I remember 20 or so years a go the rush to build refineries overseas and save Americas environment.
The oil companies liked the idea because building refineries overseas saved them taxes and they didn't have to comply with every requirement by every loony environmentalists.
It takes about 7 years just to get approval to upgrade and expand our current refineries and God forbid building a new one that is more energy efficient.
the major oil companies don't want to build anything, they like the situation just the way it is. tight refining capacity, lack of storage for refined products, high prices and high profits. why would they invest to change a system from which they are reaping record profits?
