Ethanol proponents keep on claiming it will bring gas prices down.  

Meanwhile, enough electricity to take your car as far as a gallon of ethanol/gas does, still costs  only 66 cents.

With your own solar panels, after a few years payback in energy bill savings, your daily dose of electric "gas" would be free.

Energy based on fuel sources, biomass, corn, sugar cane, wood chips, whatever will always go up in price with demand.  

Energy sources based on renewable resources become essentially free once the device that collects the energy, wind machines, wave machines, solar pV/heat cogeneration; has paid for itself in costly fossil energy saved.

Ethanol in the tank, corn prices soar, people starve.  

Plugin hybrids plugged into a renewable smart grid would tend to level off energy prices at around the market price at the average payback period of this energy revolution.

In ten years maybe half the systems needed to replace the status quo energy mess, would be paying off for their owners.  Energy inflation could be defeated.

Why are farmers expected to plant less corn when demand is high and expected to grow? What is more profitable that farmers are planting instead or can they simply not afford the fertilizer?

  Many of those who built corn to ethanol plants will lose their shirts. Isn't this a good thing?

Fertilizer costs have gone up tenfold in the last three to five years.  Alas, when the system is based on petroleum derived chemicals and built to fuel the petroleum industry, someone has to lose.  That someone is very often the farmer, who now has to find a way to afford the inputs to take advantage of $6 per bushel corn.  The margins for farming haven't changed, despite the record price for corn.  

To give you an idea as to how bad the cost of fertilizer has been for farmers, until recently most livestock producers have looked at manure as a "problem" they had to dispose of.  Today many livestock farmers are considering expanding.  Remember, these guys have to buy that $6 corn and feed it to their animals at a net loss when they go to sell the critters.  Why would they be considering expansion in herd numbers? Because of the manure value of the animals.  There are folks that have essentially bought future manure production of large confinement operations so they can have the fertilizer to grow that $6 corn.
     

...the increase in corn feed has helped in the recent price spike and subsequent consumption reduction in meat, specifically industrial cattle meat.
