A refresher in thermodynamics is in order here....thermal energy is...energy, which is a conserved quantity. Heat doesn't just disappear. An air conditioner cools the inside air by making the outside air hotter.

And (thermodynamics strikes again) it also creates yet more waste heat in the process.

Doesn't matter how free people or the markets are, thermodynamics is for real. We are not air-conditioning our way out of this.
