In your diatribe againgst the big, bad "export-oligopoly" it is curious you never mention the international oil companies. Certainly they have some power/agency?

Also, the Saudis could care less if we all installed PV electricity/heating systems. Everyone knows the crux of oil demand is in the tranposrt sector.

PHV stands for plug in hybrid vehicles. The private big oil companies control extremely little oil themselves - not that they are innocents in the woods, of course.
