You wouldn't expect a clean energy revolution to be emanating from a small county in northeastern Iowa. Yet, Winneshiek County has something like 10X the solar per capita deployments compared to the rest of Iowa, has one of the first green banks in the Midwest, and has become a model for about ten other counties. We interview Andy Johnson, Director of the Winneshiek Energy District, and learn why they've been so successful and their vision for how to scale their success.
