Report from Des Moines: More Reasons Why Middle America Loves Wind Energy

Those towers mean pollution-free jobs, better crops, and more $.

WHO-TV, Des Moines:

At Iowa State University the new Wind Energy Student Organization started off its very first presentation with adviser Dr. Gene Takle.

Takle has been researching how turbines affect fields and found there is measurable influences on climate and wind turbulence, “One of the effects of turbines is they stir the air, so the crop, the corn canopy itself is drawing down the carbon dioxide level in that part of the atmosphere so within the crop it’s getting lower and lower, so the extra turbulence brings down this higher CO2 air from above and promoting more photosynthesis within the crop during the daytime period. So it’s a good thing and it looks like the turbines from our measurements are actually having a beneficial effect.”

Takle says other benefits of turbines are increase nighttime temperatures, decreased daytime temperatures, and enhanced evaporation. However, a negative includes increased respiration, but he maintains the positive effects outweigh negatives.

And farmers like to be involved with wind energy on their land according to Takle, “Wind turbines represent an alternative income stream for farmers. Farmers are in a very volatile economy, there’s up years, there’s down years. The turbines provide the same lease amount every year. So it provides some stable income, which is often valued by farmers. They don’t take very much land out of production and from what we’ve shown, they don’t have any negative impact on their farming operation. Possibly even a positive impact.”

According to the Office of Energy Efficiency and Renewable Energy, by 2030, lease payments will generate well over $600 million for landowners in rural areas in the U.S.

    OK. I am a big proponent of wind power. BUT are Dr. Takle’s assertions regarding the effect of wind turbines on CO2 distribution in the cornfield air column and production documented in a peer reviewed study? I always get nervous about assertions like that. Show me the analysis.
