I don't even look at my actual cost of Kw hours. It's not relevant at all.
(I think it might be around 12 cents?) I always recalculate the kwh rate using the total cost.
Which is currently between 20 & 21 cents per kwh..
The Efergy power monitor connected to the Sanyo rounds off to the penny,
so I just use 21 cents, to keep it ballparked.
We spent $11.30 cents last week. $1.61 per day to heat this house.
That is
way less than burning a few gallons of oil every day..
