After seven days riding into frequent headwinds as part of the 37th edition of the Register's Annual Bike Ride Across Iowa (RAGBRAI) and not seeing any wind turbines, it came as a surprise to see these turbines along I-80 east of Des Moines. All along the 442-mile southern Iowa route for RAGBRAI I had been wondering (among other things) why no wind power out here? There was plenty of corn, making ethanol a huge deal there, but it turns out that Iowa also is a major player in wind generated electricity.According to the American Wind Energy Association, Iowa actually ranks second in the nation in wind generation capacity, ahead of California, Minnesota, Washington (my home state), Oregon, New York and Colorado. (Texas is first by more than double Iowa's capacity.) Indeed, Iowa leapfrogged from 4th to 2nd in the space of just two years.
The jump in wind generation is partially attributable to a state mandate that the two investor-owned utilities, MidAmerican and Alliant Energy Interstate Power & Light, obtain a combined total of 105 MW of renewable energy. In addition, the governor in 2001 established a secondary voluntary goal of 1000 MW of wind by 2010. Clearly those goals have been exceeded.
Iowa seems ideal for wind power. Not only is there frequent wind (and seemingly constant if you're on a bicycle), but the state also is close to major load centers -- Chicago is 300 miles and St. Louis 270 miles from Des Moines. Apparently some developers are offering higher lease rates for turbine locations, giving landowners a powerful economic incentive to site turbines on their property.
But, of course, wind power isn't without its pitfalls, as this article last year describes. The Adair project had its detractors, but it appears that Iowa already is thinking big when it comes to generating power from the wind.
