Community is not something you have, like pizza. Now is it something you can buy. It's a living organism based on a web of interdependencies- which is to say, a local economy. It expresses itself physically as connectedness, as buildings actively relating to each other, and to whatever public space exists, be it the street, or the courthouse or the village green.

There is not going to be a "hydrogen economy," and no combination of alternative energy systems or fuels will allow us to continue the suburban pattern. It's finished. We will, however, desperately need to grow more of our food closer to home, and so the preservation of agricultural hinterlands is of great importance. But don't expect the fiesta of suburban construction to continue more than a few more years.

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 the insidious cartoon of the country house in a cartoon of the country.

The "Green" community, the enviro people, are preoccupied with running all the cars differently. Our techno-grandiosity has us gibbering about high-speed rail - which we don't have the capital for anymore - but nobody is interested in repairing the existing rail system, which would be far less costly and hugely beneficial for us. In short, we are acting cluelessly. And life is tragic. The clueless usually suffer.

The fortunate and successful New Urbanists will be the ones who can find local infill projects in small towns and small cities associated with farming, water transport, (perhaps rail too) and water power. I do not believe personally that we will retrofit much of suburbia in the way many people wish we might. The capital won't be there, and I'm rather convinced that the population is headed down - though this will be a lagging effect, because even starving people have sex.

If it happens that the human race doesn't make it, then the fact that we were here once will not be altered, that once upon a time we peopled this astonishing blue planet, and wondered intelligently at everything about it and the other things who lived here with us on it, and that we celebrated the beauty of it in music and art, architecture, literature, and dance, and that there were times when we approached something godlike in our abilities and aspirations. We emerged out of depthless mystery, and back into mystery we returned,and in the end the mystery is all there is.
