According to wikipedia, the geothermal energy flow is 45 TW, or 45 * 10^12 watts
The sun put out 174 PW (174 * 10^15 Watts), of which 89 PW gets absorded.
So, on average, the sun provides 2000 times more energy to the Earth then comes from geothermal heat.

No geothermal heat is free
The system however can be quite costly to install. Depending how long you live in your home it should pay for itself in several years do to lower heating bills (read almost none except for electiricty to operate fans in the system)

Yes it’s expensive to install, but will pay for it’s self in the long run

YES, The ground loop is generally the most expensive component

its a little cheaper to operate than a air to air heat pump with a 90+ gas furnace back up
geothermal heat pumps use about a 1/4 mile of plastic tubing buried 8′ deep in the ground. the tube has to be n the dirt, no sand or turkey grit around it, and there for had a tendency to get punctured. ok now how do you find a 1 gallon a day leak in something 8′ in the ground?…….that’s why i don’t recommend geothermal units

To run? No, it’s free energy. The expensive part is tapping into it. It requires a lot of dangerous, labor-intensive work to do it right.

It is expensive to install, NOT expensive to run

Comment on Are Geothermal Heating Systems Cheaper Than Forced Air Furnaces? by thenosek

The idea behind geothermal is that it uses ground heat is already about 40 F. So, in the summer, it helps the AC cool the house, and in the winter, your heat pump doesn’t have to work so hard to “top up” the temperature in the house. It sounds like your heat distribution system/heat pump is electric powered. If you switch the heat pump unit to an oil, propane or natural gas unit, you could save some money. Your hydro bill also includes what you’re using for lighting, cooking (unless you have a gas stove), refrigerator, etc. If you have older appliances that are not very energy efficient, you will be using a lot of electricity too.

They are considered cheaper to run, that seems like a very high bill. There may be some issue going on.
