A modeling analysis led by ORNL gives the first detailed look at how geothermal energy can relieve the electric power system and reduce carbon emissions if widely implemented across the United States within the next few decades.

Although variable refrigerant flow heat pumps are known to have advantages, higher initial costs and difficulty in quantifying those benefits serve as deterrents to their widespread use. ORNL’s flexible research platform, however, provides a solution that enables researchers to chara...

A ground source heat pump installed at rural Cedarville High School in Arkansas through the American Recovery and Reinvestment Act has reduced energy use by 53 percent and carbon dioxide emissions by 52 percent, according to an Oak Ridge National Laboratory report. ORNL researchers X...
