I actually had some figures around energy impact in earlier drafts of the piece. The issue I kept running into was the range of data - trucking is more inefficient than rail. But the question is how much, it could be as little as 2x more energy or as much as 100x more energy.
It depends on factors like load weight, truck conditions, rail route, and a bunch more.
