I don't know if it really proves anything and it might be OT from your point, but, the confounding variable is that in the US - especially outside of the major urban areas - everything is just very far away in terms of miles. Lacking a car, you can expect life to be very difficult. there are still plenty of places in the US where the range of a tesla might be a borderline problem week-to-week. (though probably not as…

I think it is well known the car and petrol companies were heavy lobbyists in developing the transit architecture in the US (including zoning and so on) after the second world war. To exaggerate a bit, the entire country was designed to facilitate automobile sales. https://en.m.wikipedia.org/wiki/Effects_of_the_car_on_societ... In the continental europe most of the urban centers predate the automobile hundreds if not…

While electric buses are almost certainly an emissions win compared to the no doubt primitive and dirty Chinese diesel buses, I doubt it is it fair to call them zero-emission? China burns a lot of coal for electrical power.

That is picking nits :-) Not only is China rapidly building nuclear power plants, containing the emissions of one plant burning coal is easier than containing the emissions of the 10,000 buses that plant provides power to operate. There is also a benefit to China converting from oil (something imported[1]) to coal (something available locally[2]). [1] https://oilprice.com/Energy/Crude-Oil/Chinas-Becomes-Worlds-... [2…

how do you contain CO2? its a gas so very voluminous, do you propose liquefying it and keep it refrigerated?

One interesting feature of articles like this that I don't really get is that they often leave out a huge huge quality of life benefit that electric vehicles bring: reduced urban machine noise.

don't worry about the noise. At least here in France we've got you covered with scooters all over the place, including the heart of town! these things seem to be mostly unregulated since the 80s or so when it comes to noise and "stinky" emissions... :|

Obviously the US has some structural issues, otherwise it wouldn't have these persistent failures. All I'm doing is pushing back against the simplistic "but the US is so big compared to all those tiny countries". If you want to talk about density or uniform distribution... Why is Australian public transit so much better than American public transit? America's governmental structure isn't unique either. There are othe…

> Why is Australian public transit so much better than American public transit? I would guess it's because Australia is, like, 99% uninhabited and uninhabitable or borderline uninhabitable[1], which probably means they can focus resources almost exclusively on the few densely populated areas. Additionally Australia's urban population seems to be significantly higher than America's (~89% vs ~80% according to 5 seconds…

Cyclist here in Tokyo with hybrid buses. The hybrid buses start from stop on purely electric power. The diesel engine seems to kick in at speeds above 10kph. Compared to the large amount of exhaust belched out of diesel only, as cyclist sometime stuck behind a bus, the electric start is a big relief.

Can't wait until Japan adopts the same all electric design.

Even hybrid busses help a lot, and as a passenger it’s lot more comfortable to not feel the engine vibrating the whole bus when you are stopped in traffic. It seems that all the newer busses in London are hybrid or electric now, which seems like an easier target to reach than going full electric.

Here in Germany with have quite a few hydrogen powered buses.

Examples:

But also elsewhere in Europe (here: South Tyrol, Italy): http://www.greenmobility.bz.it/en/projekte/die-bozner-wasser...

Nothing but water vapor coming out of them.

"they consume 30 times more fuel than average sized cars". Is that true? That seems gigantic, I thought taking so bus was so much better for the planet than taking your car.

Bus weighs ~30,000 pounds. Car, ~4,000. So I would question this stat.

At full capacity, a bus would be able to pack more people, in a much smaller space than a full capacity car, so there's your savings in fuel.

Plus I would assume that one, larger engine in a bus is more efficient than ~10 smaller engines. There's also the hidden cost of manufacturing a bus - does one bus take less resources to manufacture than the cars it may be able to replace?

According to,

https://en.wikipedia.org/wiki/Energy_efficiency_in_transport...

"A commuter service in Santa Barbara, California, USA, found average diesel bus efficiency of 6.0 mpg‑US (39 L/100 km; 7.2 mpg‑imp) (using MCI 102DL3 buses). With all 55 seats filled this equates to 330 passenger mpg; with 70% filled, 231 passenger mpg.[51]"
