Geothermal
It has been used for several decades, though it has been referred to under many names--ground source heat pump, geothermal heat pump, geoexchange, earth source heat pump, ground coupled heat pump, earth coupled heat pump, etc.
Geothermal heating is the most reliable, usable form of renewable energy. It does not rely on the sun shining or the wind blowing. The earth holds a constant, reliable source of energy.
How do Geothermal Heat Pumps Work?
A geothermal heat pump is an appliance that can use energy from
the sun that's stored in the earth to heat your home. It also uses
the earth as a heat-sink to disperse heat from your home to the
ground in the cooling mode.
The earth is the largest solar energy collector on our planet.
Energy from the sun is collected and stored in the earth's crust.
This energy can be extracted very efficiently by using an EarthLinked
geothermal heat pump.
To do this, it employs an earth loop. An earth loop is a series of
pipes installed in the ground to circulate refrigerant between the
heat pump and the earth.
The earth loops can be installed in vertical bore holes, diagonal
bore holes, horizontal trenches, or a horizontal pit.
