WE DON'T HAVE A LIMITED AMOUNT OF OIL, if OPEC, ext, and the us government really wanted to, they could make oil $25 a barrel, how? opec and the greater 13 states control the amount of oil that can be pumped out of the grown per day, cause they truly don't know how much they have, but in order too keep the demand lower the then supples they higher the gas prices, they have the ability to make bill gates ride a bus to hummers are really cool, but peek oil was made in the 50s so the oil in Canada, Russia, and tons of other places have not been in this system.
