We've got 21st century technology and speed colliding head-on with 20th and 19th century institutions, rules and cultures.

Many analysts now regard modest, zero, or negative growth in our rate of energy use as a realistic long-term goal.

Economies are supposed to serve human ends.. not the other way round. We forget at our peril that markets make a good servant, a bad master and a worse religion.

Rely on renewable energy flows that are always there whether we use them or not, such as, sun, wind and vegetation: on energy income, not depletable energy capital.

Fire made us human, fossil fuels made us modern, but now we need a new fire that makes us safe, secure, healthy and durable.

If you ask me, it'd be a little short of disastrous for us to discover a source of clean, cheap, abundant energy because of what we would do with it. We ought to be looking for energy sources that are adequate for our needs, but that won't give us the excesses of concentrated energy with which we could do mischief to the earth or to each other.

In the model that we grew up with, governments rule physical territory in which national economies function, and strong economies support hegemonic military power. In the new model, already emerging under our noses, economic decisions don't pay much attention to national sovereignty in a world where more than half of the one hundred or two hundred largest economic entities are not countries but companies.
