Almost all of those sales are in China though. They're starting to enter Western markets and having some success, mostly by being the cheapest EVs around, but Tesla is still outselling them 4:1 in Australia despite steeper price tags.
Feels like at this point whoever takes the Chinese market gets the crown, and I suppose India will be next in this game.
Why?
India is pretty crowded.
This can be achieved by systematically ban cars from cities. By investing far more into trains then into highways. By having good public transit even to remote places. And by encouraging small vehicles when necessary.
How are you defining 'powered by coal', because China's energy mix isn't 100% coal either.
I'm not saying it's bad to move to electric vehicles just that it's not the wonderful win for global warming in China (or really anywhere else) right now and for the foreseeable future.
Electricity transfer, battery charging, and electric motors are all over 90% efficient, with overall "well to wheel" efficiency around 80%.
