If you think the oil companies have a bird nest on the ground, then you should invest in an oil well. There is a good chance you will lose all your money, a better chance you will break even, and a small chance you will make a lot of money. These are the risks the oil companies take, and there is a finite amount of production available for them to sell. If I was them I would get all I can get before it runs out.
I don't understand why some people think that certain commodities are owed to them at a price they think its worth. Free enterprise doesn't work that way. Nobody is holding a gun to your head to buy their product. Buy a fuel efficient vehicle or get a bicycle if you don't like it.
The market will determine when an alternative fuel source will be economically feasible. Right now, oil is the cheapest source.
