We are all seeing the rise in fuel prices affecting food prices. I would like the readers to do a acres of farm to miles traveled evaluation of their plans when planning for a world with sparse petro-fuels.
The current option is to ignore the prices and continue to fuel large SUVs and pickup trucks even for for “pick me up milk” runs.
A fuel efficient car or motorcycle makes more sense depending on the number of passengers travelling.
Bio-diesel or ethanol from your field rarely makes sense for anything other than a few very important drives per year or towing a harvester, the effort to farm these crops are better fed to work animals and
human workers. Although if you really only make these few drives it might even out considering you make one or two batches of fuel and garage the truck the rest of the year, no daily feeding of a huge hungry beast.
Horses and oxen are very useful on a large post-petroleum farm, replacing the tractor and truck, but you need to feed that large living muscle mass even in the dead of winter when there is little
important(to your survival bottom line) travel or work. It is important to remember that even into the steam age before bicycles and automobiles reduced the number of work animals around half of the US farm output went into the mouths of work and transportation animals. Even if you are able to graze in the fair months of the year most Americans in the northern
states need to have plans to safely mow and store large amounts of hay and grains to feed your livestock. A donkey or mule is smaller and must pull a smaller plow or load but in the off months they are
a smaller idle eater and need less exercise to stay healthy and content .
The last stop in labor is the human body, around the world many poorer peoples use themselves as farming machines. You will see a man pulling a plow with his wife or child steering. A bicycle converts muscle energy many times over saving calories and time for longer range travel, as long as the bicycle can be maintained. The trick with human energy is we don’t slaughter ourselves if times get tight, and we can still do useful work even in winter when most work animals are idle eaters. This is why the farm family has always rejoiced in another new baby, not only was it filling the command to be fruitful and multiply but it was another helping hand.(Have you ever noticed that the more religious families even in urban areas often have many children?)
On the plus calorie side chickens, goats, sheep and larger free grazed food animals add calories to your bottom line by metabolizing insects, kitchen scraps, and cellulose like grass into food that humans can easily consume. We need not say that the beast deal is gathered fruits, honey, netted fish, and hunted or tapped nutrition which require tiny amounts of exertion compared to the calories obtained.
