Also of note is that Japan and Russia (the two previous "challengers" to US economic supremacy that some like to compare China to) were not even close to half of US electricity generation during their respective peaks.
Great point. And those countries became challengers when their economies matured.
China has already beaten the US as a developing economy and is consuming twice the electricity of the US with a lot of room to grow.
A maturing China in the coming decades will expand the difference far more.
Look at the slope (delta) of the growth rates between the two countries. China's rises up like Mount Everest compared to the US (and the rest of the world.) China is blowing every other country out of the water and is doing it basically as a teenager who haven't even fully matured yet.
