What the Iranians know is that the green gasoline juggernaut has already been launched. It is projected to be competitive at $45 US, and recent breakthroughs, both from simplified production and the ability to use existing infrastructure, should see the cost reduced further. And once production increases, carbon taxes will be used to cut the fossil oil margin further. In the longer term (10 to 20 years) there is the prospect of cheap solar energy being the spur for an electric car industry.
Oil will probably rise further in price. It's the last party for OPEC imo.
