Admittedly, January is an odd time for an article on air conditioning for a publication whose readership is mostly in the Northern Hemisphere. Makes sense though for those in Australia where you have probably become a carbon cinder in the last few days. But this Economist piece on the pros and cons of air conditioning is pretty interesting. The short of it is that air conditioning is great for you but awful for everyone else given the massive amount of energy they use and the effect that has on the planet, where the poor suffer from ever greater heat.
On principle, I am highly skeptical of technological fetishism that assumes better technology will solve all our problems. But this is one area where some technological advancements in air conditioning would probably save a ton of water and power. It also reminds me of how odd I continue to find it that rather than capture the manufacturing of wind energy and profit from it, oil companies want to destroy it. Why not take the lead on the future of your market? Of course the answer is short-term profit.
