The USA could have been the driving force behind world transport/renewable electrification, but we didn't have the political will nor the insight.
Much like VHS videotape and the transistor radio, the US invented something, looked at it, said "meh", and continued doing what we were doing. Another country (Japan before, China now) looked and said "Ooooooh, we can use that!" Japan also did a similar move with small, excellent cars when the US couldn't be bothered.
China realized there's no future in polluting with coal nor in buying oil - it's a mug's game.
They made a calculated political decision to take over the world solar market, and to be the driving force behind world electrification. (Maybe something only possible in a command economy.)
Result? Lots of money coming into China for solar panels and electric cars / bikes. Economic destruction of the petroleum car and petroleum extraction industries. The world looking to China as the provider of energy needs, instead of the US and the Middle East.
Oh, and BTW, much cleaner air and water, and maybe slowing down climate change.
