In most of the United States today, such low-tech cooling techniques have essentially disappeared, to such an extent that when our houses feel hot to us we don’t even bother to draw the curtains, but instead reach for air-conditioner controls. One result, Cox has observed, is that we now use roughly as much electricity to cool buildings as we did for all purposes in 1955. Another is that a room that used to be a standard feature of houses in many parts of the country, the screened porch, has become far less common. (If you don’t have air-conditioning, the screened porch is usually the coolest room in your house: it’s where you go in the evening to beat the heat. But once you do have air-conditioning the screened porch immediately becomes the hottest room in your house, and often seems unbearable by comparison. Once people who own old houses have added air-conditioning, they often enclose, air-condition, and heat their porches, so that they can continue to use them, year-round, without feeling uncomfortable. Energy use begets energy use.)
