In general, we use about 800-2000kWh per month, though I've had higher months during cold spells (peak was 2333kWh during a really cold month).
It's a 2000 sq ft manufactured home, so fairly energy efficient but not "exotically efficient" by any means, and we have a pretty wide range of temperatures during the year - over 100F in the summer, down below 0F in the winter.
We also have a somewhat deep well (I think water is around the 230' mark, though I should probably put something on to monitor that) that all our water comes from, including irrigation for the gardens and such.
Our house is "pure electric" - so hot water is electric, heating is electric (we have a heat pump that covers most of our needs, though it will kick the backup coils on in the winter months - I should see if I can find the performance curves for our heat pump because I may be running it below a COP of 1 in the winter some mornings), backup heating is electric ("coils"), we pump our own water, etc.
Given that our power is super cheap (50% hydro, and otherwise cheap), our power bills aren't particular expensive - the 2.3MWh month was only $200 for the power bill. Given how well the Nest runs our heat pump vs the dumb thermostat that came with it, I'm convinced the Nest paid for itself in that first winter alone.
There's another 5-10kWh/day that goes to my office, but that's off solar, so it doesn't impact our power bill (my office is entirely off grid, and is pure solar for most of the year, with about 5-7 gallons of gas for the generator and around 5 gallons of propane used for power and heat in the winter).
I'm planning to reduce our power use somewhat, but not really for "saving money on the bill" reasons - more for redundancy and anti-fragility. Eventually, I want a wood stove in the house for backup winter heat, as well as for heating on those really cold days when the coils are running. My wife is a fan of radiant heat and roasting herself (her parents heat with wood, and run the house uncomfortably warm by my standards, so I get where she's coming from), so adding that capability is a nice creature comfort as well. New wood stoves are incredibly efficient compared to older ones.
I'm also putting solar on the house next year (well, on the property - ground mount), which probably won't pay off as I'm doing a DC coupled off grid capable system - but I'll be able to run off grid for long periods of time as well. I'll probably (eventually) interconnect my office and home systems so they can support each other as needed.
I may play around with some of the window insulation stuff this winter, but our windows are fairly efficient to start with and I'm not sure there are huge gains to be had insulating the windows.
