Farming's Next Frontier: Solar Energy

Indiana's solar industry has been booming. It's projected to grow to be the 4th largest in the U.S. over the next five years.

For farmers across America, planting season is well under way.

"In this in this area, I've had some mint here, you know, peppermint, seed corn, commercial corn, soybeans," said Indiana landowner Norman Welker.

But rather than seeds, a group of farmers in Northwest Indiana are putting steel piles into their ground. The reason? To harvest something other than crops from these fields.
