Windmill Choreography

A brief history of windmills

Images of windmills through history

A list of popular/famous windmills includes two in Pella Iowa.

I’ve been traveling a lot over the past few months. It seems nearly everywhere I go where there is flat land or vast rolling hills, there are modern windmills standing like sentinels along highways and byways. Some are near, some far, often in line, dotting the countryside and farmlands. Some are still, their blades turned away from the wind. Others’ blades rotate with the prevailing winds and breezes. I remember counting water-pumping windmills on farms as our family was sardined into the family station wagon between Kansas and Iowa. Just one of the many road games we played to keep occupied.

Heading east on I-80 through Iowa last week I passed a wind farm (a loose term) spread over miles of farmland adjacent to the highway. For some reason I took note of how different the individual towers reacted to the wind that powers them. Though it would seem they should all be facing the same direction and rotate at nearly the same speed, that was not the case. Not including those whose blades turned away from the wind, others, even in line, rotated at different speeds, some with blades facing different directions. Man-made machines dancing with the wind. Inanimate objects led by one of nature’s most powerful forces, creating a unique choreography between man and our mother earth. Cruising the county roads on my recumbent cycle years ago, I was able to get close to some of these towering generators, close enough to hear the whoosh of their blades cutting through the air. Another unique aspect of the dance between technology and nature.

Having decided on this week’s topic over a week ago, I set out on an off-paved-road adventure on Tuesday. I knew approximately where the aforementioned wind farm is, and retraced my path, this time using county roads rather than interstate. Eventually, I came upon one of the giants near Marengo.

Onto the rural gravel road I ventured, heading west into farmland dotted with towering fans watching over crops and farmsteads.

A gorgeous Iowa summer day only enhanced the experience of chasing the perfect view of these 300 foot stalks, large enough at the base to hold a family vehicle, tall enough to carry three, 200 foot blades each.

Can you see them all? And what’s up with these four in the foreground, facing different directions and turning at different speeds?

Looking east. The prevailing breeze from the west. I had to wait for the road dust to clear before taking this pic.

Speaking of choreography, look at those two in the distance. They were probably about a quarter of a mile apart and spinning at different rates and sequence.

It is difficult to capture the majesty of these giant turbines, stabbing the summer sky while watching over the August corn, disturbing neither man nor animal.

I was unable to get too close without trespassing. I hoped to hear the whoosh of the blades. Try it. Turn up the volume while watching. Hear the birds?

What man made to ease our reliance on fossil fuels, wind choreographs a dance and a song. I may be treading on my political safety net, but doesn’t it seem logical to gather energy from less toxic natural sources like wind and sun? Iowa is among the top three wind produced energy states in the nation. Though I don’t have much to cheer about Iowa these days, I am proud of this achievement. I am aware, however, that there are still challenges recycling blades, etc. Hopefully, our free-market economy will find a way to make it financially viable to do so.

Existing amongst these man-made giants is not quite like the swaying of branches or the rustling of leaves, but seeing them from the highways and byways is a treat. I am happy to share this positive experience with you, contrasting emotional challenges I typically convey. I hope you, too, enjoy. Maybe you can take a road trip of your own to visit some rural areas near you and experience some positive coexistence between man and nature, like – windmill choreography.

P. S. I had the opportunity to drive past the decommissioned Duane Arnold Nuclear Power Plant near Palo IA the other day. I hoped to snap a pic of the cooling towers to contrast with the windmills. Unfortunately, those have been demolished. Only an exhaust chimney remains. I think the property is being transformed into a solar energy farm. And yet, there were signs along the county road with the words “Commercial Wind Farm” and a 🚫over the top of them. Okay. I get no pipelines, nukes, coal, even natural gas. But what’s wrong with wind and solar?
