Electric Buses Are Hurting the Oil Industry (bloomberg.com)
An anonymous reader quotes a report from Bloomberg: Electric buses were seen as a joke at an industry conference in Belgium seven years ago when the Chinese manufacturer BYD showed an early model. Suddenly, buses with battery-powered motors are a serious matter with the potential to revolutionize city transport -- and add to the forces reshaping the energy industry. With China leading the way, making the traditional smog-belching diesel behemoth run on electricity is starting to eat away at fossil fuel demand. The numbers are staggering. China had about 99 percent of the 385,000 electric buses on the roads worldwide in 2017, accounting for 17 percent of the country's entire fleet. Every five weeks, Chinese cities add 9,500 of the zero-emissions transporters -- the equivalent of London's entire working fleet, according Bloomberg New Energy Finance. All this is starting to make an observable reduction in fuel demand. And because they consume 30 times more fuel than average sized cars, their impact on energy use so far has become much greater than the than the passenger sedans produced companies from Tesla to Toyota. For every 1,000 battery-powered buses on the road, about 500 barrels a day of diesel fuel will be displaced from the market, according to BNEF calculations. This year, the volume of fuel buses take off the market may rise 37 percent to 279,000 barrels a day, about as much oil as Greece consumes, according to BNEF.
Those electric buses are not yet zero emission in China - where most of the electricity is generated by coal.
They can be zero emission, when solar- or hydro-powered.
Diesel buses will never be zero emission.
But after you have the electric bus, you must close the coal mine, turn off the gas pipeline, and shut down the thermal power plant. Otherwise you just moved the emissions around a little.

Vancouver, BC has a fairly large electric bus system, and has had it for over 50 years. The trollybus system covers most arterial routes, and while the buses are primarily powered off the overhead wires, they can go for short distances (under 1km IIRC) on internal batteries. The latter capacity is primarily used to get around detours or accidents.
With one of these systems, your buses are as clean as your power supply, and you don't need to muck around with expensive/polluting batteries to the same degree.

"Perfect" should not be the enemy of "good".
I've been spending a month or two a year in China for the last decade or so, and the air there is definitely a lot cleaner than it was in 2007.
As another poster already pointed out, it's heaps easier to put one scrubber on one smokestack than it is to put a million of them on a million automobiles. And it seems to be proving effective.
Il n'y a pas de Planet B.
...is to create a comprehensive network of electrically powered public transport infrastructure. Spain is already the country with the highest per capita number of high-speed rail Km's in the world, and most EU countries now have extensive electric rail networks. Diesel public transport, by comparison, is slow, heavy, unreliable, and expensive but even that's cheaper and cleaner than individuals driving themselves to work each day.
American-style suburbia, with its heavy reliance on individuals driving themselves to work, is one of the most inefficient and polluting urban planning models devised in recent history. It's also an obscene waste of people's time when they have to sit idling in traffic jams every day.
On the other hand, China is by far the most aggressive investor in renewable energy. India isn't dragging its feet either. The USA is getting left behind and falling even further behind with its current stable genius in the Whitehouse. Without a sensible, well-informed, coherent energy policy, guess who's heading for a 2nd world economy pretty soon?
Debate is a form of harassment. Do not question my truth.
It's just a reaction to the endless criticism whenever America does something virtuous. A thousand comments immediately point out that America's not perfect and doesn't deserve any praise while so many problems remain. Now it's China, but suddenly it's okay to applaud them despite China's horrible record. A double standard.
Shutting down free speech with violence isn't fighting fascism. It IS fascism!
yep.
Not to mention on individual vehicles you get yahoos removing emission reducing equipment (such as catalytic converter) for a slight improvement in performance or those fucks in diesel trucks wanting to 'roll coal' and leave a huge smokescreen behind them.
Given that world oil production is around 35 billion barrels a year, 279,000 barrels isn't even a blip on anyone's radar.
96 million/day
so about a third of a percent.
but if it's an accelerating trend (7 years to 1/3 percent, 8 years to .4 percent), and it's not a proven tech, so it may spread to other countries, I bet they're watching it with some nervousness.
If it can handle buses, local delivery is next (Tesla truck for example).
growth 2016-2017 was .7%, so this in theory is hitting growth significantly.

Bring back jobs to the Pennsylvania coal minors
No kidding. Those little bastards always want the newest iPhone. I say we should eliminate the child labor laws and make them work in the mines to earn the money for those $800 phones. It's obvious that that's where they want to be anyhow. Just look at how popular Minecraft was. If we tell them that it's "double super ultra HD 8K+" resolution, and we throw a couple of rabid dogs dressed as zombies in the mix they'll be lining up to "play" in the mines.
Most high flow cats (including mine) require MIL eliminators.
In the VAG/Bosch world, that could be programmed away. I don't know about your rustang. The only car I ever put a high-flow cat on only had one O2 sensor, a pre-OBD-II 240SX. That was CARB legal. Now I'm driving a pre-facelift D2 A8, which has the same exhaust they used on the S8 which tells me I don't need any more of it and it's definitely not limiting output. Post-facelift cars have cats and pre-cats. However, for all D2 A8s there are software fixes to patch away the downstream cats entirely so that you can run whatever you want, or nothing...
"You're right," Fisheye says. "I should have set it on 'whip' or 'chop.'"
I actually encountered a truck rolling coal when I was in Georgia for a conference a while back. Apparently a pedestrian walking on a road rarely used by pedestrians was enough to to be deliberately hit with a blast. Frankly, not only is rolling coal gross and damaging to the environment as a whole, the deliberate blast settings should constitute assault.
Burning a flag -> hateful political speech
Burning a flag such that the burning embers purposely fall on someone and risk hurting them -> assault
.. where regenerative braking can put the energy back into the battery. They are also big, so have room for lots of cells. And most cities number their busses for the peak morning and evening rush, so there's plenty of opportunities to schedule each bus off the road for 2 hours to fully charge it.
But busses are only the start. All the problems with electric vehicles have been solved - we just need to ramp up battery production. All that remains to be seen is if the electric takover will be the major car manufacturers will writing off their investment in the internal combustion engine, or whether a raft of new automotive companies will take over.
So the rest of use aren't going to want gas much longer.

China is 20% of the world's population. Even if they punch way below their weight, in a serious bid for technological leadership sheer size.
Consider Liechtenstein. It may be a terrific place to live -- in fact it's got the world's highest per capita income $139,100. But with just 39,000 inhabitants, it's never going to be a world power at anything.
Now the United States is the third most populous country in the world. Our world-leading higher education system means we punch way above our weight. But realistically we're only 5% of the world's population. To put that in perspective, India, the second most populous country, may have a huge poverty problem, but its middle class (267 million) is larger than the US middle class (121 million). Within the next decade, the size of the Chinese middle class is expected to outstrip the size of the entire US population.
So the only way we're not going to lose ground to China on technological leadership is if China screws up badly. Or we make a really concerted effort to step up our game. Possibly both would be needed. The thing is, I don't think Americans realize this; we think of tech leadership as a birthright. People would be amazed to realize that other countries have better Internet, better phone, and better health care than we do.
