Possibly, if it is obvious to even the most oil-partisan folks that petroleum is in decline, they might be in a position to support "greenhouse gas" legislation to restrict, regulate and tax the hydrocarbon market.  They could blame the need for this on the "environmentalists" but still remain in control as much as possible.

It's not like they are really ignorant of the realities on the ground.  And they will work with "environmentalists" when it suits them -- and the "environmentalists" in turn have shown a willingness to be co-opted.

That is a nice scenario.  Here's hoping.
