In nature, the wind turbine is a renewable, non-polluting and enormous reserves of energy. As the ground around the solar radiation after changes in different temperature and water vapor in the air in different, hence the difference in air pressure around the cause, in the direction of the level of high-pressure air flow to the low pressure area that formed the wind. Decided to wind energy resources can make use of wind energy density and wind energy, the cumulative number of hours. Wind energy density is upwind of units available to wind power, wind speed and the three and the air density is directly proportional relationship.
The use of wind energy is the main driving force for wind energy and wind power generation in two forms, again mainly wind power.

To make wind power, wind is used to directly promote all kinds of mechanical devices, such as lead, such as water pumps to wind this engine advantages are: less investment and high work efficiency, economic durability. At present, the world's about more than 1 million of the Typhoon aircraft in operation to water. Use of wind power, the first application to Denmark, but also use more common.

First, the world rapid development of wind power installed capacity

1. Abundant reserves of the world wind energy resources

The world is very rich in wind energy resources reserves. Stanford University civil and environmental engineering in accordance with national meteorological data centres and early warning systems laboratory in the 1998-2002 wind speed and temperature data, the 7753 ground and 446 (including 414 from the ground at the height of 80 ± 20 meters) of space observation Point two different types of data, using the minimum square principle of the global wind energy resources to carry out the statistics and, come to the conclusion: the 80 meters in height, 6.9 m / s to calculate the wind speed, wind power can make use of global resources Volume to 72 trillion kilowatts. Even if only one of the successful use of 20 percent, still the world's energy consumption equivalent to the sum.

2. The rapid growth of wind power installed capacity

1) continued development of wind power technology, costs continued to drop

Industry through technological progress, the cost of wind power has continued to drop. At present, in all kinds of renewable energy, wind power of the lowest cost. National average cost of wind power for 0.50 yuan / (kW h), the total cost of new investment has been close to the water and electricity and thermal power.

Recently, the World Wind Energy Council to further reduce the cost of wind power were analyzed and considered that the declining cost of wind power, 60 percent dependent on large-scale development, 40 percent rely on technological progress. Past the declining cost of wind power is based on more technical progress, and after a further decline in the cost of wind power is more dependent on large-scale, the serialization and standardization. World Wind Energy Council estimates that by 2020, the overall cost of land Fans also may be reduced by 20% -25%, sea fan can reduce the cost of more than 40 percent, power generation costs can be the same rate of decline.

2) the rapid growth of wind power installed capacity

Wind power generation in renewable wind generators  technology is relatively mature, a relatively low cost, by the countries of universal attention, the installed capacity of rapid growth. Since 1996, global total installed capacity of wind power for 12 years the growth rate of more than 20 percent, the average growth rate reached 28.33 percent.

According to the Global Wind Energy Council (GWEC) released the latest data, in 2007 the new global wind power installed capacity of 20073 MW, growth of 32.1 percent. United States (5244 MW), Spain (3522 MW) and China (3449 MW) ranked the top three, in 2007 the global total wind power installed capacity of 94112 MW, growth of 26.8 percent, exceeding the forecast before the GWEC 22.6%. One of China's total of 07 wind power installed capacity has reached 6050 MW, Denmark crowded under a fifth in the world of wind power.

To the difference of view, the European wind power is still the most popular regions, 07 accounted still as high as 61 percent. However, Asia and the United States is the next three years wind energy major source of growth in the market. In addition, North Africa and the Middle East new wind power installed capacity is also growing rapidly. It is worth mentioning is that the Chinese 07 the total installed capacity of wind power installed capacity and add up to 132.3 percent increase, respectively, and 156 percent, the growth rate of cohabitation first in the world.

Second, China wind generators is the world's fastest-growing wind power market

1, China's abundant wind power resources

China's comprehensive use of resources of renewable energy resources professional association with the United States Commission on National Renewable Energy Laboratory (NREL), the United Nations Environment Programme (UNEP) support and funding, some regions of China's wind resources to conduct a detailed calculation.

According to the estimation results, speculated that China's land can be installed with 1.4 billion kilowatts of wind power generation equipment, if we consider the sea, the total volume of resources will reach 2 billion kilowatt above.

China's wind resources are mainly distributed in two major wind belt: First, "Three North" (Northeast, North China and Northwest China); two in the eastern coastal land, islands and coastal waters. In addition, there are still some local inland wind energy resource-rich areas.

"Three North" (the northeast, north, northwest) regions with abundant wind energy, including three northeast provinces and Hebei, Inner Mongolia, Gansu, Qinghai, Tibet, Xinjiang and other provinces, autonomous regions, nearly 200 km wide zone, development and utilization of wind energy reserves About 200 million kilowatts, accounting for the use of reserves to 79%. The wind farm in flat terrain, accessibility, not destructive winds, even as China is one of the largest wind power resources, is conducive to the development of large-scale wind farm.

Wind energy rich eastern coastal areas. The cold air in winter and spring, summer and autumn typhoons, can affect the coastal areas and islands, is the best of China's abundant wind energy, wind power density, effective at 200 watts / sq m and above. Such as Taishan, Pingtan, Dongshan, South deer, big Chen, Sheng Si, South Australia, Matsu, Makung, the Pratas, and so on, can use a few hours in about 7000 to 8000 hours. This region, particularly in the southeast coastal areas, inland from the coast to the rolling hills, wind-rich areas only 50 kilometers from the coast within.
