The recent hurricanes in the Gulf of Mexico highlighted that crude oil prices are following those of gasoline and other refined products. Given our analysis that shows global refining capacity only increasing by 4.3 million bpd (5%) by 2010, we expect this pattern to continue in the coming years, supporting high prices.

To make bio-diesel from vegetable oil, you get the oil from the restaurant, heat it up to about 120°, mix it with methanol, and lye, the right proportions, shake it, let it settle, and you get glycerin at the bottom and the rest is all bio-diesel ready to go.

Although some member countries have signaled an interest in reducing the cartel's production output target of 28 million b/d due to concerns of oversupply, a reduction is unlikely, in our view, given the current high crude oil prices, which have gained $5/bbl this year primarily as a result of a geopolitical risk in Iran and Nigeria.
