The thing about 9/11 is that for most people the topic loses interest logically-you either accept the evidence that factions in the USA government were possibly/probably involved, or you don't. If you accept the evidence, now what? Unlike oil depletion, insights gained into 9/11 cannot really be used to advance your life, so naturally people leave it alone.

Another group besides the Libertarian is the Coast-to-Coast/Art Bell crowd. They seem to be interested in whatever has a conspiratorial bent to it. The problem is that with Peak Oil, there is historically very little by the way of conspiracies associated with it. Perhaps the "oil industry collusion" or guvmint cover-up will grow in stature, and these guys will get all confused and not know which side to believe. It's possible that the C2C crowd will swing from believing in Peak Oil to believing in a Peak Oil conspiracy.

'conspiracies' in oil/energy I can think of tight off the top of my head.

Teapot Dome scandal
The price fixing conviction in propane in the past few years
Enron
Standard oil

That list is as fast as I can type. With digging, I'm sure more could be found.

I meant with "Peak Oil" not with regular corporate shenanigans.

An example would be that the government is hiding the fact that there are vast quantities of abiotic oil available that is off limits because it would anger the Martians who are secretly siphoning it off.

Ahhh, but this is where the two parties talk past each other. Alex and others like him can point to corporate historical 'shenanigans' and raise the question - "Is it happening again?" What they can see is actions that do not match past claims, money being transfered at record rates, and "oilmen" in charge of the nation. Any data that does not support their believe is deemed 'a lie' or what 'a useful idiot' has to say.

An example

An actual example would be nice. Of the ones who get air time, William Deagle has the Linsey insider (common to others) and claims the alien tech that he knows of will save us.

I guess this is the triangle of talk show politics. We have progressive politics, conservative politics, and the marginalized libertarian/conspiracy politics. I hear things about the latter, Alex Jones and such, but don't pay excessive attention to it.
