I have been doing some reading recently about food production, processing and fuel usage. Some interesting findings. The Economist did an article on it a few weeks ago.
They concluded that tightly packed crates of food delivered to the store near you in containers probably used less energy, or in this case petroleum, than the SUV used to drive to the corner store to buy the groceries.
And there is less waste in terms of spoiled produce. Also a factor. Spoiled food is of no use to anyone, but it still takes land, water and energy to grow.
Also, I am lucky to get German TV via satelite and they seem to do a lot of programs on food processing. I am struck by how efficient these factories are. I am also convinced they are far more fuel efficient than having decentralized processing done in many smaller batches.
I will agree that if we run out of petroleum that long distance transport of perishables will cease to happen.
However, stationary sources of power will still run much of the food processing done to preserve food. It is simply way more efficient than human labor. Labor that also has to be fed to keep it working.
And I think ditto for water usage. Yes, these plants use a tremendous amount of water for processing, but divided by the sheer tonnage of food processed (or however you measure it) they are very efficient.
Basically, the Germans are legendary engineers, which is probably why they lead the world in exports two years in a row now, but one machine easily does the work of hundreds of workers. And that is a huge saving in terms of manpower and expense not to mention making food cheaper for the consumer.
I do not see peak oil depletion as changing that. We have used a period of cheap energy to introduce best practices into food manufacturing as well as spreading crops to many countries from their country of origin, and this somewhat insulates us from crop failure in any one region of the world.
How we grow food will no doubt have to change. Especially western practices dependent on artificial fertilizers, irrigation and petroleum powered machinery. And long distance trucking will have to be replaced by rail and water transport. That means central depos and local distribution. Maybe even by bicycle or horse drawn wagon if necessary.
But in general I do not see mom and pop shops popping up everywhere to replace modern factories that operate that much more efficiently. Remember living standards will be declining with less energy. So the most efficient plants will be even more important. There really is no going back.
Now, if we run out of all conventional sources of energy and there are no alternatives then we might be well and truly out of luck, but even then I suspect centralized factories with solar power will still be more efficient than everyone doing everything manually again.
The organized state is a wonderful invention whereby everyone can live at someone else's expense.
