Since wind power generation depends on wind conditions, when there is no wind, the power grid must start some thermal generation units to compensate for the lack of electricity generation caused by the absence of wind. However, getting started takes time. Thermal production units cannot be used as wind energy. Once electricity production is stopped, it is immediately replenished. Therefore, the power grid now requires wind power plants to install battery packs. When the wind suddenly decreases, battery packs can be used. It is relied upon to maintain the power supply for a period of time, allowing other generators to start up and replace the wind turbines.
1. Wind lifting:
Wind lifting has been widely used since ancient times.
2. Wind energy productionnne:
Wind power generation generally has three modes of operation:
(1) This is an independent mode of operation, usually a small generator. is used to produce electricity. One or more households provide electricity, which uses batteries to store energy to ensure energy consumption when there is no wind.
(2) Wind power generation is combined with other power generation methods (such as diesel engine power generation) to provide electricity to a unit, a village or an island.
(3) Wind energy production is integrated into the conventional electricity grid to supply the large electricity 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. Sailing to aid navigation:
In the development of today's motorboats, 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 thermal energy for household energy is increasing, especially in the high latitudes of Europe and North America. Drinking water is a large consumer of energy. In order to meet the thermal energy needs of households and small-scale industries, wind heating has been considerably developed.

Advantages and disadvantages of wind energy
1. Advantages
Wind is a clean energy source. Wind installations have become more advanced, mass production has reduced costs, and in the right places, wind power is now cheaper than other generators. The installationsWind turbines are mostly non-three-dimensional installations that can protect land and ecology. Wind energy is a renewable, clean and environmentally friendly energy source. Wind power is energy efficient and environmentally friendly.
2. Disadvantages
The ecological problem with wind power is that it can disturb birds. For example, grouse in Kansas, USA, gradually disappeared after the emergence of wind turbines. The current solution consists of producing electricity at sea, which is more expensive but also more efficient.
In some regions, the profitability of wind energy production is insufficient and the wind is intermittent in many regions. What's worse is that in places like Taiwan, there is less wind in summer and during the day. when energy demand is high, we must wait for the development of energy storage technologiesenergy 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 emit a huge noise, so find an open space to build on.
Current wind production is not yet mature and there is still considerable room for development.
