Some are choosing the summer breeze over the whir of the air conditioner

Summer breeze, makes them feel fine

The Times detailed the experience of one Nashville, Tennessee family, among others, who went an entire summer without air conditioning -- despite Nashville's intense heat and humidity -- and saved about $2,100 in summer energy expenses in the process.

The family adjusted to it so well and likely its benefits -- the family ended up spending more time together -- that they've continued the 'air conditioning-free zone' this year.

Economic Analysis: Could citizens pulling the plug on air conditioning represent another, credible way for the United States to reduce its per capita energy consumption? In theory, yes, but as a practical matter, for much of the U.S., no. In cooler regions, such as the Pacific Northwest, upper Midwest, and northern New England, residents use less air conditioning. But it's hard to envision the South en masse turning back the clock and choosing to go without air conditioning. Likewise for businesses just about everywhere in the states. Certainly in cities like my New York (one of the climate world's most intense urban heat islands), they'll be no trend toward pulling the plug. The tactic could also represent a health hazard for the elderly, those with breathing conditions, and could endanger a pet cat or dog.

A more-reasonable energy saving tactic: replacing old air conditioning units and systems with newer, more-efficient equipment, and taking modest steps to cut energy consumption, such as raising the thermostat a few degrees in summer.

France is one modern, developed nation that has long had comparatively low per capita energy consumption levels from air conditioning, particularly in August. But there's a cultural reason for this: for the entire month of August, most French citizens are on vacation at cooler locales at the shore or in the country, and are not at their offices or at home.
