Ever notice, through the years, that whenever these predictions are made the "peak" is always seems to be a few years out.
The United States' "Past the peak 1970" is probably when the EPA and individual States started cutting back or stopping production. I am not certain, but thats a guess.

The world peak of easy oil is not more than ten years off.
