Earth's surface air flow generated by the large number of kinetic 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. According to estimates, the world's total wind power about 130 billion kilowatts, China's total wind energy of about 1.6 billion kilowatts. Wind energy resources by a greater impact on the terrain, the world wind energy resources and more concentrated in the coastal and open the mainland areas of contraction, such as the United States of the California coast and the Nordic countries, China's southeast coast, Inner Mongolia, Xinjiang and Gansu area of wind energy resources Also very rich. China's southeast coast and nearby islands of wind energy density of up to 300 watts / m 2 (W/m2) above, 3 to 20 m / s wind, accumulated over 6,000 hours. The best wind resources of inland regions, Inner Mongolia to Xinjiang along the area, wind energy density is 200 ~ 300 W/m2, 3 ~ 20 m / s wind, accumulated 5,000 to 6,000 hours. These areas suitable for the development of wind power and wind to water. Dabancheng, Xinjiang Wind Power Station in 1992 has installed 5,500 kilowatts, is China's largest wind power station
In nature, the wind turbine is a renewable, non-polluting and enormous reserves of energy. With global warming and energy crisis, countries in the world are stepping up efforts to the development and utilization of wind power, to minimize carbon dioxide and other greenhouse gas emissions, protect our planet's survival.
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, about a white world, more than 000 wind machines to water in the operation. Australia's many pastures are provided in this wind machine to water. In many countries rich in wind resources, scientists also use the wind the engine to a grass surface grinding and processing feed, and so on.
Use of wind power, the first application to Denmark, but also use more common. Denmark-year-old, only 500 million population, is the world's largest wind power and wind power generation round of production power, wind round the world 10 are five manufacturers in Denmark, more than 60 percent of the world's wind round of factories in Denmark the use of the technology, Is a veritable "Windmill big country."
By the end of 2006, total world wind power of the top three were Germany, Spain and the United States, the three countries of the world's total wind power generation wind power generation for 60 percent of the total.
In addition, wind power is also gradually into the residential. In the United Kingdom, the wind slowly rotating blades of wind power micro-motor is becoming a new landscape. Home micro-wind energy power generation equipment, will not only provide electricity for a living, saving, is also beneficial to environmental protection.堪称world's "most residential surrounded" by the United Kingdom is well-known environmental organization "Friends of the Earth", the sponsor of Madiweilian Jianzao Cheng's five-year history, its domestic standing before the wind Yuanqiang Shanzhuang a turbine generator, with the The rotation of the blades, from time to time wind into electricity.
China's rich wind resources, development and utilization of wind energy reserves of 1 billion kilowatts. The use of wind energy, particularly on China's coastal islands, traffic inconvenience to the remote mountainous areas, Diguangrenxi grassland pastures, and away from the power grids in rural areas, border areas, as a solution to energy production and life of a reliable way, with very Important significance.
Now, whether in the vast grassland, or Gao Gao in the mountains, we will see a seat to anti-storm hit and stable operation of wind power stations. Whenever the advent of strong winds, the machine will automatically collect Diaozhuan direction, to meet the sharp wind, despite how much wind, how Lai Shi Meng, for all of it, transformed into electrical energy storage, providing people with electricity. In this way, even in the villages and cities far away from the ranch can use electricity, to lead a happy life.
The disadvantages of wind energy
1) winds of instability, the size of the energy instability
2) what can not use wind, severe restrictions on the location
3) wind energy conversion efficiency of low -
4) the technology was not, not universal
5) is a new type of wind energy in response to the use of equipment is not very mature
6) There is no clear policy to vigorously promote the use of wind energy
