Cool it
We find our climate too warm, and cool ourselves,
Thereby making our climate even warmer.
In 2007, the United States was using 13 percent of its
Total electricity consumption to run its air conditioners.
This amounted to 484 trillion watt-hours of electricity,
About equal to the electricity used for all purposes
By all of the nearly one billion inhabitants of Africa.
The air-conditioning of buildings in the United States
Emits an amount of carbon dioxide equivalent
To that which would be produced, were every
Household in the country to purchase an additional
Vehicle, and drive it an average of 7,000 miles a year.
Air-conditioning is now central to the structure of
Our society. It has driven the recent migration of
The population, principally of the white and wealthy,
Southward, helping make possible the present
Shift to the right in the country’s political center.
Since 1928, when central air-control was installed
In the Capitol, bi-partisan consensus on the matter
Has not wavered. And no one has suggested that
President Obama appear before the Nation dripping
In sweat as he explains to us our energy predicament.
Would American commuters, who, in 2005, spent an
Average of 38 hours in traffic stoppages, during which
They used more than 3 billion gallons of gasoline, not
Be in open revolt, were it not for air-conditioning and
Other comforts now integral to the definition of a car?
In homes, air-conditioning in the master bedroom
Has priority, and indeed, cooler air has smoothed
The seasonal fluctuation in conceptions, previously
Characterized by a low during the summer months –
A decrease in sexual activity the most likely cause.
Cool, moderately humid, clean air, with outside noise
And danger shut out, is one of the country’s top-selling
Non-pharmaceutical sleeping aid, appreciated by the
64 percent of us who suffer from chronic insomnia, and
Especially the 41 percent with problems almost nightly.
During Arizona’s record-breaking 2003 heat wave,
Hard-line Sheriff Joe Arpaio kept the 2,000 inmates of
Maricopa County Jail in tents without air-conditioning.
The temperature was measured at 138 degrees.
In an annex, an animal shelter was air-conditioned.
Badly-behaved children, especially if underprivileged,
Can be made to spend the summer in an air-conditioned
Classroom. Our Nation’s “human capital” is thus protected
From venting its aggressiveness and lack of focus, in
The wild, where it might be out of the reach of Ritalin.
In retail, the higher the prices, the lower the temperature.
Among the Manhattan clothing store, Bergdorf Goodman
Keeps its temperature at 68 degrees, and Bloomingdale’s
At 71. Between 1995 and 2003, the Nation’s retail sector
Increased by 66 percent the energy it uses to keep cool.
In the meat industry, a temperature brought down
To 50 degrees brings bacterial reproduction almost to
A halt, thereby obviating the need for a mid-shift
Interruption of production to wash and sterilize
Equipment. Profits increase despite high electricity bills.
In Afghanistan and Iraq, our troops could not survive
The summers in enclosed, heavily armored vehicles,
Such as the Humvee, were these not equipped with air-
Conditioning. In 2008, 85 percent of the diesel fuel
Used by forward bases, powered air-cooling systems.
In Matamoros, Mexico, where only 32 percent of homes have
Air-conditioning, 78 percent of residents are infected with
The mosquito-borne dengue virus. Across the Rio Grande,
In Brownsville, Texas, where 83 percent of homes have
Air-conditioning, just 40 percent of residents are so infected.
In 2006, our information technology equipment (residential,
Commercial and industrial computers, and accessories),
Used 6 percent of our total electricity consumption.
This was around 219 trillion watt-hours – approximating
The total consumption of electricity by Australia, in 2005.
A good share of the electricity we use to run the
Internet, is aimed at convincing users to consume more
Of everything. Between 2002 and 2008, revenues
From Internet advertising nearly quadrupled. Of all
Internet traffic, 25 percent goes to retail sites.
The limiting factor to data processing performance is
Cooling technology, liquid now replacing air for cooling.
It is likely, however, that improved cooling capacity will
Be used to further expand computer power, keeping its
Present uses, not in order to reduce our energy footprint.
Air-conditioning does not feature any prominent
Culprit – individual, corporate, economic or political.
It has insinuated itself into the fabric of our society,
Airily contributing to our present unsustainability.

In 2005, Mexico’s total electricity consumption was 183 Terawatt-hours (trillion watt-hours, 1012 watt-hours), and Australia’s total electricity consumption was 219 Terawatt-hours. In 2008, total consumption in the United States was 3,873 Terawatt-hours. According to Cox (p. 153), this means that, around 2005-2008, in the U.S., computers and peripheral equipment used between (183/3,873) 100 = 5 percent and (219/3,873) 100 = 6 percent of total electricity consumption.
I have refined this estimate in the following way. In 2001, the Lawrence Berkeley National Laboratory estimated that our information technology equipment used 3 percent of our total electricity consumption. According to Cox (p. 153), in 2006, the Environmental Protection Agency estimated that network data centers (large computing facilities which do much of the work of the Internet, as well as process bank and credit-card transactions) had doubled since 2000. The refined estimate for 2006, therefore, is that, in the U.S., computer technology uses 6 percent of the country’s total electricity consumption.
The figure quoted in the poem is 219 Terawatt-hours, in 2006 – 6 percent of total consumption – equivalent to total electricity consumption in Australia, in 2005.
