Eating Oil : How Much Energy is Required to Bring you your Food?

Chad Heeter’s article about his Saudi Arabian Breakfast has been posted and reposted in numerous places and it’s an interesting read. How much oil goes into bringing you the food that you eat? More than you might think. Chad concludes that with his breakfast granola, he’s consumed the equivalent of over two quarts of Valvoline. The basic problem with our modern food supply is that an average of over seven calories of fossil fuel is burned up for every calorie of energy we get from our food (some researchers claim the ratio to be as high as ten to one). This means that in eating a 400 calorie breakfast, you will, in effect, have “consumed” 2,800 calories of fossil-fuel energy.

The following table shows a simple comparison of which types of foods require more energy (and therefore more oil) to produce vs. types of foods that require less energy.

Requires Less Energy Requires More Energy
Raw food, e.g. Oatmeal (ingredient: rolled oats) Processed food, e.g. Froot Loops (ingredients too numerous to list)
Unpackaged food, e.g. potatoes Heavily packaged food, e.g. individually wrapped french fries
Foods that can be stored at room temperature, e.g. flour Food requiring refrigeration, e.g. ice cream
Locally grown foods, e.g. people in Seattle eating apples grown in Washington state Imported foods, e.g. people in Seattle eating apples from Fiji

Shrinking Island of Kivalina

There was a story it today’s L.A. Times: An Alaskan island is losing ground. The small island of Kivalina has been shrinking for a long time — an 1838 explorer’s account said the island was about 3 times wider than it is now, but it is now being pointed at as the canary in the coal mine for evidence of global warming. The natural erosion has been going on for some time, but global warming appears to be accelerating the pace. What may be more telling than the vanishing shoreline is that the surrounding permafrost is fast melting. One resident discovered that his caribou and seal meat had rotted while in his cold cellar — a deep hole in the ground where meat is aged over the summer. The surrounding permafrost had melted and filled the pit with water.

Faced with the constant erosion of the protective seawall and the danger inherent with any coming storm, one resident stated “we’ve got to get off the island. It’s obvious.”
