ROLLA, Mo. (AP) — A World War II-era power plant at Missouri University of Science & Technology has been shut down as the Rolla school transitions to a more energy-efficient geothermal system.
The 69-year-old power plant burned coal and wood chips in its boilers before it was permanently closed last week. The new geothermal system is expected to reduce the campus's carbon dioxide emissions by 25,000 tons a year while cutting annual energy use in half. It also means the school won't have to spend $34 million on needed repairs at the aging power plant.
The geothermal system allows energy to be stored in nearly 800 underground wells dispersed across campus.
