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.

I'm guessing the units should've been 'KW' rather than 'KWh' but the general point is, you have to take into account the energy used to take the oil from the ground and transform it into petrol/diesel ready to be used in cars. In other words, all of the energy used in drilling, refining and transporting should count towards the total energy used.

Shenzen / Hong Kong will be the next Silicon Valley.

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

No. Hongkong now has no chance for that role, and compared with mainland companies there are not much successful Hongkong companies.

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!

They make it cheaper and better don't need to blame them.

Japan did the same after the WW2 and we're not here to say that Japanese technology sucks.

Just watch your phone, it's probably made in China dude.

Buses don't need huge batteries for their size. A typical city bus goes only about 100 miles a day, they do a ton of regenerative breaking, and they can charge at stops and also they tend to sit in the terminal several times a day while the driver takes a break after each circuit. Electric trash collection trucks are even better. That's because they do so much regenerative breaking.

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.

Garbage trucks still need to make frequent stops compared to most vehicles. I suppose it's possible to make some kind of pickup system that doesn't require stopping, like the mail systems trains used to use. I don't know of any place that does that though. It'd probably get messy pretty easily.

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.

Maybe their actual bests interests but not what they THINK their best interests are.

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…

Shenzhen is going whole hog with public transit seems they're opening a couple of subway lines every year at the moment

Agree. Not limit to the energy policy. US politicians are more often doing serious but not quite visible damage to long term interests. Just most modern US citizen are not aware of. There are some exceptions like Taleb Nassim but the voices never go through main stream

Hong Kong might have the education, but its market is too small to make any VCs interested.
