On top of the insult of destroying the geographic places we call home, the chain stores also destroyed people's place in the order of daily life, including the duties, responsibilities, obligations, and ceremonies that prompt citizens to care for each other.

The skyscraper - any building over seven stories really - will come to be seen as an experimental building type that doesn't work well in an energy-starved economy.

We don't need gold plated highways. We don't need zoning commissions which penalize offices at home and promote car commutes.

The economy of the 21st century will come to center on agriculture. Life will be intensely and profoundly local in ways that we can't conceive of today. Economic growth, as we have known it in a cheap energy industrial paradigm, will cease.

Suburbia is not going to run on biodiesel. The easy-motoring tourist industry is not going to run on biodiesel, wind power and solar fuel.

We could do some household and neighborhood or town wind energy. But even this will run up eventually against the problem of needing an underlying fossil fuel economy to fabricate the hardware. Same with photovoltaic (solar) energy. We're going to be disappointed by what these things can do for us.

I think water transport will see a revival. However, we're not going to replay the 20th century. The industrial city of that era will not be revived. Our cities are going to contract. Many of them will contract as a whole but densify at their core.
