I see a lot of news of these "green" vehicles being used in China but few seem to be questioning where that electricity comes from. Coal power is still a massive thing in China.

Hills are the primary use case for electric buses already (electric has much better torque), and have been for a very long time. The only thing is now instead of using overhead lines, batteries can be used instead.
The comparison of how much faster our electrified trolley busses here in hilly Seattle compared to traditional busses is pretty stark, the instant, linear torque is really hard to come close to equaling with a combustion engine. eBikes with mid-drive motors like the BBSHD also have this kind of torque, it can be really fun to ride them due to that. With electric motors, you choose between torque and top RPMs based on…
It is a combination of electric and rubber. Even tram/light rail lines use that combo (eg Lausanne’s M2).

#153Electric buses seem to be fairly common in UK city centres. I first saw one in London about 4 years ago - it was surreal when walking past a typical red double decker at a bus stop and it just glided away with the faintest whirr.
I’m all for buses and taxis turning electric to reduce the diesel fumes in cities.

It looked like a surprise for some posters here, yeah, they seem to didn’t know that the same has been happening in the West since as early as the late 1700s-early 1800s and I’d say it’s still happening. The West is not being criticized as much as it should today for repeating the same mistake it has been doing again and again for almost two centuries now. Later edit: This forest which got knocked out during a recent…
The Irish Times article is highly critical of the West doing the same today. What's the difference between that and the Yale 360 article linked further above? Edit: In response to your edit. Are you sure that isn't native woodland? I would expect the higher reaches of a mountain to be pine trees. The article mentions Stradivarius, violins are made of spruce amongst other woods. Plus those forests are obviously somewh…
> Are you sure that isn't native woodland?
Hard to tell 100% without being present on site but that's my guess, yeah. I've very rarely seen "natural" forests being completely wiped out like this as a result of strong winds, the worst that can happen is some older trees being knocked down here and there, but, as I said, I've not yet seen "natural" forests being completely knocked down as a result of one wind-storm.
I also suspect those were planted forests because you cannot use that wood as raw material for Venice's Arsenal for centuries past without planting something in return. I suspect the planting continued even after the Arsenal itself and wood-shipping in general were no longer a thing.

Source?
It actually says as much in the article linked by grand parent, but I also remember reading about it a few years ago in china daily or globaltimes (probably the latter), so it has been brought up in the Chinese press as well. Anecdotally as well: I was living in Beijing during the entire time period and noticed the dust storms going away and then coming back. Fun story: Beijing kids are all required to plant trees on…
I remember reading a Caixin article that says the plant they use in the north to fight desertification actually causes massive allergy to the population that are traditionally pretty healthy.

#156What's the advantage compared to a tram or trolley bus? I don't get it.
No need to build and maintain the infrastructure (rail and overhead power lines.) The ability to navigate the road freely -- trolley buses often have trouble circumnavigating badly parked cars in their way, sometimes causing the driver to get out to reattach the "prongs" to the wires. Also, trams are somewhat prone to "tram jams" caused by one faulty streetcar blocking the railway. And they simply cannot get around a…
Trolley buses also have to slow down at intersections to avoid coming unhooked.

#157"Forget Tesla" is the wrong attitude. We should applaud every win we can get, big or small.
We should celebrate what makes things available to everyone, not just to rich clients. Tesla is still far away from selling cars to everyone.
Why? Are poor people immune to the pollution emitted by a rich person's ICE vehicle? Even if we assume a fully fossil power generation grid, at least the inhabitants of the same city are not breathing as much crap, and that's a huge plus.
Re: China's e-buses dent oil demand more than electric cars do
#158By this logic, we should "forget" all the go green initiatives because China (and Africa) are building a "Green Wall" to stop their respective deserts from widening. https://news.nationalgeographic.com/2017/04/china-great-gree... I say this is mainly about China because Africa has modified their green wall project and instead of planting billion trees from East coast to West coast, they are helping communities to thr…
Wait, what logic says we should give up everything just because China planted some trees?

The price of oil is unrealistic, because it does not reflect the terrible damage to our planet. In other words, the current price can be so low because we are "borrowing" the planet from our children and grandchildren. We get cheap oil because they will not have a planet to live on. If the price were to include a carbon tax, it would likely be at least ten times higher and we would very quickly get rid of our beloved…
>If the price were to include a carbon tax, it would likely be at least ten times higher and we would very quickly get rid of our beloved gas guzzlers. Wouldn't you expect a carbon tax to be similar in price to the cost to get the carbon back out of the air? CO2 released per barrel of oil (when converted to various fuels and burned) appears to be around 300-450 kg [1][2], but we can round up to 500 kg to be conservat…
The thing is, if you wait long enough, CO2 will be removed by the plant life anyway so removing it is "free". However if you reflect the price of the removal process which is as _fast_ as it is emitted to the consumer, someone gonna pay through the nose...

How many days was Kuwait over 130F last year?
Most days May through September experience an average high of actual temperature of around 120F each day with 100% sunshine. Its the heat index that brings it up to about 140F. You have to understand that during the summer here there is relatively lower humidity during peak sunlight which refracts less light before hitting the ground. The ground here is also highly reflective of heat, which is felt at least 5 to 6 fe…
