The primary use of natural gas is heating and in moderate climates burning natural gas to heat your house is under half as efficient as burning natural gas at a power plant, moving the electricity to your house, and using a heat-pump to move the outdoors heat inside. Making houses energy-agnostic seems like a big win if the cost is low and it can be, especially on new constructions. Plus if you assume that natural gas is bad then it should be obvious that thousands of houses directly depending on it is much worse than indirectly depending on it via the local plant. The local plant centralizes safety and pollution measures (e.g. no domestic gas leaks) and it allows a much quicker swapping of energy sources by the city when the time comes.
