Europe is third since the 2000s. The pushed the Euro to try to limit it (and from the mouth of someone who was present when they pushed, it was also caused by the black Wednesday of 92, the attacks on currencies increased, and the cost to rebuff them too).

And yes, basically, no one should include europe in the comparison until US oil fields are depleted, and even then at best it would be a race for the second place. You can't compete without gas and oil or a huge manufacturing lead, and europe don't have any, and only have specific subset of manufacturing (basically sensors, electronics, avionics, optics, and handmade clothing) that isn't workforce-intensive, nor resource-intensive.
