How is geothermal energy used to power buildings?
A much more conventional way to tap geothermal energy is by using geothermal heat pumps to provide heat and cooling to buildings. Also called ground-source heat pumps, they take advantage of the constant year-round temperature of about 50F that is just a few feet below the ground鈥檚 surface.
How do geothermal heat pumps work?
In thousands of homes and buildings across the United States, geothermal heat pumps also use the steady temperatures just underground to heat and cool buildings, cleanly and inexpensively. Below Earth’s crust, there is a layer of hot and molten rock, called magma.
