I saw this article about the cost of high oil:
I totally agree with the author of this article. As oil increases in price, there will be more and more resources spent in developing more oil resources. Eventually there will be an over abundance of oil and price will need to fall. The problem is that we need to survive this oil shock long enough for the new sources of oil to emerge.
We will see what happens. If I had the money, I would purchase a CNG car, or purchase a CNG conversion kit for my van. I'm still thinking about the CNG conversion kit for my van. If I can fill up my van for $25 instead of $100, I'm all over that. And it probably would not take too long to pay for itself. However, we need to get the car and van paid off before we can do that.
