>And it doesn't matter if we have tons of electric if all of our transportation infrastructure requires oil products. Converting all of that infrastructure is going to take lots of capital and energy. I don't think biofuel represents a viable long-term solution, but butanol is practically ideal when it comes to the search for a short-term transition fuel. It runs in ordinary modern engines without modification, and vehicles from the '90s have been successfully run on 100% butanol without issue. http://en.wikipedia.org/wiki/Butanol_fuel http://en.wikipedia.org/wiki/Butanol_fuel http://nabc.cals.cornell.edu/pubs/nabc_19/NABC19_5Plenary2_Ramey.pdf http://nabc.cals.cornell.edu/pubs/nabc_19/NABC19_5Plenary2_R...
