They have coal fired and nuclear power plants all up and down the Tennessee River valley that extends into Alabama and Kentucky.They also have extensive research facilities in Alabama to study the problem. They could easily set up stills to run off the spent steam used to turn the turbines. The cost of the heat and steam would be free. There are beacoup acres of farmland to raise corn or other fermentable crop.
Sounds reasonable to me, but whatever the sources whether they be ethanol, biodiesel, nuclear or whatever; we've been down this road since the seventies and it's time to FINALLY get off the dime and start resolving the problem!
If we had done in the seventies what Brazil started doing;
we would be totally self-sufficient today as Brazil is.
Personally, I quit commuting in 1979, started working out of my house and never looked back.

A little research would show that the temperature of the 'spent steam' in not adequate to run a still.
