Coal provided electricity to power electric powers ends up _still_ being cleaner than ICEs, which are just about the worst in efficiency or cleanliness as you can get.

Coal releases lead, radon, and other toxic pollutants into the environment. And you haven't supported the assertion that coal-powered EVs emit less CO2, and it contradicts what I've generally heard elsewhere.

ICEs release all kinds of toxic gases and particulates too, only they do right where people breathe. Coal plants can be build farther away.

Since transit buses are on fixed routes, I wonder why they didn't go with trolleybuses instead - no expensive batteries to replace (trolleybuses do have vestigial batteries, but they're much smaller and used for backup), thus better power-to-weight ratio, no need to wait for charging, and otherwise just as if not more environmentally friendly. When I was in Beijing, there were plenty of those. (I know the ultimate so…

They are quickly phased out, even in Beijing. Most for flexibility I think. Beijing has several thousands of bus lines which pretty covers all major or semi major roads, some of them may use freeways also. Technically you can put overhead wires for all of them, however they may be also expensive and hard to maintain. SF's public transit system is like a toy compared to Beijing's. SF's is more like several double ended trees. BJ's is a real spider web.

Regenerative braking doesn't do much for someone who already throttles properly. Garbage trucks dont have to drive in traffic. They dont get free energy for regen breaking..its just a recoup for bad driving conditions.

Were I live buses do drive in traffic.

Yes, buses do. But not garbage trucks...Please read my post again - I never referred to buses, only garbage trucks.

Why is the US not investing in these kinds of infrastructure build outs? I’m not trying to start a flame war, I’m generally curious. I understand the path dependence that, for example, made the US adopt mobile phones much later than everybody else (a modern and high quality wire plant that wasn’t yet amortized). Things like that make things like train networks hard to build too. But bus fleets turn over relatively qu…

The U.S. legislative system has to cater to everyone's interests. Which is not bad per se, but when it comes to something like this, new environmental laws will always hollow out an entire industry. No matter what new enforcement they try to enact, there'll always be someone powerful lobbying against it.

>>The U.S. legislative system has to cater to everyone's interests.

I'd argue that clean air and water are in everyone's interest.

Hong Kong maybe. The great firewall is really the party shooting itself in the foot.

The Chinese market is big enough to build very successful companies that never need to cross the firewall to provide their services.

Correct, you have a 1 Billion+ market for your goods & services. In addition, look at Tencent and Alibaba, I believe they are offering services outside of China just fine.

The Chinese market has to deal with obnoxious barriers to starting a business and competition from government backed giants (tencent, alibaba). So long as the party shoots itself in the foot it will never replicate Silicon Valley.

Living in Shenzhen, it feels like probably 80% of the taxis are electric already. Due to government subsidy the blue electric BYD cabs are more spacious, cheaper (no 2元 fuel surcharge), newer and cleaner than the older red cabs, which are generally clunky dirty squashed VWs. However, the drivers pay more to buy them even with subsidy, and you need a conventional ICE vehicle to get out to the factories in Dongguan, or…

I wounder how it would effects the earning of those taxis drivers? Can switching to electric cab increase their income?

It will be really great too see their income (Not just financially) increased by switching to electric vehicles. Because that could give people stronger motive do to this kind of switch than government subsidy.

A taxis company in our city renewed their cabs recently, unfortunately they picked rather old cheap tech cabs that burning petrol + natural gas. If Shenzhen's taxis companies and drivers can receive benefits from such, everybody will eventually follow the trend.

Shenzen / Hong Kong will be the next Silicon Valley.

It already is, but with a lot less bureaucracy. People get things done much quicker there

Yeah, it's easy to get things done fast when you can completely ignore the collective intellectual property rights and trademarks of whole countries, and steal designs and manufacture counterfeit goods wholesale!

Beijing and Shenzhen are already considered “SV” of China. HK? Far from it. The governement has very little push and clues to make HK a SV.
