Americans today are generally aware that we consume far more energy per capita than most of the world’s peoples, over four times the world average and double that of regions like Japan and Europe which enjoy a similar standard of living. Most of us reflect on home gas and electric bills plus the fuel pumped into our cars’ gas tanks when judging our personal energy footprints.
But in reality it is all the “stuff” Americans accumulate that contributes most heavily to our total energy consumption. To understand why this is true, it is necessary to first get a handle on the ways societies utilize energy.

By convention, the energy-consuming activities of society are divided into the four sectors described below: residential, commercial, industry and transportation. The pie chart below shows the percentage of total U.S. energy delivered in a year to each sector, according to recent U.S. Energy Information Administration figures. Note that the very same pie chart describes the average per capita energy consumption of Americans in the four sectors.

The residential sector reflects the energy used to run our homes (to power lighting, appliances and heating & cooling systems) and, at 15 percent, it is the next to smallest pie piece. At 40 percent, the transportation sector is largest but includes all energy inputted to move both people and goods about, be it by car, truck, train, plane, boat or pipeline. Given that about half this amount goes into shuttling people, this means that personal transportation and running our homes together account for only about 35 percent of the energy we Americans use.

An additional 11 percent goes to meeting the energy demands of commercial/institutional buildings which constitute the entire service sector of society – businesses, organizations and institutions including schools, hospitals, correctional facilities, stores, restaurants,  theaters, etc. – all of which expend energy for lighting, temperature control systems and appliances like computers and faxes. Though relatively modest, the energy that supports these shared facets of society is overlooked by most of us when contemplating our energy footprint.

And also generally overlooked is our personal contribution to the industry sector which, at 34 percent, is on par with the energy sunk into running both our homes and vehicles. This sector covers the production of all the “stuff” that makes up the typical American lifestyle, everything from hamburgers, clothing and golf clubs to dishwashers, pharmaceuticals and satellites, plus all the factory machines that make stuff…virtually every manufactured or processed object you can name. The energy used at every step in production is figured in, starting with extraction of raw materials to final assembly.

And, when you figure in that roughly half of transportation sector energy is funneled into moving raw materials and goods about the globe, a solid half of the energy that supports the American lifestyle is for making and bringing to market all manufactured and processed goods.

A run-down of the energy-sapping steps involved in the production of a hypothetical polyester/cotton blend T-shirt, abstracted from the book “Stuff: The Secret Lives of Everyday Things” by John C. Ryan and Alan Thein Durning, drives home the point.

The shirt’s polyester component derived from a few tablespoons of crude oil pumped up from a mile-deep well in Venezuela and shipped to a refinery on the island of Curaçao before being piped into a 12-story steel cracking tower where the many different hydrocarbons which make up the crude are separated out. Additional oil was burned to heat the crude to the 750°F needed to yield petrochemicals like ethylene and xylene from which polyester is synthesized.

Those chemicals are then shipped to a chemical plant in Delaware where high temperature processes convert them to intermediary chemicals which, in turn, are linked into long molecular chains of polyethylene terephthalate (like the PET in plastic beverage bottles). Polyester fibers are formed by drawing out the PET resin into hair-like filaments.

Growing the shirt’s Mississippi cotton is also energy intensive from the start because of the heavy irrigation (electrically-driven) and frequent dousing with synthetic pesticides that is standard practice in the cotton industry. In addition, a crop duster burning diesel fuel from Mexico applies a defoliant before harvesting. To pick the cotton, a worker sits in the air-conditioned cab of a diesel-powered cotton stripper manufactured in the United States from parts imported from 20 countries. Once a cotton gin separates the fibers from the seeds, the fibers are trucked to a textile mill in North Carolina to be spun into yarn.  Another mill knits the cotton and polyester into fabric.

A woman in Honduras sews the T-shirt which is mounted on a sheet of cardboard made of pinewood pulp from Georgia wrapped in a polyethylene bag made in Mexico. The finished product is shipped back to the United States where the consumer most likely carts it home in a plastic bag made in Louisiana.

The point here is not that anyone who cares about energy conservation should never buy a T-shirt, but rather the T-shirt saga illuminates how an individual’s purchasing habits contribute so heavily to his/her personal energy footprint.

Given all the hidden energy embedded in manufactured and processed goods, Americans will ultimately need to do more than add solar panels to our rooftops and drive fuel efficient vehicles to transition away from a fossil fuel-based economy and to mitigate global climate change. We will need to accept that a culture and economy based on endless consumption of stuff is simply not compatible with a rational solution to our nation’s energy dilemma.

But it won’t be politicians asking us to consume less of what we don’t really need that will lead to a more sustainable energy culture. Nor should we expect that industry will any time soon label products with the amount of energy used to produce them, though it would empower consumers to make smarter energy choices.

Instead, culture change must come from ordinary people who choose to resist buying on impulse and shopping purely for the sake of entertainment, people mindful of the energy wasted in a single superfluous T-shirt.

    Steve, great job. Illuminating and challenging. I believe that for one to make the changes that end such energy waste and poisoning of our world, one has to want a better life that celebrates nature and human closeness. As isolated consumers working for bosses and lacking the strength of a village community, and bullied by infotainment, Madison Avenue and terror alerts, it’s as if people have lost the ability to think, question and act. Deer eyes in the headlights, grateful for the petroleum-derived food that will give out with petrocollapse and climate extinction. Meanwhile, better ways of living — simply and in solidarity with mutual aid — are suppressed and needlessly feared. Your report helps people wake up. Thank you.

  2. Jan – thank you for your kind words and admirable insight into global environmental issues about which you have been writing long before most of the rest of us. To keep abreast, I direct readers to your website: http://culturechange.org/cms/index.php

    Belatedly I reply: This post rocks. I drive all-electric cars powered by residential solar, and maybe that gives me a better grade than my SUV driving, pool-in-the-back-yard neighbor. However, I consume, consume, consume and then consume. some more. It is so easy to get sucked into this out-of-control consumerism that we Americans have been hypnotized into feeling makes for a happy, fulfilled life. Thanks for reminding us of the truth.

    Thank you for the article, Steve/Sarah, and the comments, Jan and Linda! This is clearly a hinge point in our 2000 years of “civilization”, where an energy source that has enabled global populations to quadruple in the last 100 years will soon be no more, leaving us with both dirtier and cleaner sources of energy (coal and renewables).
    The choices we will make are critical, and I would like to contribute some designs that occurred to me as I staggered, walked and jogged more than 330 miles to recover from the effects of my heart stopping for 10 minutes following a car accident in Kenya in 1980. Please view them at http://www.greenmillennium.eu and I challenge you to do even more! If I can produce the ideas on the website while recovering the abilities to walk, speak and remember, just think of what you can do!
    Let’s make the 100% sustainable future together, for the components of our genes, which have existed in all of our ancestors, and will continue in all of our descendents, making them eternal!

    Thank you!

    Kim Gyr
