How is geothermal energy being used?
Currently, geothermal energy is gaining popularity as an energy source to cool and heat homes throughout the US. There are many different techniques and methods, but it is basically utilizing the technology of heat pumps drilled into the ground to tap into the more stable temperatures. In winter heat from the earth is transferred to building, while in summer it can transfer heat from the home into the ground (acting much like a refrigerator).
