In a tightly interconnected global economy it is disingenuous to disconnect the energy usage of one country or region from another.
US coal usage goes down because the things we used to build with that energy are now built in China. Solar panels in the US are cheaper than ever because manufacturing has switched to being 80% Chinese production, and guess where the energy to build those solar panels comes from? Coal.
The only way to understand energy is at a global scale as you can see here: https://ourworldindata.org/energy-production-consumption
As you can clearly see no source of energy has decreased overtime globally.
Looking at local energy production is just an accounting trick, but the planet doesn't really care. You can't combat global warming by saying "look, technically we didn't produce that energy on our shores!"
If you forced China to decrease its use of fossil fuels you would immediately feel the impact on the global economy. Just because the power plants aren't within our borders doesn't mean that's not energy being consumed for our benefit.
