$this->bbcode_second_pass_quote('ennui2', 'E')IA may be inaccurate, but it doesn't change the fact that we're not facing empty store shelves and zombie hordes the way the old posts in this thread predicted.
Indeed I consider myself a Moderate and I used to argue endlessly with MQ about lifeboat rules, fast crash doom, solutions in isolation... There are ways we could end up in a fast crash scenario, but I don't see Peak Oil itself as one of them. I also see the community building effort as being much more valuable than the lifeboat rules where you pick who to throw overboard in a vain attempt to isolate yourself with enough resources to survive.
The fact of the matter is we used to discuss Jevon's Paradox a lot around here, but I think we missed something crucial. I am reminded of the scene in the Tom Hank's Apollo 13 movie, Gene Kranz is talking to his crew of engineers and says "I don't care what anything was designed to do, I care what it can do"
Land based Fission power was designed to produce electricity. It also produces a lot of high grade heat, even more low grade heat, valuable radioisotopes, valuable stable isotopes and probably other things I am forgetting, but because it was DESIGNED to produce electricity we ignore all the other possibilities.
Another example, rooftop solar both water heating and PV. A properly designed and installed system can be built with an air gap between the roof top and panel assembly getting double duty out of the installation by directly shading the roof reducing summer heat accumulation without much difference in winter heat retention properties. If you are doing new construction you can pitch the system at the optimum angle for solar gain instead of just going with a standard roof pitch. For solar hot water you can install a 'wet wall' where the south facing (north facing in the southern hemisphere) exterior is a very deep wall with a network of piping just below the exterior skin that absorb the solar heating that hits the wall. If you properly insulate the pipes then over about 80 percent population centers of the USA you can have free hot water even in winter without risk of the pipes freezing. In the USA roofs or 'designed' to provide weather tight enclosures without a thought to shading, properly insulating or much of anything else. I read a study not too long ago about a builder who by simply building a double roof with an air gap greatly cut down on summer solar heat gain. From the exterior it looked like a standard house, but if you went into the attic there was an insulated ceiling on the south facing roof with an air gap of several inches between the exterior roof and itself. The extra cost was about 1 percent of the project, but the cooling efficiency increase was claimed to be 15 to 25 percent depending on cloud cover.
Another example District Heating. Common in Europe but rare in the USA where a central boiler system creates steam and/or hot water and distributes it for blocks in all directions like any other utility. A central boiler producing the heating is much more efficient than dozens of buildings each with its own heating source operating independently in winter. It does have its drawbacks I can speak from experience about the 'inconvenience' of having heat got out on December 23 and stay out for 5 days due to mismanagement. That wasn't district heat but the principal is the same, when you rely on others for crucial needs you have to all work together for everyone's benefit. The best thing about district heating IMO is it can be used for cogeneration, generating electricity as well as heating. There was a big push back in 2005 when Natural Gas around southern Michigan and northern Ohio zoomed up to $11.75 for large institutions like public schools and hospitals to install modern cogeneration systems producing both electricity and heat instead of just heat. When the price of natural gas crashed the push went away, but it should have kept going.
A big SUV is 'designed' for off road use but for the most part they never leave the paved road network and many of them spend the majority of their travel with a single occupant, the driver. How would you improve that wasteful capacity if you had never spent a moment thinking about it and suddenly you are faced with Peak Oil and fuel rationing?
School buses and city buses are both designed to haul many people along fixed routes. Why have duplicate systems? Most small municipalities have schools with buses but not public transit. With a little thought the system designed for busing children could serve as mass transit during those hours of the day when school children are in class and before and after school when not needed to bus pupils around. Even better they can operate all summer and during school vacations providing mass transit. All it takes is some proper thinking about how to best utilize a resource tax payers are funding in both cases instead of wasteful duplication. You can even do it the other way around, instead of the school owning the buses the city owns the buses and the school contracts them to run school routes at fixed times giving the students free transportation.
Every one of these is a solution in isolation that does not cure all the issues and in some cases creates different issues, but all together they add to one another to provide the kind of flexibility required to muddle on through.
