Bowling Green is the county seat of Wood County, Ohio, and as of the 2010 census, the population was 30,028. Part of the Toledo Metropolitan Area and a member of the Toledo Metropolitan Area Council of Governments, Bowling Green is home for Bowling Green State University. Bowling Green is within an area of land once known as the Great Black Swamp, which was drained and settled in the 19th century, and the resulting nutrient-rich soil makes for highly productive farm land. A public demand response bus service is operated by the city through B.G. Transit, Bowling Green State University offers shuttle services via its own buses with routes throughout campus and the downtown area. Bowling Green is home to Ohio's first utility-sized wind farm. In total, Bowling Green is home to four turbines that are each 257 feet tall and generate up to 7.2 megawatts of power, which is enough to supply electricity for some 3,000 residents. Located about six miles from the city, the turbines can be seen for miles and have become a local attraction. At the site of the turbines, a solar-powered kiosk provides information for visitors, including current information on wind speeds and the amount of energy being produced by the turbines. Interesting events that are held during the year include the Black Swamp Arts Festival in September and has been ranked in the top 100 shows by Sunshine Artists Magazine; the National Tractor Pulling Championships; the Wood County Fair, a week-long festival that begins shortly before or after the end of July; and the annual Winterfest.
