That's funny, I think I got the figure for that from the SolarCity website. Oh well. My April bill is out on the table (I'm not a great housekeeper), and shows 484 KWH (5808 annual; I have central air, but rarely use it). This is a century old two storey farmhouse with what's left of that injected foam insulation, fuel oil heat with forced air furnace, and I also pump a 200 foot well for my water.
http://www.teslarati.com/tesla-monthly-charge-cost-calculator/[snip] To understand Telsa driver behavior, Teslanomics tapped into the brilliant team behind the Teslab app which we reviewed in the past. Teslab has real-world efficiency data from their Model S and Model X-owning app users. Per Ben Sullins of Teslanomics, Teslab is “like a fitbit for your Tesla” as it provides insights into how you operate your vehicle.
In this case, the data showed that most drivers use approximately 300 watt-hours per mile as the “normal” efficiency achieved by Tesla drivers. [/snip]
[That's .3 KWH times 300 mile range for 90 KWH, although these are not the Model 3]
