Bearing in mind that Europe's public transit infrastructure alone can account for a lot of that difference. Low population density begets higher personal vehicle dependency, and a higher chance of an oil-heated home as well.
What infrastructure there is often is just maintained enough to say it exists.
Put it this way: when I was a student in London, Ontario and took the 200km train ride home to Toronto, it was the norm for the train to arrive around the time it was supposed to be reaching its destination. The (diesel) train couldn't go more than 100km/h, because a lot of the track it was running on was so old. The trip, once the train showed up, took about as long as it did in the late 19th century.
Yeah, I know the trains are late and slow in Europe too. But not like that.
