I'm not convinced by the author's point that ACs do not impose a burden on the electrical grid. They write that ACs have gotten more efficient, which may be true, but that's the same Windows developers have been saying over years and yet boot times and hardware requirements have gone way up. One million efficient units still require more energy than no units. And while I definitely believe that European hospitals and retirement homes sadly need ACs now (thanks global warming), I'm not sure everyone and their dog needs one.
I also have reservations about why an American libertarian think tank writes about what Europeans should do, but that's probably on me.
