better over water as well ;-)

And the road network uses lots of energy for street lighting, and other
secondary consumers such as hospitals, insurance offices, police, and
all the other apparatus that supports car use in Britain, but which
isn't directly paid for by the motorist and isn't counted in the cost
or energy per mile.

Airliners also have quite high support requirements: airports, air
traffic control, etc.

Trains are probably best, as a lot of railway stations are pretty basic.

You're telling me.


There's a secondary environmental benefit too in that railway lines are
often corridors for wildlife.

So are the trains.
