In the late 1970s, 23 percent of American homes had some form of air conditioning; today, 87 percent do. We have become so addicted that 9 out of 10 new homes are built with central air. We spend $40 billion a year air-conditioning our buildings, says the EPA, and cooling our homes accounts for 17 percent of household energy use.
In return, we get — well, I’ll let author Stan Cox say it: “Air-conditioning buildings and cars in the U.S. has the climate impact of half a billion metric tons of carbon dioxide a year. That exceeds the total annual carbon dioxide emissions of any one of these nations: Australia, France, Brazil, or Indonesia.”
Wait, you mean the thing we use to get through the record heat is … helping to cause the record heat? I believe that is what the kids call ironic.
