China passed the United States in numbers of new wind turbines built in the first half of 2009, data from Beijing-based specialists Azure International shows, and is also increasing its share of the main solar demand market, Europe.
"I think China is definitely winning the race," said Wu Changhua, China director of the London-based environment body The Climate Group, citing support for low-carbon LED lighting and electric cars as well as wind and solar.
"A low-carbon economy is mainstream thinking," she said, adding that Chinese development was helped by swifter centralized decision-making compared with its rivals.
In wind power, local demand often means local jobs — that's especially true in China where an unofficial rule says all installed turbines must include 70 percent local content.
International companies' market share there is falling.
"In the first half (of 2009) that decline continued," said Sebastian Meyer, head of research at Azure International.
Tough financing markets plus falling oil prices have dented clean energy prospects worldwide and created a glut of turbines and solar panels, with recovery expected from next year, aided by new stimulus programs.
