Depends on the exact AC, but they usually (IIRC) have COF of about 3. So if the AC is moving 3000 W of heat, it will add about 1000 W of heat from the compressor/fan etc.
But compared to the amount of energy needed to heat the atmosphere any appreciable amount, completely trivial.
- Spivak 4y agoRight but where the source of that 1000W came from is what matters. Assume your building has solar panels and you disconnect yourself from the grid. You turn on your AC to move the 3000W of heat the sun is blasting you with and draw 1000W from your panels to do it. You don't count the 3000W because that energy was already there, we just moved it, but that's also true of the 1000W! So in a hypothetical solarpunk future of if your area is all solar during the day there's no guilt to using the AC.

- bumby 4y ago>that energy was already there, we just moved it, but that's also true of the 1000W! Isn't this also the case for any type of energy (possible exception of nuclear)? Fossil fuel energy is "already there", just bound up in chemical bonds. The analogy is doubly true when comparing it to stored solar energy in batteries. The more important feature is the systemic effects of the energy conversion and transport.
