forums energies: society, ecology and clean technologies

well known to insiders, but interesting!

one of the speakers said that a new car used between 27 and 54 barrels of oil for its production.

One barrel is 150L

We therefore estimate the "hydrocarbon equivalent" of a new car at 4050 to 8100 L

Take a median value: 6000 L, and 6L / 100 km

The gray energy of a new car is equivalent to traveling 100 km ...

After that, there will always be fine spirits explaining that you must quickly change your "old" vehicle for one that "pollutes" less because it consumes 0.5L / 100 km less ...

Yes Remundi, that was the order of magnitude that we estimated a long time ago here.

At the time we started on the difference in consumption changing cars (2 or 3L / 100 gain) ... and it seems to me that we had fallen between 150 and 180 km. Which is the same order of magnitude of these figures.

After all, it depends on which car we are talking about: an American is probably less optimized for manufacturing than a Japanese.

Uh, the barrels you are talking about are "pure petroleum energy" or "petroleum energy and manufacturing process" (plastics, tires ...)?

I did not watch the documentary in full ...

I think the guy is talking about released thermal energy, brought back in liters of oil.

It’s at the beginning of the report, just after the vintage advertisement on Ford models (around 4 minutes)
