How it Works
At its core, geothermal energy harnesses the Earth's inherent heat. This heat primarily originates from the radioactive decay of particles deep within the planet and from the original heat from the Earth's fiery formation. As you go deeper underground, temperatures increase, remaining relatively constant throughout the year.
To utilize this steady temperature, geothermal systems employ ground source heat pumps. These pumps circulate a mixture of water and antifreeze through a series of buried pipes, known as a ground loop. In colder weather, the fluid absorbs heat from the Earth and, upon return, a heat exchanger transfers this energy to a building's heating system. Conversely, in warmer months, the system can reverse, extracting heat from the building and transferring it back into the ground.
This method's beauty lies in its simplicity and efficiency. By tapping into the Earth's consistent temperatures, geothermal energy offers a sustainable solution for heating and cooling needs, reducing reliance on fossil fuels and minimizing environmental impact.
