And that led to thinking about what is it that actually runs off it?
Fridge, dishwasher, clothes washer, lights, hmm, nothing there to explain the 1500 kWhrs a month.
Phoned the electric company, surely this bill is wrong?
Thought a bit more, looked around – ah, that 2000W electric oil heater’s been getting a bit of use hasn’t it? Think it through, look up energy consumption numbers, prices, umm – yes, that probably is it.
Sigh. Only took 3 months to work it out. Sigh.
