From this page in the New York Times, dated June 21, 2012:
Should Air-Conditioning Go Global, or Be Rationed Away?More HERE, including the following:
Temperatures in New York City have pushed toward 100 degrees this week, and air-conditioners strained the power grid (thanks in part to stores with their doors open). Meanwhile the demand for coolant gases, especially in rapidly developing countries like India, threatens to accelerate global warming.
Is it a good goal for everyone in the world to have access to air-conditioning — like clean water or the Internet? Or is it an unsustainable luxury, which air-conditioned societies should be giving up or rationing?
...[T]here's little we can say until we end our own society's dependence on lavish cooling. Doing that would be a good start, but addressing energy-hungry technologies one at a time won't achieve the greenhouse-gas cuts of as much as 80 percent that science says are necessary to prevent catastrophic warming. Only a per-person ceiling on overall emissions can accomplish that.
