Yes. If you look at oil prices over time you see that oil prices go up, and go down. They always have and they will continue to do so. Now that oil prices are high, investment in increasing oil production are at record levels. Meanwhile, since oil prices are high, investment in energy conservation and alternative energy sources are also at record levels. The combined effect will be increased supply, decreased demand, and decreased oil prices. Some experts predict that oil prices will drop to 1999 (the all time low) levels by 2010.
