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.

I believe we are deluded about alternative energy. The key is, whatever we do, we're going to have to do on a very modest scale. It's all about scale. We're not going to build giant wind farms with Godzilla-sized turbines all over the place. That's a fantasy.

The task we face is reorganizing the systems we depend on for daily life in a way that is consistent with the realities coming down at us.

Government at all levels in the USA right now is engaged in a quixotic campaign to sustain the unsustainable. We're determined to run WalMart, Disney World, the Interstate Highways, suburbia, and an imperial military by other means than oil. We'll squander a lot of dwindling resources in the process.

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.

The suburban cycle which began a hundred years ago is nearly over. We are in for a period of contraction and economic hardship.

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.
