Thousands upon thousands of windmills, scattered on the prairie in North China's Inner Mongolia Autonomous Region, are bringing joy to some 1 million local farmers and herds people. They were used to the whistling wind but never thought of using it to generate electricity for their own benefit. The wind has become an important resource on the prairie with the erection of wind mill parks. Five such parks have emerged since the late 1980s, and the total installed capacity reached 46,000 kilowatts by the end of last year, generating 100 million kilowatt hours of electrical power annually.
