That's not been my experience and I live north of 46 degrees latitude, with an average December temperatures much lower than, for example, Abilene, TX, with a total electric bill in the neighborhood of ~$250/month in December/January. The Coefficient of Performance for electrical resistance heat, and natural gas are both 1.0, (so you need the same number of joules to heat the air to the same temperature from either energy source). Maybe electric rates are really high in Texas in the winter? Or the gas rates are really low, and the house is huge?
