Conversion of wind power into wind energy has been utilized for many years. Some examples are:
• Wind turbines to make electricity
• Windmills for mechanical power
• Wind pumps for drinking, irrigation or drainage
• Sails to propel ships
A windmill converts the energy in the wind into electrical energy or mechanical energy to pump water or grind cereals. The most common windmills in operation today generate power from three-blade, horizontal-axis windmills with the nacelle mounted on steel towers that can be cylindrical steel plate or lattice towers.
