The problem with ethanol is that producers use corn when there are plenty of other sources that would not adversely effect the cost of foods!!!!!
Corn is used in almost every packaged good found in a grocery store and is a vital foodstuff for livestock. Make it less available and the price rises. Those prices are passed on to EVERY American consumer!
And, ethanol is a joke!!!
I drove a taxi powered by LPN for six years! It was a good as the highest grade gasoline, produced less than 10% of the emissions and is a hundred times more plentiful than petroleum products!!!
Yup. Anything high in cellulose will do. I know a guy who has a motorcycle that burns alcohol. He makes his fuel from day old bread and doughnuts. He also makes it from cat tails and is experimenting with lawn clippings. Engines run cooler on straight ethanol to.
The US farmer produces over 12 billion bushel of #2 yellow field corn every year. Humans eat sweet corn. Humans do not eat this field corn. It is fed to livestock. Extracting Ethanol from this corn only uses the starch of the corn. All the protein remains as Distiller Dried Grains (DDG) animal feed. Protein is what builds muscles in animals. Muscles = Meat, Steak, Hamburger, etc. Corn starch created methane gas in farm animals. This is smelly & is 15 times stronger of a greenhouse gas than (CO2) Carbon Dioxide ever was.
If you converted all the Corn grown in the USA into Ethanol it still leaves US & the World nearly all the animal feed value in the form of DDGs that we would have got from feeding corn directly to animals. We still export the DDG animal feed to China & the rest of the world the same way we did the corn. Sugar cane, switch grass & algae do not have a usable food co-product. They only create toxic waste. That means when you take away farm acreage to grow one of those, you truly decrease the worlds available food & drive up food prices. That does not happen with corn ethanol.
If you converted all the Corn grown in the USA into Ethanol it can replace 25% of the total US Gasoline demand 12% of the total US Crude Oil demand.
Mixing Ethanol into Gasoline prevents the need for refineries to add the ground water polluting MTBE into gasoline.
Ethanol production in the USA has created over 500,000 good paying jobs in the USA. Not part time minimum wage jobs.
