It has struck me that buses are excessively large - I expect a
significant part of this is due to the fuel they are carrying. Not
having to transport fuel to the depot and the reduction in noise would
make electric buses more attractive so, I expect the spec and the
infrastructure would be different for electric buses - perhaps powered
by batteries charged by wind power.
