1. How much energy is required to manufacture a bicycle/laptop/automobile/solar panel? Are we talking about oil or electricity?
Rembrandt responded,
which production methods? factory assembly?
I suppose it varies between products. For a laptop, I would say factory manufacture of the parts. I (or my wife, who is more talented at putting those little bits back together -- she fixed her own powerbook once) could put the parts together at home. For a bicycle, I'd also say factory manufacture of the parts. For an automobile, I guess you need the whole thing -- some people know how to assemble autos from kits but most people aren't willing to invest the time. For a solar panel? I have no idea.
At any rate, the factories could be right here in California so transportation could be minimized. They already make cars here -- it wasn't too long ago that all of those other things were built here as well. Also, California (and much of the U.S.) has a great culture of restoration -- of cars, bicycles, et cetera. Some people love to do it themselves, even when they don't need to. Maybe part of the transition to the future economy will involve a renaissance in that culture.
BTW, I've been reading the book, "Prosperous Way Down," by Howard T. Odum and Elisabeth C. Odum. Fascinating stuff. I don't think I fully grok the way emergy works but it's definitely an interesting idea.
I'm trying to visualize the San Francisco Bay Area economy (not Mad Max, I hope) of twenty or thirty years from now.
