SOUTH BEND, Ind. — The University of Notre Dame has added three underground geothermal fields in an effort to lower the campus' carbon dioxide emissions.
The South Bend Tribune reports (http://bit.ly/2v0xwej ) one of the fields is currently operating and the two others are expected to come online in 2018 and 2019. The geothermal fields are expected to reduce the school's carbon dioxide emissions by about 11,800 tons.
They come after Notre Dame announced in 2015 that it would stop burning coal entirely within five years and cut its carbon output by more than half by 2030.
The school is investing $113 million in renewable energy sources and projects.
Officials say Notre Dame has invested about $40 million in the fields and expects to recoup the cost in energy savings within 15 years.
