Wind energy has been used since thousands of years ago to turn the waterwheel and move the sailing ship.
In 2019, wind energy contributed 6.5% of the total world electricity production.
Modern wind turbines were first developed in 1888 by Charles F. Brush.
The largest wind turbine currently has a propeller diameter reaching 164 meters and can produce power of 12 megawatts.
Wind energy is an environmentally friendly renewable energy source because it does not produce greenhouse gas emissions and does not require fossil fuels.
Wind energy is produced by differences in temperature and pressure in the earth's atmosphere due to heating the sun.
In 2020, China is the largest country producing wind energy with a capacity of 281 Gigawatt.
In 2007, Denmark received more than half of its electricity needs from wind energy.
Wind turbines can produce very noisy sounds, so it needs to be placed far from residential areas.
Wind energy can be produced in various regions, from sea coast to mountainous areas, depending on the wind speed in the area.
