DFW and Houston have immense amounts of office space, and office space consumes a ton of climate control electricity. Houston has warm-to-hot summers and awful high humidity, so AC is absolutely required. DFW has less humidity, but much higher summer temps. AC very much required. DFW also gets really cold 1-3 months of the year. And maybe it's my limited observations, but I would say the temperature swings have been more extreme in the last decade. Years ago I lived in Fort Worth in a typical large house. My winter electric heating bill was $450/mo. My summer AC electric bill was $400/mo. The hum of climate control units is constant. Depending on where you live in Texas, there can be 1-3 weeks of spring or fall where you need little climate control. The rest of the time it's all on.
