I just ran my last year's electricity. I'm around 26 kWh/d in the DC area in an old inefficient house around 1500 ft^2. While it had a gas stove, gas water heating, and gas house heating, it did have electric window AC units. I'd be really interested in how the previous author had 6-8 kWh/d.
I used about 8 KWh/day when I lived alone in a 1550 sqft townhouse with gas heat and cooking. That ran my IT equipment, refrigerator, and blower fans for heating and exhaust. No AC usage.
Now I'm in single family home and my energy use is bonkers, but most of that is heating while I'm missing part of my roof and an entire exterior wall. It should be criminal for a town to take two years to approve permits.
