These predictions come since as long ago as 30 or 40 years ago (check 'The End of Oil' on Amazon: in 2004 when this book was printed, the 'end of oil' was predicted (once again) to happen... in just few years! Did it?) The thing is every time such prediction is made, new and new oil fields are discovered, technology of oil extraction improved and these folks have to revise their forecast again. Don't be scared:) It's all printed by folks who want to speculate on oil prices.
