There are three main reasons for the continuos rise of oil prices, mainly in America:

-some speculators wishing to make a wonderful proffit

-the weak U.S. dollar

-the growing world demand

All these reasons are involved most probably in the oil price rise, and solving only one of these is not enough for the global crisis.

It started to seem, that the oil price will rise slow, but sure, on a daily basis for an  eternity. But suddenly, the price for an oil barrel dropped by 16 $ from tuesday, 14.07 to thursday, 16.07. The economists point for that the weaknesses of the american economy and the inflation (words; we simply feel to pay more).

As a consequence, other prices will follow. And the client will not buy anymore unnecessary things, putting the economy in collapse!

All these matters shall have two positive results:

-the growing of the environment awareness

-stimulation of researches by the car makers

The bad things have sometimes positive consequences.
