explain about wind power? long question answer
Answers
Answer:
Wind power or wind energy is the use of wind to provide the mechanical power through wind turbines to turn electric generators and traditionally to do other work, like milling or pumping. Wind power is a sustainable and renewable energy, and has a much smaller impact on the environment compared to burning fossil fuels.
Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network. Onshore wind is an inexpensive source of electric power, competitive with or in many places cheaper than coal or gas plants Onshore wind farms also have an impact on the landscape, as typically they need to be spread over more land than other power station and need to be built in wild and rural areas, which can lead to "industrialization of the countryside" and habitat loss Offshore wind is steadier and stronger than on land and offshore farms have less visual impact, but construction and maintenance costs are higher. Small onshore wind farms can feed some energy into the grid or provide electric power to isolated off-grid locations
The wind is an intermittent energy source, which cannot make electricity nor be dispatched on demand. It also gives variable power, which is consistent from year to year but varies greatly over shorter time scales. Therefore, it must be used together with other electric power sources or storage to give a reliable supply. As the proportion of wind power in a region increases, more conventional power sources are needed to back it up (such as fossil fuel power and nuclear power), and the grid may need to be upgraded. Power-management techniques such as having dispatchable power sources, enough hydroelectric power, excess capacity, geographically distributed turbines, exporting and importing power to neighboring areas, energy storage, or reducing demand when wind production is low, can in many cases overcome these problems Weather forecasting permits the electric-power network to be readied for the predictable variations in production that occur
In 2018, wind supplied 4.8% of worldwide electricity, with the global installed wind power capacity reaching 591 GW. Wind power supplied 15% of the electricity consumed in Europe in 2019. At least 83 other countries are using wind power to supply their electric power grids.

wind power describe the process by which wind is used to generate mechanical power or electricity . this Main character power will be used for various tasks such as grinding grain or pump in water and can be converted into electricity by generator
