World Oil Reserves and Oil Consumption, 1980 to Present
Notes: 
1. Canadian tar sands were included in 2003.
2. The polynomial curve fits better than the straight line.
3. There are significant finanical incentives for companies to over estimate oil reserves.
4. The USA consumed 20.7 million barrels of oil per day, or 7.56 billion barrels per year in 2004.
      Thus, the USA consumed (7.56/30.147)*100 = 25% of total world oil used in 2004.
5. DOE, EIA data online as of 3/30/12.
