Petrol pumps also have insanely high energy requirements and take a long time to permit and build. And for good reason. They just get their energy via tanker.

The fact that something needs energy doesn't mean we shouldn't build it.

You keep talking about diesel generators. So what if these chargers have diesel generators for backup. People in EVs are probably ok with a fall back to diesel generators - they probably all used to drive petrol cars. It's not this smoking gun you think it is.

The point is that we are moving from oil to not-oil and EVs make this a reality even if occasionally they fall back to the way things are done at the moment (i.e. using oil)
