Wind energy is solar radiation formed under the flow

Wind energy is solar radiation formed under the flow.

 

Compared with other energy sources wind energy has obvious advantages, it reserves are large, is 10 times the water, widely distributed, inexhaustible, traffic inconvenience, away from the main power grid islands and remote areas is particularly important. Currently the most common use of wind energy in the form of wind power.

 

There are two ideas of wind power, the horizontal axis and vertical axis wind turbine fan. Horizontal axis wind turbine is widely used at present, the mainstream models for wind power. Wind power. Are people using the most common form of wind energy, since the late 19th century, Denmark has developed into a wind turbine, it is recognized that depletion of oil and other energy sources will only attach importance to the development of wind energy, using the wind to do other things.

 

In 1977, the Federal Republic of Germany in the famous valley of the wind - Schleswig - Holstein Bloom slope Patel built a windmill power the world's largest. The 150-meter high wind turbines, each 40 meters long blade and weighs 18 tons, made with fiberglass.

 

The end of 2009, the global cumulative installed capacity has reached 159 million kilowatts in 2009, total new installed capacity of more than 3 million kilowatts, or 31.9%. From the total installed capacity, the United States has a total installed capacity of 35.16 million kilowatts, tied for first place; China is 26.1 million kilowatts, the second highest in the world.
