We already peaked in oil in most places around the world. The US was the world's #1 oil producer for 100 years, I believe until we peaked in Dec. 1970 (look up Hubbert's Law)
We aren't finding ANY new large sources of oil - haven't discovered any in years, even though the world as a whole has ramped up disovery efforts.
The essential problem is that the 6.4B people on the planet are eating oil. Without oil, we never would have reached more than 2B people. The only reason we can feed that many people is simply, oil. Period.
Petrochemicals are used in fertilizer and pesticide - and the reason we have wide scale agriculture.
If oil is replenishing somehow, why haven't we made any new discoveries? Why are all countries that we have data for in decline? Why is Saudi Arabia pumping massive amounts of salt water into the ground to get more oil?
At current consumption rates with the growth of Chindya, my understanding is that we need a new Saudi Arabia every 3 years.
Demand has or will outstrip supply VERY soon and I think that's why we've begun this endless cycle of resource wars.
There are countless books on the subject, find them on amazon or at any B&N - most are in the "nature" section (some are under economics). Read Kunstler's "The Long Emergency" for a primer.
Personally, I don't welcome Peak Oil. That means the beginning of the end of most of what we know. It ultimately means that we'll probably lose 2/3 of our population.
I've read up on all the alternatives - and once you do, you'll understand that all combined, they won't have much of an effect. Uranium and Coal are good short term solutions however those are finite as well. We've reached Peak Natural Gas in the US as well.
Maybe if we had started working on this problem in the 70's and began conservation efforts and efforts to control the population, something could have been done.
Still, I'm an optimistic person and will do whatever I can to make it through this difficult time. I am not scared or worried in the least. I'm not even "down" about it. Reality is reality, and you have to just do the best you can.
I totally understand the desire to continue to believe that a solution is at hand - that technology will save us.
I could put up a bunch of graphs and links, but all you need is below. I have several Peak Oil DVD documentaries and would be glad to mail you a copy if you PM me.
