The best electric busses have electric lines overhead, so you don't need big batteries.

My city also has been rolling out electric buses the last few years and they ride so much like their gas counterpart that I wouldn't be able to tell which is which without the design/colour scheme they chose to tell you which is which.
We have nearly all electric buses here in Oslo now, and whenever I wind up on a diesel bus I think I'm going to get hearing damage
Electric buses are far from silent, but WOW the amount of noise and stink we've just been tolerating with fossil fuels is insane. Even absent climate change, that'd be worth switching to electric vehicles.
Poznań, Poland has 25 hydrogen buses, and plans to have 9 more by May 2026
What is the source of energy to produce the hydrogen? The carbon footprint of hydrogen is pretty bad unless you have abundent renewable energy.
If it's in Poland, it's most likely coal unfortunately
Well Germany has to sell their shitty lignite coal to somebody..... It's not like their environmental laws will allow them to burn it in Germany. But Poland is fine.....no one cares about the polish greenhouse gasses. That's Poland's problem....right?
or from plastic burning. Poland is where most EU "recycled plastics" end up being incinerated.
To address the trolley bus comments - yes, they are better than battery buses, but my city already has a tram network and the bus network covers too much territory to justify putting trolley cables.
I hate to say it, but trolley cables are ugly, at least where I've seen them. It makes the streets look like old times, when each building or home had a dedicated cable going to it from a pole.
I know it's better than batteries, but is there no other way?
Oh man, but look how much more efficient they are: You have a large, high energy network to draw from when climbing very hard hills and full of passengers.
So the bus electric motor only has to pull itself, the chassis, and the passengers up the hills, instead of all the above plus a several thousand pound battery, whose weight does not vary with state of charge.
My point is, I know you're aware they're better, but they're so much better to where it blasts appearance out of the question for me and others who understand the system.
There is - the electric rail. It can only be used with rail transportation, but allows to transfer power without any overhead cables.
As per buses, the only thing one can imagine is wireless power transfer from under the road, but that comes with an extreme power loss.
Electrified rails are incredibly dangerous for trams as people are expected to walk on the rails while crossing roads, that's why everyone uses pantograph wires
My city is also playing with electric buses buying different brand and models. One Chinese brand they have drives me crazy because it rings a bell as it moves. It's louder and more annoying than the gas buses.
I wish my city was running the electric buses at night. Without the noise of other traffic to help mask it, the gas ones sound like explosions as they drive by at 3a. Unfortunately the bus company said it's cheaper to charge them at night when electricity costs the least.
My only complaint as a user (without considering any of the economics, or environmental impact) is that there has definitely been a bit of an adjustment period for the drivers - I've seen a few standing passengers go flying when the buses accelerate from zero like go-karts.
I am for electrification but I just can't get behind electric buses.
My city made some study last year and the best way forward in terms of public transport is expansion of trolley bus network. With batteries and constant use it just doesn't make much economic sense. If you can build the wiring it is much better in long run. You don't have to have 100% coverage, 70+% is enough for partial battery powered trolley bus, then it starts to be economically feasible in the operating cost sense.
Also they will need to build some kind of metro system - probably as an extension of commuter trains.
Yeah..... We kinda solved this problem in the late 1800's. Overhead electric or powered third rail (depending on need) is really peak public transportation when it comes to cost and efficiency over time.
People always harp on the infrastructure cost when it comes to rail, but turn a complete blind eye on extreme cost of things like road maintenance and need for lane widening caused by everyone driving huge ass half filled busses everywhere.
Road maintenance is one of the largest expenses for most states in the US, and it's largely so much worse than other countries because our dependency on the trucking industry. We're all basically constantly subsidizing the trucking industry at great cost instead of funding adequate public rail.
Toronto has overhead electric trolleys. They got rid of the buses, but only because GM refused to make them. The fleet of overhead electric buses were 50 years old, they never broke.
But I get the appeal of the ebus it just sounds cheaper. One city I won't name started to build trolley bus network again after they got rid of it in 70's (because of metro construction and expansion of trams), but they just doing it bit idiotically by wanting to have like 30% of it on wires and rest run on batteries.
Why? Because the infrastructure is just more expensive upfront.
Will it work? Nobody knows, people that are building it lobby to get it up to at least 50/50 then it is maybe just feasible.
I think that roads and buses have place in the transportation but you just need more options not just that.
I was excited when we started getting electric buses here, then I learnt we used to have trolley buses until the mid 70s. At least we got a tram line in 2021 so that's great
My city was designed in the early 20th century and specifically included space for trams on the roads, but cars took over so trees were planted to fill the space. Now we're building a tramway and many of those trees need to be removed our local green party is in a difficult spot — they do want the tram, they don't want trees removed
So you're saying the better alternative to electric busses is...electric busses
which city?
