Gas and electricity in the same unit
A therm is 29.3 kilowatt hours of energy, so Delaware's gas works out at 11.00¢ per kWh against 18.48¢ for electricity.
That compares the energy you buy, not the heat you get. A furnace throws away a fifth of every therm up the flue, while a heat pump delivers two to three times the heat in a kilowatt hour — so the cheaper unit here is not automatically the cheaper way to heat a house.

Households in Delaware use 8% more electricity than the national average and pay 10% more than average. Cheap power absorbs most of that: the meter turns faster here, but at 18.48¢ each unit costs less than it does nationally. The climate is fairly balanced — 4,600 heating degree days against 1,200 cooling ones — so neither season dominates the bill.
