There is just this big debate about bio fuel.

But alone the higher efficiency of an electric vehicle can save much more fuel, than would be ever possible with bio fuel.
The Renault Kangoo make a compare easy, because availbale with gasoline, diesel, natural gas and plug-in hybrid electric version.
A CCPP can produce with natural gas as well as with diesel and gasoline 58% electricity out of the energy of the fuel.
So I compared how far the vehicle goes with the ICE and with the fuel in a CCPP converted to electric power

ICE cara are compared to electric drive systems more inefficient than a 1960 gasoline guzzler compared to todays cars.
