The Fowler Ridge Wind Farm in Benton Co., Indiana, is Indiana's only wind farm.
There are over 220 of these in place, more being built now. When finished there
will be over 400 turbines. It will be the largest single farm in the U.S. and one
of the largest in the world.

The wind turbines are 240+ ft tall, and the fiberglass
blades are 60 feet long. They are so large that the crane
that assembles them has to be assembled by another crane.
Pretty cool sound when you stand under them!
