I learned from them that a program being sold to the residents of Minnesota as an "environmentally friendly" enterprise actually appears to conceal a major rip-off of the public, where the purchase of land for wind mills is being use as a front to conceal taking control of mineral and water rights. The scam is so bad that the utility monitoring the production of energy has been derelict.
