ever fly in a jetliner anywhere, dude?  I don't think those are going electric in the next hundred years.  Demand just seems to perpetually rise for airline seats ... and the fossil fuels that make flying possible.  As for the rest of transportation - we might all be driving ever more efficient cars, trucks, trains, planes and buses .. but the global consumption of oil will not go lower than today, as developing nations arise and our populations increase.  We'll just consume a lot more electricity from hydro and nuclear in future (the only two viable mass sources of clean electricity), and per capita a lot less fossil fuels .. but the aggregate will be continued global increase in fossil fuel consumption.
