Hi all , my interest is on energy input in human society
Roughly speaking we went off sustainability around the start of the 18th century
This as been good , with great progress in knowledge and comfort
the world population has grown from about half a billion to 7.5 billions and rising fast ,
the standard of living has grown for the top fraction from 90% food budget to 15% food budget ,
the rest being personal spending and taxes
This was the energy consumtion up- slope
there is a large consensus that oil extraction is peaking about now , the exact date will probably be be argued for ever ,
gas peak is not too far off either
I was shocked to see the projections for peak coal , instead of centuries , it might only be decades
U 235 is not over abundant either , at current usage less than a generation
That's 85% of the energies sources going into decline of a few percent a year for the foreseable future ,
let's call it the coming century
a few percent decrease every year is a severe economic depression every year , years after years in an relentless manner
the growth in reverse , the energy down-slope
I would suppose the price of food to sharply increase , leading to less personal spending , the services and consumers sectors would be hit leading to a lot of unemployment , less government revenues with more public spending
This would be for the first years ,
the recessions would continue ,
The worst off , as countries or social classes would soon enought face the Lassale minimum , working to get enought food to stay alive to work another day ,
The recessions would continue ,
eventually , things would find a new balance , let said at the billion population mark , with 90% of the population living on the land and a couple of cities of around one million inhabitants
The surviving groups would be the most backwards , they had less to adapt and probably the more ruthless too,
Could you shoot holes in this scenario , I REALLY could do with some cheering now

1. There are energy alternatives - both nuclear and renewables. See here:
http://europe.theoildrum.com/node/2661 Solar and wind have EROEI of 10 plus and the technological challenges regarding intermittences are being worked out. See here:
http://www.theoildrum.com/node/2749 Europe will have 20% of its electricity coming from renewables by 2020. Advocates say we could get 100% of our needs from renewables if we decide to fully get behind them.
2. The view that we can't go nuclear appears to be wrong. There are huge quantities of Uranium and there are also breeder reactors and thorium. Remember Hubbert was a big advocate of Nuclear. He saw it as replacing fossil fuels.

3. Gas and coal will be around for a while also, with peaks in circa 2030 and 2060 respectively. However there is a huge amount of stranded gas that could become viable in a high energy cost world. So that peak could be pushed out.
While there will be severe economic problems and the standard of living of many people will fall, there are alternative sources of energy to build a sustainable system. I don't think this is the end of high energy man but many of our current practices will change.
Peak oil is not an 'energy' problem but it's a liquid fuel problem. In that regard we have a real problem. The only solution is the electrification of our transport system. The US with their stupid SUV's and the urban sprawl will be very badly hit.
I actually welcome peak oil as an opportunity to compel us to build a truly sustainable carbon-neutral energy system. I hope we are able to go one step further also and stop waste of all kinds and effectively recycle everything. In addition to this, peak oil will show us we have limits to our existence and can’t go on with massive population growth and exponential growth. Unfortunately the places where population is growing rapidly will be hardest hit with famine and there will be little we can do about it. Again, hopefully this will force the third world countries to get a handle on population growth. It will also mean the end of globalization and therefore the end of the rise of China, which can only be a good thing given their current autocratic political system.
One final point is while most people lives will get a lot worse, if you make the right investment decisions before peak is truly realized by the public and financial markets, you could increase your relative wealth many times over. For example, buy gold and silver coins and certificates, oil&gas majors and service stocks, uranium mining stocks, nuclear companies, renewable companies, agricultural land, inflation linked government bonds and many more possibilities – if you can get your pension money out of the pension company do it right now and self invest it.
