AC isn't that energy expensive. People just think of it as a 'luxury' and assume it must use more power, or they're used to how car ACs destroy gas mileage (but running any electrical appliance off a car engine is very inefficient)
Running an AC in a warm part of the world consumes vastly less power than heating in a cold part of the world does. Moving south reduces GHG emissions, all else being equal.
