I hate to see misinformation being spread.
First off, Diesel Busses Are equally environmental friendly as electric trains. (On long distance trips) this is due to infrastructure emissions, which are far higher for train infrastructure.
Furthermore looking at batteries: Batteries are expensive and very sensible to temperatures. They are virtually unusable in some climate zones. Furthermore a battery burns much hotter than gasoline. Much much hotter. So hot in fact that the damage to roads is immense. In addition to that, battery driven cars and buses are extremely heavy and damaging asphalt infrastructure as well.
The best solution is to shift mobility towards Diesel driven Busses and facilitate car sharing. It’s flexible, mich more flexible than other solutions. This makes it adaptable to many environments and situations. And it does not force people to give up achievements of mobility.
The example in the meme is extra problematic, because steel cables and train infrastructure is heavily reliant on coal. And replacement of coal with hydrogen is not to be seen in the foreseeable future.
Also overhead wires are hideous
Modern OHLE standards are significantly less messy than they were 100 years ago. And if they really are still that bad, conductor rails work almost as well.
Conductors are always connected to energy loss. I don’t mind the cables. They are not looking good, but I can live with them.
OHLE is a conductor too. The issue with conductor rials is that they use DC rather than AC, which means that voltage is lower, meaning substations need to be more frequent. However, the conductor rail takes up no additional space in the loading gauge compared to OHLE, so for underground systems, or systems that need minimal clearance, conductor rails are better.
"Conductors" as in any piece of metal that conducts electricity? Those overhead wires are also conductors, and will see some energy loss over their length like any other conductor.
