By Russ Grayson, published 7/11/2005Russ Grayson argues small communities need investment and innovation to avoid the impact of declining oil stocks.

Perseus - Just because shale oil wasn't viable at $30 per barrel of oil doesn't mean it suddenly becomes viable at $60 per barrel (or any other price for that matter).
There are a number of fundamental problems with the shale oil extraction processes - both physical limitations (in terms of available water to process the stuff where it is found and the waste disposal problem afterwards) and the fact that the low EROEI makes it a dubious proposition at best anyway. Some background for you to ponder : http://peakenergy.blogspot.com/2005/08/question-of-shale.html http://www.peakoil.ie/newsletters/677 And as another example of someone who is concerned about Peak Oil - Prince Charles gave a speech on the topic a few days ago - its not just lefties and oil industry scaremongers who want people to recognise this issue: http://www.energybulletin.net/10671.html Posted by biggav, Friday, 11 November 2005 6:00:06 PM

I was at that overflowing meeting.
It was packed with every activist and freak you could imagine.
Yes lefty*overs from the 70s, but freshies from the 90s too.
Thanks Big Gav for sanity.
Can some of you in denial like Faustian and Perseus try reading some years of background from the near perfect Energybulletin.net? And Gavs site? Eternal optimism is not a survival trait.
Please also read thermodynamics theory basics, ERoEI principles. (Energy Returned on Energy Invested)
Then try believing this is all going to continue.
As for the internet being sustainable.
Are you kidding?
The power and plastic comes from from somewhere. The embodied energy is awsome.
Please get real.
Or do you need a REALLY reliable source?
Perhaps now Oprah says its a happening thing its a happening thing.?
Yabby should we grow yabbies in retrofitted suburban swimming pools?
Retrofit SUV (suddenly useless vehicles) for portable 100KVA hospital generators, still mobile on the front wheels?
We have lotsa probs to solve quickly.
coping with rapid change is the biggest.
Solar parabolic tracking Stirling to linear electric alternators have currently 2x efficiency of photovoltaics, and ERoEI of 30+.
Oil has ERoEI of 8 and falling. was 40.
Tar sands and shale are at 1.5....Barely marginal
a 5 metre dish could supply the current greedy lifestyle energy to which we seem addicted. Trouble is it would be local. not greed*grid distributed, and cost about the same as a new SUV...
LOL
teraniafossil.
PS 1kw of sunlight falls per sq.metre
0.71% of this drives wind waves and currents...viz all other sustainables
0.023% is photosynthesised into high energy organic molecules. Piddling.
The energy in 24 hours of sunlight exceeds all the energy in all the oil past and future. Awsome. Our 900mm dish boils a coffee in 180 seconds. Theoretical is 144s, were working on it.
