Even if provided electricity by gas turbine, it’s more efficient to burn that gas in the turbine and deliver electrons to the stove. Coal is dead by the end of the decade (only one coal fired generator, “Dry Fork”, in Wyoming is cheaper than new renewables in the US).

From there it's a simple calculation of heating need vs efficiency difference to determine which is more efficient in a particular use case.
