Wind power = tons of concrete

According to the June 17 Dodge City Daily Globe, reporting on the "inauguration" of the Spearville Wind Energy Facility in Kansas (which is under construction),
It took 1,822 truckloads of concrete to build the 67 foundations for the wind towers, and each foundation required 272 cubic yards of concrete. The height of each tower will be 262 feet, compared to the tallest building in Kansas, the Epic Center in Wichita, which is 325 feet.
That's 27 truckloads of concrete, at least 27 tons, for each turbine. Along with the roads and new high-voltage transmission structures that the article also mentions (to get the energy from western Kansas to where it's actually needed), that's a serious impact on the prairie ecology.

And added to the height of the tower is the sweep of the blades that extend another 126 feet, for a total height of 388 feet, lit up and moving (and making noise) night and day.
