@r101958,
1) GDP numbers typically take into account inflation. In other words, that 38% rise over 10 years was a
real 38% rise, after adjusting for inflation.
2) The numbers are in constant euros. Yes I think they changed over to the euro somewhere in the late 1990's, but prior to that they just converted the old German marks to the value they assigned it to the new euro.
3) Yes of course infrastructure plays a role. Nevertheless, it still shows that an economy can grow without consuming more oil.
If you don't trust the example of Germany due to the euro-mark issue, then look at Japan, which has had the same currency for a very long time. Between 1996 and 2006, oil consumption in Japan actually
declined.
Yet, between the first quarter of 1996, and the first quarter of 2006, Japan's economy grew from 118,018.90 billion yen to 134,960.60 billion yen, a rise of 14% (

real" - "real," meaning of course, that they've adjusted for inflation.
