Air Conditioning: Our Cross to Bear
About 5.5 percent of the gasoline burned annually by America's cars and light trucks -- 7 billion gallons -- goes to run air-conditioners. That's equivalent to the total oil consumption of Indonesia, a petroleum-rich country with a population size comparable to ours. Four states -- California, Arizona, Texas and Florida -- account for 35 percent of that extra fuel consumption Fifty-six percent of refrigerants worldwide are used for air-conditioning buildings and vehicles. North America, with 6 percent of the world's people, accounts for nearly 40 percent of its refrigerant market, as well as 43 percent of all refrigerants currently "banked" inside appliances and 38 percent of the resultant global-warming effects.
Finally, in counting costs, it's important to consider not only fuel and refrigerants but also the materials -- steel, copper, plastics and a lot more -- that have gone into building up the nation's colossal tonnage of air-conditioning capacity.
