It’s difficult to compare Housing/real estate and other commodities with the World energy market.
The biggest driving force is fact that China, India and many formerly third-world countries have greatly industrialized. The World demand for oil has nearly doubled in just a short while.
There is not much of a bubble here at all. Maybe a few dollars as the market fluctuates, but in the long run, it will double again in the near future.
From our own standpoint, we have to import refined distillates because we do not have the capacity to meet our own demand. Now that the rest of the World is starting to pass us economically, we will see even more demand that will sustain the current prices and even drive them higher.
Costs of trading with those countries will also go up because the energy costs went up for those foreign traders.
Believe me, there is no bubble, only foam on the water.
It would appear that speculation may be a bigger contributing factor than you acknowledge.
