A community college in central Illinois says a new wind turbine on campus is expected to generate about half of the electricity used by the college.

The turbine at Heartland Community College in the town of Normal is to start producing electricity by June.

It's expected to save the campus about $320,000 a year on its electricity bill. The savings will help pay off the college's share of the project's $5.2 million price tag in 15 years.

The college got $1.4 million in grants from the U.S. Department of Energy and the Illinois Clean Energy Community Foundation. The rest of the money is from bonds.

Heartland is believed to be the first college in Illinois to have a large, commercial-grade turbine.
