I see three of the four nukes in TX are still running:

I think we can conclude that it the average Texas home, the air conditioning mode uses less power than the heat mode.
If it were just heat pumps then the load should be sort of matched. Albeit a heat pump is not match for sub-32 temps.
IT IS THE ELECTRIC HEAT that is NOT USING A REFRIGERANT in the process that is killing the state. Most baseboard heater use much more than the comparable air conditioning does.
Watch the liberal solution be to BAN electric heat strips and baseboard heaters !!
