There are two main types of wind wheels: horizontal axis wind wheels and vertical axis wind wheels. Horizontal axis wind wheels have the blade rotating on a horizontal shaft. Vertical axis wind wheels have the blade rotating on a vertical shaft.
Horizontal axis wind wheels are more common than vertical axis wind wheels. This is because they are more efficient at converting the energy of the wind into mechanical power. However, vertical axis wind wheels have some advantages over horizontal axis wind wheels. They are less likely to be damaged by strong winds, and they can operate in areas where the wind direction is not constant.
Wind wheels are a renewable source of energy. This means that they do not produce any greenhouse gasses or other pollutants. Wind wheels are also a cost-effective way to generate electricity.
Wind wheels are playing an increasingly important role in the world's energy mix. As the world moves towards more sustainable sources of energy, wind wheels are likely to become even more popular.
