We live north of the Black Hills in South Dakota. Winter can be cold here at 45 degrees latitude but we can usually get by with four to five cords in a 1500 sf main floor area. Our house is not an open plan so it is hard to heat the bedrooms and you get uncomfortably hot in the living room.
I am getting older too and don't like splitting and hauling wood as much as I used to. These days we have backup heat with both forced air propane and electric with the electric being the best and cheapest. The electric heat is probably the best for us as it is controlled in each room.
I keep two years worth of wood around the place in case of power outages but am likely to go to the electric heat more and more and just keep a couple of months of wood around.
