Living simply

My mother has mentioned her interest in living more simply, and several friends have brought up the subject as well. So I thought a discussion of what it means to live simply might be in order.

There isn't any one good answer, of course. It means something different to different people, and even at different times to the same person. People talk about clearing out clutter in their lives, and not buying things they don't really need, or moving to the country or to less stressful work. All of those can be part of living simply. What it means to me is to live as low as possible on the "embedded energy" scale.

People who work with alternative building materials speak of the embedded energy in different kinds of materials, the energy required to create that material and get it to the building site. The same is true of food and other manufactured items. Everything used by the typical consumer in the "developed countries" is the product of a long chain of other people's labor and of the burning of fossil fuels.

Let's use a loaf of bread as an example. Surely the simplest way to acquire a loaf of bread is to drive to the store and purchase it. But consider what went into putting that loaf of bread on the grocery store shelf. Land on which to grow the wheat, tractors to plow the fields, combines to cut the wheat, other energy-consuming equipment to thresh, clean and store the wheat, an energy-consuming mill to grind the wheat into flour, an energy-consuming bakery to create the bread, plus packaging for the loaf and energy for the retail store in which it sat until it was purchased and taken home. That list doesn't even begin to address the fuel burned for transportation of the grain, the flour and the additional ingredients of the loaf, and to move the loaf to its final destination. Or the cost of the pesticides used on the fields and the creation and transportation of their ingredients. Or the water needed for irrigation. Or the labor of all the people involved in each step along the way. Every one of these steps adds embedded energy to that no-longer-simple loaf of bread.

Now lets look at how one can move down the ladder of embedded energy. If I buy flour and make the bread myself, I've cut out the bakery and the trucks to move the bread from the bakery to the grocery store. If I buy grain, grind it myself and then make the bread, I've cut out another large group of energy consuming steps. If I could grow the grain myself, I could eliminate even more of them. So far, where bread is concerned, I have managed to move down the energy ladder to the point of buying the grain.

The same is true no matter what kind of manufactured item you talk about. The closer you can get to the raw materials of manufacture, the less energy is used in the creation of the item.

Some manufactured items obviously can't be made from scratch, including the computer I'm using right now. But the more things that get removed from the chain of factory-manufacture and large scale transportation, the more energy is available for things that are simply impossible for individuals to create for themselves.

Cutting down on the raw cost of the materials is one aspect of living simply. Labor is another aspect, and that discussion will have to wait until I'm not hours behind on work deadlines.

WHY 'LIFE AS A SPECTATOR SPORT'

"If you're lucky not to live in the gutters of a slum, but still can't afford to take vacations in the Alps, you're part of that enormous middle class who lives life through the medium of the television, further separated from "real" life by air conditioner, by automobile, by dishwasher, microwave and ice-in-the-door refrigerator, by automatic washer and dryer, and all the other appliances and conveniences that make it possible for America to live life at second hand. I'm not sure why Americans decided that televised drama was better than the real thing, that cardboard microwave food containers were an adequate substitute for real dishes, and their contents for real food, or that cooking, dishwashing and face-to-face conversation wasn't worth the effort and time it required. Someone fed this nation a plastic crate of out-of-season tomatoes and told us it was life and we took them at their word, and we're so much the poorer for it that it's hard to know where to start to list the shortcomings."


I wrote this a couple of years ago, but I have to admit it's much less amusing than I thought it would be to see the artifical construct falling apart.
