The point is that Houston is both hotter and more humid. People have already died due to heat because of this loss of power. The AC is not a luxury but a necessity.

I'm not commenting on the usage of ac in Houston (albeit it's nonsense to raise a city in such a place) but in Rome.

Perhaps your original comment made it to the wrong post? This article was about the problems Houston is having from power and AC being out for days so people are naturally expecting comments and their ensuing discussion to also relate to this.
