But that's not impressive at all; all these numbers really depend on what that electricity is being used for. Our heat and hot water are not electric. AC doesn't get used much, since we're far enough north (Massachusetts) that it's not a big deal. So that leaves lights, electronics, and the stove/microwave/vacuum...
My parents, on the other hand, are in the DC area, electric AC, heat, hot water. They're spending probably triple what you are on electricity.
Anyway, point is counting just electricity spending is typically comparing apples and oranges. You want to include the natural gas or oil or whatever else people are using for heat if you want to get numbers that are even remotely comparable.
I have a family of 5 in a small home and we spend $1200/yr in pricey CA (rates start at 16c/kWh going up to 35c). We don't run AC (whole house fans/attic fans), and use room heaters in winter.
