Wind power is the use of wind energy to generate useful work. Historically, wind power was used by sails, windmills and windpumps, but today it is mostly used to generate electricity. This article deals only with wind power for electricity generation. Today, wind power is generated almost completely with wind turbines, generally grouped into wind farms and connected to the electrical grid.

6 FAQs about [Wind power generation s utilization of wind]
What is wind power?
Wind power is a form of energy conversion in which turbines convert the kinetic energy of wind into mechanical or electrical energy that can be used for power. Wind power is considered a form of renewable energy. Modern commercial wind turbines produce electricity by using rotational energy to drive a generator.
What percentage of electricity is generated by wind?
Wind energy generation accounted for 24% of total electricity generation (including renewables and non-renewables) in 2020; with offshore wind accounting for 13% and onshore wind accounting for 11%. Data on energy generation is from the UK Department of Business, Energy and Industrial Strategy's Energy Trends. 4. Business activity in wind energy
Is wind power a viable alternative energy source?
The use of renewable energy resources, especially wind power, is receiving strong attention from governments and private institutions, since it is considered one of the best and most competitive alternative energy sources in the current energy transition that many countries around the world are adopting.
