On Thursday, China released its first white paper mapping the country's energy transition over the past ten years. The paper shows that China's energy intensity decreased steadily, reducing CO2 emissions by three billion tons. Last year, China invested 676 billion USD in the energy transition, the largest in the world, and more than the U.S. and the EU combined. What exactly are the numbers telling us? What's driving this revolution? And what impact is this having on the world?
