What is the CO2 emission of a geothermal heat pump with solar power?

There isn't any CO2 emission when operating anything by solar panels.  UNLESS you consider the carbon footprint of the manufacturing of the solar panels, which is what makes solar panels not really as much of the solution as you may think.

All that the geothermal heat pump is, is a clever arrangement of the air conditioning, and it makes no emissions of anything (other than what ever was used to make its electricity source).

CO2 emission comes from combustion or respiration.  There is no combustion or respiration in a solar panel or a geothermal heat pump.


Also, don't be afraid of CO2 emission.  All it will make humans do is breath more, and it is not poison in any way.  Plant life does a damn good job of regulating the level of CO2.

CO2 is not as bad of a "greenhouse gas" as it has been made out to be.  Water vapor is perhaps more of a greenhouse gas than CO2 is, but people like to blame CO2 because it has a more poison-sounding name than water does.

Assuming you do not count the CO2 emissions that are emitted during the design, fabrication, transport and installation of the system then the CO2 emissions will be zero since there is no carbon being oxidized in the actual operation of the the system you describe.

Solar panels do not emit CO2 so you are going to be safe there.

The production of solar panels is becoming more CO2 friendly by the day as manufacturers move to wind and their own solar sources.  

I only wonder how many solar panels you will need to power that pump.  At the very least, you will need a large battery bank to power the pump during the night or during extended cloudy periods.  I predict that at least 10 x 50 Watt solar panels will be needed.  At a cost of $200 a piece, your project may get quite expensive.

Good luck and go green friend!
