It's probably useful to take a broad look at the efficiency of electric heat. Considering that running a coal generator is only slightly above 30% efficiency, hence throwing away 70%. Then considering the line loss between the generator plant and your home, which is often discussed as around 10%. Then to further discuss the inefficiency of electrical resistance heating, which, I understand is only about 35%, then the whole picture of electrical heating fuel waste comes into perspective.

So, lets add anothr question to this. Does it make sense to lower the temp at night in the home or leave it set at the same temp day and night? The thought is by lowering it 3 to 4 degrees at night while your asleep, it would run less, but then if the heatpump has to fire up the backup heat source which is likely electric itself and run at the same time to raise the temp up the 3 to 4 degrees, have you really saved anything.
