decades under both GOP and Dem administrations...from the attached EIA link...
"EIA is the nation's premier source of energy information and, by law, its data, analyses, and forecasts are independent of approval by any other officer or employee of the U.S. government."...i.e. it is a completely independent and non-political agency.
btw, I'd like to see your sources that supposedly counter the EIA's finding of ~5 years remaining for Proven Oil Reserves without imported oil.
