That's what the origional poster was saying. See there are 3 peaks that we care about. The first is Peak American Supply, the next is Peak Traditional Worldwide supply, and the third is Peak worldwide non traditional supply. I think he was implying that the transition to shale is an indication that we are moving to unconventional sources, thus indicating we've peaked on traditional sources.
