We didn't use any AC in September so I'm going to cover the entire 2016 cooling season in this report.
But first, it's fun to see how far the sun has moved in just one month since the equinox. The picture on the left shows the sun setting directly to the west on September 21st while the picture on the right shows how far south the sun has moved since then.

September Report
In September we used 672 kWh (just slightly higher than June). The TED energy monitor recorded 688 kWh so there was only a 16 kWh difference this month.
September racked up 179 Cooling Degree Days (CDD) which was less than June, July or August but was still almost twice the historical average of 93 CDD.

Summer Summary
This has been the third hottest summer in Georgia in the past 130+ years. However, temperatures here in the mountains have been pretty comfortable overall. The warmest day here was 91 on July 3rd. Since nighttime temperatures have generally been in the upper 60's to low 70's it's been fairly easy to keep the house comfortable without using AC.
Humidity is a bigger problem, and we did run the AC a few times mainly to keep the lower level dry.
The summer months give us a good indication of our average non-HVAC energy use. From May through the end of September we have used an average of 781 kWh per month.
The two largest items are the refrigerator (about 17%) and the hot water heater (about 14%). Past data shows that the water heater will double in the winter because the water entering the house is colder.
At the end of the year, I'll do a breakdown that shows the percentage ofl energy used for each major category.
