2) Intensive urban agriculture and solar energy development even if they are not economically feasible to increase our self-sufficiency and resilience to energy and food supply disruptions.
3) A Steady State Economy (see Links 1, 2, 3, 4): "An economy viewed as a subsystem in dynamic equilibrium with the parent ecosystem / biosphere that sustains it. Quantitative growth is replaced with qualitative development or improvement as the basic goal." The growth-centric economy is no longer sustainable with dwindling supplies of fossil fuels.
"The economists all think that if you show up at the cashier's cage with enough currency, God will put more oil in ground." -- Kenneth Deffeyes
"There is a huge body of evidence that the next energy transition will not follow the pattern of recent centuries to more concentrated and powerful sources. The likelihood that this transition will be to one of less energy is such an anathema to the psycho-social foundations and power elites of modern societies that it is constantly misinterpreted, ignored, covered up or derided." -- David Holmgren
"The [energy] surplus has led us to believe in the possibility of universal peace and universal comfort, for a global population of 6 billion, or 9 or 10. If kindness and comfort are, as I suspect, the results of an energy surplus, then, as the supply contracts, we could be expected to start fighting once again like cats in a sack. In the presence of entropy, virtue might be impossible." -- George Monbiot
"The same thing happens in state affairs, by foreseeing [problems] at a distance, which is only done by men of talents: the evils which might arise from them are soon cured; but when, from want of foresight, they are suffered to increase to such a height that they are perceptible to every one, there is no longer any remedy" -- Niccolò Machiavelli, The Prince "We are today living at the end of the period of greatest material abundance in human history - an abundance based on temporary sources of cheap energy that made all else possible. Now that the most important of those sources are entering their inevitable sunset phase, we are at the beginning of a period of overall societal contraction.
Once we accept that energy, fresh water, and food will become less freely available over the next decades, it is hard to escape the conclusion that while the 20th century saw the greatest and most rapid expansion of the scale, scope, and complexity of human societies in history, the 21st will see contraction and simplification. The only real question is whether societies will contract and simplify intelligently or in an uncontrolled, chaotic fashion."-- Richard Heinberg, Peak Everything
