Energy usage wise, they are the same. That is why the units match after conversions. In any case, I replaced substantial energy usage from heating oil with less substantial use of electricity. Here is a fun fact. It is more energy efficient to run a heat pump off electricity from a commercial generator burning diesel to heat a home than it is to burn the diesel directly. This includes grid losses. The reason for this is that heat pumps exceed 100% efficiency because the environmental energy moved is free as far as accounting is concerned. In my case, the electricity is produced by burning natural gas rather than diesel.
By the way, I realize my numbers are borderline in showing that, but the past year has been colder than years where
I burned oil, and it is hard to account for that when looking at numbers as there is no strict control.
