As the price of oil goes up, the price of ethonol needs to go up and a roughly proportional rate. It takes a lot of energy to make ethonol, starting a tractor fuel, fertilzer and on and on. If anyone is waiting on ethonol as a cheap alternative to gasoline they will be waiting a long time indeed.

They made ethanol long before the Bible was written.

You can even make it from fermented algae from the ocean.
