Imagine you are an exxonmob or peabody boardroomate.  From that POV it would make sense to keep energy prices on the rise enough to sap the political and financial will from your enemies.

But not boost energy prices quickly enough to make alternative energy sources cost competitive.

It's easier to understand the diversion strategery of "clean" coal and "clean" gas guzzling in this light.  They want their earnings to increase every quarter, forever.

Beat the competition and that is possible?  Beat them anyway you can.  "Winning is not the main thing in life, it is the only thing."  

If renewable energy and conservation actually reduce energy prices?  It's 66 cents per gallon to replace gasoline/ethanol with electricity in a plugin hybrid, and wind power is surpassing every other source in terms of low cost grid power.

Maybe then the ever rising price strategery would backfire on the old energy economy barons.  Low cost distributed power to counter their oil wars and MTR and tar sand cookery.  Solar panels on your roof charging your plugin vehicle, hybrid car or bikes.  Or powering electric mass transit through the grid.
