The growth of hydro generation over the last five years is equal to all the other renewable technologies combined, mainly because of the immense Chinesedam projects.
Chinese troops have repaired a dam cracked in this week's earthquake, but officials remain concerned about the damage to reservoirs in the devastated Sichuan province.
The Chinese government sent about 2, 000 soldiers to make the repairs to Zipingku Dam on Wednesday, fearing that it might collapse and flood the hard-hit city of Dujiangyan, according to a statement on the Sichuan government Web site.
Still, the reservoir behind the dam was emptied to relieve pressure on the structure, the state-sponsored Chinese business news magazine Caijing reported.
