> Biofuels probably wouldn’t look like as much of an outlier as they do here, but I would still wager that they’re among the least efficient options. I wouldn't wager because it's not a simple yes or no type question. There's a lot of ambiguities even in the analysis behind the graph presented in the article, but when it comes to fuels vs. batteries, it gets even more insane. Fuels have a weight advantage over batteries that gets magnified as the weight and range of the vehicle increases... and there's a lot of variance within fuels too. So, while an electric bicycle is going to be a no-brainer over a motorcycle for pretty much any scenario, it can be quite the opposite for something like a commercial truck. I keep coming back to the economist argument that if we just captured the externalities related to climate change, we avoid having these discussions and simply look at the price of things... but of course, that's the hard part in all these discussions.
