Wind is a potential new energy source, and people may still remember that in the early 18th century, a fierce wind swept through England and France, destroying 400 wind mills, 800 houses, 100 churches, and over 400 sailboats. Thousands of people were injured, and 250000 large trees were uprooted. As for the matter of uprooting trees alone, the wind emitted a power of 10 million horsepower (i.e. 7.5 million kilowatts; one horsepower equals 0.75 kilowatts) in just a few seconds! Someone has estimated that the wind resources available for power generation on Earth are approximately 10 billion kilowatts, almost 10 times the world's hydroelectric power generation. The energy obtained from burning coal worldwide every year is only one-third of the energy provided by wind power within a year. Therefore, both domestically and internationally attach great importance to utilizing wind power for power generation and developing new energy sources.
