Electric companies were pushing electric cars 20 years ago as a way to
wring more use out of their investment, which supplies barely enough
electricity on a summer's day but has huge reserve capacity overnight.
As somebody asked at the electric company talk I went to then, 'What
happens if people want to plug their cars in in the daytime?' 'Uh,
er..'

Given that ethanol is barely a break-even process energetically if you
manage to capture all the waste heat etc. from the process (huge fossil
fuel investment in agriculture these days), odds are, probably not.
