The installed capacity of wind power in north China's Inner Mongolia Autonomous Region grew over 40 times to 7.3 million kilowatts by the end of March from 170,000 kw in 2005, figures released Thursday by a local power company showed.

"Around 20 percent of power in the region is supplied by wind as of February. That is close to the level of some of the world's most wind-power-boasting countries like Norway and Denmark," said Zhang Fusheng, general manager of Inner Mongolia Electric Power Corporation.

Inner Mongolia has the most abundant wind resources in China. Wind resources in the region that can be developed by existing technologies have hit 150 million kw, accounting for 50 percent of the country's total wind resources on land, he said.
