The Associated Press reports workers have begun demolishing the twin smokestacks at Ball State University in Muncie, Indiana.
The smokestacks have become obsolete by the university’s $83 million installation of a closed-loop geothermal energy system, the nation’s largest project of its kind. By switching from the boiler system to geothermal, it reduces the amount of carbon dioxide Ball State releases into the atmosphere by 85,000 tons annually. It will also cut Ball State’s carbon footprint in half.
Ball State drilled about 3600 boreholes for a geothermal system and is wrapping up the five-year project. The system created 2300 direct and indirect jobs.
Water Well Journal first began reporting on the geothermal system in its November 2009 issue and reported on project updates since then.
