Edit: Sorry I made a stupid mistake. Should be 30kWh/day! That tracks much better with your own figure. Ignore the blow.

You're right, most use less because they don't charge a car. The average seems to be about double that though at ~74 kWh/day: https://www.eia.gov/tools/faqs/faq.php?id=97&t=3
Taking that average it would take around 2 weeks to reach my yearly consumption. Should be noted that's for something like 2.7 people, mine is a two person household.
