What is the difference between Geothermal HVAC and Heat pump?

Question

What is the difference between these two renewable energy air conditioning systems?

Some context to your particular situation might (or might not) be useful... if you'd like to edit that into your question, you may get a more useful response. — Highly Irregular, Nov 17 '15 at 06:40

A ground-source heat pump is not a form of geothermal energy at all.

Geothermal:

Ground-source heat pumps:

energy source is solar radiation;
source temperature is about the same as annual average air temperature;
Energy is extracted using active technology, compressing and expanding fluids to lift the temperatures to something useful.

I see. Ground-source heat pump is not exactly a form of Geothermal energy – good good good Nov 18 '15 at 07:50

So the geothermal heat pump refers to geothermal energy? – good good good Nov 18 '15 at 08:05
Can you give a specific example of a "geothermal heat pump"? – 410 gone Nov 18 '15 at 08:06
I just read an article from here(http://energy.gov/energysaver/heat-pump-systems) in paragraph 4, it says that geothermal heat pump includes ground source heat pump and water source heat pump, is that true? – good good good Nov 18 '15 at 08:16

Oh, I see. That is weird. – 410 gone Nov 18 '15 at 08:17