Boston had newish hybrid deisel trolleys until 2023, when they replaced with battery electric buses.
They claimed the catenary was too expensive to maintain, especially with roadwork. Meanwhile the battery electric buses are completely self-contained, independent, and there are multiple manufacturers.
I’m sure it didn’t help that they were over complicated. This was a new transit line where everyone wanted a subway, but it was too complicated. They needed more capacity than a bus, able to maneuver tight corners, electric to go through tunnels, and unconstrained in traffic. They created Frankenstein monster and called it “bus rapid transit”. Partly dedicated roadway, partly in traffic. Partly above ground, partly below ground. Partly deisel, partly trolley. Bigger than buses but articulated to fit through narrow streets
Understand that I'm from a different viewpoint as a Norwegian, but saw a diesel bus a few months back, and it was a weird blast from the past to see.
Which in general is a more efficient way to use the diesel than if it was in an engine. However I'm not sure in this case, as I don't know how efficient a generator would be compared to how ridiculously efficient a modern engine is. But electric engines outclass anything out there when it comes using energy.
if you rip out an engene from a car, then you can operate it at its most efficient rpm all the time, instead of when you happen to cross the right rpm on the right gear. So an engine powering a generator can almost always be more efficient than in a car.
This is not taking the losses in the electrical system when using the generated power in a moter to make the car move. But in a lot of cases, you still come out ahead
The electrical losses are way less than the resistances of a mechanical drivetrain. It's around 10-25% lower apparently.
The West Australian Electric Car Club had to install a diesel genset part of the way across the country
That diesel was used more efficiently than in a VW golf in km/litre terms because generators are much more efficient than vehicle engines
So has mine! Although the buses in my city are hybrid, not fully electric.
Nice, i really love electric bus, it doesn't stink and it's quiet. My city rolled out some half decade ago, but it doesn't last as the company that made it(Chinese) doesn't support it anymore. Then we got another batch like last year i think. Hopefully this one last.
My city just got it's first electric ferry! Pretty excited to give it a shot.
Edinburgh rolled them out somewhere in 2017 i think? Most of the buses are still diesel powered
jelly... nothing like biking on the wall lane next to the the highway and getting smogged by a gas bus' top exhaust right in your face, right after overexerting to get up there in the first place
Does anyone feel like electric buses are a type of green washing?
I like EVs, but do they make sense for something that needs to be on the road all day? Is replacing a couple hundred diesel buses bringing thousands around a day really what should be getting targeted?
Every little helps and all, but doesn't seem like it should be considered a bug deal.
It's a somewhat low hanging fruit. And every little bit counts
We should not make perfect the enemy of good
They are just better vehicles, both in terms of local pollution, and in terms of propulsion, even if it is green washing.
Yeah, anything that does a lot of city driving and a lot of stop start is much better suited to electric than diesel. At my work - collecting waste - I drive an electric iveco tipper. Only had it a few weeks but already it's so much better than the nasty old diesel I had before.
and noise
As long as they can last all day then charge enough overnight I think they are a big improvement. Air and noise pollution sucks with diesel.
My fear is in extreme cold places, where EVs tend to have issues.
Like a lot of things, this case has multiple sides and is not as simple as calling it green washing.
On one side, a packed diesel buses is far more efficient and probably pollutes less per person than an electric car with a single occupant. So in a way, it's indeed putting efforts on something that's not very high on the list of things that pollute.
On another side, diesel buses are still polluting and the local transit authority here has a multi decade plan to electrify them. It has its own studies, and studies from the nearby universities, showing that electric buses can be attractive and effective for different types of routes, and less for others. They are replacing the buses according to this plan and it's nothing to be against. I don't consider this green washing, coming from a transit society, but it's an easy target.
But yeah, electric buses from your transit society is a nice plus. However diesel buses are also just fine, and even desirable, if you use them as an alternative to driving and to reduce pollution from car traffic.
This reminds me of an old meme that I kept.

I'm not sure I follow your logic. The environmental impacts of manufacturing will be averaged out faster with something that's getting a lot of use, and targeting the efficiency of something that gets continuous use has more impact.
Throwing away busses to switch would be silly, but it's a perfectly good idea to switch as you maintain your fleet. Your alternative is buying more diesel busses, which... No, building a trolley or tram system which is more expensive and less flexible, or rebuilding cities to be livable without needing vehicle transportation, which isn't happening soon and has trouble for people with mobility issues like the elderly without other some accomodation.
In some places that had trams, electric buses will connect to the tram power lines and charge up a bit (or at least use less of their stored energy) while in those areas.
Bravo but can we not put big-ass stickers on the windows please
What maker?
