Placing those entries within a list in the Wind power in Illinois article would be a good thing to do. That's what people are doing for the smaller wind farms in many states.  You could also add additional information about each wind farm, such as the manufacturers, and when it was completed. If all the smaller wind farms in Texas, Iowa and Minnesota were added, the size of this list would already be nearly doubled. People just don't want to wade or sort through long lists. And anything longer than a couple of screen lengths is a long list.
