Re: It may hard for you to believe but the fuel efficiencies of a large generating plant, complete with transmission losses, are far more efficient than a gasoline engine. I don't think that's the case - are you sure? Once you've considered generation costs, transmission costs, storage costs, and the additional conversion stage with its losses, fossil fuel plug in vehicles aren't as attractive. If you want to include solar and nuclear generated electricity, it may be that the most effective delivery of that energy would still be to use it to produce ethanol or synthesize gasoline. Bulk storage and delivery of energy of energy as ethanol or gasoline is so simple relative to electricity.... And it's not enough to consider existing mean vehicle energy use values - the packaging and performance characteristics of existing electric cars are similar to the VW diesel golf from some years ago, that got up to 50mpg. Newer hybid designs (supporting regenerative braking) are projected to get 69MPG, which would equate to about triple the induced efficiency of "cars" as a general energy consumption class.
