Becca Costello / WVXU Cincinnati officials broke ground Thursday on the largest municipally led solar array project in the country. The New Market Solar Project is being constructed on nearly 900 acres in Highland County, about 40 miles east of Cincinnati. "If every major city, county, and major company like Fifth Third — who went solar this year — did something equivalent, we would see a CO2 reduction in the state, in this country, of over 20 to 25%," said Mayor John Cranley. The city has been working on the project for about five years, partnering with several energy companies and the farmers who own the land.
