I found no direct comparison but by using the two references below I was able to make an approximate comparison. The first reference gives the economic energy intensity of several countries. This is the amount of energy required to produce each dollar of GDP (Gross Domestic Product) for the year 2004. The second reference gives the per capita GDP by country for the year 2006. Unfortunately these two years are different but if we make the presumption that the numbers are fairly close given only a two year difference then we can calculate the per capita energy consumption and it is:

USA = 433 GJ/person

Canada = 374 GJ/person

Thus in this period the US per capita energy consumption was about 16% greater than Canada.

Try wikipedia? They may be of help. I Bet the answer is the ENERGY HUNGRY AMERICANS!
