We have colder weather where I live, but I see I used 550 kwh per month (at most). Even if my house is half your size, 70 kwh seems like a lot for a daily base

We have colder weather where I live, but I see I used 550 kwh per month (at most). Even if my house is half your size, 70 kwh seems like a lot for a daily baseline. I have a similar situation (kids at home studying, me working at home). Does the the car that drives up your electricity usage that much?
