The wind turbine needs a blade to cut into the wind speed. If the wind speed is greater than the blade cut into the wind speed, the wind turbine unit can generate electricity. The amount of power generated is closely related to the size of the wind speed. Simply put, if the wind is strong, the power will be more, and if the wind is small, the power will be less. There are several The fan unit depends on the installed capacity and model. I hope it can help you
1. Wind water lifting:
Wind water lifting has been widely used since ancient times.
2. Wind power generation:
Wind power generation usually has three operating modes:
(1) It is an independent operation mode, usually a small generator is used to generate electricity. One or several households provide electricity, which uses batteries to store energy to ensure power usage when there is no wind.
(2) Wind power generation is combined with other power generation methods (such as diesel engine power generation) to provide power to a unit, a village or an island.
(3) Wind power generation is integrated into the conventional power grid to provide power to the large power grid. Often dozens or even hundreds of wind turbines are installed in a wind farm, which is the main development direction of wind power generation.
3. Sail to assist navigation:
In the development of today's motor boats, in order to save fuel and increase speed, ancient sails have been developed.
4. Wind heating:
With the improvement of people's living standards, the demand for heat energy in household energy is increasing, especially in high latitudes in Europe and North America. Drinking water is a major energy consumer. In order to solve the heat energy needs of households and low-level industries, wind heating has been greatly developed.

Wind energy advantages and disadvantages
1. Advantages
Wind is a clean energy source. Wind energy installations have become more advanced, mass production has reduced costs, and in the right locations, wind power is now less expensive than other generators. Wind energy facilities are mostly non-three-dimensional facilities that can protect the land and ecology. Wind power is a renewable energy source that is environmentally friendly and clean. Wind power is energy-saving and environmentally friendly.
2. Disadvantages
The ecological problem of wind power is that it may disturb birds. For example, the grouse in Kansas, USA, have gradually disappeared after the emergence of windmills. The current solution is offshore power generation, which is more expensive but also more efficient.
In some areas, the economics of wind power generation are insufficient, and the wind in many areas is intermittent. What is worse is that in places such as Taiwan, there is less wind in summer and during the day when power demand is high. time; must wait for the development of energy storage technologies such as compressed air.
Wind power generation requires a large amount of land to build wind farms to produce relatively large amounts of energy.
When wind power is generated, the wind turbine will make a lot of noise, so it is necessary to find some open space to build.
Current wind power generation is not yet mature and there is still considerable room for development.
