There is also hydroelectric, which the US can't grow in anymore because it already tapped all the river locations it could use when the US was industrializing, but China can because it is only fairly recently China had industrialized enough to start tapping its own rivers. Of course, once all the river sites in China are exploited, China's growth in that sector is completely done, so it's almost like a temporary boost more so than a long-term growth factor, for lack of better words.
