Electricity fails far more often than natural gas - I've never experienced a natural gas failure in 48+ years. I suppose I should be prepared for one - but freezing weather is still rare in this area, its not such a hardship to be without a source of heat as it would be in Minnesota or Vermont.

Gas fireplace in the living room and gas hot water heater, both with piezo electric ignition, meaning they will do their jobs. We lose electricity, we lose light, but we retain a source of heat and hot showers.
