TDW,

China is not ramping up coal based power. Coal use in China peaked in 2013. This accounts in part for the fact that global coal prices are now in the toilet. China is ramping up solar and wind energy faster than any other country. Chinese oil and natural gas consumption are still rising. China still has a lot of work to do to curtail emissions. This process is in going and will involve, among other things, more reliance on renewable based electricity and more EVs. China is not a democracy so these changes can be invoked rather quickly.
