With the approach of the 150th anniversary of Canadian petroleum this year (1858-2008), I was reminded of something that has been on my mind for some time. It has to do with Daniel Yergin's best selling book "The Prize". This book is considered to be the most authoritative book on petroleum history. Even though I found this book to be very informative and interesting, I was upset by the fact that so little was written in it regarding Canada's oil. This is upsetting because for many years, Canada has been and is one of the biggest exporters of crude oil to the United States over several other countries whose oil history has been well written about in this book. Thus, Canada's role in supplying oil to the U.S. was largely ignored even though it was important at the time that the book was written. The following chart found on this link shows how Canadian oil exports to the U.S. compare to others: www.eia.doe.gov/emeu/aer/txt/ptb0504.html
