I'm not sure about that. I usually get about 125 gallons at a time. And since heating oil is just diesel with dye in it, we can just add deliver costs in gallons. Even assuming im the only delivery, I doubt it would take more than a gallon of gas to travel to my house. But to be safe lets say 5. With the above assumption, the question is Could 130 gallons burned at a power plant generate more heat in my house via electricity. Than 125 gallons burned in my house directly. I dont know enough to give an answer but my gut says no.
