I'm guessing that would be below peak day usage for me--i.e. two window AC units running (which isn't common)--but 14600kWh/year seems pretty close as an average based on my $100 or so monthly electrical bill. That's for a 4BR house, albeit a smallish one, that uses oil heat almost exclusively in the winter and runs fans, and only sometimes AC, in the summer.

My electric company sends out a comparison statement periodically and says I'm about average for similar-sized neighbors. (Albeit, it thinks my house is a bit smaller than it is.) So I'd say Tesla's calculator is about right for the US although it's going to vary a lot based on AC and electric heat.
