I think we will have the will to transform ourselves into a much greener nation within 10 years. I don't think drilling up our beaches for a tiny price break in 10 years is the solution though. The solution is electric cars and massive tax breaks for installing solar panels or a wind turbine on your home. That eliminates the pollution caused by the plants that provide homes electricity and gets rid of a huge amount of the oil dependence in our transportation sector.
We can do lots besides those two things, and we should, but just those two alone would probably get us off of foreign oil. But all oil, foreign or not, comes from the oil companies for the best price they can get on the global market. So ending dependence on foreign oil doesn't mean we'll ever again have anything resembling *cheap* oil. If China will pay $300/barrel, and we won't, China will get the oil. A bidding war. We'd best be waaaay less dependent on oil, domestic or foreign, before we reach that stage. Drilling up our beaches will only make people think that things are gonna be fine now. But that's a dangerous illusion to feed people. Whenever we perform the transformation we need it's going to be painful, but the sooner it's done the less pain we will feel.
The reason gas prices are dropping is because the prices went too high and there was enough demand destruction worldwide to make a difference. I'm sure there were some psychological effects on the market too, but the best cure for high gas prices is high gas prices, and we just watched that happen.
