How a Pioneering University Hopes to Cut its Carbon Footprint by Half. By Lea Radick, ClimateWire, May 29, 2009. "For many people, geothermal energy conjures up images of steaming geysers or bubbling hot water gushing up from superheated rocks deep within the Earth. The western United States is rich in this form of energy, but in the East, these heat-producing layers are too deep to be retrieved without expensive exploration technology. But geothermal also applies to the use of heat pumps that can create energy from the temperature difference between the surface of the Earth and the relatively stable subsurface temperature of approximately 50 degrees Fahrenheit at depths of about 10 to 300 feet. Which is why Ball State University in Muncie, Ind., is installing the largest geothermal heat pump system in the country. The university estimates that the project, which broke ground on May 9, will save the school $2 million in energy costs a year while cutting its carbon dioxide emissions by a dramatic 50%."
