The Great China-USA Mystery: How Did America Decouple Growth From Energy?

Since 2010 China has grown GDP by 210% and used 205% more energy to do it. The US grew GDP by 50% but used only 7% more energy. How?

Comparing the China of 2010 to the country we see today supports the claim that its economy has tripled: 50,000 km of high speed rail; 800 formerly poor million people living in their own homes; its dominance of renewables, EVs, 5G, its glittering downtowns, booming economy and happy citizens..

But evidence of America’s 50% claimed economic growth is scant. No new weapons system this century; life expectancy below – and infant mortality above–China’s; hundreds of thousands homeless.. evidence of contraction, not growth.

As EVs demand ever more electricity, the competition for energy between large AI companies and regular households is already creating political turmoil, raising the prospect that China’s abundant electricity will overcome the disadvantage of its slower chips. Says Bruno Macaes, “AI power demand is exploding, with data centres expected to account for 12% of total electricity use in the US by 2030, while the same forecasts see Chinese data centers consuming 4% by 2030, a much more sustainable fraction. The reason for China’s better trajectory is, of course, renewables, a source of cheap and quickly scalable energy production, now mobilised across Xinjiang and Tibet in solar and wind farms as large as cities”.

America’s decoupling—robust growth with minimal energy uptick—defies basic economic principles and suggests inflated metrics rather than genuine expansion.
