I Find it interesting that TimG thinks trying to reduce the impact of CO2 caused global warming is a waste of time and has blind faith in our ability to develop the technologies required to mitigate its consequences, which he feels will be more cost effective. On the other hand, he believes developing viable electric vehicles is beyond our capabilities.
I think plug in hybrids are an interim measure and it must be remembered that to take advantage of the efficiencies they offer, they must be plugged into the grid as well.
