comment is, "in a world where all our electicity is coming from cleaner sources, BEVs could be the best."

It is good to hear that full EVs are bad for the environment, to some degree. I assumed the battery fabrication was fairly high prices already. As I have been hoping for the day of owning a complete EV and avoiding the pump, now I see I will need a transitional vehicle until battery tech makes the footprint smaller. Plug in Prius on the way...

However, do you think this will inhibit development on EVs in the future?

Hybrids beating EVs

This makes sense, Chuck. Unlike the EV, the hybrid charges itself instead of taking electricity off the grid. Given that so many grids are generating electricity from coal, I can see where a hybrid would produce less carbon than an EV.
