Energy revolution highlighted at expo

TAIYUAN - Instead of going to a market for building materials, a man surnamed Jiang from Taiyuan, Shanxi province, headed to the 7th China International Energy Industry Expo to find decorations for his new apartment.

At the expo, which opened recently, Jiang was interested in marble-like tile, made from a recycled material - a byproduct of coal burned for electrical power.

An oddly-shaped, fist-sized black ball displayed on a nearby stand also grabbed Jiang's attention. It was solid fuel made of household waste, used for power generation and heating boilers.
