  • China now consumes nearly as much coal as the rest of the world combined. And perhaps it always did: it seems coal was routinely burned 3500 years ago in what is now China--the earliest evidence people have for the practice. John Dodson at the Australian Nuclear Science and Technology Organisation in Sydney, and his colleagues in China, were examining early evidence of bronze casting in northern China when they found chunks of burned coal in the ancient slag piles instead of the charcoal they expected. The results confirmed that coal had been burned in the area around 3,500 years ago.
