Got into a little debate with a representative of the Sierra Club over this particular issue. The subject of his presentation was climate change but he did but up that EIA chart on future production rising to 130 MMbbl/d 20 years down the road. He dismissed peak oil as a non-issue because of subtitutes like ethanol, CTL, GTL, shale, etc. I said coal ain't oil, coal ain't oil, pavement ain't oil, and corn squeezins ain't oil.

You can discuss the following article and presentation next time:

They should shed some light on the issue of alternatives and scaling.
