The development of wind power in Iowa began with the enactment in 1983 of a state law that required investor-owned utilities in the state to buy a total of 105 MW of power from wind generated electricity, one of the first renewable electricity portfolio standards.
In 2010 and in 2009, Iowa led the U.S. in the percentage of electrical power generated by wind, at 15.4 percent and 14.2 percent [REF].
