Geothermal Energy vs Ground Source Heat Pumps

There's a discussion in the geothermal circles about whether or not ground source heat pump can be considered geothermal energy. While it seems to be an argument of terminology (both use heat drawn from the earth), there are distinct differences:

* Geothermal systems pull heat directly from a natural source, such as geysers, hot springs and volcanic hot spots. Ground Source Heat Pumps (GSHP) basically run like a hybrid automobile; it still requires energy from the grid to operate, but uses that energy more efficiently.

* Geothermal systems use the heat pulled from the earth as a source to generate energy. GSHP are not a method to generate energy, but rather a way to use energy more efficiently.

* Geothermal systems are for more larger scale projects, whereas GSHP are used in residences and/or commercial buildings. They are a clean, durable alternative for those who don't have strong enough wind or solar sources to make those alternative energy options cost-effective. Families who live in urban areas may be ideal candidates for a GSHP.

* Geothermal systems depend on specific geological conditions in order to operate; GSHP can be installed almost anywhere.

While both systems utilize the heat from the earth, there are key differences. Geothermal energy attempts to solve the wide-scale energy problems the world faces, while GSHP are designed to provide a heating and cooling alternative for single family residences and business.

It's not hard to see who GSHP are gaining more popularity. They're clean, reliable, durable and carry a savings of 66% or more on heating and cooling bills. For those living in urban areas, or in an area lacking strong enough wind or solar sources, a GSHP may be the perfect solution
