Read an article about that today cuc, something about people investing more in commodities like oil and less in the dollar. Thus increasing the value and price.
Oil shortage isn't something we will come across in our lifetime. There are plenty of untapped oil sources around the world. I live in Indiana and there is a huge oil deposit that runs below southern Indiana and Illinois and it isn't hardly being tapped at all. Granted you can say that price will go up as new sources of oil need to be tapped and prepared but that wouldn't be a drastic cost.
The Middle Eastern countries that we are friendly with and OPEC are more or less cranking up crude oil prices because they know that in the future cleaner more readily available energy sources will become the headliners for energy, leaving them with **** for an economy. This is also why some of these countries are creating grossly huge and expensive resorts, to prepare for that eventuality.
Blame can also be placed on oil companies on the home front, as when they report record profits, it means they are making that much more money off of the average consumer than they did the year previous, regardless of the price of crude. Profit takes into account costs.
Oil prices won't triple in the next three years again, I doubt the economy could support it, then again I remember farmers talking about going under when gas hit 2.50 a gallon in the US. They didn't. But it's safe to say we won't see gas cheap anymore.
Blame the suppliers.
