Why would that be, except maybe in rare cornercases? You can electrify almost anything, and it'll be more efficient and less polluting.
- bluGill 3y agoThat depends on your ability to get access to electric. While you can imagine wires across the ocean (or at 35000 feet), it doesn't seem practical or cost effective to install them. However if you are in more populated areas odds are you already have electric close and so it is more cost effective to connect to the grid. For transit use, a rule of thumb is if you have a bus every 10 minutes or less then it would be more cost effective in the long run to have wires to the bus (better than diesel or battery buses). However even when you have a bus every 10 minutes odds are you have enough other routes that don't have that frequency and so overall it isn't worth it even though in some places it would be.
