What affect does the regular use of A/C contribute to global warming?

11. I live in a desert climate. Not too long ago I installed solar panels and batteries.

Throughout the spring, summer and early fall I typically cover 99 percent of my power needs for the whole house. The 1% of power I have to buy happens sometimes when the air conditioner (a 10 year old heat pump) first starts. The exception during this period is the rare cloudy days which primarily occur during summer monsoons. Though it is rare (and welcome) to have full days of rain, it is rare even during monsoon season.

During winter I cover about half our energy consumption. Shorter days of sun and the heater draws much more energy to start up and run than the air conditioning. I’m adding some extra panels and an additional battery, so that should help but likely won’t cover all our needs.

The downside is this solution is very expensive. If I remember correctly when I bought the first round of equipment 2 years ago the tax credit for federal and state were somewhere around 23 percent. This certainly helped, but didn’t make it widely affordable.
