Development and utilization of wind energy

The industrialization development and utilization of wind energy in the world began in the early 90s of last century. Although the current installed capacity of the global wind power plants is less than 1% of the total installed capacity of the global power generation, the installed speed of the wind turbines has remained above 25% in the past 10 years. From a global perspective, the development of wind energy has been developed from the experimental stage to the industrialization stage. By the end of 2006, the world's new wind power installed capacity of 10 million 200 thousand kilowatts, in the past 5 years, the global wind power installed capacity increased by an average annual rate of more than 26.3%. By 2020, the world's electricity installed capacity will reach 1231GW, generating capacity of about kWh billion, by then, wind power will account for 12% of the world's total electricity.

The unit cost of wind power development is also gradually reduced, the cost of wind power has been from early 80s 38 cents /kWh to 2006 at the beginning of 3 cents (about /kWh the world's major wind farms), is expected to 2010, the world average wind power generation cost will be reduced to 2.6 cents to about /kWh.

Wind power equipment industry continues to show a high growth and monopoly trend. In the 30 global supplier of wind turbine, the world's top 10 suppliers accounted for 2006 all the installed capacity of 94%, ten, 4% market share. Four major suppliers accounted for 80% of the total supply. Denmark Vestas company continues to maintain its leading position, market share increased to 35.2%, Gamesa ranked second, Germany's Enercon GmbH maintained its position of third, the market share of 15.8%. India's Suzlon stands out in sixth place, with a market share of 3.9%.
