Very true thats why I mentioned the losses are at the generation station. Still 100% in the home, so the loss isnt to the homeowner except in the bills. If hydro and nuclear were used more than coal (53% of the time) I would guess more of us would use electric heaters.
One somewhat interesting thing I learned from the DeLonghi space heater experiment is how much energy was needed to maintain a steady state temperature (68F) in the house with an outdoor temp of low 20s day and night. Turns out it is around 2.7 kilowatts @ about 6 cents/kwh. Not bad for a 1973 doublewide? LOL
