I bought a book called “The last oil shock” It’s 250 pages of pure horror! I know that when someone writes a book, you have to take what they say with a pinch of salt… But for some reason what this guy is saying makes sense…. I’ve been getting weird dream because of reading this book. Should a fraction of the facts that he as stated come to pass, it will spell disaster for mostly everyone on this planet.. World recession, More wars, less food available.. And all this takes is for us to run out of cheap energy….
Oil is due to peak, that is 50% of the proven reserves are gone and production will start to fall.. at and average 3% per year.. as this happens the price of oil per barrel will rise from what it is now $70 to a predicted price of about $400 per barrel.. It’s not a matter of if this will happen but just how fast. On average 84.9 million barrels of oil are used per day and finding alternatives to this is a mind blowing effort.
The life of excess is over, produce arriving from all over the world will stop(it will be too expensive), Growing local will be the normal maybe even in your garden 
as funny as that sounds… Some people will says “Fuck it! let the party contine”. For me I think I will double my effort to try and use less energy… Consider MPG of a US car to European car.. 24.5mpg for a US car compaired to 40+ for a European… if the US double their MPG they would half their oil consumption…but this would only delay the oil peak and eventually no matter now fuel efficent US/European car get we are still using a finite resource…
I personally think that no one technology will replace oil for use as cheap energy. Hydrogen, biofuel, nuclear, wind, solar will all have their place… I do think its not about finding a replacement for oil but about living within this planets means for providing energy, For this to happen we have to do with less………….
