    Good graph, hate the presentation of “X times less”. Just not intuitive and very frequently calculated incorrectly.

    I’d like to see those little city cars added here, those little two seaters that don’t go more than 45kph. Could be a good compromise for lots of people with limited mobility

    What? No, sorry an electric bicycle is not more efficient than a non-electric bicycle. What data fuckery is this?

    Any electrical system is going to loose energy compared to the human body.

    Edit: oh, this should be cross posted to data visualization gore. The more efficient thing is to the right and smaller. But the chart makes it seem like the electric car is the most efficient. Probably they should add red & green colors to make it clear that “electric car big line bad”

    Also “27 time less energy” is like saying “cup half full” and should instead say “27 times more efficient”

      The design of the graph aside, I would really like it to include something for public transit. A train may take 1 kWh to travel 1 Km but if that train is carrying 150 - 450 passengers how much more efficient is it than an electric car? What about a bus, light rail, or subway?

      an electric bicycle is not more efficient than a non-electric bicycle.

      I thought that’s exactly what the graph shows, though?? The way I am reading the graph, the ebike is less efficient per mile – requires more energy per mile – than a non-electric bike, just as you would expect.

    Going to be a data nerd here and point out that even the graph title is incorrect. These bars show energy consumption, not efficiency.

    It’s nice data, but poorly illustrated.

    Pretty fucked up. Do actual energy efficiency (calories burned per km) and you’ll quickly see the bicycle is far above everything

      From a quick search:

      • Cycling = 23kcal / km
      • Tesla: 120kcal / km

      There was an article in cars magazine saying that cyclists were especially polluting. In teir study (in europe), the hypothetical cyclist was only eating Argentine beef lol. So no I do not swallow it.
