Geothermal energy is generated by the heat coming from deep inside the earth’s magma. Geothermal systems are designed to move the heat generated by the earth into the house in winter and to release the heat back into the soil in the summer. The process of generating geothermal energy occurs when water seeps deep into the ground where it forms underground pools and even underground rivers and then comes into contact with molten rock. When the water comes into contact with the molten rock or magma, steam is created that can be used for geothermal heating and cooling systems.

Heat pumps are another way of harnessing the power of geothermal energy. A geothermal heat pump is an exchange unit that depends on the external, soil temperature just below the surface of the earth. In this system, underground pipes serve to provide heat in the winter and cooling in the summer. In essence, the same heat exchange process is used by our current, electronically-run refrigerators and air conditioners. Examples of the use of geothermal energy can be found in many of the appliances we already own.

Today, geothermal power provides thousands of homes and buildings across the country cooling and heating power using geothermal heat pumps. During the summer months, geothermal heat pumps transfer heat from the interior of a building into the earth, cooling down the space inside the building. Alternately, when the temperature drops in winter, the heat pumps use the energy within the earth to heat your home or office. Using geothermal energy will save you the expense of paying for electricity, propane or fuel oil to heat your home.

Geothermal power is not available in all areas, but in many areas this energy source is a much more efficient way to heat and cool your home or office building. It is far less costly than using heating or cooling units that depend on fossil fuels. Essentially, geothermal energy takes advantage of the consistent temperature a few meters below the surface of the earth. You can extract this heat in the winter to heat your home, or drain the excess heat back into the earth in the summertime to cool off your office building or residence.

As we begin to see the devastation caused by the incessant burning of fossil fuels on our planet, incorporating geothermal energy into our heating and cooling systems is a wise investment. By using geothermal energy to maintain our buildings at a comfortable temperature, we will begin to eliminate the huge impact of fossil fuel consumption on our planet in an economically-sustainable way.
