The "Hybrid Cars Blog" suggests that in 2006, the price of gasoline could get ugly. That is, the high gas prices seen in the U.S. last year could be as bad, or worse. See: The price of gasoline could get ugly in 2006
The story seems to be that the cause for last years oil price surge can be found in the gap between China having increasing oil use and weather related outages in oil delivery. This year China's surging oil demand is still there, plus we have several possible outages in oil delivery such as "rebels" in Nigeria attacking oil platforms, and the situation in Iran from which there could be several ways oil delivery could be blocked.
While that story is very true, it is also an example of short term thinking.
In the long term picture the price for oil can only go up. In the short term there will be fluctuations, but long term is a different story. Why? It's because the demand continues to go up in an unabated curve, and the Peak Oil scenario is looming out there.
The Peak Oil scenario is a model developed by oil company scientists that describes production capacity over time. The model shows that the world oil production capability will peak. Already discoveries of new oil fields has dried up with discoveries not at all meeting the growth in demand for oil.
UPDATE in December 2006 ... the price for oil and gasoline did get very high up until September. Then it curiously dropped just before the election, and then has curiously risen a little since the election. Makes one wonder if some kind of price manipulation was being tried by the oil industry to prop up the Republicans? If so, it didn't work.
