The biggest problem with moving everything from gasoline to biodiesel is our inability to make enough for every vehicles to use.
The problem is with Biodiesel production itself - it still needs oil, lots of it. At the moment, that oil is vegetable oil and the problem with using vegetable oil is that there is not enough arable land (ie. farming land) to be able to grow the vegetable stock to cater for the amount of biodiesel that is needed, as well as still allow for the farming of foodstocks that humans need to survive.
So we either use the land to grow food stock so we can live, or we use it to grow plant stock for biodiesel so we can drive - I know what I prefer
ATM there is research into using algae to produce the oil, so as to not use the arable land that is already needed for growing food - but that is still in the R&D stages and will take many years before they gain enough from their research to actually start manufacturing biodiesel on a large enough scale to be worthwhile.
Saying that, using biodiesel will still be needed in the future, because long distance travel and/or travel distance of larger heavier vehicles will always be an issue with batteries alone.
It would still be beneficial to use it as much as possible in current diesel engine vehicles too, especially those used in transport and shipping.
So while I do agree it is needed in the future, and diesel engines and biodiesel fuels will no doubt replace gasoline and current diesel vehicles, there just isn't any way possible to do that using current technology and manufacturing processes.

There will always be pollution no matter what - we just have to choose the option that has lower pollution that still caters to our needs
With gasoline, there is more pollution in production, and then more pollution using it. Plus the crude oil it is refined from is a limited resource and running out.
With lithium based batteries, there is less pollution in production, no pollution during use, and only minimal pollution during charging that can be offset using green power. Plus there is enough lithium currently located on earth to last the next 2 millennium - more then long enough IMO
So between electric vehicles using lithium based batteries and gasoline engine vehciles, the electric vehicles is easily the cleaner alternative.
