If you take for every country  its oil consumption per capita, per GDP, per area (say, in square metres) and add some coefficient connected with climatic zone (say a 10.0 for the countries with the most favourable weather which will include the bulk of Central/Western Europe and put a 1.0 for the country with the worst climate - Russia and put the rest of world in between)
...er... and why do i want to multiply all this, not that i know anything about non-linear stuff... ah well, then you will get figures which may show another picture (very simplistic but anyway) of the worst natural resource wasters in the world

I am even not sure that the US will be the number one offenders
