Again:
Oil will always be the life blood of the WORLD.
Don't believe you can make plastic from the SUN, WIND, TIDE, and GEOTHERMAL. Although Gore, Soros, and others would like you to believe.
As a professional scientist for 10 years, discoveries point to oil as regenerative. Meaning that environmental and chemistry conditions keep the stuff coming, in other words, not a finite source if utilized properly with no GLUT.
Also, it looks like Oil has become the currency base. I believe oil will stabilize at $75 and the support is $40. Oil at less than $60 only shows the producers that they can't have financial dominion over the WORLD. The Global Financiers still, and always will, RULE.
