Fun fact time! Brought to you by Lester Brown's Plan B 3.0: Mobilizing to Save Civilization:

An Iowa farmer would get 300 dollars for the ethanol fuel produced by a quarter-acre of corn.

An Iowa farmer would get 300,000 dollars for a year's worth of electricity generated by wind turbines on that same quarter-acre.

300,000?!?! Maybe it's time to rethink all those cornfields...
