DID YOU KNOW? South Dakota is a Renewable Energy Leader

When it comes to producing sustainable energy, South Dakota is one of the top states in America.

The Mount Rushmore State ranks second behind only Vermont as the state with the highest levels of renewable energy sources, which include wind, hydro, solar, biomass, and geothermal, as reported by the news and culture site Big Think.

Nationally, sustainable sources make up only 20 percent of the total amount of energy produced.
