I suppost after reading enough about Peak Oil and solutions to it one gets an impression of what would be necessary and what would not. I'll make some points and I'd encourage others to comment. This is just a dialogue I seem to have with myself now that I look at everything with Peak Oil in mind. Some of it sounds crazy compared to my line of thinking even 1 year ago and each would have quite a different answer then. Such as:

all buildings above 7 stories abandoned or cut down to size as a form of resource mining.

what is a hospital going to look like? How many do we need?

wholesale replacement of cars and trucks with bicycles trains and barges. Where can we get horses?

swaths of suburban areas cut up and replaced with walkable stores and healthcare offices. Replace houses sitting on still usable farmland.

A return of local farms selling directly to customers.

Alternative energy used to power water, sewage systems, cell and Internet given highest priority.

ban..er legislate technologies beyond a waste energy threshold per item (ie: incandescent light bulbs, Hummers) while also mandating increasing efficiencies. Start ending all energy subsidies.

Encourage energy conservation as common as recycling in the public mind as an action of responsibility.

Cutoff/demolish the southwest corner of a house into windows for passive solar heating. Start lighting buildings with sunlight, point windows in the general direction. Toss out the '60s housing development plans to be replaced with car-less communities.

force reduction in the carrying capacity of the city. When is a city full?

how many items that you need can be replaced or recycled only within 100 km? None? Some? What items would be ideal for local production?
