Usually using electricity in something like an electric car requires more emissions to generate the power than would be emitted from the food and respiration required to walk the same distance.
Bicycles are interesting because they improve efficiency so much that it offsets the emissions needed to make the bike, and e-bikes are able to leverage that high efficiency to get 80+ km of travel per KWh (compared to ~6 from something like a Tesla)
E-bikes sit in a weird spot where the amount of human effort saved is substantially higher than the carbon footprint of the components.
Which implies the optimal transportation mix would be electric trains+trams with e-bikes to go the last few miles.
Can you elaborate on the first bit? It’s counter intuitive, considering electricity needs to be produced somehow, so I’d love to learn the background.
