There really is no obvious rhyme or reason to my utility consumption when neither the heat nor the air conditioning is in use.
Yesterday was a mild day, overcast, a bit breezy, temperature probably in the upper 70s. Last night's low probably was around 60° or so.
Nevertheless, my electricity consumption went up.
(It's been overcast this morning. It was raining just a few minutes ago. Consequently, I have had to adjust my position for photography because the automatic flash tends to wash out readings.)
This morning's reading is 8553. Yesterday's reading was around 8544. That's roughly 9 kWh.
But Friday's reading was 8537 — 7 kWh consumed from Friday to Saturday. And Thursday's reading was 8532 — 5 kWh consumed between Thursday and Friday.
